Methamphetamine and Parkinson’s disease



After discussing the chance that methamphetamine can increase the risk of Parkinson’s disease, I was interested in reading the research about that. Therefore, I chose to read and summarize the article, “Incidence of Parkinson’s disease among Hospital Patients with Methamphetamine-use Disorders.” During lecture, we learned that methamphetamine causes neurodegeneration, which is also what occurs in patients of Parkinson's disease.
This experiment was an observational study, taking data from all California hospitals’ discharge records. The individuals had methamphetamine-related conditions and were at least fifty years of age when viewed for the study. They were followed for ten years and reported any participants developing Parkinson’s disease. One group from the hospital included individuals that had appendicitis. This group showed no difference in Parkinson’s disease occurrences from the control group of healthy citizens.
The group with methamphetamine consumption showed a higher number of Parkinson’s disease in comparison to other observed groups. Limitations on the study were also discussed in the article. They claimed the hospital admissions could create bias, as well as diagnostic errors.
The data shows methamphetamine addicts can have a higher chance of a Parkinson’s disease diagnosis. However, more studies should be done to increase the accuracy in the hypothesis. I would be interested in seeing more information supporting or refuting the conclusions.
