Narcissistic personality disorder: pervasive pattern of superior grandiosity, need for admiration, and a perceived or real lack of empathy. In a more severe expression, narcissistic personality disorder may show evidence of paranoia, aggression, psychopathy, and sadistic personality disorder, which is known as malignant narcissism. Cluster C (anxious or fearful disorders)
Avoidant personality disorder: pervasive feelings of social inhibition and inadequacy, extreme sensitivity to negative evaluation. Dependent personality disorder: pervasive psychological need to be cared for by other people. Obsessive–compulsive personality disorder: characterized by rigid conformity to rules, perfectionism, and control to the point of satisfaction and exclusion of leisurely activities and friendships (distinct from obsessive–compulsive disorder). DSM-5 general criteria
Both the DSM-5 and the ICD-11 diagnostic systems provide a definition and six criteria for a general personality disorder. These criteria should be met by all personality disorder cases before a more specific diagnosis can be made. In DSM-5, any personality disorder diagnosis must meet the following criteria:
An enduring pattern of inner experience and behavior that deviates markedly from the expectations of the individuals culture. This pattern is manifested in two (or more) of the following areas:
Cognition (i.e., ways of perceiving and interpreting self, other people, and events). Affectivity (i.e., the range, intensity, lability, and appropriateness of emotional response). Interpersonal functioning. Impulse control. The enduring pattern is inflexible and pervasive across a broad range of personal and social situations. The enduring pattern leads to clinically significant distress or impairment in social, occupational, or other important areas of functioning.
DSM-5
The most recent fifth edition of the Diagnostic and Statistical Manual of Mental Disorders stresses that a personality disorder is an enduring and inflexible pattern of long duration leading to significant distress or impairment and is not due to use of substances or another medical condition. The DSM-5 lists personality disorders in the same way as other mental disorders, rather than on a separate axis, as previously.DSM-5 lists ten specific personality disorders: paranoid, schizoid, schizotypal, antisocial, borderline, histrionic, narcissistic, avoidant, dependent and obsessive–compulsive personality disorder. The DSM-5 also contains three diagnoses for personality patterns not matching these ten disorders, but nevertheless exhibit characteristics of a personality disorder:
Personality change due to another medical condition – personality disturbance due to the direct effects of a medical condition. Other specified personality disorder – general criteria for a personality disorder are met but fails to meet the criteria for a specific disorder, with the reason given. Unspecified personality disorder – general criteria for a personality disorder are met but the personality disorder is not included in the DSM-5 classification.These specific personality disorders are grouped into the following three clusters based on descriptive similarities:

Cluster A (odd or eccentric disorders)
Cluster A personality disorders are often associated with schizophrenia: in particular, schizotypal personality disorder shares some of its hallmark symptoms with schizophrenia, e.g., acute discomfort in close relationships, cognitive or perceptual distortions, and eccentricities of behavior. However, people diagnosed with odd-eccentric personality disorders tend to have a greater grasp on reality than those with schizophrenia.
