The nerve cells and their interaction are controlled by electric impulses. Only by means of a regulated interaction are we able to think, feel, move, or absorb sensations, such as light or music. Any disturbances of this system can cause very different complaints or diseases, among others, epileptic seizures.

Epilepsy is a disease with very different manifestations. What all forms have in common is that seizures that are triggered by brain dysfunction occur from time to time. Besides a congenital predisposition to seizures, epileptic seizures, i.e. electrical failures in the brain, can be caused by injuries due to accidents, damage due to a tumor or, for example, alcohol, inflammation, cerebral hemorrhage or circulatory disorders. The electroencephalogram (EEG) is considered as the most important method of examination in the case of seizure disorders.
