Complex Partial Seizures

Complex Partial 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 are often preceded by a seizure aura. The seizure aura is a simple partial seizure. The aura may manifest itself as a feeling of déjà vu, jamais vu, fear, euphoria or depersonalization. The seizure aura might also occur as a visual disturbance, such as tunnel vision or a change in the size of objects (macropsia or micropsia). Once consciousness is impaired, the person may display automatisms such as lip smacking, chewing or swallowing. There may also be loss of memory (amnesia) surrounding the seizure event. The person may still be able to perform routine tasks such as walking. Witnesses may not recognize that anything is wrong. 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.
