The largest analysis to date of patients taking GLP-1 receptor agonists (GLP-1RAs) has investigated their effects on nearly 175 diseases, and found that compared to three other classes of diabetes medications, individuals with a prescription for GLP-1RAs had a reduced risk of 42 diseases, and an increased risk of 19.

Parkinson’s disease, characterized by progressive dopamine neuron loss, leads to motor deficits such as bradykinesia and rigidity, as well as nonmotor symptoms like cognitive decline and depression. While L-DOPA alleviates motor symptoms, long-term use often results in side effects, including motor fluctuations and dyskinesias, as well as nonmotor (psychotic-like) side effects.

The findings, which were published Jan. 20, 2025, in Nature Medicine, provide a comprehensive overview of GLP-1RAs’ effects.
