Bad dream in childhood increases the future risk of Parkinson's and dementia

UK: Those children experiencing bad dreams at 11 years of age are two times more likely to develop cognitive impairment and seven times more likely to develop Parkinson's disease by the age of 50 years. The role of genetics is also crucial here because one gene which increases the risk of nightmares is tied to the risk of Alzheimer's disease in old age. So the role of genetics is also implicated in this context.
Research says that those experiencing Distressing dreams in middle-aged and older adults have the risk of developing cognitive impairments like dementia and PD. There needs to be more data related to young people developing these conditions due to distressing dreams.
The study is published in The Lancet.
The research in this longitudinal analysis used data from the 1958 British Birth Cohort Study.
The children's mother gave information about distressing dreams at ages 7 (1965) and 11 (1969). The cognitive assessment, doctor-diagnosis, and multivariable Firth logistic regression determined cognitive impairment and PD at the age of 50.
