The New York Times (10/3, Bakalar) “Well” blog reports that, according to a study published online Oct. 2 in the journal Neurology, “depression may be an independent risk factor for Parkinson’s disease.” For the study, investigators “followed 4,634 patients with depression and 18,544 matched controls for” an entire decade. The study excluded individuals “who received a diagnosis of depression within five years of their Parkinson’s diagnosis.” This exclusion was made to rule out any possibility that depression itself could be an early symptom of Parkinson’s.
On its website, CBS News (10/3, Jaslow) reports that people “who had depression were more than three times more likely to develop Parkinson’s than those who were not depressed.” The study’s lead author “pointed out to CBS News.com that the study showed two groups in particular appeared to be at higher risk for Parkinson’s: elderly people over 65 with depression, and people with difficult-to-treat-depression, who were defined as having to alter their antidepressant treatment regimen two or more times.”
