A case of prolonged confusion after temporal lobe psychomotor status

A 36-year-old man with prolonged confusion developed after psychomotor status was reported. He had no past history of epileptic seizures or psychotic disorders. The status continued for 20 hours, and twilight state and a slight fever lasted for about 10 days. Thereafter gross impairment of memory and disorientation became remarkable, and, in addition, strong psychic and autonomic disturbances developed, such as visual and auditory hallucinations, excessive excitement, disturbance of sleep, polyphagia, polydypsia, polyuria and hyperhidrosis. The CT scan, carotide angiography, CSF examination, and complement fixation tests for viruses were all within normal limits. The EEGs showed a slowing of the background activity, 0.6--0.8 Hz periodic high voltage wave discharges and random spikes in each temporal area. The clinical symptoms and EEG findings gradually improved without remarkable damage.
