Description
Psychological Disorders There are many different types of psychological disorders, and we find ourselves asking the question where do we draw the line between someone who is depressed (cannot get out of bed for weeks) compared to someone who has experienced a traumatic loss (unable to return to social activities)? - How should we DEFINE psychological disorders? - How should we UNDERSTAND disorders—as sicknesses that need to be diagnosed and cured, or as natural responses to a troubling environment? - How should we CLASSIFY psychological disorders? And can we do so in a way that allows us to help people without stigmatizing them with labels? Defining Psychological Disorders – how should we draw the line between normality and disorder? o Mental health workers view psychological disorders as patterns of thoughts, feelings or actions that are deviant, distressful, and dysfunctional. (Comer, 2004;Stein et al. 2010). o Being different (DEVIANT) from most other people in ones culture is part of what it takes to define a disorder. o Standards are varying by context and culture and also with time. o The American Psychiatric Association had dropped homosexuality as a disorder because more and more of its members no longer viewed it as a psychological problem. (Hatzenbuehler et al. 2009; Meyer 2003) o In this new century, controversy is the frequent diagnosis of ADHD in children. o But there is more to a disorder than just being DEVIANT. o Such as: Gold medalists deviate from the norm in their physical abilities, and society honors them. o Social deviance – which some political regimes use to diagnose and isolate their opponents, may bring dishonor. But to be disordered, deviant behavior usually causes the person DISTESS. o Deviant and distressful behaviors are more likely considered disordered when also judged to be a harmful dysfunction (Wakefield, 1992, 2006). o Dysfunction is key to defining disorder: An intense fear of spiders may be deviant, but if it doesn’t impair your life it is not a disorder. ADHD: normal high energy or genuine disorder? Attention-Deficit Hyperactivity Disorder (ADHD)  a psychological disorder marked by the appearance by age 7 of one or more key symptoms: extreme inattention, hyperactivity, and impulsivity. ▯ What is actually known about the causes of ADHD?  - We know that is not caused by too much sugar or poor schooling. - There is mixed evidence suggesting that extensive TV watching and video gaming are associated with a learning disorder or with defiant and temper-prone behavior. - ADHD is HERITABLE, and research teams are sleuthing the culprit genes and abnormal neural pathways (Nikolas & Burt, 2010; Poelmans et al., 2011; Volkow et al., 2009; Williams et al., 2010). Is it treatable? Yes. - Medications such as Adderall and Ritalin, which are considered stimulants but help calm hyperactivity and increase ones ability to sit and focus on a task (seriously that shit works so well) [Barbarsei et al., 2007] - Psychological therapies, such as those focused on shaping behaviors in the classroom and at home, have also helped address the distress of ADHD (Fabiano et al., 2008) Basically, extreme inattention, hyperactivity, and impulsivity can derail social, academic, and vocational achievements, and these symptoms can be treated with medications and other kinds of treatment. But the debate will always continue whether normal rambunctiousness is too often diagnosed as a psychiatric disorder, and whether there is a cost to using medicine. ▯ Understanding Psychological Disorders: How do the medical model and the biopsychosocial approach understand psychological disorders? - People in earlier times often presumed the work of strange forces— the movement of the stars, god-like powers, or evil spirits. - Until the last two centuries, “mad” people were held like animals and sometimes caged in zoo-like conditions. They were given therapies appropriate to the demon (beatings, burning or castration) The Medical Model  (reformers, including Philippe Pinel (1745-1826)) insisted that madness is not demon possession but a sickness of the mind caused by severe stresses and inhumane conditions. - For Pinel and others, “moral treatment” included things like boosting patient’s morale by unchaining them from these conditions and actually talking to them as if they were humans. - When researches found out that syphilis infected the brain and distorted the mind – they decided to find gradual reform. o Hospitals replaced asylums, and the medical world began searching for physical causes and treatments of medical disorders.

Biopsychosocial Approach: Assumes that biological. Socio-cultural, and psychological factors combine and interact to produce psychological disorders. ▯ **This approach recognizes that mind and body are inseparable. Classifying Psychological Disorders: - The American Psychiatric Association rendered a Diagnostic and Statistical Manual of Mental Disorders (DSM) to describe psychological disorders. - The most recent edition, DSM-IV-TR (Text Revision, 2000), describes 400 psychological disorders compared to 60 in the 1950s. ▯ How are psychological disorders diagnosed? ▯ ▯ ▯ Goals of DSM: 1. Describe (400) disorders. 2. Determine how prevalent the disorder is. -- Disorders outlined by DSM-IV are reliable. Therefore, diagnoses by different professionals are similar. -- Others criticize DSM-IV for “putting any kind of behavior within the compass of psychiatry.” Labeling Psychological Disorders: 1. Critics of the DSM-IV argue that labels may stigmatize individuals. 2. Labels may be helpful for healthcare professionals when communicating with one another and establishing therapy. 3. “Insanity” labels raise moral and ethical questions about how society should treat people who have disorders and have committed crimes. ▯ Anxiety Disorders: Feelings of excessive apprehension and anxiety. Types: 1. Generalized Anxiety Disorder 2. Panic Disorder 3. Phobias 4. Obsessive-Compulsive Disorder 5.
