Why is an electroencephalogram prescribed?
An electroencephalogram is a safe and painless research method used to assess the level of electrical activity in the brain. Brain cells use electrical impulses to communicate - this type of activity takes place even during sleep.
Electroencephalogram is a basic and important test for diagnosing various brain disorders and diseases.
The following types of pathologies can be diagnosed using this research method:
- Brain tumor
- Brain damage developed on the background of head injury;
- Sleep disturbance;
- Encephalopathy;
- Inflammation of the brain;
- Stroke
- Creutzfeldt-Jakob disease.
Electroencephalogram confirms brain death in patients with chronic coma.
The doctor uses this test to achieve an adequate level of anesthesia in people who need to be in an induced coma for the management of various diseases (usually to protect the brain).
