Partial Complex Seizures

Partial Complex Seizures

A complex partial seizure is an epileptic seizure that is associated with bilateral cerebral hemisphere involvement and causes impairment of awareness or responsiveness, i.e. alteration of consciousness. Complex partial seizures might arise from any lobe of the brain. Complex partial seizures most commonly arise from the mesial temporal lobe, particularly the amygdala, hippocampus, and neocortical regions. A common associated brain abnormality is mesial temporal sclerosis. Mesial temporal sclerosis is a specific pattern of hippocampal neuronal loss accompanied by hippocampal gliosis and atrophy. Complex partial seizures occur when excessive and synchronous electrical brain activity causes impaired awareness and responsiveness. The abnormal electrical activity might spread to the rest of the brain and cause a secondary generalized tonic–clonic seizure.
