A 28-year-old woman sees her physician with the chief complaint of a depressed mood. She also notes that she is sleeping more than usual—up to 14 hours per night—but does not feel rested and that she feels tired and fatigued all the time. She has gained 14 lb in the last month, something that she is very unhappy about, but she says that she seems to have such a craving for sweets that the weight gain seemed inevitable. Which of the following is the most likely diagnosis?

a. Mood disorder secondary to a general medical condition

b. Substance-induced mood disorder

c. Cyclothymia

d. Seasonal affective disorder

e. Dysthymic disorder

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 d; Seasonal affective disorder.[1]

Patients with seasonal affective disorder (SAD) typically present in just the way this patient has. Patients usually exhibit typical signs and symptoms seasonally, most often during the winter, with symptoms remitting in the spring. Hypersomnia and hyperphagia (atypical signs of a depression) are classically seen with this disorder. Light therapy and serotonergic agents (typically SSRIs) are the treatments of choice for this disorder.
