Understanding Multiple Sclerosis: A Comprehensive Overview
Multiple sclerosis (MS) is a complex autoimmune condition that affects the central nervous system, specifically targeting the brain and spinal cord. This chronic illness can manifest in various ways, leading to a wide range of symptoms that can significantly impact an individual’s quality of life. While MS is most commonly diagnosed in younger adults, it’s crucial to understand that it can develop at any age.
What is Multiple Sclerosis?
Multiple sclerosis occurs when the immune system mistakenly attacks the protective covering of nerve fibers, known as the myelin sheath. This damage disrupts the normal transmission of nerve signals, resulting in a variety of neurological symptoms. The severity and progression of MS can vary greatly from person to person, with some experiencing mild symptoms and others facing more severe disability.
The Age Factor: Can MS Strike at Any Time?
While MS is typically diagnosed in individuals between the ages of 20 and 40, it’s important to recognize that the condition can manifest at any stage of life. Children, teenagers, and older adults can all be affected by MS, though it’s less common in these age groups. The prevalence of MS is notably higher in women, with a ratio of approximately 2-3 females for every male diagnosed.
Why is MS More Common in Certain Age Groups?
The reasons behind the higher incidence of MS in young adults are not fully understood. However, researchers believe that a combination of genetic predisposition and environmental factors may contribute to the onset of the disease during this period of life. Hormonal changes, exposure to certain viruses, and lifestyle factors may also play a role in triggering the autoimmune response that leads to MS.
Recognizing the Symptoms: Key Indicators of Multiple Sclerosis
The symptoms of multiple sclerosis can be diverse and unpredictable, often varying from person to person. Some individuals may experience mild symptoms that come and go, while others may face more severe and persistent challenges. Understanding these symptoms is crucial for early detection and management of the condition.
- Fatigue: Overwhelming tiredness that interferes with daily activities
- Vision problems: Blurred vision, double vision, or partial vision loss
- Mobility issues: Difficulty walking, balance problems, or muscle weakness
- Numbness and tingling: Sensations typically affecting the limbs or torso
- Cognitive changes: Difficulties with memory, concentration, and problem-solving
- Bladder and bowel dysfunction: Urinary urgency, frequency, or constipation
- Muscle spasms and stiffness: Involuntary muscle contractions and rigidity
- Pain: Chronic pain syndromes or acute pain episodes
How Do MS Symptoms Differ Across Age Groups?
While the core symptoms of MS remain consistent across age groups, their presentation and impact can vary. Younger patients may initially experience more inflammatory symptoms, such as optic neuritis or sensory disturbances. In contrast, older individuals might face a more progressive form of the disease, with a gradual accumulation of disability over time.
Diagnosing Multiple Sclerosis: The Path to Clarity
Diagnosing multiple sclerosis can be challenging, as its symptoms often mimic those of other neurological conditions. A comprehensive diagnostic approach is essential to confirm the presence of MS and rule out alternative explanations for the symptoms.
What Steps Are Involved in Diagnosing MS?
- Medical history review: Detailed discussion of symptoms and their progression
- Neurological examination: Assessment of reflexes, coordination, and sensory function
- Magnetic Resonance Imaging (MRI): Visualization of brain and spinal cord lesions
- Lumbar puncture: Analysis of cerebrospinal fluid for MS-specific markers
- Evoked potential tests: Measurement of nerve response to visual, auditory, or sensory stimuli
- Blood tests: Exclusion of other conditions that may mimic MS symptoms
The diagnosis of MS typically requires evidence of damage in at least two separate areas of the central nervous system, occurring at different times. This criterion, known as “dissemination in space and time,” helps distinguish MS from other neurological disorders.
Types of Multiple Sclerosis: Understanding the Variations
Multiple sclerosis is not a one-size-fits-all condition. There are several distinct types of MS, each characterized by its own pattern of progression and symptom presentation. Understanding these different forms is crucial for developing appropriate treatment strategies and managing patient expectations.
What Are the Main Types of MS?
- Relapsing-Remitting MS (RRMS): The most common form, characterized by clearly defined attacks followed by periods of partial or complete recovery.
- Secondary Progressive MS (SPMS): Often develops in individuals with RRMS, marked by a steady worsening of symptoms with or without relapses.
- Primary Progressive MS (PPMS): Characterized by a gradual, steady worsening of neurologic function from the onset of symptoms, without early relapses or remissions.
- Progressive-Relapsing MS (PRMS): A rare form that shows steady disease progression from the beginning, with acute relapses but no remissions.
Each type of MS requires a tailored approach to management and treatment. For instance, RRMS often responds well to disease-modifying therapies that can reduce the frequency and severity of relapses, while progressive forms may focus more on symptom management and rehabilitation strategies.
The Causes of Multiple Sclerosis: Unraveling the Mystery
Despite extensive research, the exact cause of multiple sclerosis remains elusive. Scientists believe that MS results from a complex interplay between genetic susceptibility and environmental factors. This interaction triggers an abnormal immune response, leading to the characteristic damage to the myelin sheath.
What Factors Contribute to the Development of MS?
- Genetic predisposition: Having a close relative with MS increases the risk, though no single gene has been identified as the cause.
- Environmental factors: Vitamin D deficiency, exposure to certain viruses (e.g., Epstein-Barr virus), and smoking have been associated with increased MS risk.
- Geographic location: MS is more prevalent in regions farther from the equator, suggesting a possible link to sunlight exposure and vitamin D levels.
- Hormonal influences: The higher prevalence in women points to a potential role of sex hormones in MS development.
- Autoimmune dysfunction: An abnormal immune response leads to the destruction of myelin in the central nervous system.
Understanding these risk factors can help in developing preventive strategies and identifying individuals who may benefit from early screening and intervention.
Treatment Options for Multiple Sclerosis: Managing Symptoms and Slowing Progression
While there is currently no cure for multiple sclerosis, a range of treatment options are available to manage symptoms, reduce the frequency of relapses, and slow the progression of the disease. The choice of treatment depends on the type of MS, the severity of symptoms, and individual patient factors.
What Are the Main Approaches to MS Treatment?
- Disease-Modifying Therapies (DMTs): Medications that aim to reduce inflammation and slow the progression of MS. These include injectable, oral, and infusion treatments.
- Symptom Management: Targeted treatments for specific MS symptoms such as fatigue, pain, spasticity, and bladder dysfunction.
- Rehabilitation: Physical therapy, occupational therapy, and speech therapy to maintain function and improve quality of life.
- Lifestyle Modifications: Diet, exercise, stress management, and other lifestyle changes that can positively impact MS symptoms and overall health.
- Alternative and Complementary Therapies: Acupuncture, massage, yoga, and other complementary approaches that may provide symptom relief for some individuals.
It’s important to note that treatment plans are highly individualized and may evolve over time as the disease progresses or new therapies become available. Regular follow-ups with a neurologist specializing in MS are crucial for optimal management of the condition.
Living with Multiple Sclerosis: Strategies for Coping and Thriving
A diagnosis of multiple sclerosis can be life-altering, but it doesn’t have to define an individual’s future. With proper management and support, many people with MS lead fulfilling and productive lives. Developing effective coping strategies is essential for maintaining physical and emotional well-being.
How Can Individuals with MS Improve Their Quality of Life?
- Education and self-advocacy: Learning about MS and actively participating in treatment decisions
- Support networks: Connecting with others who have MS through support groups or online communities
- Stress management: Practicing relaxation techniques, mindfulness, or engaging in hobbies
- Adaptive technologies: Utilizing assistive devices and home modifications to maintain independence
- Regular exercise: Engaging in appropriate physical activities to maintain strength and flexibility
- Cognitive training: Participating in activities that challenge and stimulate the mind
- Nutrition: Following a balanced diet that supports overall health and may help manage MS symptoms
- Sleep hygiene: Prioritizing good sleep habits to combat fatigue and support overall well-being
By adopting a proactive approach to managing MS, individuals can often maintain a high quality of life and continue pursuing their personal and professional goals. It’s important to work closely with healthcare providers to develop a comprehensive care plan that addresses all aspects of living with MS.
Research and Future Prospects: Advancing MS Treatment and Care
The field of multiple sclerosis research is rapidly evolving, with new discoveries and treatment approaches continually emerging. Scientists and clinicians are working tirelessly to better understand the underlying mechanisms of MS and develop more effective therapies.
What Are the Most Promising Areas of MS Research?
- Neuroprotection and remyelination: Developing treatments that protect nerve cells and promote myelin repair
- Personalized medicine: Tailoring treatments based on individual genetic and biomarker profiles
- Stem cell therapies: Exploring the potential of stem cells to regenerate damaged nervous system tissue
- Advanced imaging techniques: Improving diagnosis and monitoring of MS progression
- Gut microbiome research: Investigating the role of intestinal bacteria in MS development and progression
- Novel drug delivery systems: Developing more targeted and efficient ways to deliver MS medications
- Lifestyle interventions: Studying the impact of diet, exercise, and stress reduction on MS outcomes
These research efforts offer hope for improved treatments and potentially a cure for multiple sclerosis in the future. As our understanding of the disease continues to grow, so too does the potential for more effective management strategies and interventions.
Supporting Those with Multiple Sclerosis: The Role of Caregivers and Society
The impact of multiple sclerosis extends beyond the individual diagnosed with the condition. Family members, friends, and caregivers play a crucial role in supporting those living with MS. Additionally, societal awareness and support are essential for creating an inclusive environment that accommodates the needs of individuals with MS.
How Can We Better Support People with MS?
- Education and awareness: Promoting public understanding of MS to reduce stigma and misconceptions
- Workplace accommodations: Implementing flexible policies and adaptive technologies to support employees with MS
- Accessibility improvements: Ensuring public spaces and transportation are accessible to those with mobility challenges
- Caregiver support: Providing resources and respite care for those caring for individuals with MS
- Research funding: Supporting ongoing scientific efforts to improve MS treatment and find a cure
- Policy advocacy: Working towards healthcare policies that ensure access to necessary treatments and services
- Community programs: Developing inclusive recreational and social activities for people with MS
By fostering a supportive and understanding community, we can significantly improve the quality of life for individuals living with multiple sclerosis and their loved ones. This collective effort is essential in addressing the challenges posed by MS and working towards a future where the impact of this condition is minimized.
Multiple sclerosis – NHS
Multiple sclerosis (MS) is a condition that can affect the brain and spinal cord, causing a wide range of potential symptoms, including problems with vision, arm or leg movement, sensation or balance.
It’s a lifelong condition that can sometimes cause serious disability, although it can occasionally be mild.
In many cases, it’s possible to treat symptoms. Average life expectancy is slightly reduced for people with MS.
It’s most commonly diagnosed in people in their 20s, 30s and 40s although it can develop at any age. It’s about 2 to 3 times more common in women than men.
MS is one of the most common causes of disability in younger adults.
Symptoms of multiple sclerosis
The symptoms of MS vary widely from person to person and can affect any part of the body.
The main symptoms include:
- fatigue
- difficulty walking
- vision problems, such as blurred vision
- problems controlling the bladder
- numbness or tingling in different parts of the body
- muscle stiffness and spasms
- problems with balance and co-ordination
- problems with thinking, learning and planning
Depending on the type of MS you have, your symptoms may come and go in phases or get steadily worse over time (progress).
Getting medical advice
See a GP if you’re worried you might have signs of MS.
The symptoms often have many other causes, so they’re not necessarily a sign of MS.
Let the GP know about the specific pattern of symptoms you’re experiencing.
If they think you could have MS, you’ll be referred to a specialist in conditions of the nervous system (a neurologist), who may suggest tests such as an MRI scan to check for features of MS.

Types of multiple sclerosis
MS starts in 1 of 2 general ways: with individual relapses (attacks or exacerbations) or with gradual progression.
Relapsing remitting MS
Between 8 and 9 of every 10 people with MS are diagnosed with the relapsing remitting type.
Someone with relapsing remitting MS will have episodes of new or worsening symptoms, known as relapses.
These typically worsen over a few days, last for days to weeks to months, then slowly improve over a similar time period.
Relapses often occur without warning, but are sometimes associated with a period of illness or stress.
The symptoms of a relapse may disappear altogether, with or without treatment, although some symptoms often persist, with repeated attacks happening over several years.
Periods between attacks are known as periods of remission. These can last for years at a time.
After many years (usually decades), many, but not all, people with relapsing remitting MS go on to develop secondary progressive MS.
In this type of MS, symptoms gradually worsen over time without obvious attacks. Some people continue to have infrequent relapses during this stage.
About two-thirds of people with relapsing remitting MS will develop secondary progressive MS.
Primary progressive MS
Between 1 and 2 in every 10 people with the condition start their MS with a gradual worsening of symptoms.
In primary progressive MS, symptoms gradually worsen and accumulate over several years, and there are no periods of remission, though people often have periods where their condition appears to stabilise.
What causes multiple sclerosis?
MS is an autoimmune condition. This is when something goes wrong with the immune system and it mistakenly attacks a healthy part of the body – in this case, the brain or spinal cord of the nervous system.
In MS, the immune system attacks the layer that surrounds and protects the nerves called the myelin sheath.
This damages and scars the sheath, and potentially the underlying nerves, meaning that messages travelling along the nerves become slowed or disrupted.
Exactly what causes the immune system to act in this way is unclear, but most experts think a combination of genetic and environmental factors is involved.
Treatments for multiple sclerosis
There’s currently no cure for MS, but a number of treatments can help control the condition and ease symptoms.
The treatment you need will depend on the specific symptoms and difficulties you have.
It may include:
- treating relapses with short courses of steroid medicine to speed up recovery
- specific treatments for individual MS symptoms
- treatment to reduce the number of relapses using medicines called disease-modifying therapies
Disease-modifying therapies may also help to slow or reduce the overall worsening of disability in people with a type of MS called relapsing remitting MS, and in some people with types called primary and secondary progressive MS, who have relapses.
Unfortunately, there’s currently no treatment that can slow the progress of inactive progressive MS, with no relapses or MRI activity.
Many therapies aiming to treat progressive MS are currently being researched.

Outlook
MS can be a challenging condition to live with, but new treatments over the past 20 years have considerably improved the quality of life of people with the condition.
MS itself is rarely fatal, but complications may arise from severe MS, such as chest or bladder infections, or swallowing difficulties.
The average life expectancy for people with MS is around 5 to 10 years lower than average, and this gap appears to be getting smaller all the time.
Charities and support groups for multiple sclerosis
There are 2 main MS charities in the UK:
- MS Society
- MS Trust
These organisations offer useful advice, publications, news items about ongoing research, blogs and chatrooms.
They can be very useful if you, or someone you know, has just been diagnosed with MS.
There’s also the shift.ms website, an online community for younger people affected by MS.

Multiple sclerosis – Causes – NHS
Multiple sclerosis is caused by your immune system mistakenly attacking the brain and nerves. It’s not clear why this happens but it may be a combination of genetic and environmental factors.
What happens in multiple sclerosis
MS is an autoimmune condition, which means your immune system mistakes part of your body for a foreign substance and attacks it.
In the case of MS, it attacks the myelin sheath in the brain and spinal cord.
This is the layer that surrounds your nerves, protecting them and helping electrical signals travel from the brain to the rest of the body.
The attacks cause the myelin sheath to become inflamed in small patches (plaques or lesions), which can be seen on an MRI scan.
These patches of inflammation can disrupt the messages travelling along the nerves.
It can slow them down, jumble them, send them the wrong way, or stop them getting through completely.
This disruption leads to the symptoms and signs of MS.
When the inflammation goes away, it can leave behind scarring of the myelin sheath (sclerosis).
These attacks, particularly if frequent and repeated, can eventually lead to permanent damage to the underlying nerves.
Causes of multiple sclerosis
It’s not clear what causes the immune system to attack the myelin sheath.
It seems likely that it’s partly caused by genes you inherit from your parents and partly by outside factors that may trigger the condition.
Some of the factors that have been suggested as possible causes of MS include:
- your genes – MS isn’t directly inherited, but people who are related to someone with the condition are more likely to develop it; the chance of a sibling or child of someone with MS also developing it is estimated to be around 2 to 3 in 100
- lack of sunlight and vitamin D – MS is more common in countries far from the equator, which could mean that a lack of sunlight and low vitamin D levels may play a role in the condition, although it’s not clear whether vitamin D supplements can help prevent MS
- smoking – people who smoke are about twice as likely to develop MS compared with those who don’t smoke
- teenage obesity – people who were obese during their teenage years have an increased risk of developing MS
- viral infections – it’s been suggested that infections, particularly those caused by the Epstein-Barr virus (responsible for glandular fever), might trigger the immune system, leading to MS in some people
- being female – women are 2 to 3 times more likely to develop MS than men; the reason for this is unclear
Further research is needed to understand more about why MS occurs and whether anything can be done to prevent it.

Primary progressive type of multiple sclerosis | ICRC
The first question is how many patients suffer from this type of course? Not so much: 10-15% of the total number of MS patients.
At what age does it usually start? While the relapsing-remitting type most often begins at age 30, PPMS usually affects people around the age of 40. In addition, men and women suffer from primary progressive multiple sclerosis equally, in contrast to relapsing-remitting, where women are more likely to get sick.
Is there a genetic predisposition? Let’s just say no. There is no clear, proven genetic predisposition. In patients with PPMS, as well as in all other patients with MS, there is a genetically determined risk factor — the presence of the HLA-DR2 haplotype (HLA-DRB1*1501 on chromosome 6). Scientists have tested a large number of different haplotypes (I remind you that a haplotype is a combination of genes that is transmitted unchanged from parents to children), but did not confirm the relationship between any combination of genes and the occurrence of PPMS, and could not find genetic factors that determine the rate of increase in the disease. Let me also remind you that a genetic risk factor and a genetic disease are two different things: a genetic risk factor is a combination of normal genes (haplotype) proven in a large number of patients, the presence of which increases the risk of developing MS. Therefore, the presence of a certain haplotype is necessary, but not sufficient for the development of MS – a combination of many other risk factors is also needed. A genetic disease is the presence of an incorrect, abnormal, damaged, or, scientifically speaking, mutated gene, which is responsible for the development of a genetic disease. Therefore, the presence of a mutation is necessary and sufficient for the development of a genetic disease. We tried to simplify the answer to the constant question of patients: “is multiple sclerosis inherited? Is it a genetic disease?
The main features of primary progressive multiple sclerosis are the absence of exacerbations and the steady increase in symptoms. However, this increase can be quite slow, because about a quarter of patients after 25 years of the disease continue to move independently, without support. Also, a quarter of patients need support (unilateral support) already 7 years after the onset of the disease. This data is for patients who did not receive any treatment.
However, if no specific features of PPMS were found at the level of risk factors compared to relapsing-remitting MS, then studies of pathological changes in the substance of the central nervous system and the picture on magnetic resonance imaging corresponding to these pathological changes made it possible to confirm a significant difference between PPMS and relapsing-remitting multiple sclerosis, so to speak, to substantiate the long-known features of the clinical picture of the disease (see Fig. ).
In the brain of patients with PPMS, there are significantly fewer foci of demyelination (plaques) compared to patients with other types of MS. Indeed, the appearance of a new plaque indicates an active process of inflammation, affecting primarily myelin (the sheath of the nerve fiber – the process of the neuron, the axon). This is characteristic of relapsing-remitting MS, while in PPMS the damage is non-localized, “less focal”, more widespread, diffuse, active plaques rarely (or not at all). Damage to axons (outgrowths of nerve cells) and a non-focal process of demyelination spreads both in the cerebral cortex and in the white matter, as well as in the spinal cord. In addition, the blood-brain barrier suffers: it becomes permeable in all parts of the brain in patients with PPMS, while in remitting permeability occurs mainly in the foci. If we look at the immunological markers of inflammation, then in PPMS their concentration is significantly lower than in patients with remitting MS. Which indicates a less inflammatory nature of changes in the central nervous system.
MRI findings in patients with PPMS confirm the above features. First, active, contrast-mediated demyelination foci are rarely detected (which is typical in relapsing-remitting MS). The brain appears not to be significantly damaged, with few lesions, but the use of certain imaging modes (DWI) reveals marked changes in the gray matter of a seemingly normal-looking brain. Moreover, the degree of changes in the DWI regimen corresponds to the severity of movement disorders, which will appear in a person only two years after the examination.
Secondly, in patients with PPMS, signs of atrophy (reduction in volume) of the gray and white matter of the brain and spinal cord are noted much earlier, almost from the first year of the disease.
Thirdly, with another type of MR study – MR spectroscopy, changes are determined that are characteristic of an increase in the number of astrocytes. Astrocytes are cells of the brain and spinal cord that have a supporting, nourishing effect on neurons (axons dressed in myelin sheath depart from neurons). So, with the decay of neurons, astrocytes begin to increase quantitatively, which is denoted by the term astrocytosis.
Fourth, PPMS is again characterized by diffuse, widespread damage to the spinal cord. Not focal, as in relapsing-remitting MS or as in neurooptic myelitis, but diffuse. Moreover, the degree of spinal cord atrophy has a strong correlation between the severity of disorders (the number of points on the EDSS scale, the degree of disability) in a person. And if atrophy of the brain to one degree or another takes place in a relapsing type of course, then such a pronounced atrophy of the spinal cord is characteristic exclusively for PPMS.
Thus, in the primary progressive type of the course of multiple sclerosis, in contrast to the relapsing type, damage to the central nervous system is diffuse, widespread, the main damage affects primarily axons – processes of nerve cells (the process of neurodegeneration), and not their sheaths – myelin (the process of demyelination), which leads to atrophy of the brain and spinal cord and the constant accumulation of disorders (symptoms) of the nervous system – the accumulation of disability.
What are the symptoms of PPMS?
Before describing the manifestations, symptoms, it should be noted that there are no exacerbations in the primary progressive type of multiple sclerosis. From the very beginning, the symptoms do not improve, do not go away, the disturbances gradually increase. There may be slight fluctuations in their severity, but there is no talk of any remission.
The main manifestation of PPMS is the lower spastic paraparesis. Let’s break this term down. “Lower” means the lower limbs, i.e. changes occur mainly in the legs. “Paresis” – weakness of the limb, “pair” – either upper or lower limbs at the same time, so “lower paraparesis” means weakness of the lower limbs. “Spastic” – in addition to weakness, an increase in tone occurs in the legs. The muscles become tense, and the movements in the legs become limited, not only because of weakness, but also because of the need to overcome the high muscle tone that interferes with the implementation of voluntary movements. However, spasticity is not only an increase in muscle tone. Painful muscle spasms, which are sometimes more pronounced than the actual increase in tone, are also referred to as spasticity. A separate symptom of PPMS is an increase in weakness during movement: the further the patient goes, the more tired he is. Those. weakness begins to increase in the process of movement. Such fatigue has its own mechanism of development and is associated not only with the presence of lower paraparesis. Frequent manifestations of PPMS include urinary disorders: usually a strong urge to urinate, as well as urges at night.
Thus, the main manifestations of PPMS are weakness of the lower extremities and their spasticity (increased tone and pain spasms), increasing fatigue during movement (walking) and frequent urination (urgency). These symptoms are present in 80% of patients.
In 15% of patients, a violation of coordination, the so-called atactic syndrome, is detected. When it occurs, the patient experiences difficulty in performing targeted movements due to their mismatch. Movements become redundant, inaccurate, a person misses the object that he wants to take. In addition, stability disorders may occur, when it is difficult for the patient to maintain balance in a standing position, he begins to swing to the sides, sometimes there is a kind of trembling of the legs and torso.
How is PPMS diagnosed?
The diagnosis of PPMS should be based, as with any other type of course, on a body of data. The main, obligatory sign of a progressive and primary type of course is the presence of an increase in neurological disorders for a year or more. Any two of the following must be added to this main feature:
- the presence of nine or more lesions on MRI of the brain or the presence of 4 or more lesions on MRI of the brain and changes in visual evoked potentials
- presence of two or more lesions in the spinal cord
- oligoclonal type of IgG synthesis in cerebrospinal fluid (CSF)
We obtain cerebrospinal fluid during a lumbar puncture. Currently, this is a mandatory procedure for suspected multiple sclerosis, and especially for the primary progressive type of its course.
In addition, before setting up PPMS, we need to conduct a wide examination to rule out a number of diseases that are clinically similar to this type of MS course. These include a tumor of the spinal cord, hereditary diseases, metabolic disorders, inflammation of the central nervous system (sarcoidosis, vasculitis), neuroinfections, vascular lesions of the central nervous system, degenerative diseases. Therefore, tune in to the fact that they will take a lot of blood tests from you, and even puncture.
What is the prognosis for a patient with PPMS?
The prognosis is based on the rate of progression: the sooner the patient reaches an EDSS disability level of 3, the sooner he will reach a level of disability of 6 points (walking with a stick), and the sooner a degree of disability of 6 points occurs, the sooner the patient will be in a wheelchair . The majority of patients reach the level of 6 points 10-20 years after the onset of the disease. However, these are data without treatment. If we apply a therapy that has proven its effectiveness in clinical trials in patients with a primary progressive type of multiple sclerosis, then all these prognostic periods increase by a third. More on this in the section on anti-B cell therapy and more specifically in the article on ocrelizumab, an approved drug for the treatment of PPMS.
Does it only happen to the elderly? Is it true that there is no cure? Important questions about multiple sclerosis – Meduza

Every year on the last Wednesday of May, World Multiple Sclerosis Day is celebrated. To draw attention to this disease, a musical flash mob was held in Moscow in mid-May. Together with the organizers of the action – the Moscow Society of Multiple Sclerosis and the Roche company – we answer important questions about this disease: what is multiple sclerosis, how is it diagnosed and is it possible to fully recover.
What kind of illness is this? Is it somehow related to age and forgetfulness?
Multiple sclerosis (MS) is not related to senile dementia and can start at any age. Briefly, its mechanism can be described as follows. The disease affects the central nervous system, which is based on nerve cells, neurons. They exchange electrical signals with each other and with other parts of the body using long processes. Thanks to this exchange, we can think, speak, move and digest food. Each nerve process is “wrapped” in myelin – a sheath of proteins and lipids. Myelin works like an insulator at the wire – it protects the nerve processes and facilitates the exchange of information between nerve cells and the body. In multiple sclerosis, the myelin begins to break down, causing damage to the “insulation” of the nerves. Because of this, the speed at which the body and brain exchange signals decreases – and in some cases the signals are blocked altogether.
Most cases of MS occur in young people between the ages of 20 and 30—that is, it occurs at an active age, when they usually get higher education, create families and build a career. And in 5% of cases, patients are children at all.
When multiple sclerosis is just beginning to develop, there may be no symptoms. But when myelin is destroyed a lot, a person begins to see and speak worse. Problems arise with thinking, learning and planning – they gradually weaken, and in the end the disease can cause disability.

Why do people get MS?
Doctors and scientists still do not know exactly why multiple sclerosis occurs. It is believed that the disease develops due to errors in the immune system: instead of attacking harmful microbes, the immune system destroys the cells responsible for the synthesis of myelin. Because of this, multiple sclerosis is called an autoimmune disease.
Studying risk factors, doctors concluded that the place of birth seems to play an important role (it is believed that the risk of developing multiple sclerosis increases from south to north) and genetic characteristics of a person. In addition, smoking and obesity in children and adolescents may increase the risk of MS.
How do you know if someone has multiple sclerosis?
There is no single test that can unequivocally show that a person has started MS. To make a diagnosis, a doctor will have to take a person’s medical history, examine them, order a neurological examination and magnetic resonance imaging (MRI) of the brain, and conduct behavioral tests.
Multiple sclerosis has symptoms, and of course, you should pay attention to them. But the same problems can occur with other diseases (or even due to overwork). In any case, if you notice something similar, you should consult a doctor.
The symptoms of MS depend on where in the brain the myelin destruction has begun, and therefore may differ from person to person. Most often, MS affects the nerve fibers responsible for vision and movement.
Movement problems in MS :
- numbness or weakness in an arm or leg, or both arm and leg, and on one side of the body electric shock “, which runs along the spine from head to toe (Lermitte’s symptom)
- hand shaking, uncoordinated, unsteady gait

Visual problems in MS :
- partial or complete loss of vision, most often in one eye. Moving your eyes can be painful
- Double vision
- Blurry vision
In addition, slurred speech and dizziness can occur with MS. Some patients complain of fatigue, tingling or pain in different parts of the body, sexual dysfunction, bowel or bladder problems.
Understanding that a person is developing MS can also be difficult because the disease manifests differently at different stages. Doctors have to focus not so much on the results of tests and studies, but on the human condition. And often the doctor needs time to make an accurate diagnosis. In 85-90% of cases, MS begins as relapsing-remitting (RRS), which is when symptom exacerbations (relapses) are followed by periods of improvement (remissions). And only after 10–20 years can the next stage begin – secondary progressive MS (SPMS). In this case, the symptoms during the attacks gradually become more severe. Or there may be no periods of improvement at all – the patient just gets worse and worse.
But in about 10% of patients, the disease immediately manifests itself in a more severe form, then it is called primary progressive MS (PPMS). It is believed that in Russia there are 5–6% of such patients. PPMS occurs later in life (around age 40) but can progress almost twice as fast as relapsing-remitting multiple sclerosis. And with this type of illness, a person’s condition is steadily deteriorating from the very beginning, there are no periods of improvement. A common symptom of PPMS is difficulty walking, which gradually gets worse. It is easy to confuse these symptoms with difficulties with movement, which people in their 40s and 50s often have for other reasons. Therefore, it may also take some time to make an accurate diagnosis.

They say there is no cure for multiple sclerosis. This is true?
Indeed, there is currently no cure for multiple sclerosis. But there are drugs that help slow down the progression of the disease and control the symptoms. They must be prescribed by a doctor.
If the disease proceeds with exacerbations and develops relatively slowly, the doctor focuses on alleviating the patient’s condition. For example, to cope with a relapse, steroid drugs are used to reduce inflammation, relieve swelling, and generally improve the quality of life. Also, with relapsing-remitting multiple sclerosis, the patient may be prescribed drugs that affect the probable cause of the disease – immune cells. Relapsing-remitting MS can proceed in very different ways – from an extremely mild variant to an aggressive one. Therefore, sometimes immune-suppressing drugs are not needed in principle – if the disease develops slowly, they will do more harm than good. In other cases, the doctor may prescribe such drugs. For example, interferons, drugs that can regulate immunity and make immune cells a little less aggressive.
If a person develops primary progressive multiple sclerosis, then treatment is immediately aimed at reducing the risk of developing disability. To do this, the patient requires anti-B-cell therapy, which affects certain immune cells – it affects mature B-lymphocytes and thus suppresses the immune system. This treatment is expensive (like any therapy designed to slow the progression of MS) and is not included in the 12 High Cost Nosologies program (so it may not be easy to get it for free).

Need MS Rehab?
Rehabilitation is an essential component of comprehensive care for people with MS. Its goal is to improve and maintain a variety of functions: the ability to speak, walk, work. Moreover, rehabilitation is useful for people with both PPMS and RMS.
The benefits of exercise for people with MS were first proven in 1996. It turned out that patients who engaged in aerobic exercise improved their cardiovascular system and muscle strength, they suffered less from fatigue and depression, and more often participated in social activities. According to Canadian recommendations, twice a week it is useful to do aerobic exercises for half an hour and a couple of times to do strength exercises for the main muscle groups. You can also do this at home. But today it is believed that complex rehabilitation works best, which is organized by a medical team of a physical therapist, a rehabilitation therapist and a neuropsychologist, and, if necessary, a speech therapist. Compared to patients who were not offered rehabilitation, participants in rehabilitation programs improved their ability to self-care, well-being, and quality of life. Therefore, it makes sense to carefully choose a rehabilitation center.
Can a special diet slow down the development of MS?
There is no such diet. However, a balanced healthy diet is very important because it helps prevent cardiovascular disease and manage other problems such as constipation. Experts recommend that people with MS eat a diet that is low in fat and salt but high in fiber.
Vitamins and dietary supplements will not help with MS. And even more than that: it seems that they do more harm than good. The only exception is vitamin D.
