It is a type of seizure caused by abnormal electrical activity in a small area of the brain.
Sometimes the cause is unknown but they have also been described linked to: trauma, infections, cancer, genetic and toxic alterations.
The symptoms depend on the area of the brain affected and may manifest as repeated movements of an area of the body, nausea, behavioural changes, sensory disturbances, slurred speech, etc. The patient does not lose consciousness and is aware that sensations experienced are not real, false feelings of already having lived the moment and sudden speech difficulty. It is different from partial complex seizures in that it does not produce loss of consciousness.
It is diagnosed through the clinical symptoms and an electroencephalography.
Treatment should be started early to treat the cause, in addition to specific epilepsy treatment.
