A new study from the BIDMC Institute for Gut-Brain Research adds to a growing body of evidence that Parkinson’s disease, long believed to have its origins in the brain, may begin in the gut.
Gastrointestinal problems are common in patients with neurodegenerative disorders, to the point where a condition known as “institutional colon” was once thought to afflict those who lived in mental health institutions. In Parkinson’s disease, the entire gastrointestinal tract is affected, causing complications such as constipation, drooling, trouble swallowing and delayed emptying of the stomach. These symptoms often appear up to two decades before motor symptoms such as rigidity or tremor.
Our researchers found that people with upper gastrointestinal conditions — in particular, ulcers or other types of damage to the lining of the esophagus, stomach, or upper part of the small intestine — were far more likely to develop Parkinson’s disease later in life. The study was published online Thursday in JAMA Network Open.
