Taking over-the-counter pain medicines such as ibuprofen or aspirin may reduce the risk of developing Parkinson's disease, finds a new study published in Neurology.
Ibuprofen and aspirin belong to a class of drugs called non-steroidal anti-inflammatory drugs (NSAIDs). The study found that those who regularly took NSAIDs reduced their risk of Parkinson's by as much as 60 per cent.
The study involved 579 men and women, half of whom had Parkinson's disease. The participants were asked if they had taken aspirin or a non-aspirin NSAIDs once a week or more at any point in their life for at least a month....

Studying patients who have taken an NSAID "once a week or more at any point in their life for at least a month" means studying an extremely diverse group. The range of possibilities is enormous (e.g., taking the NSAID 50 years ago and taking the NSAID last month; taking the NSAID for a month and taking the NSAID for 20 years). Far more details about usage needs to be reported for the reader to understand these results. Also, the total lack of acknowledgment that NSAIDs are extremely irritating to the stomach is a major oversight. Those who fear getting Parkinson's Disease may be propelled into taking NSAIDs without weighing this thin beneficial evidence with the well documented gastro-intestinal dangers of taking NSAIDs.
Since this evidence cited comes from a case-control study, a weak type of design it should be described with appropriate caveats. Case-control studies are one of the reasons why millions of women were taking long-term hormone replacement therapy to ward off cardiovascular disease. Until better evidence comes along just file this story under "interesting but unproven".
