A 31-year-old man is evaluated in the clinic due to a one-month history of overwhelming sadness, severe fatigue, and a loss of interest in his usual hobbies. During this time, he has been sleeping up to 12 hours a day and has missed multiple days of work. His wife, who accompanies him, reports that four years ago he experienced a distinct two-week period where his behavior changed dramatically. During that time, he slept only two hours a night without feeling tired, obsessively pursued a chaotic new business venture, and spoke so rapidly that others could not interrupt him. He was not hospitalized during that episode and eventually returned to his baseline. He is currently taking no medications, and his medical history is unremarkable. Which of the following is the most appropriate pharmacologic intervention for this patient's current symptoms?

  1. A
    Sertraline
  2. B
    Bupropion
  3. LurasidoneCevap
  4. D
    Fluoxetine and phenelzine
  5. E
    Venlafaxine

Cevap

Lurasidone
The patient is currently experiencing a major depressive episode, but his history of a distinct period of decreased sleep, pressured speech, and excessive goal-directed behavior confirms a prior manic episode. Therefore, his diagnosis is bipolar I disorder, currently in a depressed episode. Lurasidone is an atypical antipsychotic that is FDA-approved and widely recommended as a first-line treatment for acute bipolar depression. It provides necessary antidepressant effects without the risk of triggering a manic switch.

Adım Adım Çözüm

1
Identify the patient's current clinical syndrome.
The patient has a one-month history of depressed mood, anhedonia, fatigue, and hypersomnia, fulfilling the criteria for a major depressive episode.
Establishing the current affective state is necessary to understand the immediate treatment target.
2
Evaluate the patient's psychiatric history for previous mood episodes.
The patient has a history of a two-week period characterized by decreased need for sleep, pressured speech, and goal-directed activity, which meets the criteria for a past manic episode.
A history of mania changes the diagnosis from major depressive disorder (unipolar depression) to bipolar I disorder, profoundly altering the treatment algorithm.
3
Select the appropriate pharmacotherapy for acute bipolar depression.
Lurasidone is chosen because it is an effective, first-line agent for bipolar depression.
Antidepressant monotherapy must be avoided in bipolar disorder to prevent the induction of a manic switch.

Anahtar Kavram

Patients presenting with depressive symptoms must be carefully screened for a history of mania; bipolar depression should be treated with mood stabilizers or specific atypical antipsychotics (e.g., lurasidone, quetiapine), strictly avoiding antidepressant monotherapy.
