Abstract
Handedness has been a topic of scientific interest for many years. However, false and misleading ideas have dominated this field with a still limited amount of research into the association with clinical disorders like Alzheimer disease (AD). In accordance with PRISMA guidelines, PubMed, Embase, and Cochrane Library were searched for studies regarding the association of handedness and AD. Twelve articles were included. Case-control studies show that left-handedness is not a risk factor for late-onset AD (LOAD). However, nonright handedness was found to be more prevalent in patients with early-onset AD (EOAD). Moreover, handedness does not seem to affect neuropsychological performance. We also show that collapsing versus separating mixed and left-handedness may yield different results. Future research on the relation between handedness and AD may provide new insight into disease pathogenesis, improve rehabilitation, and help identify patients who will progress, aiding the design of prevention trials.
期刊介绍：
Alzheimer Disease & Associated Disorders is a peer-reviewed, multidisciplinary journal directed to an audience of clinicians and researchers, with primary emphasis on Alzheimer disease and associated disorders. The journal publishes original articles emphasizing research in humans including epidemiologic studies, clinical trials and experimental studies, studies of diagnosis and biomarkers, as well as research on the health of persons with dementia and their caregivers. The scientific portion of the journal is augmented by reviews of the current literature, concepts, conjectures, and hypotheses in dementia, brief reports, and letters to the editor.
