Anxiety disorders represent a class of mental health conditions characterized by excessive, persistent, and often debilitating anxiety that significantly interferes with daily life. These disorders are distinct from normal apprehension, involving physical and psychological symptoms such as excessive worry, restlessness, difficulty concentrating, and physiological arousal (e.g., increased heart rate, muscle tension). They are categorized based on their manifestations, including generalized anxiety disorder, panic disorder, and social anxiety disorder. Diagnosis typically involves a comprehensive assessment by qualified health professionals, and treatment is multidisciplinary, often involving psychotherapy, such as cognitive-behavioral techniques, alongside pharmacological management to regulate neurotransmitter levels and alleviate symptoms.
