What is epilepsy?
Epilepsy is an illness characterized by the repetition of epileptic seizures due to hyperactivity of certain brain nerve cells or neurons. Seizures include a set of manifestations marked by short episodes of loss of consciousness and sensitive, psychic, or functional alterations that are more or less accompanied by spasms or contractions of skeletal musculature of convulsive type. Epilepsy is caused by abnormal alteration of the electrical activity of some neurons, generally located at the level of the cerebral cortex.
The diagnosis of epilepsy includes the use of several instrumental examinations; the electroencephalogram (EEG) will be employed to record the electrical activity of the brain.
It is important to note that these signals are changed even in the absence of symptoms in about half of the cases. Other tests such as CT or MRI scans intend to investigate the presence of brain lesions.
