Risk of Parkinson’s disease in individuals diagnosed with post-traumatic stress disorder

Takeaway

  • Individuals previously diagnosed with post-traumatic stress disorder (PTSD), particularly men, should be closely monitored as they are at increased risk of developing Parkinson’s disease (PD) in later life.

Why this matters

  • PD is the second most common neurodegenerative disease associated with multiple environmental, behavioral, and biological risk factors. PTSD is a mental disorder that occurs as a result of exposure to a traumatic event and is associated with an increased risk of various disorders, including dementias. Data on the link between PTSD and PD is scarce.

  • Greater insights into the link between PTSD and PD may lead to earlier interventions in afflicted individuals.
