Pathophysiology Criteria Neurocognitive And Disorders Practice Test

In this question, the idea is to recognize how personality disorders are grouped into clusters that reflect similar patterns of behavior. Cluster B is the dramatic, emotional, and erratic group, and it includes antisocial, borderline, histrionic, and narcissistic personality disorders. The option described as dependent personality disorder does not fit that cluster; it belongs to Cluster C, which is characterized by anxious or fearful behaviors. Dependent personality disorder involves a pervasive pattern of submissiveness and clinging to others, with a strong need to be cared for, difficulty making autonomous decisions, and distress when alone or when relationships end. This contrasts with the Cluster B patterns: antisocial involves disregard for others’ rights; borderline features intense instability in mood and relationships; histrionic shows excessive emotionality and attention-seeking; narcissistic involves grandiosity and a need for admiration. Because dependent personality disorder aligns with uncertainty, fear of separation, and reliance on others, it is not a Cluster B disorder.
