However many researchers believe that the neurodegenerative disorder may get started far away from the brain — in the gut — and years before the first neurological signs appear.
New findings by Columbia researchers David Sulzer, PhD, and Dritan Agalliu, PhD, and two of their graduate students are adding to evidence backing this hypothesis — and showing that what triggers initial gastrointestinal changes in Parkinson’s could be a misdirected immune attack. [read more]
