One of the earliest signs of Parkinson's disease could come at night, according to a new study.
Researchers at the University of Birmingham said early diagnosis is valuable, but the study reports there are "very few" risk indicators for the disease - and many are not specific to Parkinson's or require expensive hospital tests. The team used data from a large cohort study from the US that had data over a period of 12 years on 3,818 older men living independently.
At the beginning of the study, the men completed a range of questionnaires, one of which included a question about sleep quality. Participants reporting bad dreams at least once per week were then followed up at the end of the study to see whether they were more likely to be diagnosed with Parkinson's disease, reports the Daily Record.
