Anxiety

Anxiety: Introduction

Anxiety is a feeling of worry, fear or trepidation. Mild, moderate or occasional, short-term severe anxiety is a normal reaction to stressors in daily life. Although anxiety can be unpleasant, it is a normal reaction to an environmental stressor, and a mild to moderate amount of anxiety can help people to recognize and more effectively deal with stressful situations, such as starting a new job or passing an exam. Anxiety can also be experienced without any stimulus at all or due to a perceived stressor that may not exist, such as when a child is afraid of a monster in the closet.

Anxiety can also be a symptom of a wide range of medical and mental health conditions, such as drug addiction, Alzheimer's disease, hyperthyroidism, hypertension, psychosis, and hypoxia.

If anxiety is at an extreme level or becomes recurring or continuous, it may be due to or can develop into a mental health condition, called an anxiety disorder. Common anxiety disorders include panic disorder, in which a person feels a crippling sense of panic. Agoraphobia is excessive anxiety that occurs when a person is in open spaces or public places. People with obsessive compulsive disorder try to reduce their anxieties through ritual and repeated behaviors.

Post traumatic stress disorder occurs after a traumatizing event and is characterized by flashbacks of the terrifying event. A persistent fear of public social situations is called social anxiety disorder, and generalized anxiety disorder manifests as excessive worry and anxiety that is out of proportion to the actual situation.

Anxiety can manifest in one's mood, behavior, thoughts, and emotions. Symptoms of anxiety can be mild to severe. Mild symptoms include a slight elevation in heart rate and increased alertness. More severe symptoms can include severe feelings of panic, palpitations, chest pain, and shortness of breath. For more information on symptoms, refer to symptoms of anxiety.

Making a diagnosis of the underlying cause of excessive anxiety begins with taking a thorough medical and psychiatric history, including symptoms, and completing a complete physical examination and a mental health exam. Tests are performed that can detect medical causes of anxiety, such as hyperthyroidism, hypoxia, and hypertension. A referral to a psychiatrist or other licensed mental health provider is often made to aid in the diagnosis and treatment of anxiety related to an anxiety disorder or other mental health condition.

It is possible that a diagnosis of anxiety or an anxiety disorder can be missed or delayed because symptoms can be vague, associated with other conditions, or because of the stigma associated with mental illness. For more information on misdiagnosis, refer to misdiagnosis of anxiety.

Treatment of anxiety varies depending on the underlying cause, the severity, and a person's medical history, age, and general health. For more information on treatment, refer to treatment of anxiety. ...more »
