Dizziness – the causes of occurrence, in which diseases it occurs, diagnosis and methods of treatment.

Every person during his life at least once experienced dizziness – a condition in which it seems that the body and / or the environment are rotating, there is a feeling of instability, balance is lost, orientation in space is disturbed.

A single dizziness is not a cause for concern, but if the attacks are repeated regularly, and also become prolonged, accompanied by other symptoms (nausea, vomiting, heart palpitations, etc.) – this is a reason to see a doctor.

It is very important to identify the cause of dizziness in a timely manner, because, firstly, it can be a symptom of serious diseases, and secondly, dizziness is dangerous in itself, because it can lead to injuries.

Varieties of dizziness

It is customary to distinguish between the following types of dizziness:

– proprioceptive – with a sense of movement (rotation) of the body in space;

– tactile – with a sense of movement, swing, instability of the support under the feet;

– visual – with a sense of the movement of the environment around you.

Dizziness is also divided into central and peripheral. Peripheral dizziness begins acutely: a person cannot stand without support, is forced to sit down or even lie down. In this case, as a rule, there are nausea, vomiting, excessive sweating, heart palpitations, tinnitus. Central vertigo is less pronounced, but differs in duration. With this type of dizziness, such neurological symptoms as blurred vision, impaired tactile and pain sensitivity, and coordination are observed.

Possible causes of dizziness

Dizziness can occur for a variety of reasons, including in completely healthy people: for example, under stress, as a result of poor nutrition, frequent smoking and alcohol intoxication, impaired focusing of vision, fast non-linear movement (for example, on a carousel), etc. .

Dizziness can be caused by medication,

including antibiotics, diuretics, non-steroidal anti-inflammatory drugs (diclofenac, ibuprofen, etc.), anticancer drugs (used for chemotherapy), angiotensin-converting enzyme inhibitors (enalapril, fosinopril), antidepressants, antimalarial drugs, calcium channel blockers (nifedipine, etc. ) and etc.

To find out the exact cause of dizziness, you need to consult a doctor who will conduct an initial examination and prescribe methods for further diagnosis. It should be remembered that

dizziness can be a symptom of a dozen different diseases, the diagnosis of which requires various studies.

What diseases cause dizziness

Diseases of the inner ear

Intense rotational vertigo is a typical symptom of diseases of the inner ear (an organ that is responsible not only for hearing, but also for balance),

such as:

– benign paroxysmal positional vertigo (BPPV). The cause of this pathology is the displacement of otoliths – the smallest crystals located on the surface of the cells of the inner ear, and a change in the normal hydromechanics of the fluids of the inner ear. BPPV is manifested by sudden, short-term, severe dizziness when changing body position, sometimes accompanied by nausea and vomiting;

– Meniere’s disease. A disease in which there is an increase in the volume of fluid in the inner ear and an increase in pressure in it. The patient has recurrent attacks of progressive deafness (usually unilateral), tinnitus and dizziness. The causes of this disease are not completely clear, but they can be associated with vascular pathologies, the consequences of injuries (head, ear), inflammatory and infectious diseases of the inner ear.

Dizziness can be caused by inflammation (labyrinthitis) and trauma (acoustic, mechanical, barotrauma) of the inner ear.

Diseases of the vessels of the brain (cerebrovascular diseases)

Dizziness can be associated with pathologies in which the blood supply to the brain is disturbed:

– atherosclerosis of cerebral vessels (cerebral atherosclerosis) is a serious disease accompanied by the formation of atherosclerotic plaques in the vessels of the brain and leading to impaired cerebral circulation. In the early stages, it manifests itself with symptoms such as dizziness, fatigue, irritability, difficulty concentrating;

– chronic cerebral ischemia – a disease characterized by a progressive deterioration in the blood supply to the brain. A person suffers from dizziness, headaches, impaired coordination, memory worsens, and the general psychological state.

Volumetric intracranial masses

Dizziness may be associated with neoplasms (for example, acoustic neuroma, etc.), inflammatory lesions of the cerebellum, etc.

Cardiovascular diseases

Dizziness can occur with various cardiovascular pathologies: cardiac arrhythmias (arrhythmias, tachycardia, bradycardia), arterial hypo- or hypertension, heart failure, etc.

Degenerative-dystrophic changes in the cervical spine

Dizziness is often found in patients with problems of the cervical spine, such as osteochondrosis, protrusions and herniated discs, uncovertebral arthrosis of the cervical spine. Dizziness occurs due to difficulty in the flow of blood to the brain due to compression of the vertebral arteries.

Also, dizziness can be caused by neurological and mental diseases, such as Parkinson’s disease, migraine, Alzheimer’s disease, a number of infectious diseases, anemia (a decrease in hemoglobin levels in the blood).

Which doctors should I contact?

When dizziness occurs, you should first of all contact a therapist (children – a pediatrician), who will determine which specialist to refer to next. If the possible cause of dizziness is associated with diseases of the cardiovascular system, you will need to consult a cardiologist. If the symptoms indicate a pathology of the inner ear – a neurologist and an otolaryngologist. With neurosis, anxiety, the patient will be referred to a psychotherapist, neurologist.

Diagnostics and examinations

To accurately diagnose cerebrovascular diseases leading to dizziness, ultrasound examination of the vessels of the brain allows,

In cardiovascular diseases, electrocardiography (ECG), echocardiography (EchoCG), 24-hour Holter ECG monitoring, and keeping a blood pressure diary will help to identify the cause of dizziness.

Treatment

Since dizziness is not an independent disease, but a symptom of various pathologies, treatment is prescribed depending on the underlying disease.

What to do if you feel dizzy

If you regularly experience dizziness, you should see your doctor.

You should also know what safety precautions you need to take during an attack of dizziness. First, stay calm. Get into a position where you feel stable. It is best to lie down so that the head and shoulders are at the same level. Loosen clothing that restricts movement. Reduce bright lights and loud noises. If possible, measure blood pressure, monitor the pulse rate, the presence of arrhythmias. If dizziness is accompanied by an increase in blood pressure, fever, severe weakness, sweating, heart rhythm disturbances, visual impairment, speech impairment, movement coordination – immediately call an ambulance!

IMPORTANT!

The information in this section should not be used for self-diagnosis or self-treatment. In case of pain or other exacerbation of the disease, only the attending physician should prescribe diagnostic tests. For diagnosis and proper treatment, you should contact your doctor.
For a correct assessment of the results of your analyzes over time, it is preferable to do studies in the same laboratory, since different laboratories may use different research methods and units of measurement to perform the same analyzes.

Dizziness: causes, symptoms and treatment, what to do about it

Dizziness is common and can occur at any age. Often people live with dizziness for more than one month and do not go to the doctor, believing that this is a temporary phenomenon, it will go away on its own, and so on. But now you can get rid of this unpleasant feeling. Together with the neurologist of the Pirogov Clinic, Pavel Vyacheslavovich Smirnov, we understand the types of dizziness and related diseases, as well as popular misconceptions.

What are dizziness

What is dizziness? Usually we mean such symptoms as staggering, general weakness, darkening of the eyes. Since most often it is problematic for a person to describe his feelings, diagnosis can be a difficult task. However, determining the type of dizziness is the most important thing.

Physicians classify dizziness into systemic and non-systemic .

Systemic dizziness is similar to the sensations that occur after riding a carousel: the ground is creeping out from under your feet, there is no focusing of your eyes, objects are floating from side to side. Such dizziness can be accompanied by nausea and even vomiting, an increase in blood pressure.

And non-systemic dizziness is called just the symptoms that we have already talked about: instability when walking, weakness, darkening in the eyes, fainting.

Systemic vertigo is a specific disease.

1) Benign paroxysmal positional vertigo (BPPV) – up to 50-60% of cases.

BPPV manifests itself when turning the head, most often in a horizontal position, when turning from one side to another. It proceeds paroxysmal: a change in the position of the head or torso provokes dizziness, which usually lasts up to 30 seconds. Then it fades and does not bother if you do not move, but at the next turn the attack will repeat. As a rule, patients with BPPV feel much better if they are in an upright position.

2) Meniere’s disease – 15-20% of cases.

Vertigo is accompanied by noise in the ear or in the head on one side. The head is spinning strongly, there may be nausea or vomiting. Noise is heard necessarily in one ear (then noise from both sides may join), when dizziness begins, and when it stops, the noise subsides. The attack usually lasts 3-5 days.

3) Vestibular migraine – 5-8% of cases.

This is a relatively rare diagnosis, which is manifested by an attack of systemic dizziness (maybe nausea) lasting 5-30 minutes and followed by the development of a headache. This is almost a mandatory symptom for making such a diagnosis.

4) Vestibular neuronitis – 5-8% of cases.

The disease resembles Meniere’s disease, but there is no noise in the ears or head. Symptoms: dizziness with nausea, vomiting, regardless of body position. Within 2 months, you may experience unsteadiness when walking. The duration of the attack is 5-7 days, exacerbation – no more than two times. If an exacerbation occurs more often, this means that the diagnosis is different.

5) Group of rare types of dizziness – no more than 5% of cases.

Where do non-systemic dizziness come from?

And again, the blame for everything (up to 80% of cases) is stress and depression. In such cases, dizziness “coexists” with increased anxiety or apathy, sleep disturbances.

In other cases, non-systemic dizziness causes:

– low blood pressure,

– an increase or decrease in sugar levels,

– lowering the level of hemoglobin in the blood,

– large atherosclerotic plaques in the vessels of the neck,

– heart disease, leading to a decrease in blood pressure,

– Focal brain damage and other pathologies.

Once there was an opinion that cervical osteochondrosis causes dizziness. However, it has now been scientifically proven that such dizziness almost never occurs, only as a rare exception. For the so-called cervical dizziness to occur, a lot of factors must converge, and even then they will most likely lead to an ischemic stroke.
