Further strengthening a long-held debate about whether infection increases the risk for movement disorders over the long-term, a large case-control study revealed that the risk of Parkinson’s Disease was elevated by approximately 90% for the disease that occurred more than 15 years after influenza infection and by more than 70% for PD occurring more than 10 years after the flu. This study, published in JAMA Neurology, suggests that there are potential long-term consequences from influenza, though not definitive by any means.
