Generalized anxiety disorder

Generalized anxiety disorder (GAD) is a common disorder characterized by long-lasting anxiety that is not focused on any one object or situation. Those with generalized anxiety disorder experience non-specific persistent fear and worry and become overly concerned with everyday matters. Generalized anxiety disorder is "characterized by chronic excessive worry accompanied by three or more of the following symptoms: restlessness, fatigue, concentration problems, irritability, muscle tension, and sleep disturbance". Generalized anxiety disorder is the most common anxiety disorder to affect older adults. Anxiety can be a symptom of a medical or substance use disorder problem, and medical professionals must be aware of this. A diagnosis of GAD is made when a person has been excessively worried about an everyday problem for six months or more. These stresses can include family life, work, social life, or their own health. A person may find that they have problems making daily decisions and remembering commitments as a result of a lack of concentration and/or preoccupation with worry. A symptom can be a strained appearance, with increased sweating from the hands, feet, and axillae, along with tearfulness, which can suggest depression. Before a diagnosis of anxiety disorder is made, physicians must rule out drug-induced anxiety and other medical causes.

In children, GAD may be associated with headaches, restlessness, abdominal pain, and heart palpitations. Typically, it begins around eight to nine years of age.
