Frontotemporal dementia (FTD) often presents with behavioural changes warranting treatment with antipsychotic medications. It is known that patients with Lewy body dementia are sensitive to developing extrapyramidal symptoms (EPS) from these medications. This has not been emphasized in FTD. We report three patients with FTD that developed parkinsonism and prominent antecollis after treatment with newer antipsychotics, including olanzapine, risperidone and quetiapine. Patients with FTD might have increased sensitivity to antipsychotic medications as with Lewy body dementia. Although newer antipsychotics have favourable side effect profiles, there is increasing evidence that EPS develop more frequently than previously thought.
