The appearance of the person of signs of this disease requires immediate hospitalization and intensive treatment in hospital, sometimes in the neurosurgical Department. The probability of death is 20%.

The causes of the disease

At the core of Wernicke encephalopathy is a violation of the absorption of thiamine from food. The lack of vitamin B1 impaired utilization of glucose by neurons, appear and accumulate toxic products of metabolism, there is demyelination (destruction of myelin – the substance covering the nerve fibres and is responsible for the transmission of nerve impulses). Critical deficiencies of B1 can lead to:

  • chronic alcoholic intoxication (most common cause);
  • diseases of the digestive system;
  • uncontrollable vomiting in pregnant women or in case of poisoning with some drugs;

Observed somatic abnormalities – severe fever up to 41ºC, bad decreasing drugs, hemorrhages in the skin, are easily formed bedsores. Encephalopathy gayet-Wernicke accompanied by disturbances of breathing and heartbeat, decrease in blood pressure. All exacerbated by comorbidities. According to various sources, the mortality rate reaches 20 – 50%.

Treatment and prognosis

For installation and confirmation of the diagnosis requires consultation neurologist and psychiatrist.

Occasion therapy of comorbidities.
