GLP-1, Parkinson’s Disease, and Neuroprotection

This editorial discusses the potential of GLP 1 receptor agonists, specifically lixisenatide, as a neuroprotective treatment for Parkinson’s disease (PD). A trial reported in the same issue showed that lixisenatide halted symptom progression (measured by MDS-UPDRS scores) over 12 months in early PD patients, though gastrointestinal side effects were common. The author contextualizes these findings with prior studies of exenatide, another GLP 1 agonist, which also showed persistent benefits post washout. While the clinical impact of a modest 3 point MDS-UPDRS improvement is debated, the possibility of cumulative long term benefits offers hope for slowing PD progression. Challenges include tolerability and the need for longer trials to confirm disease modifying effects. The editorial underscores GLP 1 agonists’ dual role in diabetes management and potential PD neuroprotection, linking reduced brain inflammation to their mechanism.
