In prior studies we've participated in, we found that sleep disorders such as insomnia or nightmares may create some risk for suicidal ideation or behavior (suicidality). Other researchers have found similar findings. To our knowledge, though, there has been limited investigation of the influence of fatigue or sleepiness on sucidality, that is, from a sleep medicine perspective.
At our sleep medical facilitites, we see thousands of patients who complain of daytime fatigue and sleepiness. Some of these patients also suffer from suicidal ideation or behaviors, and we are interested in learning whether or not fatigue and sleepiness might be associated with their mental health to the point of influencing these suicidal thoughts or actions.
