"We found that the areas in the brain involved in attention and visual processing were less connected to the rest of the brain," said study author Menno M. Schoonheim, Ph.D., from the Department of Anatomy and Neurosciences at VUMC. "This suggests that disconnection of these brain areas may contribute to the generation of visual hallucinations in patients with Parkinson's disease."
While there are no direct therapeutic implications for patient care based on the research, the authors note that future studies could indicate whether techniques that could stimulate the areas with decreased connectivity could be helpful to treat visual hallucinations in people with Parkinson's disease.
