Difficulty: MediumSubstance-Related and Addictive Disorders

A 20-year-old man is brought to the emergency department by his college roommate due to profound fatigue, severe depressed mood, and increased appetite for the past two days. The roommate reports that last week, the patient was awake for four consecutive days preparing for final exams. During that time, the patient was highly energetic, unusually talkative, and told his roommate he had "unlocked the mathematical secrets of the universe." The patient now sleeps up to 16 hours a day and complains of intensely vivid, disturbing dreams when he briefly awakens. He has no prior medical or psychiatric history and takes no prescribed medications. Vital signs are temperature 36.8°C (98.2°F), blood pressure 112/72 mm Hg, pulse 58/min, and respirations 14/min. Physical examination shows a flat affect and significant psychomotor retardation, but no focal neurological deficits. Which of the following is the most appropriate next step in management?

  1. A
    Initiate citalopram therapy
  2. B
    Administer empiric intravenous ceftriaxone and vancomycin
  3. Provide supportive care and observationAnswer
  4. D
    Initiate risperidone therapy
  5. E
    Notify the patient's family about the suspected substance use

Answer

Provide supportive care and observation
The correct next step in management is to provide supportive care and observation. This patient is exhibiting a classic presentation of stimulant (e.g., amphetamine or cocaine) withdrawal. The initial phase of prolonged wakefulness, excessive energy, and grandiosity represents acute stimulant intoxication, commonly seen in college students abusing "study drugs." The abrupt cessation of the stimulant leads to a "crash," which is characterized by profound fatigue, hypersomnolence, hyperphagia, intense and vivid unpleasant dreams, and severe depression with psychomotor retardation. Unlike alcohol or benzodiazepine withdrawal, stimulant withdrawal is not acutely life-threatening and does not require specific substitution pharmacotherapy or tapering protocols. The most appropriate management is supportive care, allowing the patient to rest and recover while monitoring closely for severe depressive symptoms or suicidal ideation.

Step-by-Step Solution

1
Analyze the biphasic clinical presentation based on the history.
The patient had a period of prolonged wakefulness, hyperactivity, and grandiosity (intoxication), followed by a "crash" of hypersomnolence, hyperphagia, vivid dreams, and psychomotor retardation (withdrawal).
Recognizing the transition from acute intoxication to withdrawal is essential for identifying substance-related syndromes, specifically stimulant abuse.
2
Determine the appropriate intervention for the current state (stimulant withdrawal).
Stimulant withdrawal relies primarily on supportive care, as there are no FDA-approved targeted pharmacotherapies to reverse or treat the withdrawal syndrome.
Unlike alcohol or sedative withdrawal, stimulant withdrawal is not generally life-threatening, making supportive observation the safest and most effective initial step.

Key Concept

Stimulant withdrawal typically presents with a "crash" characterized by severe fatigue, hypersomnolence, hyperphagia, vivid unpleasant dreams, and depression following a period of high energy and prolonged wakefulness. Management is primarily supportive.
