Gagnon, Jean-François
Background/aims: Mild cognitive impairment (MCI) is frequent in Parkinson’s disease (PD) and idiopathic REM sleep behavior disorder (iRBD). However, only a few studies have evaluated the validity of brief cognitive measures to detect MCI in PD or iRBD using standard diagnostic criteria for MCI. Our aim was to evaluate the validity of the Mini-Mental State […]

Background: Cognitive status has been reported to be an important predictor of rehabilitation outcome. The Montreal Cognitive Assessment (MoCA) was designed to overcome some of the limitations of established cognitive screening tools such as the Mini-Mental State Examination (MMSE). The purpose of this study is to evaluate the psychometric characteristics of the MoCA as a […]
A randomized controlled trial of estrogen treatment in men with mild cognitive impairment
This randomized, placebo-controlled, cross-over study investigated whether estrogen treatment would have a beneficial effect on tests of verbal memory in men with mild cognitive impairment (MCI). Forty-three men newly diagnosed with MCI were administered a battery of neuropsychological tests before randomly receiving 12 weeks of treatment with estrogen or placebo followed by a 12 week […]

Background: vascular dementia (VaD) and mixed Alzheimer’s disease (AD/VaD) are common. How best to monitor treatment is not clear. Our objective was to compare responsiveness and construct validity of change scores, following donepezil treatment, of the standardized Mini-Mental State Examination (sMMSE) and other measures potentially usable in primary care.; Methods: A six-month, outcome measurement study. […]
