Toxic encephalopathy in an elderly patient: casereport
A 70-year-old woman developed toxic encephalopathy[route not stated] during treatment with carbamazepine forepilepsy.
The woman initially received carbamazepine 200mgwhich resulted in complete and rapid seizure control. Herdose was increased and, 3 days later, she was receivingcarbamazepine 300 mg/day. At that time, she developedencephalopathy with hypersomnia, confusion,psychomotor slowness, and memory impairment. EEGrecordings revealed a generalised, mild, slowing withbursts of frontal intermittent rhythmic delta activity(FIRDA). Her carbamazepine concentration was22.6 µg/mL.
Carbamazepine was discontinued and the womanreceived valproic acid instead. She improved dramaticallywithin a few days. The EEG findings of FIRDA and diffuseslowing disappeared and there was a full recovery ofphysiological activities. At her 8-month follow-up, an EEGshowed no FIRDA and there were no adverse events withvalproic acid.
