Introduction: This study aims to measure frequency and correlates of initial idiopathic psychiatric diagnosis in a cohort of 147 patients with Frontotemporal Dementia (FTD)-spectrum disorders.
Methods: Participants were evaluated at the National Institutes of Health in Bethesda, Maryland. Initial participant diagnoses were determined by chart review and patient and informant interviews.
Background: Changes in sexual behaviors in frontotemporal dementia (FTD) are common and multifaceted, but not well characterized.
Objective: To characterize changes in sexual behaviors and intimacy in FTD compared to corticobasal syndrome (CBS) and normal controls (NC), and to evaluate the neuroanatomical associations of these changes.
Methods: Spouses of 30 FTD patients, 20 CBS patients, and 35 NC completed the Sexual Symptoms in Neurological Illness and Injury Questionnaire (SNIQ), which captures changes in sexual interest, inappropriate sexual behaviors, and prosocial sexual behaviors.
Background: Frontotemporal dementia (FTD) is a complex disorder characterised by a broad range of clinical manifestations, differential pathological signatures, and genetic variability. Mutations in three genes-MAPT, GRN, and C9orf72--have been associated with FTD. We sought to identify novel genetic risk loci associated with the disorder.

Previous research has shown that anxiety symptoms in healthy individuals are associated with variations in the volume of brain regions, such as the amygdala, hippocampus, and the bed nucleus of the stria terminalis. Brain lesion data also suggests the hemisphere damaged may affect levels of anxiety.

We identified the hexanucleotide repeat, in the pathogenic range, in 4 (2 bv-frontotemporal dementia (FTD) and 2 FTD-amyotrophic lateral sclerosis [ALS]) out of 53 patients and 1 neurologically normal control. Interestingly, 2 of the C9ORF72 expansion carriers also carried 2 novel missense mutations in GRN (Y294C) and in PSEN-2(I146V).

Although genetic testing is available for some degenerative diseases, in most types of dementia, both genetic and environmental factors are involved. Overall, dementing diseases can be either sporadic or inherited, and in general, the earlier the onset, the more likely a disease is to be inherited. Before genetic testing is performed, the ethical issues, such as the effect the tests might have on asymptomatic children, should be considered.
