Depression may be an early symptom of Parkinson’s diseasePublished On: Sat, Apr 28th, 2007 | Neurobiology | By BioNews
April 28 : A new study has found that depression could be an early symptom of Parkinson’s disease.
The study was conducted by a team of researchers, including Miguel Hernan at The American Academy of Neurology.
As part of the study, the researchers examined a database of over three million people in the United Kingdom. They identified 1,052 people with Parkinson’s disease and matched them with 6,634 people without the disease. Then they looked at antidepressant use before the onset of Parkinson’s disease.
The study looked at whether people who are taking antidepressant medications are more likely to develop Parkinson’s disease than people who are not taking the medications.
Researchers found that in the year before their Parkinson’s disease was diagnosed, people who were taking antidepressants were nearly twice as likely to develop Parkinson’s disease as those who were not taking antidepressants.
“This should not be interpreted as evidence that antidepressants cause Parkinson’s disease. The relationship is only apparent in the year before the onset of the disease, which suggests that depression is an early symptom of the disease,” Hernan said.
The increased risk of developing Parkinson’s in the year before diagnosis was true for both men and women, across age groups, and for those who used both types of antidepressants, tricyclic antidepressants and SSRIs, or selective serotonin reuptake inhibitors.
The findings of the research were presented at the American Academy of Neurology’s 59th Annual Meeting. (ANI)
