New Research- Long term use of MAO-B inhibitors may slow Parkinson's progression
 

Researchers from the University of South Florida found in a retrospective analysis of clinical trial data that long-term use of monoamine oxidase type B, or MAO-B, inhibitors slows the clinical decline of patients with Parkinson's disease.

Unfortunately, the paper on which this report is based [1] is behind a paywall. But, Medicalxpress are reporting [2]:

"A one year increase in duration of MAO-B inhibitor exposure was associated with a benefit equivalent in magnitude to approximately 20% of the annual decline in Activities of Daily Living, Ambulatory Capacity, and Global Disability observed in participants not receiving an MAO-B inhibitor."
