Difficulty: Very hardAnxiety, OCD, and Trauma-Related Disorders

A 28-year-old man presents to the outpatient psychiatric clinic complaining of severe "panic attacks" and insomnia. For the past 8 months, he has experienced sudden surges of intense fear accompanied by tachycardia, diaphoresis, and a feeling of impending doom. These episodes are frequently triggered by loud noises or when he attempts to fall asleep. During these episodes, he reports "zoning out" and vividly hearing the screeching of tires and feeling the impact of a vehicle, reliving a severe car accident he survived 8 months ago in which his fiancée was killed. He has since refused to ride in any motor vehicles, walking 3 miles to work every day. He notes that 3 years ago, he experienced a distinct 4-week period where he required only 2 hours of sleep per night, believed he had been chosen by God to solve world hunger, and maxed out multiple credit cards to start a charity. This behavior led to a brief psychiatric hospitalization, but he stopped taking his prescribed medications shortly after discharge. He is currently taking no medications. Vital signs, physical examination, and laboratory studies are unremarkable. Which of the following is the most appropriate next step in management?

  1. A
    Initiate sertraline monotherapy
  2. B
    Initiate citalopram and phenelzine
  3. Initiate valproate and trauma-focused cognitive behavioral therapyAnswer
  4. D
    Initiate haloperidol monotherapy for schizophrenia
  5. E
    Initiate alprazolam and mandate a report to the Department of Motor Vehicles

Answer

The most appropriate next step is to initiate a mood stabilizer (such as valproate) and trauma-focused cognitive behavioral therapy.
The correct approach for a patient presenting with active Post-Traumatic Stress Disorder (PTSD) and a clear history of Bipolar I Disorder (evidenced by his prior hospitalization for severe mania) is to initiate a mood stabilizer alongside an evidence-based psychotherapy. Trauma-focused cognitive behavioral therapy (TF-CBT) is the gold standard for PTSD and carries no risk of mood destabilization. Concurrently, valproate provides necessary mood stabilization to prevent future manic episodes and establishes a safe baseline should pharmacological PTSD treatments become necessary later.

Step-by-Step Solution

1
Diagnose the current presenting symptom cluster.
The patient meets criteria for Post-Traumatic Stress Disorder (PTSD).
He has a history of severe trauma (>1 month ago), intrusive symptoms (dissociative flashbacks), avoidance (refusing to ride in cars), and hyperarousal (insomnia, panic-like surges).
2
Analyze the patient's psychiatric history.
The patient has a definitive history of Bipolar I Disorder.
He previously experienced a 4-week episode of decreased need for sleep, grandiosity, and reckless spending that required psychiatric hospitalization (a classic manic episode).
3
Evaluate treatment options for comorbid PTSD and Bipolar I Disorder.
Antidepressant monotherapy must be avoided.
Using an SSRI or SNRI without a concurrent mood stabilizer in a patient with Bipolar I Disorder carries a high risk of inducing a severe manic episode (manic switch).
4
Select the safest comprehensive management plan.
Initiate a mood stabilizer and trauma-focused psychotherapy.
Valproate stabilizes the underlying bipolar disorder, while trauma-focused cognitive behavioral therapy provides gold-standard, non-pharmacologic treatment for the PTSD symptoms.
