Ninety Percent of Parkinson's Patients Show Dream Changes 15 Years Before Diagnosis

What was said

"When men in their 50s develop Parkinson's disease and the brain withers, 90-something percent, which in medical terms is almost 100, is 15 years before their dreaming pattern changes."

Dr. Jandial presented data showing that over 90% of men who develop Parkinson's disease exhibit a specific dream disorder—REM behavior disorder—15 years prior to clinical diagnosis. This finding positions dream pattern changes as one of the earliest detectable warning signs of neurodegenerative disease, potentially opening a new window for early intervention.
