The causes of numbness of the head are not always associated with any illness. Hyperesthesia of the head and any other parts of the body is considered the norm in cases where a person does not move for a long time or is in an incompetent position.
This happens, for example, in an improperly equipped workplace or during sleep. In such situations, the blood circulation is temporarily disrupted, which leads to numbness and tingling in the muscles and skin. After changing the position of the body, hypesthesia itself takes a few minutes. You can accelerate the recovery of normal blood supply by means of a light massage. The danger is frequent numbness of the head or neck, accompanied by such clinical signs as deterioration of vision and hearing, and also temperature rise. In particular, a neurologist consultation and a comprehensive examination are urgently needed in the following symptoms:
- Motor activity disturbances;
- Dizziness, traumatic motion, general weakness;
- Involuntary emptying of the intestine or bladder;
- Unexplained language.
Concomitant symptomatology can not reliably indicate the causes of numbness of the head, therefore, an exact diagnosis is required.
Abnormalities combined with duality in sight, coordination impairment and general weakness can be caused by the following conditions and diseases: injuries; Scratching the nerves; Multiple sclerosis; Violation of blood circulation in the brain; Tumor of the brain.
Craniocerebral trauma can cause a hemorrhage in the brain tissue or its skin and require immediate hospitalization.
The most dangerous are fractures of the cheekbones, upper jaw and ophthalmic faces. In addition, as a result of a severe blow, a concussion may occur. His symptoms usually go away within a few days. If this does not happen, then more serious brain damage was lost during the diagnosis.
The problem causing numbness in the head of the head may also be localized in the cervical spine, which also suffers from skull trauma. Hyposthesia sometimes indicates clamping of the eye, maxillary, mandibular or trigeminal nerve. Compression can occur as a result of tumors, posttraumatic adhesions, enlargement of the cerebellar arteries, as well as inflammation of the nasal sinuses and oral cavity.
Neuralgia causes severe pain in the nose, eyes and ears and is often accompanied by tingling or numbness of the head and face of the face. To neurological damage is also paralysis of Bell. Despite the fact that it is thought to be a consequence of infection and inflammation of the facial nerve, the pathogenesis of paralysis has not been studied to the end. As a rule, his sudden occurrence is preceded by ear pains and loss of taste. Recovery occurs within a few months.
Favorable prognostic sign is considered paralysis and numbness of the head only from the right or left side. In multiple sclerosis, replacement of certain parts of the nerve tissue with the cells of the connective tissue occurs. There is a loss of sensitivity, visual impairment and coordination of movements. The cause of hypestesia is damage to the myelin shell in the spinolemal tract, which is responsible for transmitting signals about external stimuli (touch, temperature, pain, etc.).
Overdose of cerebral circulation is paroxysmal and most often occurs as a complication of atherosclerosis, hypertension or osteochondrosis. The focal symptoms vary depending on the location of the pathology.
The head dries only with PNMK in the system of internal carotid artery. The numbness of the head is almost always on the one side where the blood circulation is disturbed, and hypesthesia on the opposite side is rare.
Other symptoms include deep loss of sensitivity in the middle of the upper lip and tongue, sometimes - sudden blinding on one eye. Regardless of the sensitivity disorder, there is a restriction of mobility, often in combination with dysarthria or aphasia. If the focal symptoms are observed for more than a day, then such violations should be taken as a cerebral stroke.
The timely start of therapy (in the first 6-12 hours) allows you to limit the area of the lesion and restore the lost brain function. Any brain tumor as it develops causes numbness of the head due to the fact that the volume of the cranial box is limited. Growth of the tumor leads to pressure on the surrounding areas of the brain, disrupting their functioning, therefore, vision impairment, weakness and headaches can be observed.
Headache numbness may also occur for a number of other reasons, which do not directly endanger human life, but can cause pain and other unpleasant sensations. Among the provocative hypothesis of factors should be noted incorrectly performed dental procedures, shingles in the area of the face, as well as avitaminosis.
Diagnosis and treatment of diseases with numbness of the head
With regular numbness of the skin of the head and neck, an urgent consultation with the neuropathologist is urgently needed, especially if the duration of the attacks exceeds 2-3 minutes.
Diagnostics should include the following methods:
- A general blood test can detect iron deficiency anemia, as well as Addison-Birmer's disease, in which hematopoiesis is disturbed due to lack of vitamin B12;
- X-ray examination and magnetic resonance imaging determine the displacement of bones and other pathologies, which could result in nerve damage and numbness of the head;
- Electron neuromorography establishes the location of the affected nerve, as well as detects neuropathy and carpal tunnel syndrome;
- Ultrasound Doppler study diagnoses vascular disease and circulatory disorders in the sleep or vertebral-basilar arteries.
Depending on the internal and clinical picture, other studies and tests may also be required for numbness of the head.
The presence of a history of craniocerebral trauma involves consultation of a surgeon and a traumatologist.
When numb in the area of the chin after orthodontic manipulation, turn to the dentist. In case of damage to internal organs, a multidisciplinary examination is required. The choice of the method of treatment directly depends on the root causes of numbness of the head and should be made only after complex studies of the body. Complete rehabilitation sometimes occurs over a long period of time, but complete treatment is necessary to avoid various complications that can be life-threatening.
In case of hypothesis, care should be taken near the sources of heat and during meals, as due to a lack of sensitivity you can accidentally injure your mouth or burn. In addition, it is recommended to avoid situations in which head numbness often appears, as the intensity of this symptom may depend on external factors.
