Two studies by neurological researchers at Rush University Medical Center suggest that, in the future, colonic tissue obtained during either colonoscopy or flexible sigmoidoscopy may be used to predict who will develop Parkinson's disease, a neurodegenerative disorder of aging that that leads to progressive deterioration of motor function due to loss of neurons in the brain that produce dopamine, a neurotransmitter essential to executing movement.
