What condition is characterized by persistent worry affecting daily life?

Generalized anxiety disorder (GAD) is characterized by excessive and persistent worry about various aspects of life, such as work, health, and social interactions. This condition affects daily functioning, as individuals experience anxiety that is difficult to control and may occur more days than not for an extended period, typically for at least six months.

In GAD, the anxiety can lead to physical symptoms including restlessness, fatigue, difficulty concentrating, irritability, muscle tension, and sleep disturbances, all of which impair an individual’s ability to engage fully in everyday activities. The constant state of worry can become overwhelming, making it hard for those affected to focus or complete tasks, leading to diminished quality of life.

Other conditions listed, such as depression, post-traumatic stress disorder, and panic disorder, involve different symptoms and patterns of anxiety or mood disturbances. For instance, depression typically involves prolonged sadness and lack of interest rather than the pervasive worry seen in GAD. Post-traumatic stress disorder is linked to experiencing or witnessing a traumatic event, while panic disorder is marked by sudden attacks of intense fear and physical symptoms. Therefore, the defining feature of GAD is the chronic worry that interferes significantly with daily life functions.
