When more is more: Identifying cognitive impairments with multiple drawing tasks

Changes in drawing traits have been reported in people with early-stage cognitive impairments, but most studies have used a single drawing task only. In a study published recently in the Journal of Alzheimer’s Disease, researchers from the University of Tsukuba and IBM Research have found that they could classify people with normal cognition, mild cognitive impairment (MCI), and Alzheimer’s disease (AD) with much greater accuracy by combining traits extracted from five drawing tasks compared to using just one or two tasks.
