Psychology Psychological Disorders Anxiety Disorders Anxiety is a common and normal occurrence. However, a chronic, high level of anxiety indicates an anxiety disorder. Common Anxiety Disorders Some of the more common anxiety disorders include: Generalized Anxiety Disorder: A person with generalized anxiety disorder experiences persistent and excessive anxiety or worry that lasts at least six months. Specific Phobia: A person who has specific phobia experiences intense anxiety when exposed to a particular object or situation. The person often avoids the feared object or situation because of a desire to escape the anxiety associated with it. Social Phobia: A person who has social phobia experiences intense anxiety when exposed to certain kinds of social or performance situations. As a result, the person often avoids these types of situations. Panic Disorder and Agoraphobia: A person with panic disorder experiences recurrent, unexpected panic attacks, which cause worry or anxiety. During a panic attack , a person has symptoms such as heart palpitations, sweating, trembling, dizziness, chest pain, and fear of losing control, going crazy, or dying. Panic disorder can occur with or without agoraphobia. Agoraphobia involves anxiety about losing control in public places, being in situations from which escape would be difficult or embarrassing, or being in places where there might be no one to help if a panic attack occurred. Obsessive-compulsive Disorder: A person with obsessive-compulsive disorder experiences obsessions, compulsions, or both. Obsessions are ideas, thoughts, impulses, or images that are persistent and cause anxiety or distress. A person usually feels that the obsessions are inappropriate but uncontrollable. Compulsions are repetitive behaviors that help to prevent or relieve anxiety. Post–traumatic Stress Disorder (PTSD): A person with this disorder persistently re- experiences a highly traumatic event and avoids stimuli associated with the trauma. Symptoms include increased arousal such as insomnia, irritability, difficulty concentrating, hypervigilance, or exaggerated startle response. Roots of Anxiety Disorders Many different interactive factors influence the development of anxiety disorders.

Biological Factors Many biological factors can contribute to the onset of anxiety disorders: Genetic predisposition: Twin studies suggest that there may be genetic predispositions to anxiety disorders. Researchers typically use concordance rates to describe the likelihood that a disorder might be inherited. A concordance rate indicates the percentage of twin pairs who share a particular disorder. Research has shown that identical twins have a higher concordance rate for anxiety disorders than fraternal twins.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
