A 2323-year-old woman presents to the outpatient psychiatric clinic with a 22-month history of profound sadness, fatigue, and social withdrawal. She reports sleeping up to 1414 hours a day and experiencing a strong craving for carbohydrate-rich foods, leading to a 55-kg (1111-lb) weight gain. She states her arms and legs frequently feel "so heavy, it is as if my bones have turned to solid stone." Despite her depressed mood, she notes that she felt briefly happy and energized last week when she received a good grade on an exam, though the low mood quickly returned. She also reports occasionally hearing a voice calling her name just as she is drifting off to sleep. She has no chronic medical conditions. Vital signs are within normal limits. Laboratory studies reveal a thyroid-stimulating hormone (TSH) level of 1.8 \muU/mL1.8 \text{ \mu U/mL} (normal 0.5−5.0 \muU/mL0.5-5.0 \text{ \mu U/mL}) and free thyroxine (T4) of 1.2 ng/dL1.2 \text{ ng/dL} (normal 0.9−1.7 ng/dL0.9-1.7 \text{ ng/dL}). She is currently not taking any medications. She requests an antidepressant to help her focus on her studies. Which of the following is the most appropriate next step in the management of this patient?

  1. A
    Initiate monotherapy with sertraline
  2. B
    Diagnose schizophreniform disorder based on the duration of hallucinations
  3. Elicit a history of periods characterized by elevated mood, decreased need for sleep, and impulsivityCevap
  4. D
    Contact the patient's family to obtain collateral information regarding her depressive symptoms
  5. E
    Initiate levothyroxine supplementation for suspected secondary hypothyroidism

Cevap

Eliciting a history of periods characterized by elevated mood, decreased need for sleep, and impulsivity.
The correct response describes the process of screening for a history of manic or hypomanic episodes. This patient is experiencing a major depressive episode with atypical features (mood reactivity, hypersomnia, weight gain, leaden paralysis). Atypical features are highly prevalent in patients with bipolar depression. According to standard psychiatric guidelines, clinicians must explicitly rule out a lifetime history of mania or hypomania before initiating antidepressant monotherapy in any patient presenting with depression. Failure to do so can precipitate a manic switch, which is a psychiatric emergency.

Adım Adım Çözüm

1
Analyze the patient's clinical presentation.
The patient exhibits depressed mood, hypersomnia, hyperphagia, leaden paralysis (heavy limbs), and mood reactivity (brightening of mood in response to positive events).
Identifying the specific symptom cluster is necessary to classify the depressive subtype.
2
Establish the specific psychiatric syndrome.
The symptoms fulfill the DSM-5 criteria for a major depressive episode with atypical features.
Atypical features have distinct clinical implications, particularly a strong association with bipolar disorder.
3
Evaluate the reported hallucinations and laboratory findings.
The hallucinations occur only while falling asleep (hypnagogic) and are a normal physiological variant, ruling out a primary psychotic disorder. The TSH and T4 levels are normal, ruling out thyroid dysfunction.
It is necessary to exclude medical causes of depression and comorbid primary psychotic disorders before finalizing the management plan.
4
Determine the safest next step in management.
Before starting any antidepressant therapy, the clinician must screen for a history of manic or hypomanic episodes.
Prescribing an antidepressant (like an SSRI) to a patient with unrecognized bipolar disorder can precipitate a severe manic episode. Screening is mandatory.

Prior to initiating antidepressant therapy for a major depressive episode, clinicians must screen for a lifetime history of manic or hypomanic episodes to rule out bipolar disorder and prevent antidepressant-induced mania.
