Does Parkinson's disease start in the brain or gut?

Does Parkinson's disease start in the brain or the gut? In a new contribution published in the Journal of Parkinson's Disease, scientists hypothesize that PD can be divided into two subtypes: gut-first, originating in the peripheral nervous system of the gut and spreading to the brain; and brain-first, originating in the brain, or entering the brain via the olfactory system, and spreading to the brainstem and peripheral nervous system.

Study: Regular exercise reduces cholesterol, protects the cardiovascular system

Regular exercise protects the cardiovascular system by reducing risk factors such as cholesterol and blood pressure. "But we believe there are certain risk factors for cardiovascular disease that are not fully understood," says Matthias Nahrendorf, MD, PhD, of the Center for Systems Biology at MGH.
