Which of the following is a common symptom of generalized anxiety disorder (GAD)?

Difficulty concentrating is indeed a common symptom of generalized anxiety disorder (GAD). Individuals with GAD often experience persistent worry and anxiety about a variety of life situations, which can lead to challenges in focusing on tasks, decision-making, and maintaining attention. This cognitive impairment stems from the constant state of apprehension and tension that characterizes GAD, making it hard for individuals to engage fully in activities or conversations without being distracted by their anxious thoughts.

In the context of GAD, excessive worry about different domains—such as health, finances, relationships, or work—can create mental clutter, making it difficult for these individuals to concentrate on the present moment. This symptom is significant because it can interfere with daily functioning, including work performance and personal relationships. Recognizing this symptom can help in developing effective treatment strategies, such as cognitive-behavioral therapy or medication, to mitigate the impact of anxiety on cognitive functions and overall quality of life.
