Frequent disturbing dreams in adults over 60 may signal a much higher risk of dementia, according to a global study.
Adults in their 60s who frequently have disturbing dreams may face a significantly higher risk of developing dementia, according to a large international study of over 10,000 people across Asia, Europe, and South America.
The research, led by the University of New South Wales, found that those with recurring bad dreams were nearly four times more likely to develop dementia, with men experiencing weekly disturbing dreams facing more than a threefold increase in Alzheimer’s risk.
While the study controlled for sleep issues, health conditions, medications, and genetics, researchers say disturbing dreams may signal early brain changes linked to dementia, possibly due to neurological or stress-related shifts.
However, not everyone with bad dreams will develop dementia, and further research is needed to confirm the connection.
