A 38-year-old male accountant is brought to the outpatient psychiatric clinic by his husband due to a 3-week history of worsening depressed mood, severe fatigue, and anhedonia. He reports sleeping up to 14 hours a day and has gained 5 kg (11 lbs) during this time. The patient states he feels completely hopeless and occasionally wishes he would not wake up in the morning, though he denies any active plan to end his life. When asked about unusual experiences, he mentions that over the past few days, he has occasionally heard his mother's voice calling his name just as he is drifting off to sleep. His psychiatric history is notable for an episode four years ago during which he felt "invincible" for 2 weeks. During that time, he slept only 3 hours per night, spoke incessantly, and impulsively spent his entire life savings on a high-risk cryptocurrency venture, resulting in personal bankruptcy. He was not hospitalized for that episode and currently takes no medications. Vital signs are within normal limits. Laboratory results show a thyroid-stimulating hormone (TSH) level of 1.5 µU/mL (normal: 0.4-4.0 µU/mL) and a free T4 of 1.1 ng/dL (normal: 0.8-1.8 ng/dL). Which of the following is the most appropriate next step in management?

  1. Initiate lithium therapyCevap
  2. B
    Initiate sertraline therapy
  3. C
    Initiate combination therapy with fluoxetine and phenelzine
  4. D
    Initiate haloperidol therapy for schizophreniform disorder
  5. E
    Initiate levothyroxine therapy

Cevap

The most appropriate next step in management is to initiate a mood stabilizer such as lithium.
This patient's history of a distinct 2-week period characterized by decreased need for sleep, grandiosity, pressured speech, and severe functional impairment (bankruptcy) meets the criteria for a manic episode. Therefore, his overarching diagnosis is Bipolar I disorder. He is currently presenting with a major depressive episode. The treatment of acute bipolar depression differs significantly from unipolar major depressive disorder. First-line pharmacotherapy for bipolar depression includes mood stabilizers (e.g., lithium) or specific second-generation antipsychotics (e.g., quetiapine, lurasidone, cariprazine). Lithium is highly effective for both treating the acute depressive episode and serving as a maintenance agent to prevent future manic and depressive relapses, as well as reducing the risk of suicide.

Adım Adım Çözüm

1
Analyze the patient's past psychiatric history.
The patient had a 2-week episode of decreased need for sleep, grandiosity, and reckless spending causing bankruptcy (marked impairment).
This confirms a history of a full manic episode, establishing the diagnosis of Bipolar I disorder.
2
Evaluate the current presentation and laboratory findings.
The patient is experiencing a major depressive episode. TSH and free T4 are normal, ruling out secondary or primary hypothyroidism. The auditory hallucination when falling asleep is a hypnagogic hallucination, which is benign.
This clarifies that the current state is acute bipolar depression and eliminates organic causes or primary psychotic disorders.
3
Select the appropriate pharmacotherapy for acute bipolar depression.
Lithium is selected over antidepressant monotherapy.
First-line agents for bipolar depression include lithium, quetiapine, lurasidone, or cariprazine. Standard antidepressants (SSRIs) must be avoided to prevent a manic switch.

Anahtar Kavram

Patients with a history of mania presenting with an acute depressive episode have Bipolar I disorder and must be treated with mood stabilizers or atypical antipsychotics approved for bipolar depression, strictly avoiding antidepressant monotherapy.
