Behavioral-variant frontotemporal dementia


Objective: To identify distinct behavioral phenotypes of behavioral-variant frontotemporal dementia (bvFTD) and to elucidate differences in functional, neuroimaging, and progression to residential care placement.

Methods: Eighty-eight patients with bvFTD were included in a cluster analysis applying levels of disinhibition and apathy (Cambridge Behavioural Inventory-Revised) to identify phenotypic subgroups. Between-group (Kruskal-Wallis,

Rethinking cognition in Parkinson disease – Phosphodiesterase 4

The nosology and treatment options for cognitive impairment in Parkinson disease (PD) remains perhaps the greatest unmet clinical need.1 The reported frequency of mild cognitive impairment (MCI) in newly diagnosed PD has ranged from 22% to 43%.2,3 A proportion of those with PD-MCI progress to PD dementia (PDD), the prevalence of which is variously estimated between 24% and 31%,

Slowing Gait and Risk for Cognitive Impairment

Originally posted on

Methods: We assessed a cohort of older adults (n = 175, mean age 73 years, 57% female, 65% white) with repeated measures of gait speed over 14 years, MRI for gray matter volume (GMV) at year 10 or 11, and adjudicated cognitive status at year 14. Gait slowing was calculated by bayesian slopes corrected for intercepts,
