Abstract

DURING recent years it has become increasingly evident that patients with temporal lobe seizures constitute one of the largest groups among those who have epileptic attacks. The origin of epileptogenic discharge in various parts of the temporal cortex produces a variety of initiating seizure phenomena, such as abdominal aura, cephalic aura, olfactory aura, psychical hallucinations (or dream states), illusions of perception (e. g., déjà vu phenomena), and automatism.

In a series of 157 cases of seizures originating in the temporal lobe, we have analyzed the anatomical location and pathology of the abnormalities which were found on surgical exploration and cortical excision. In 100 of these cases (approximately 63%) the pathological findings suggested that compression or anoxia during birth or infancy was the cause. It is this group of cases that we wish to discuss particularly. In the remaining 57 cases we found evidence of postnatal injury, intracranial infection, or neoplasm
