A psychological disorders are conditions known by abnormal thoughts, speech, feelings, and behaviors. Psychopathology is the in depth knowledge of psychological disorders, including an understanding of the disorders, their causes, and treatment. The word psychopathology can also refer to the predictable indications of psychological disorders. Although opinions can be different, it is most important for mental health specialist to agree on what kinds of thoughts, words, feelings, and behaviors are actually abnormal in the manner that they truly proof the presence of psychopathology. Certain forms of behavior and inner thoughts, experiences can easily be thought of as abnormal and surely signify some kind of psychological psychopathology. An individual who washes his hands 40 times per day and the person who claims to hear the voices of Satan or demons acts, behaves and with inner experiences that most people would see it as abnormal: thoughts, beliefs and behaviors that suggest the existence of one or more psychological disorders. But, we can consider the nervousness of a young woman who feels nervous when talking to attractive men or the loneliness and missing home a freshman experiences during his first year of college, these feelings may not represent a psychological disorder, but if they are or become on going and chronic then they might fall in the range of abnormal. So, what kinds of thoughts, speech, feelings, and behaviors represents true psychological disorders? Psychologists work hard to find the difference between psychological disorders that come from inner experiences and behaviors than the ones that are just situational, or sometimes peculiar, or unconventional.


Maybe the simplest way to understand psychological disorders is to label actions, thoughts, words, and inner experiences that are atypical, extremely different, distressful, dysfunctional, and sometimes even fatal, as signs of a psychological disorder. For example, one asks a classmate for a date and he or she is rejected, one might probably feel a little rejected. These types of feelings would be considered normal. If one felt extreme depression, so much that would lose all interest in activities, also would have difficulty eating and sleeping, felt worthless, and would even consider suicide, those extreme reaction to rejection would be abnormal, atypical, and could give clear evidence of the presence of a psychological disorder. Just because something is not normal, it may not necessarily mean it is disordered.

As an example, only about four percent of people in the United States of America have red color hair, so red colored hair is considered an atypical hair color, but it is not thought of as disordered, yes it is unusual, but not abnormal. As one may learn, some psychological disorders, although not exactly typical,but the rates in which they appear in the population are surprisingly high. One cannot and should not jump to conclusions if someone seems different, that is why one needs to seek the expertise of psychotherapist to get to the truth.
