About

The purpose of this study is to compare characteristics of gait and balance measured among patients with Alzheimer's disease or related disorders separated into 3 groups according to the stage of disease (i.e., pre-dementia, mild and moderate dementia stages); to determine the effects of anti-dementia drugs and vitamin D on cognitive motor abnormalities; and to establish a database at Angers University Memory Centre.

Full description

Although gait disorders are frequently associated with Alzheimer's disease and related disorders (ADRD), few studies have focused on cognitive motor effects of anti-dementia drugs and vitamin D.

The objectives of this study are to

• Compare characteristics of gait and balance measured among patients with ADRD separated into 3 groups according to stages of disease (i.e., pre-dementia, mild and moderate dementia stages)
• To determine the effects of anti-dementia drugs and vitamin D on cognitive motor abnormalities
• To determine whether motor abnormalities could be associated with cognitive impairments, specifically executive dysfunctions
• To establish a database at Angers University Memory Center.
