List and describe five types of anxiety disorders.
*
1. Generalized Anxiety Disorder (GAD): People with GAD experience persistent and excessive worry or anxiety about various aspects of their life, such as work, relationships, health, or finances. These worries are often irrational and overwhelming, leading to physical symptoms like restlessness, muscle tension, difficulty concentrating, and fatigue.
2. Panic Disorder: Individuals with panic disorder experience sudden episodes of intense fear or panic known as panic attacks. These attacks are usually accompanied by physical symptoms like heart palpitations, shortness of breath, trembling, sweating, chest pain, and a sense of impending doom. Panic disorder often leads to anticipatory anxiety, as people start fearing the occurrence of future panic attacks.
3. Social Anxiety Disorder (SAD): SAD also referred to as social phobia, is characterized by an intense fear of social situations and the fear of being embarrassed, humiliated, or judged by others. People with SAD typically avoid social gatherings, public speaking, or any situation that they believe could lead to embarrassment or scrutiny. Physical symptoms like blushing, trembling, sweating, and nausea may occur during such situations.
4. Specific Phobias: Specific phobias are excessive and irrational fears of particular objects, situations, or activities. For example, individuals may have a fear of heights (acrophobia), spiders (arachnophobia), flying (aviophobia), or needles (trypanophobia). These fears often lead to avoidance behavior and can cause significant distress if individuals come into contact with their phobic stimulus.
5. Obsessive-Compulsive Disorder (OCD): OCD is characterized by intrusive and distressing thoughts (obsessions) that lead to repetitive behaviors or mental acts (compulsions). Individuals with OCD might engage in compulsions to alleviate anxiety or prevent a feared outcome. The obsessions and compulsions can be time-consuming, interfere with daily functioning, and cause significant distress. Typical obsessions include fear of contamination, the need for symmetry, and intrusive aggressive or sexual thoughts. Common compulsions involve excessive cleaning, organizing, checking, or counting.
