123I-FP-CIT uptake and behavioral disinhibition in the frontotemporal dementia spectrum: an exploratory DAT-SPECT study.
Behavioral disinhibition is a core feature of behavioral variant frontotemporal dementia (bvFTD) and occurs across related FTD-spectrum presentations. Serotonergic dysfunction may contribute to behavioral dysregulation; therefore, we primarily examined dorsal raphe (DR)-centered midbrain ¹²³I-FP-CIT uptake as an indire...
