Generalized Anxiety Disorder
Generalized Anxiety Disorder
Generalized Anxiety Disorder (GAD) is a psychological disorder characterized by excessive, long-lasting anxiety and worry about nonspecific life events, situations, and objects. It is the most common cause of disability in the mental health field.
Pronunciation
Generalized Anxiety Disorder: /ˌdʒɛnərəˌlaɪzd æŋˈzaɪəti dɪsˈɔːrdər/
Etymology
The term "Generalized Anxiety Disorder" is derived from the English language. "Generalized" refers to the broad range of fears or worries, "Anxiety" refers to a state of unease, such as worry or fear, and "Disorder" refers to a disruption of normal physical or mental functions.
Symptoms
People with GAD may anticipate disaster and may be overly concerned about money, health, family, work, or other issues. GAD is diagnosed when a person finds it difficult to control worry on more days than not for at least six months and has three or more symptoms. This differentiates GAD from worry that may be specific to a set stressor or for a more limited period of time. GAD sufferers often suffer from insomnia, fatigue, nausea, and palpitations.
Causes
The exact cause of GAD is unknown, but a number of factors - including genetics, brain chemistry, and environmental stresses - appear to contribute to its development. It is believed that the amygdala, the part of the brain responsible for controlling the fear response, plays a central role.
Treatment
Treatment options include cognitive behavioral therapy (CBT), psychotherapy, medication, and lifestyle changes. Medications typically used are antidepressants, benzodiazepines, or antianxiety drugs.
