| Frequently Asked Questions About Suicide
What should you do if someone tells you they are thinking about suicide?
If someone tells you they are thinking about suicide, you should take their distress seriously, listen nonjudgmentally and help them get to a professional for evaluation and treatment. People consider suicide when they are hopeless and unable to see alternative solutions to problems. Suicidal behavior is most often related to a mental disorder (depression) or to alcohol or other substance abuse. Suicidal behavior is also more likely to occur when people experience stressful events (major losses, incarceration).
If someone is in imminent danger of harming himself, do not leave the person alone. You may need to take emergency steps to get help, such as calling 911. When someone is in a suicidal crisis, it is important to limit access to firearms or other lethal means of committing suicide.
Why do men commit suicide more often than women do?
More than four times as many men as women die by suicide but women attempt suicide more often during their lives than do men and women report higher rates of depression. Several explanations have been offered:
- Completed suicide is associated with aggressive behavior that is more common in men, and which may in turn be related to some of the biological differences identified in suicidality.
- Men and women use different suicide methods. Women in all countries are more likely to ingest poisons than men. In countries where the poisons are highly lethal and/or where treatment resources scarce, rescue is rare and hence female suicides outnumber males.
Who is at highest risk for suicide in the United States?
There is a common perception that suicide rates are highest among the young. However, it is the elderly, particularly older white males, that have the highest rates. And among white males 65 and older, risk goes up with age. White men 85 and older have a suicide rate that is six times that of the overall national rate.
Why are rates so high for this group? White males are more deliberate in their suicide intentions; they use more lethal methods (firearms) and are less likely to talk about their plans. It may also be that older persons are less likely to survive attempts because they are less likely to recuperate. More than 70 percent of older suicide victims have been to their primary care physician within the month of their death, many with a depressive illness that was not detected. This has led to research efforts to determine how to best improve physicians’ abilities to detect and treat depression in older adults.
Is suicide related to impulsiveness?
Impulsiveness is the tendency to act without thinking through a plan or its consequences. It is a symptom of a number of mental disorders, and, therefore, it has been linked to suicidal behavior, usually through its association with mental disorders and/or substance abuse. The mental disorders with impulsiveness most linked to suicide include:
- borderline personality disorder among young females
- conduct disorder among young males
- antisocial behavior in adult males
- alcohol and substance abuse among young and middle-aged males
Impulsiveness appears to have a lesser role in older adult suicides. Attention-deficit hyperactivity disorder that has impulsiveness as a characteristic is not a strong risk factor for suicide by itself. Impulsiveness has been linked with aggressive and violent behaviors including homicide and suicide. However, impulsiveness without aggression or violence present has also been found to contribute to risk for suicide.
What biological factors increase risk for suicide?
Researchers believe that both depression and suicidal behavior can be linked to decreased serotonin in the brain. Low levels of a serotonin metabolite, 5-HIAA, have been detected in cerebral spinal fluid in persons who have attempted suicide, as well as by postmortem studies examining certain brain regions of suicide victims. One of the goals of understanding the biology of suicidal behavior is to improve treatments. Scientists have learned that serotonin receptors in the brain increase their activity in persons with major depression and suicidality, which explains why medications that desensitize or down-regulate these receptors (such as the serotonin reuptake inhibitors, or SSRIs) have been found effective in treating depression. Currently, studies are underway to examine to what extent medications like SSRIs can reduce suicidal behavior.
Can the risk for suicide be inherited?
There is growing evidence that familial and genetic factors contribute to the risk for suicidal behavior. Major psychiatric illnesses, including bipolar disorder, major depression, schizophrenia, alcoholism and substance abuse, and certain personality disorders, which run in families, increase the risk for suicidal behavior. This does not mean that suicidal behavior is inevitable for individuals with this family history; it simply means that such persons may be more vulnerable and should take steps to reduce their risk, such as getting evaluation and treatment at the first sign of mental illness.
Does depression increase the risk for suicide?
Although the majority of people who have depression do not die by suicide, having major depression does increase suicide risk compared to people without depression. The risk of death by suicide may, in part, be related to the severity of the depression. New data on depression that has followed people over long periods of time suggests that about 2 percent of those people ever treated for depression in an outpatient setting will die by suicide. Among those ever treated for depression in an inpatient hospital setting, the rate of death by suicide is twice as high (4 percent). Those treated for depression as inpatients following suicide ideation or suicide attempts are about three times as likely to die by suicide (6 percent) as those who were only treated as outpatients. There are also dramatic gender differences in lifetime risk of suicide in depression. Whereas about 7 percent of men with a lifetime history of depression will die by suicide, only 1 percent of women with a lifetime history of depression will die by suicide.
Another way about thinking of suicide risk and depression is to examine the lives of people who have died by suicide and see what proportion of them were depressed. From that perspective, it is estimated that about 60 percent of people who commit suicide have had a mood disorder (for example, major depression, bipolar disorder, dysthymia). Younger persons who kill themselves often have a substance abuse disorder in addition to being depressed.
Does alcohol and other drug abuse increase the risk for suicide?
Alcohol and substance abuse problems contribute to suicidal behavior in several ways. Persons who are dependent on substances often have a number of other risk factors for suicide. In addition to being depressed, they are also likely to have social and financial problems. Substance use and abuse can be common among persons prone to be impulsive, and among persons who engage in many types of high-risk behaviors that result in self-harm. Fortunately, there are a number of effective prevention efforts that reduce risk for substance abuse in youth, and there are effective treatments for alcohol and substance use problems. Researchers are currently testing treatments specifically for persons with substance abuse problems who are also suicidal, or have attempted suicide in the past.
What does "suicide contagion" mean, and what can be done to prevent it?
Suicide contagion is the exposure to suicide or suicidal behaviors within one's family or one's peer group or through media reports of suicide that can result in an increase in suicide and suicidal behaviors. Direct and indirect exposure to suicidal behavior has been shown to precede an increase in suicidal behavior in persons at risk for suicide, especially in adolescents and young adults. In addition, information such as hotlines or emergency contacts should be provided for those at risk for suicide.
Following exposure to suicide or suicidal behaviors within one's family or peer group, suicide risk may be minimized by having family members, friends, peers and colleagues of the victim evaluated by a mental health professional. Persons deemed at risk for suicide should then be referred for additional mental health services.
Is it possible to predict suicide?
At the current time there is no definitive measure to predict suicide or suicidal behavior. Researchers have identified factors that place individuals at higher risk for suicide, but very few persons with these risk factors will actually commit suicide. Risk factors include mental illness, substance abuse, previous suicide attempts, family history of suicide, history of being sexually abused and impulsive or aggressive tendencies. Suicide is a relatively rare event and it is therefore difficult to predict which persons with these risk factors will ultimately commit suicide.
