This category is to be used only for the condition associated with "idiopathic" epilepsy. Most of the etiological agents underlying chronic brain syndromes can and do cause convulsions, particularly syphilis, intoxication, trauma, cerebral arteriosclerosis, and intracranial neoplasms. When the convulsions are symptomatic of such disease, the brain syndrome is classified under those disturbances rather than here. The disturbance most commonly encountered here is the clouding of consciousness before or after a convulsive attack. Instead of a convulsion, the patient may show only a dazed reaction with deep confusion, bewilderment and anxiety. The epileptic attack may also take the form of an episode of excitement with hallucinations, fears, and violent outbreaks.
As of DSM-III, this disorder is no longer part of the DSM.
