Treatment consists of exposure therapy and drug therapy. The causes of anxiety disorders are not fully known, but both psychiatric and general medical factors are involved. Many people develop anxiety disorders without any identifiable antecedent triggers. Anxiety can be a response to environmental stressors, such as the ending of a significant relationship or exposure to a life-threatening disaster.
Heart failure. A variety of drugs can cause anxiety. Corticosteroids, cocaine, amphetamines, and caffeine can directly cause anxiety symptoms, while withdrawal from alcohol, sedatives, and some illicit drugs can also cause anxiety. Anxiety can arise suddenly, as in panic, or gradually over many minutes, hours, or days.
Anxiety may last from a few seconds to years, though a longer duration is more characteristic of anxiety disorders.
Anxiety ranges from barely noticeable qualms to intense panic. The ability to tolerate a given level of anxiety varies from person to person. Anxiety disorders can be so distressing and disruptive that depression may result. Alternatively, an anxiety disorder and a depressive disorder may coexist, or depression may develop first, with symptoms and signs of an anxiety disorder occurring later.
Deciding when anxiety is so dominant or severe that it constitutes a disorder depends on several variables, and physicians differ at what point they make the diagnosis. Physicians must first use history, physical examination, and appropriate laboratory tests to determine whether anxiety is due to a general medical disorder or drug. They must also determine whether anxiety is better accounted for by another mental disorder.
Diagnosis of a specific anxiety disorder is based on its characteristic symptoms and signs.

Clinicians usually use specific criteria of the Diagnostic and Statistical Manual of Mental Disorders , Fifth Edition DSM-5 , which describes the specific symptoms and requires exclusion of other causes of symptoms. A family history of anxiety disorders helps in making the diagnosis because some patients appear to inherit a predisposition to the same anxiety disorders that their relatives have, as well as a general susceptibility to other anxiety disorders. It is a complex, long-term condition that affects about one percent of people in the United States.

The DSM-5 diagnostic criteria specify that two or more symptoms of schizophrenia must be present for a period of at least one month. Diagnosis also requires significant impairments in social or occupational functioning for a period of at least six months. The onset of schizophrenia is usually in the late teens or early 20s, with men usually showing symptoms earlier than women.
Earlier signs of the condition that may occur before diagnosis include poor motivation, difficult relationships, and poor school performance. The National Institute of Mental Health suggests that multiple factors may play a role in causing schizophrenia including genetics, brain chemistry, environmental factors, and substance use. While there is no cure for schizophrenia, there are treatments available that make it possible to manage the symptoms of the condition.
Treatments usually incorporate antipsychotic medications, psychotherapy, self-management, education, and social support.
What are the five major types of anxiety disorders?

The obsessions and compulsions must also be time-consuming taking up an hour or more per day or cause significant distress or functional impairment, must not be attributable to another medical condition or substance use, and must not be better explained by another psychiatric condition such as generalized anxiety disorder.
Treatments for OCD usually focus on a combination of therapy and medications. Antidepressants such as clomipramine or fluoxetine may also be prescribed to manage symptoms. Personality disorders are characterized by an enduring pattern of maladaptive thoughts, feelings, and behaviors that can cause serious detriments to relationships and other life areas.
