Anxiety disorders involve excessive worry, fear, or nervous system activation that interferes with daily functioning. Anxiety may present as constant worry, racing thoughts, muscle tension, irritability, sleep disturbance, or avoidance of certain situations. Some individuals experience panic attacks, which can include chest tightness, shortness of breath, dizziness, or fear of losing control.

Anxiety affects both adults and children. Children and adolescents may show anxiety through avoidance, school refusal, physical complaints, or emotional outbursts. Adults may experience difficulty concentrating, chronic stress, or impaired work performance.

Treatment focuses on helping individuals understand anxiety responses, build coping skills, and reduce avoidance behaviors. Therapy may include strategies for emotional regulation, stress management, and gradual exposure. Medication management may be considered when anxiety symptoms are severe or persistent.
