HTR1A and behavioral variant of frontotemporal dementia: Hyperorality in bvFTD probably results from the involvement of the posterior hypothalamus and severe loss of brain serotonin neurotransmission, especially in 5HT1A receptor.54 5HT1A receptors are associated, among other behaviors, with impulsivity and appetite.30 Thus, serotoninergic anti-depressants may help manage hyperorality in bvFTD patients and are well tolerated.12,25 Lebert et al. demonstrated trazodone efficacy in a sample of bvFTD patients according to NPI scores, including dietary changes.14
