Those who have trouble falling asleep within 30 minutes may be at a higher risk for developing dementia, a new study has suggested.
The research, which was published in the American Journal of Preventive Medicine, also found that sleep medication use was associated with a higher risk. Scientists set out to find if there were links between sleep disturbance and dementia.
The study looked at a nationally representative group of US adults aged 65 or over and examined 10 years' worth of data from the National Health and Aging Trends Study.
