Focal bilateral motor seizures precipitated by abrupt cessation of chronic lormetazepam abuse and amitriptyline overdose.

ABSTRACT: We report the case of an adult psychiatric patient who developed new-onset focal bilateral motor seizures (FBMS) in the context of a severe benzodiazepine withdrawal syndrome. The patient was forced to interrupt chronic lormetazepam abuse and overdosed on amitriptyline (800 mg in an oral solution) before the onset of seizures. Typical signs of amitriptyline intoxication such as sedation and anticholinergic effects were not observed. Video-EEG recordings revealed a stereotypical ictal motor pattern with asymmetric tonic posturing and bilateral clonic movements of the upper limbs, but there were no abnormalities identified by EEG. Seizures recurred multiple times per day but resolved simultaneously when withdrawal symptomatology subsided eight days after onset. Nonepileptic seizures (NES) we
