Summary:Restless legs syndrome (RLS) is associated with an unrelenting urge to move at night, which can cause chronic sleeplessness, depression, and despondency; thus increasing risk of suicide. We aimed to determine frequency of suicidal ideation and behavior in RLS. RLS and control participants were recruited through community and RLS Foundation advertisements.

Lifetime suicidal ideation (plan) and behavior (attempt) was assessed using the Suicidal Behavior Questionnaire-revised. The Brief Lifetime Depression Scale evaluated lifetime depression history. Forward stepwise logistic regression determined the odds of suicidal ideation or behavior.

Significantly more RLS than control participants had lifetime suicidal ideation or behavior (27.1% vs. 7.0%; p
