Unraveling the Gut-Brain Connection in Parkinson's Disease

A small study suggests that the progression of Parkinson's disease and the response to treatment may vary depending on whether the disease primarily affects the dominant or nondominant side of the body. The study evaluated typing skills in patients with Parkinson's disease and found that patients with nondominant onset showed improvement in typing skills over time with treatment, while patients with dominant onset experienced worsening of skills despite treatment. These findings suggest that the side of onset and handedness may play a role in understanding disease progression and medication response in Parkinson's disease. Further research is needed to validate these results in larger populations.
