WEDNESDAY, March 2 (HealthDay News) -- Regular users of ibuprofen may be reducing their risk of Parkinson's disease, according to new research that echoes previous findings.
"We found ibuprofen, a commonly used drug by Americans, could be neuroprotective against Parkinson's disease," said researcher Dr. Xiang Gao, an instructor in medicine at Harvard Medical School and a research scientist at Harvard School of Public Health. The neurological disorder causes movement problems.
"Protective effects are seen after taking ibuprofen two or more times a week," he said. "That's so-called regular use."
The finding, published online March 2 in the journal Neurology, adds to the results of previous studies, some of those conducted by Gao, showing a protective effect.
"At this time, we still don't know the exact mechanism," Gao said.
The study was funded by the U.S. National Institutes of Health.
As promising as the finding may be, Gao said there are no reasons to start taking ibuprofen to ward off the disorder, which affects 1 million Americans. "I don't recommend ibuprofen to protect against Parkinson's," he said. "We just see an association, not some causal relationship."
Another expert agreed the finding doesn't warrant taking up an ibuprofen habit to reduce Parkinson's risk. "It's way too early for that," said Dr. Michael Rezak, director of the Movement Disorder Center at Central DuPage Hospital, in Illinois.
Overdoing ibuprofen is accompanied by risks, Rezak said. "The major risk is GI hemorrhage and bleeding."
For the study, Gao analyzed data from nearly 99,000 women participating in the Nurses' Health Study and more than 37,000 men enrolled in the Health Professionals Follow-Up Study.
Participants were asked about their use of nonsteroidal anti-inflammatory drugs such as ibuprofen, and their use of other medicines such as aspiri
