A 52-year-old man is sent to see a psychiatrist after he is disciplined at his job because he consistently turns in his assignments late. He insists that he is not about to turn in anything until it is “perfect, unlike all of my colleagues.” He has few friends because he annoys them with his demands for “precise timelines” and because of his lack of emotional warmth. This has been a lifelong pattern for the patient, though he refuses to believe the problems have anything to do with his personal behavior. Which of the following is the most likely diagnosis for this patient?

a. Obsessive-compulsive disorder

b. Obsessive-compulsive personality disorder

c. Borderline personality disorder

d. Bipolar disorder, mixed state

e. Anxiety disorder not otherwise specified

the answer is below…

The United States Medical Licensing Examination, or USMLE for short, is a three-part licensing examination that is required in order to receive a license to practice medicine within the United States.

The USMLE assesses a physician’s ability to apply knowledge, concepts, and principles, and to determine fundamental patient-centered skills that are important in health and disease and that constitute the basis of safe and effective patient care. Examination committees composed of medical educators and clinicians from across the United States and its territories prepare the examination materials each year.

This exam is designed by the Federation of State Medical Boards and the National Board of Medical Examiners to determine whether or not an individual understands and can apply the knowledge necessary to practice medicine safely and intelligently.

The USMLE is actually comprised of three different exams that are referred to as steps, which examine the individual’s knowledge of specific topics related to the field of medicine such as basic science, medical knowledge, medical skills, clinical science, and the application of all of these skills and areas of knowledge in the medical field.

All three steps of the USMLE include a series of computerized multiple-choice questions, but the format of the exam and the information covered in each multiple-choice section is different for each step of the USMLE. The USMLE Step II also has a clinical skills portion that examines an individual’s ability to work with real patients and the USMLE Step III has a computerized patient simulation portion in addition to the multiple-choice section of the exam. In order for an individual to receive a license to practice medicine, the individual must pass all three steps of the USMLE.

Medical doctors with an M.D. degree are required to pass this examination before being permitted to practice medicine in the United States of America.

The correct answer is b.: Obsessive-compulsive personality disorder.[3]

The essential feature of obsessive-compulsive personality disorder is a preoccupation with perfection, orderliness, and control. Individuals with this disorder lose the main point of an activity and miss deadlines because they pay too much attention to rules and details and are not satisfied with anything less than “perfection.” As in other personality disorders, symptoms are ego-syntonic and create interpersonal, social, and occupational difficulties.

Obsessive-compulsive disorder is differentiated from obsessive-compulsive personality disorder by the presence of obsessions and compulsions. In addition, patients with symptoms of obsessive-compulsive disorder view them as ego-dystonic.

Patients with borderline personality disorder present with a history of pervasive instability of mood, relationships, and self-image beginning by early adulthood. Their behavior is often impulsive and self-damaging.

Patients with bipolar disorder present with problems of mood stability; mood may be depressed for several weeks at a time, then euphoric.

Patients with an anxiety disorder not otherwise specified present with anxiety as a main symptom, though they do not specifically fit any other, more specific anxiety disorder as per DSM-IV-TR.
