A team of American scientists from the University of Birmingham called nightmares a possible precursor to Parkinson’s disease in the elderly. The results of the study are described in the journal EClinicalMedicine.
To do this, experts analyzed 12-year data of 3818 elderly men from the United States who lived independently, without anyone’s care. Participants in the experiment were asked to fill out questionnaires, which, in particular, were questions about the quality of sleep. It turned out that those subjects who had nightmares at least once a week were more prone to the appearance of such neurodegenerative diseases as Parkinson’s disease. According to the researchers, frequent nightmares in the elderly increased the chances of detecting this ailment in patients in the next five years, so it could probably be a biomarker.
Going forward, the scientists want to conduct additional trials with a larger sample of participants, as well as to study the connection between dreams and other diseases of the nervous system, such as Alzheimer’s disease.
In April 2022, doctors from Southmead Hospital in Bristol (UK) cured a man of Parkinson’s disease for the first time by implanting a brain implant.
