Complications

Studies consistently report that all types of anxiety disorders can be very debilitating and seriously affect a person’s quality of life.

Association with Depression and Bipolar Disorders

Depression. Depression and nearly every anxiety disorder often go hand in hand, in both the young and old. In fact, the lifetime risk for depression in people with anxiety disorders may be higher than 70%. Furthermore, the combination of depression and anxiety is a major risk factor for both substance abuse and suicide. The following are examples of depression in specific anxiety disorders:

Between 50 - 65% of people with panic disorder also have major depression. Some studies have suggested that treating panic disorder early enough may help prevent major depression later on.
More than two-thirds of OCD patients suffer from depression.
Most patients with GAD will experience at least one episode of significant depression and many develop recurrent episodes. In patients with both disorders, GAD usually precedes the onset of depression.
Social anxiety during adolescence or young adulthood has been associated with a higher risk for depression, and the presence of both increases the chances for severe depression.
People with PTSD are four to seven times as likely to be depressed as are people without PTSD.

Bipolar Disorder. Symptoms of panic disorder are very common in people with bipolar disorder (manic-depression). In fact, people with bipolar have 26 times the rate of panic disorder as in the general population. Furthermore, anxiety worsens bipolar disorder. According to one 2000 study, anxiety disorders in teenagers were associated with bipolar disorder in adulthood, while manic behavior in adolescence was linked to later anxiety disorders.

Increased Risk for Suicide

Evidence now strongly supports an association between panic disorder and a risk for suicidal thoughts. Studies report that up to 18% of people with panic disorder attempt suicide and up to 38.5% regularly harbor suicidal thoughts, with the risks being higher in people with both panic disorder and depression. One study reported suicide attempts in about 12% of people with social phobias or OCD. If a person has an anxiety disorder and a mood disorders (such as depression), the risk for suicide is even higher.

Preventing Suicide in Adolescents

Suicide is the third most common cause of death among adolescents, and is one of the most devastating events than can happen to a family. Suicide is most commonly associated with depression in young people, but it is also commonly associated with anxiety, psychosis, substance abuse, or impulsivity. More girls attempt suicide but more boys succeed, most often because they choose guns or violent methods while girls tend to overdose, which is more treatable. Nevertheless, unsuccessful attempts are major risk factors for a later suicide. Any expression of suicidal intent should be treated very seriously.

The following are danger signs in young people:

Withdrawal from friends
Sudden decrease in school performance
Loss of interest in activities that were previously pleasurable
Unusual irritability
Unusual changes in sleep or eating habits

Risk factors for suicide include a history of neglect or abuse, history of deliberate self-harm, a family member who committed suicide (nearly always one who shared a common mood disorder), access to firearms, and living in communities where there have been recent outbreaks of suicide in young people. A romantic break-up is often the trigger for a suicidal attempt in teenagers. Feeling connected with parents and family protected young people with depression in one study, regardless of gender or ethnicity.

In one study, adolescents failed to seek help for suicidal thoughts for the following reasons:

They believed nothing would help.
They were reluctant to tell anyone they had problems.
They thought it was a sign of weakness to seek help.
They did not know where to go.

Parents should not hesitate to seek professional help for their children if they suspect they are thinking about killing themselves. This is a medical emergency and requires immediate treatment.
