Ch 11: Psychological Disorders and Health

About This Chapter

Take a look at how psychological disorders are diagnosed; learn about the symptoms and causes of all the major disorders including depression, schizophrenia and obsessive compulsive disorder. Consider the unique challenges of diagnosing mental disorders compared to physical disorders.

Introductory Psychology: Psychological Disorders and Health

Though many psychologists study the workings of the healthy mind, there are some who devote themselves to studying and treating patients suffering from disordered patterns of thinking and feeling. These psychologists are known as clinical psychologists. Along with psychiatrists, social workers and therapists, psychologists discover and implement the best ways to diagnose and treat psychological disorders.

We begin by defining disorders and the evolution of the diagnostic process. These are important frames for understanding the disorders we cover in detail in subsequent videos. A disorder is defined as a pattern of abnormal thought or behavior or as the mind's normal mechanisms gone wrong. These disorders often result in stress, and can sometimes even prevent normal functioning in everyday life.

Clinical psychologists and other mental health professionals use the Diagnostic and Statistical Manual (DSM) to take down their patients' symptoms and reach a diagnosis. The DSM is a work in progress, updated periodically to reflect changes in classification of disorders. Regardless of the disorder, the DSM doesn't give any recommendations for treatment; it's purely intended to aid in diagnosis.

Psychological disorders can have many causes, so treatment often depends on a variety of factors. The majority of the lessons in this topic outline the major classes of disorders and their potential causes. Some lessons cover disorders that might be familiar to you. In one video, we'll cover depression and other mood disorders, and in another we'll cover the psychotic disorder schizophrenia. Other lessons may seem less familiar, like the one on somatoform disorders, in which serious physical symptoms are produced entirely by the brain. You might be surprised to find videos on substance abuse and eating disorders listed under psychological disorders. But if we look back to our definition of disorder, we can see why all of these are grouped together: they're all characterized by negative patterns of thought or behavior.

With this series of video lessons and quizzes, we aim to demystify the subject of mental health. We hope you come away with a better understanding of the causes and symptoms of psychological disorders, but also of the unique difficulties involved in diagnosing them.
