Types and causes of mental disorders Classification and epidemiology Psychiatric classification attempts to bring order to the enormous diversity of mental symptoms, syndromes, and illnesses that are encountered in clinical practice. Epidemiology is the measurement of the prevalence, or frequency of occurrence, of these psychiatric disorders in different human populations.
People with eating disorders take such concerns to extremes, developing abnormal eating habits that threaten their well-being and even their lives.
This question-and-answer fact sheet explains how psychotherapy can help people recover from these increasingly common disorders. What are the major kinds of eating disorders? There are three major types of eating disorders. Often refusing to eat, exercising compulsively, and developing unusual habits such as refusing to eat in front of others, they lose large amounts of weight and may even starve to death.
Often acting in secrecy, they feel disgusted and ashamed as they binge, yet relieved of tension and negative emotions once their stomachs are empty again. Like people with bulimia, those with binge eating disorder experience frequent episodes of out-of-control eating.
Anorexia and bulimia, for example, usually are preceded by very strict dieting and weight loss. Binge eating disorder can begin with occasional binging. Who suffers from eating disorders? According to the National Institute of Mental Health, adolescent and young women account for 90 percent of cases.
Older women, men and boys can also develop disorders. And an increasing number of ethnic minorities are falling prey to these devastating illnesses. People sometimes have eating disorders without their families or friends ever suspecting that they have a problem.
Aware that their behavior is abnormal, people with eating disorders may withdraw from social contact, hide their behavior and deny that their eating patterns are problematic.
Making an accurate diagnosis requires the involvement of a licensed psychologist or other appropriate mental health expert. What causes eating disorders? Certain psychological factors predispose people to developing eating disorders. Dysfunctional families or relationships are one factor.
Personality traits also may contribute to these disorders. Most people with eating disorders suffer from low self-esteem, feelings of helplessness and intense dissatisfaction with the way they look.
Specific traits are linked to each of the disorders. People with anorexia tend to be perfectionist, for instance, while people with bulimia are often impulsive. Physical factors such as genetics also may play a role in putting people at risk.
A wide range of situations can precipitate eating disorders in susceptible individuals. Family members or friends may repeatedly tease people about their bodies. Individuals may be participating in gymnastics or other sports that emphasize low weight or a certain body image.
Negative emotions or traumas such as rape, abuse or the death of a loved one can also trigger disorders. Once people start engaging in abnormal eating behaviors, the problem can perpetuate itself.
Binging can set a vicious cycle in motion, as individuals purge to rid themselves of excess calories and psychic pain, then binge again to escape problems in their day-to-day lives.
Why is it important to seek treatment for these disorders? Research indicates that eating disorders are one of the psychological problems least likely to be treated. And leaving them untreated can have serious consequences.
In fact, the National Institute of Mental Health estimates that one in ten anorexia cases ends in death from starvation, suicide or medical complications like heart attacks or kidney failure.
