RESUMO

Background: Because the behavioral variant of frontotemporal dementia (bvFTD) shows major clinical overlap with primary psychiatric disorders (PPD) that affect similar neuroanatomical circuits, a common genetic vulnerability between FTD and PPD was hypothesized.Aims: We studied whether PPD are more prevalent in families of patients with sporadic frontotemporal dementia compared with healthy controls (HC), subjects with Alzheimer's disease (AD), and individuals with bipolar disorder (BD).Methods: In this case-control study performed between January 2013 and February 2019, we investigated the first-degree family history concerning depression, psychosis (including schizophrenia), BD, and autism spectrum disorder for 73 bvFTD patients, 153 patients with BD, 108 patients with AD, and 101 HC with a semistructured questionnaire (QFTD-NL 1.0) according to DSM-IV, DSM-5, or ICD-10 criteria.Results: Patients with bvFTD had a 2.58-fold higher odds of having a first-degree family member with depression compared to HC (P = .04). Furthermore, they showed 3.26-fold higher odds of having a first-degree relative with psychosis compared to HC (P = .09).Conclusions: Our results implicate a link between dementia, including sporadic bvFTD, and depression. Further study into the genetic overlap between bvFTD and PPD might provide clues to targeting common disease mechanisms.
