Study advises that patients with a consistent history of sleep disturbances should advise their health care provider who might use the information to screen for the possibility of the patient having a stroke
A new study in the Canadian Medical Association Journal (CMAJ) has found that people who suffer the effects of stroke have a much greater prevalence of having suffered from sleep disturbances.
The report published Tuesday said the issue has not been studied enough in Canada, but there is sufficient evidence that sleep disturbances could be used as a screening tool during routine medical visits so that family doctors know that their patient might possibly suffer a stroke.
The report is authored by Matthew S. Jeffers, Alison C. Pittman, Tetyana Kendzerska, Dale Corbett, Kathryn S. Hayward and Yue Chen, representing a group of physicians and scientists at the University of Ottawa, the Ottawa Hospital Research Institute and the University of Melbourne in Australia.
The study used data from people aged 18 and older who responded to sleep and chronic disease concerns in the 2017-2018 cycle of the Canadian Community Health Survey (CCHS).
"We measured sleep disturbances by self-reports of having trouble staying awake most or all of the time; either short (< 5 h) or long (> 9 h) nightly sleep duration; having trouble going to or staying asleep most or all of the time; and never, rarely or sometimes having refreshing sleep," said the study.
The CCHS survey included more than 46,000 respondents, with 682 who reported effects of stroke.
