We contrasted the effects of dextroamphetamineand quetiapine, an atypical antipsychotic oftenused to treat agitation in dementia patients with cognitive andbehavioral symptoms, in 8 patients with behavioral-variantfrontotemporal dementia (FTD) in a double-blind crossovertrial. We were interested in testing a stimulant for several reasons:(1) there is autopsy, cerebrospinal fluid, and imaging evidenceof dopaminergic deficiencies in FTD (reviewed in Hueyet al.); (2) there is a clinical association between FTD and basalganglia dopaminergic dysfunction (i.e., parkinsonism); and (3)executive dysfunction associated with psychiatric illness (e.g.,attention-deficit/hyperactivity disorder) can improve with dopamineaugmentation.’ ‹
