Overview, Causes, & Risk Factors

Suicidal behaviors can accompany many emotional disturbances, including depression, bipolar disorder, and schizophrenia. More than 90% of all suicides are related to a mood disorder or other psychiatric illness.

Suicidal behaviors often occur as a response to a situation that the person views as overwhelming, such as social isolation, death of a loved one, emotional trauma, serious physical illness, growing old, unemployment or financial problems, guilt feelings, and alcohol or other drug dependence.

In the U.S., suicide accounts for about 1% of all deaths each year. The highest rate is among the elderly, but there has been a steady increase in the rate among adolescents. Suicide is now the third leading cause of death for those 15 to 19 years old, after accidents and homicide.

Suicide attempts that do not result in death far outnumber completed suicides. Many unsuccessful suicide attempts are carried out in a manner that makes rescue possible. They often represent a desperate cry for help

The method of suicide varies from relatively nonviolent methods (such as poisoning or overdose) to violent methods (such as shooting oneself). Males are more likely to choose violent methods, which probably accounts for the fact that suicide attempts by males are more likely to be completed.

Suicide attempts should always be taken seriously and mental health care should be sought immediately. Dismissing them as "attention seeking" can have devastating consequences.

Relatives of people who seriously attempt or complete suicide often blame themselves or become extremely angry, seeing the attempt or act as selfish. However, when people are suicidal, they often mistakenly believe that they are doing their friends and relatives a favor by taking themselves out of the world and these irrational beliefs often drive their behavior.
