Why the scalp dies

Contents:

Some people face such a problem as numbness of the head. What is the reason for this condition? Is it an alarming symptom of serious diseases and how to deal with it?

Causes of numbness of head

Why does the back of the head, crown or forehead become numb? There are several main reasons:

1. Vessel contraction during sleep or prolonged bed rest.
2. Psychological stress.
3. Blood circulation problems. Anemia.
4. Infringement of an innervation: a neuropathy at a multiple sclerosis, a disadvantage of vitamins.
5. Endocrine diseases.
6. Autoimmune pathology of vessels( vasculitis).
7. Dystrophy on the background of serious illnesses or a meager diet.
8. Injuries.
9. Subcooling.
10. Osteochondrosis.
11. Infections, common cold.

Vascular depression

When the scalp becomes numb, the cause may be fatigue, compression of its vessels during sleep, long lying of the patient in a coma. When squeezing, there is a violation of soft tissue trophism, as well as nerve endings, suitable for them. As a result, sensitive receptors do not feel pressure, pain.

Excitement, anger, fear

Stress is one of the culprits of paresthesias - the sensation of needles and a decrease in sensitivity at the same time. The fact is that psychological stress leads to a sharp reduction in the vessels of the skin, which leads to the dullness of the occipital part of the head, the crown of the head, and also its left and right parts. In this case, the nerve endings experience oxygen starvation due to ischemia.

In addition, with a long hours of stress, the muscle helmet of the head is strained, which contributes to the violation of blood circulation.

Blood supply disorder

With reduced blood flow to the scalp, the left or right parts become dumb, what are these symptoms? In what cases is it possible:

1. Atherosclerotic lesions of the arteries.
2. Loss of blood( possibly with donation, delivery of tests).
3. Propensity to thrombi( especially when taking oral contraceptives).
4. Rheumatic vascular disease.
5. Osteochondrosis.
6. Subcooling.
7. Cardiovascular pathology.

In atherosclerosis, the flow of blood is disturbed, as the lumen of the arteries is clogged with cholesterol plaques. The loss of blood can also cause a dying left or right side of the head.

Thrombosis of small capillaries during the administration of oral contraceptives and other blood thickening agents leads to microcirculation disorders in the skin. Rheumatic vascular pathology( lupus erythematosus, immunocomplex diseases of capillaries) can cause numbness due to deterioration of nerve tissue supply.

Osteochondrosis is one of the causes of numbness of the occipital part of the head, to which sensitive spinal nerves come from the cervical plexus. It can be hampered by a hernia of the spine or bone outgrowths - osteophytes. Pain, inflammation cause muscle tension, which also squeezes the spinal nerves, innervating the skin of the occiput.

Cardiovascular diseases, especially neurocirculatory dystonia, can cause disturbances in both blood supply and innervation of the head.

Anemia

This is a shift in which the amount of red blood cells in the peripheral blood decreases. There is anemia with a deficiency of vitamin B12, B9, iron, protein and other nutrients. Possible with pathologies in the structure of hemoglobin, immune reactions of the body to its own red blood cells with a viral infection. Anemia leads to numbness of the scalp, as the nerve endings do not get the oxygen necessary for life.

Neuropathies and neuralgias

Nerve diseases are the most likely cause of numbness in the scalp. Among the main diseases of the peripheral nervous system are:

1. Neuropathies of various origins: diabetic, against the background of deficiency of B vitamins and various minerals.
2. Multiple Sclerosis.
3. Neuralgia.

Neuropathies are a common cause of numbness in the head. Occur during shear in metabolic processes, such as diabetes mellitus. If a violation of the sensitivity of the skin of the face and head is combined with such symptoms as thirst, excessive urination, the likely cause is a lack of insulin or a decrease in response to it.

Multiple sclerosis is a disease of the nervous system, in which the insulating material of the nerves is damaged - the myelin sheath. The reason is a malfunction in the functioning of the immune system, which begins to attack its own pathways. Numbness of the head at the same time is combined with muscle weakness, a violation of the sensitivity of other parts of the body.

Neuralgia is a consequence of the inflammatory process along the nerve path. It can occur with colds, herpes infection.

Hypothermia

One of the factors that cause sensitivity disorder, hypothermia is the head. Subcooling is one of the factors that break blood circulation and innervation simultaneously. The effect of low temperatures leads to a narrowing of the vessels and a violation of soft tissue trophism.

After a cold exposure, inflammation of the nerves is possible. Immediately, the effect of cold leads to a strong spasm of the arteries of the head, which disrupts the nutrition of soft tissues and the nerve endings in them.

Diagnostics

With the ever-recurring symptom of numbness need to address to the neurologist, to pass comprehensive studies:

1. brain ultrasound, the perfect option - MRI.
2. Rheoencephalography will assess the state of vessels of different diameters.
3. General blood test, urine if necessary.
4. Biochemistry blood glycated hemoglobin in suspected diabetes.

Treatment numbness

head Reduced sensitivity of the scalp requires treatment of the underlying pathology that led to the appearance of this symptom:

1. For the treatment of neuritis, degenerative disc disease, multiple sclerosis shows an electric or phonophoresis with vitamin B1, ligase, biological stimulants. Useful injections of vitamins B1, B6 and B12.
2. Diabetic neuropathy is treated with hypoglycemic agents. Metabolic drugs are also used: Lipoic acid, Actovegin.
3. When osteochondrosis useful massage.

Numbness of the head is an occasion to consult a doctor. The symptom develops with pathological processes of the vascular and nervous systems. To treat a numbness independently without preliminary consultation of the neuropathologist it is impossible.
