Zorluk: OrtaPersonality Disorders

An occupational health physician evaluates a 24-year-old laboratory technician during a workplace assessment. The employee's supervisor requested the evaluation because the technician refuses to collaborate on team projects, stating that his coworkers possess 'disruptive energy fields.' During the interview, the technician avoids eye contact and speaks in a highly circumstantial and elaborate manner, frequently digressing to explain how atmospheric pressure changes alter human auras. Despite these eccentric beliefs, his speech remains logically connected, and he can be redirected to the main topic. He denies hearing voices, seeing things that others do not see, or believing that external forces are controlling his thoughts. A review of his history reveals that he has always been socially isolated and experiences intense anxiety around others that does not diminish with familiarity. His work performance in solitary tasks is excellent, and he has never experienced a major depressive or manic episode. Which of the following is the most likely diagnosis?

  1. Schizotypal personality disorderCevap
  2. B
    Schizophrenia
  3. C
    Schizophreniform disorder
  4. D
    Brief psychotic disorder
  5. E
    Schizoaffective disorder

Cevap

Schizotypal personality disorder
This patient exhibits classic features of a Cluster A personality disorder. Specifically, his presentation is consistent with schizotypal personality disorder, defined by a long-standing pattern of social deficits, acute discomfort with close relationships, cognitive or perceptual distortions (magical thinking regarding 'auras' and 'energy fields'), circumstantial speech, and excessive social anxiety that tends to be associated with paranoid fears rather than negative judgments about self. The absence of frank delusions, hallucinations, and discrete episodic timelines rules out primary psychotic disorders.

Adım Adım Çözüm

1
Analyze the patient's presenting symptoms and interpersonal behavior.
The patient demonstrates magical thinking ('disruptive energy fields', 'auras'), odd and circumstantial speech, social isolation, and severe social anxiety that does not improve with familiarity.
Identifying the cluster of odd and eccentric traits is necessary to categorize the psychiatric condition.
2
Evaluate for the presence of frank psychotic symptoms.
The patient explicitly denies auditory or visual hallucinations and lacks fixed, bizarre delusions or thought broadcasting. His speech is coherent and redirectable.
Ruling out true psychosis differentiates a personality disorder from primary psychotic disorders.
3
Assess the chronicity and timeline of the symptoms.
The traits have been present 'always' (lifelong history), representing an enduring pattern rather than an acute or subacute episodic change.
Personality disorders are characterized by pervasive, stable, and long-standing patterns of behavior starting by early adulthood, distinguishing them from illnesses defined by specific symptom durations (e.g., >6 months for schizophrenia).

Anahtar Kavram

Schizotypal personality disorder is characterized by a pervasive pattern of social and interpersonal deficits, marked by acute discomfort with close relationships, cognitive or perceptual distortions, and eccentricities of behavior, without frank psychosis.
