Anxiety is a normal human emotion. Many people feel anxious, or nervous, when faced with a problem at work, or before taking a test or making an important decision. Anxiety disorders, however, are different. They can cause such distress that it interferes with a person's ability to lead a normal life.
An anxiety disorder is a serious mental illness. People with anxiety disorders respond to certain things or situations with fear and dread, as well as physical signs of anxiety such as a pounding heart and sweating. For people with anxiety disorders, worry and fear are constant and overwhelming, and can be crippling. An anxiety disorder is diagnosed if the person's response is not appropriate for the situation, if the person cannot control the response or if the anxiety interferes with normal functioning. Anxiety disorders can get worse if not treated; however, effective treatments are available.
There are several recognized anxiety disorders, including the following:
People with this disorder have feelings of terror that strike suddenly and repeatedly with no warning. Other symptoms of a panic attack include sweating, chest pain, palpitations (unpleasant sensations of irregular heartbeats) and a feeling of choking, which might make the person feel like he or she is having a heart attack or "going crazy."
PTSD is a condition that can develop following a traumatic and/or terrifying event, such as a sexual or physical assault, the unexpected death of a loved one, or a natural disaster. People with PTSD often have lasting and frightening thoughts and memories of the event, and tend to be emotionally numb.
Social anxiety disorder
Also called social phobia, social anxiety disorder involves overwhelming worry and self-consciousness about everyday social situations. The worry often centers on a fear of being judged by others, or behaving in a way that might cause embarrassment or lead to ridicule.
A specific phobia is an intense fear of a specific object or situation, such as snakes, heights or flying. The level of fear usually is inappropriate to the situation and might cause the person to avoid common, everyday situations.
Generalized anxiety disorder
This disorder involves excessive, unrealistic worry and tension, even if there is little or nothing to provoke the anxiety.
Anxiety disorders affect about 40 million adult Americans. They are the most common mental illnesses in the U.S. Most anxiety disorders begin in childhood, adolescence and early adulthood. They occur more often in women than in men.
The exact cause of anxiety disorders is not known; but anxiety disorders — like other forms of mental illness — are not the result of personal weakness, a character flaw or poor upbringing. As scientists continue their research on mental illness, it is becoming clear that many of these disorders are caused by a combination of factors, including biology and environmental stresses.
Like certain illnesses, such as diabetes, anxiety disorders might be caused by chemical imbalances in the body. Studies have shown that severe or long-lasting stress can change the balance of chemicals in the brain that control mood. Studies also have shown that anxiety disorders run in families, which means that they can be inherited from one or both parents, like hair or eye color. In addition, certain environmental factors — such as a trauma or significant event — might trigger an anxiety disorder in people who have an inherited susceptibility to developing the disorder.
Symptoms vary depending on the type of anxiety disorder, but general symptoms of anxiety include:
If symptoms are present, the doctor will begin an evaluation by performing a complete medical history and physical examination.
Although there are no laboratory tests to specifically diagnose anxiety disorders, the doctor might use various diagnostic tests to rule out physical illness as the cause of the symptoms.
If no physical illness is found, the person might be referred to a psychiatrist or psychologist, mental health professionals who are specially trained to diagnose and treat mental illnesses. Psychiatrists and psychologists use specially designed interview and assessment tools to evaluate a person for an anxiety disorder. The doctor bases his or her diagnosis on the patient's report of the intensity and duration of symptoms — including any problems with daily functioning caused by the symptoms — and the doctor's observation of the patient's attitude and behavior. The doctor then determines if the patient's symptoms and degree of dysfunction indicate a specific anxiety disorder. The standard reference manual used for the diagnosis of recognized mental illnesses in the United States is the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), published by the American Psychiatric Association.
Anxiety disorders are real disorders that require treatment. Recovery is not simply a matter of will and self-discipline. Fortunately, much progress has been made in the last two decades in the treatment of people with mental illnesses. Although the exact treatment approach depends on the type of disorder, one or a combination of the following therapies might be used for most anxiety disorders:
Medicines used to reduce the symptoms of anxiety disorders include antidepressants and anxiety-reducing medications.
Psychotherapy (a type of counseling) addresses the emotional response to mental illness. It is a process in which trained mental health professionals help people by talking through strategies for understanding and dealing with their disorder. The most common type of psychotherapy used with anxiety disorders is cognitive-behavioral therapy. In this type of therapy, the person learns to recognize and change thought patterns and behaviors that lead to troublesome feelings.
Anxiety disorders cannot be prevented; however, there are some things you can do to control or decrease symptoms:
Early diagnosis and treatment can limit the problems caused by an anxiety disorder and improve the outlook. Unfortunately, many anxiety disorders are not recognized and, as a result, not treated.
