Severe worsening of parkinsonism in Lewy body dementia due to donepezil

disorders is reported. Tombini et al. raise the possibility of whether their patient’s postictal behavioral changes may be the expression of a “forced normalization-like” phenomenon, given the absence of epileptiform activity during the symptomatic period. I do not think that is the case because the duration of the psychiatric symptoms is rather short and, in forced normalization, the onset of psychiatric symptoms usually occurs after a seizure-free period.5
