Research Brief: Disturbed sleep linked to suicide in elderly

 Sleep disturbances in the elderly may increase the risk of suicide, according to US research presented this week at the 21st annual meeting of the Associated Professional Sleep Societies in Minnesota. The study looked at 14,456 patients, aged 60 and over, over a 10-year period. Over the time frame, 21 individuals died as a result of suicide. When each suicide was matched to 20 controls, it was found that disturbances in sleep, independent of depression, predicted an increased risk of eventual death by suicide.
