20.3 Health in the united states  (Page 4/20)

According to the National Institute of Mental Health (NIMH), the most common mental disorders in the United States are anxiety disorders    . Almost 18 percent of American adults are likely to be affected in a single year, and 28 percent are likely to be affected over the course of a lifetime (National Institute of Mental Health 2005). It is important to distinguish between occasional feelings of anxiety and a true anxiety disorder. Anxiety is a normal reaction to stress that we all feel at some point, but anxiety disorders are feelings of worry and fearfulness that last for months at a time. Anxiety disorders include obsessive compulsive disorder (OCD), panic disorders, posttraumatic stress disorder (PTSD), and both social and specific phobias.

The second most common mental disorders in the United States are mood disorders    ; roughly 10 percent of American adults are likely to be affected yearly, while 21 percent are likely to be affected over the course of a lifetime (National Institute of Mental Health 2005). Major mood disorders are depression, bipolar disorder, and dysthymic disorder. Like anxiety, depression might seem like something that everyone experiences at some point, and it is true that most people feel sad or “blue” at times in their lives. A true depressive episode, however, is more than just feeling sad for a short period. It is a long-term, debilitating illness that usually needs treatment to cure. And bipolar disorder is characterized by dramatic shifts in energy and mood, often affecting the individual’s ability to carry out day-to-day tasks. Bipolar disorder used to be called manic depression because of the way that people would swing between manic and depressive episodes.

Depending on what definition is used, there is some overlap between mood disorders and personality disorders    , which affect nine percent of Americans yearly. The American Psychological Association publishes the Diagnostic and Statistical Manual on Mental Disorders (DSM), and their definition of personality disorders is changing in the fifth edition, which is being revised in 2011 and 2012. In the DSM-IV , personality disorders represent “an enduring pattern of inner experience and behavior that deviates markedly from the expectations of the culture of the individual who exhibits it” (National Institute of Mental Health). In other words, personality disorders cause people to behave in ways that are seen as abnormal to society but seem normal to them. The DSM-V proposes broadening this definition by offering five broad personality trait domains to describe personality disorders, some related to the level or type of their disconnect with society. As their application evolves, we will see how their definitions help scholars across disciplines understand the intersection of health issues and how they are defined by social institutions and cultural norms.

Another fairly commonly diagnosed mental disorder is Attention-Deficit/Hyperactivity Disorder (ADHD), which statistics suggest affects nine percent of children and eight percent of adults on a lifetime basis (National Institute of Mental Health 2005). ADHD is one of the most common childhood disorders, and it is marked by difficulty paying attention, difficulty controlling behavior, and hyperactivity. According to the American Psychological Association (APA), ADHD responds positively to stimulant drugs like Ritalin, which helps people stay focused. However, there is some social debate over whether such drugs are being overprescribed (American Psychological Association). In fact, some critics question whether this disorder is really as widespread as it seems, or if it is a case of overdiagnosis.
