Reward processing deficits arise early in familial frontotemporal dementia.

Reward processing involves evaluation of stimuli to inform what an individual works to pursue or avoid. Patients with behavioral variant frontotemporal dementia (bvFTD) often display reward processing changes, including insensitivity to aversive stimuli. It is unknown how early in the disease course reward changes are detectable.

Real World Financial Mismanagement in Alzheimer's Disease, Frontotemporal Dementia, and Primary Progressive Aphasia.

Background: Whereas clinical experience in dementia indicates high risk for financial mismanagement, there has been little formal study of real world financial errors in dementia.

Objective: We aimed to compare caregiver-reported financial mistakes among people with Alzheimer's disease, behavioral variant frontotemporal dementia (bvFTD), and primary progressive aphasia (PPA).

Methods: Caregivers reported whether participants with dementia had made financial mistakes within the last year; and if so, categorized these as resulting from: (a) being too trusting or gullible, (b) being wasteful or careless with money, or (c) trouble with memory.

The maturation of exploratory behavior in adolescent on two photoperiods.

Dispersal from the natal site or familial group is a core milestone of adolescent development in many species. A wild species of mouse, , presents an exciting model in which to study adolescent development and dispersal because it shows different life history trajectory depending on season of birth. born in spring and summer on long days (LD) disperse in the first 3 months of life, while born on shorter autumnal days (SD) delay dispersal through the wintertime.
