Neurologists at St. Michael's Hospital in Toronto found that artists suffering from vascular dementia may still be able to draw spontaneously and from memory, despite being unable to complete simple, everyday tasks.
"We discovered that there is a disproportion between the degree that artists lose some of their memory function, their orientation and other day-to-day cognitive functions. But at the same time, some of their art form is preserved," Dr. Luis Fornazzari, a neurological consultant at St. Michael’s Hospital memory clinic and lead author of the paper, told CBC News.
Artists compared with non-artists are better protected, he added. "Due to their art, the brain is better protected [against] diseases like Alzheimer's, vascular dementia, and even strokes. They have more reserve in their brain in order to give functions.
"So [we know], based on other neuroscience studies, that art in any of its forms uses different neuronal avenues inside the brain to do their work. And the activity, the talent and the art per se gives reserve when the brain requires that reserve.
