Can exposure to art slow the advance of Alzheimer’s Disease, or at least make its effects more bearable? The answer seems to be yes, but no one really understands why. “Art therapy, both appreciating art and making it, has been used for decades as a nonmedical way to help a wide variety of people – abused children, prisoners and cancer and Alzheimer’s patients. But much of this work has taken place in nursing homes and hospitals. Now museums like [New York’s] Modern and the Museum of Fine Arts, Boston, are trying to bring it into their galleries, using their collections as powerful ways to engage minds damaged by dementia.”
