Generalized Anxiety Disorder (GAD) is characterized by excessive and ‘all-consuming’ worry that occurs across many life domains (e.g. health, work, finances, and relationships). Individuals with GAD may excessively worry about actual events or may expect the worst even when there is no apparent reason for concern. For most, physical symptoms are present such as muscle tension, headaches, and difficulty falling asleep. Reports of difficulty paying attention to other things when in the midst of worrying is also a common feature.
