Cluster A

  • Disorders: schizoid, schizotypal, and paranoid

  • Group similarities: eccentric, peculiar, or withdrawn

  • Mnemonic: "cluster Abnormal" (the weird)

  • Prevalence: 3.6%

  • Familial association: psychotic disorders. More common in biological relatives of patients with schizophrenia. Strongest correlation with schizotypal personality and less correlation with paranoid or schizoid personality.

Cluster B

  • Disorders: antisocial, borderline, histrionic, and narcissistic

  • Group similarities: emotional, dramatic, or inconsistent

  • Mnemonic: "cluster Bloated" (the wild)

  • Prevalence: 1.5%

  • Familial association: mood disorders. More common in biological relatives of patients with depression (particularly borderline personality) and substance use disorders (particularly antisocial personality). Additionally, a strong association is found between histrionic personality and somatic symptom disorders.

Question 2:

From day #130

Answer: c

SCHIZOID personality disorder

Explanation: 2

  • Individuals with schizoid personality disorder have a lifelong pattern of social withdrawal and are often perceived as eccentric and reclusive.

  • The adjective "schizoid" was originally coined to describe the prodromal seclusiveness and isolation observed in schizophrenia, however the schizoid personality type was made official in DSM-3 in 1980.

  • They tend to be uncomfortable with human interaction and often display a bland and constricted emotional affect. They have no desire for close relationships and prefer to be alone.

  • Common traits/symptoms may include being -> quiet, reclusive, unsociable, isolated, eccentric, aloof, blunted, disengaged, and distant.

  • Incorrect answers: schizotypal PD have more eccentric behaviors and magical thinking. The social isolation of schizoid PD can be distinguished from that of avoidant PD, which is attributable to fear of being embarrassed and excessive anticipation of rejection. Unlike with avoidant PD, patients with schizoid PD prefer to be alone. Individuals with obsessive-compulsive PD may also show an apparent social detachment, however this stems from devotion to work and discomfort with emotions rather than a lack of desire and capacity for intimacy. Antisocial PD individuals have a long-standing pattern of rule-breaking, exploiting others without remorse, and disregarding the rights and safety of others.
