There is a branch of psychology that is primarily focused on studying unusual patterns of behavior, emotion and thought. This subdivision of psychological science is also known as abnormal psychology. The abnormal psychology deals with the distinctions of normal and abnormal in such a way, as they are not synonymous with good or bad. Abnormal psychology rather examines the instances where falling outside of the norms can be good or a bad thing, normal or abnormal.
Psychological disorders are thus defined as patterns of behavioral or psychological symptoms that affect multiple areas of life. Personality disorders are pervasive chronic psychological disorders, which can greatly affect a person's life. Personality disorders can be mild or more severe in terms of how pervasive and to what extent a person exhibits the features of a particular personality disorder.
