Early Predictors of Suicide and Lithium as an Anti-Suicide Drug
At the 2019 meeting of the International Society for Bipolar Disorders, researcher Gin S. Malhi discussed early predictors of suicide in people with bipolar disorder, such as younger age of illness onset, early life stressors, and family history of suicide. Impulsivity, hopelessness, cognitive deficits and substance use are risk factors, both for suicide in general and for an imminent suicide attempt. Proximal risk factors that indicate someone may make a suicide attempt soon include: mood swings, rapid cycling, increased depression, hospitalization, and severe anxiety.
Editor’s Note: Among all psychotropic drugs, lithium has the best data supporting its anti-suicide effects, both at therapeutic doses in patients with bipolar disorder and at trace levels in the water supply in the general population. People who live in locations where more lithium is naturally present in the water supply have lower rates of suicide than those who live in places with less lithium in the water. Malhi also noted that the antioxidant N-acetylcysteine (NAC), which has positive effects on mood and habitual behaviors, can reduce the incidence of lithium-induced dysfunction of the kidneys.
