“I thought I would be smart, take care of myself, and not go out as much,” Sideman says. He managed to find ways to build his business without leaving his home office. After he had a panic attack on a freeway, he decided to avoid driving on the freeway — a tough stand to take in Los Angeles. He kept withdrawing from activities to try to avoid panic attacks, but that never solved the problem, he says, and after two and a half years, he realized the attacks were getting worse.
Obsessive-compulsive and related disorders are characterized by obsessive, intrusive thoughts (e.g. constantly worrying about staying clean, or about one's body size) that trigger related, compulsive behaviors (e.g. repeated hand-washing, or excessive exercise). These behaviors are performed to alleviate the anxiety associated with the obsessive thoughts. These types of disorders can restrict participation in everyday life and/or generate significant distress, for instance, by making it difficult to leave the house without many repetitions of a compulsive behavior (e.g. checking that the doors are locked). Periodically experiencing worry or having a few "idiosyncratic" habits does not constitute an obsessive-compulsive or related disorder. Instead, these disorders are characterized by unusually high levels of worry and related compulsive behaviors, in comparison with a typical range of individuals.
Panic disorder affects 2-3% of people every year in the United States and Europe, with varying rates depending on race and ethnicity. On average, Native American Indian populations experience panic disorder at higher rates than non-Latino white Americans. In contrast, African Americans, Latinos, Caribbean Blacks, and Asian Americans all experience the disorder at lower rates than non-Latino white Americans. In addition, it has been well established than females are twice as likely to be diagnosed with panic disorder than males (Asnaani, Gutner, Hinton, & Hofmann, 2009; McLean, Asnaani, Litz, & Hofmann, 2011). A number of factors (e.g., biological influences, temperament, exposure to stressors and trauma, cognitive factors, and environmental factors) have been identified as possibly influencing sex differences in rates of panic disorder (McLean & Anderson, 2009). However, no one theory has been determined so the underlying reason for sex differences in rates of panic disorder remains unknown.

Yes. There are many medications that have FDA approval to treat anxiety disorders. Several members of the benzodiazepine class are routinely used to provide relief from anxiety. These minor tranquillizers are safe and effective, but should be used for short-term relief. They have many side effects, including drowsiness, and can be habit forming at higher doses. People taking these medications should not use heavy machinery or drive until they understand how the medication might affect them.
To the extent that a person is fearful of social encounters with unfamiliar others, some people may experience anxiety particularly during interactions with outgroup members, or people who share different group memberships (i.e., by race, ethnicity, class, gender, etc.). Depending on the nature of the antecedent relations, cognitions, and situational factors, intergroup contact may be stressful and lead to feelings of anxiety. This apprehension or fear of contact with outgroup members is often called interracial or intergroup anxiety.[34]
People with generalized anxiety disorder (GAD) display excessive anxiety or worry, most days for at least 6 months, about a number of things such as personal health, work, social interactions, and everyday routine life circumstances. The fear and anxiety can cause significant problems in areas of their life, such as social interactions, school, and work.
