Anxiety disorders have high rates of comorbidity with major depression and alcohol and drug abuse. Some of the increased morbidity and mortality associated with anxiety disorders may be related to this high rate of comorbidity. Anxiety disorders may contribute to morbidity and mortality through neuroendocrine and neuroimmune mechanisms or by direct neural stimulation, (eg, hypertension or cardiac arrhythmia). Chronic anxiety may be associated with increased risk for cardiovascular morbidity and mortality.
Considerable evidence shows that social phobia (social anxiety disorder) results in significant functional impairment and decreased quality of life.
Severe anxiety disorders may be complicated by suicide, with or without secondary mood disorders (eg, depression). The Epidemiological Catchment Area study found that panic disorder was associated with suicide attempts (odds ratio = 18 compared with populations without psychiatric disorders). How much of the association of panic disorder with suicide is mediated through the association of panic disorder with mood and substance abuse disorders is unclear. Acute stress may play a role in producing suicidal behavior. The presence of any anxiety disorder, phobias included, in combination with a mood disorder appears to increase likelihood of suicide attempts compared with a mood disorder alone. Suicide attempts can be precipitated by adverse life events such as divorce or financial disaster. The effects of acute stress in producing suicidal behavior are increased in those with underlying mood, anxiety, and substance abuse problems.
Interestingly, in clinical samples, over 95% of the patients reporting agoraphobia also present with panic disorder, while in epidemiologic samples, simple agoraphobia appears to be more prevalent than panic disorder with agoraphobia.
