A 22-year-old man presents to the psychiatry clinic complaining of profound fatigue, poor concentration, and severe sleep disturbances. Five weeks ago, he was held at gunpoint during a convenience store robbery. Since the incident, he has experienced recurrent nightmares about the event, actively avoids the neighborhood where the store is located, and feels constantly "on edge." He also describes distressing periods where he feels as though he is floating outside of his own body. His past medical history is significant for a major depressive episode at age 19. At that time, he was prescribed fluoxetine; however, within two weeks of starting the medication, he developed a severe episode of elated mood, pressured speech, and a decreased need for sleep that lasted for eight days. The fluoxetine was discontinued, and he subsequently stabilized. He also reports a separate episode two years ago during which he heard voices telling him he was special; this lasted for three weeks and resolved entirely without treatment. The patient admits that due to his recent severe distress, he restarted taking leftover fluoxetine from his old prescription three days ago. He is requesting additional medication to help him cope. Which of the following is the most appropriate next step in the management of this patient's current condition?

A 28-year-old woman presents to the emergency department reporting a sudden onset of intense chest pain, palpitations, shortness of breath, and a feeling of impending doom that began 20 minutes ago while she was resting at home. She states, "I thought I was having a heart attack and going to die." This is her fourth similar episode this month. She is now terrified of having another attack and has stopped driving to work out of fear of losing control. Her medical history is notable for a severe depressive episode two years ago. At that time, she was started on citalopram, but within days she developed racing thoughts, a decreased need for sleep, and impulsive spending, which led to her hospitalization. She currently takes no medications. Her temperature is 37.0°C (98.6°F), blood pressure is 128/82 mm Hg, pulse is 110/min, and respirations are 22/min. Physical examination, ECG, and serial cardiac troponins are unremarkable. The patient's acute symptoms resolve completely after reassurance in the emergency department. Which of the following is the most appropriate long-term management strategy for this patient's current psychiatric condition?

A 32-year-old architect is evaluated in the clinic for worsening sadness and inability to concentrate at work over the past month. He reports sleeping up to 14 hours a day and feeling completely drained of energy. He has a history of an emergency department visit 4 years ago when he was brought in by his family for not sleeping for 6 days, talking rapidly, and spending a large portion of his savings on impulsive online purchases while claiming he had a foolproof plan to become a billionaire. He was hospitalized and stabilized at that time but stopped all medications 2 years ago. His vital signs are within normal limits. Physical examination shows no focal neurologic deficits and normal thyroid gland palpation.

A 28-year-old woman is brought to the psychiatric outpatient clinic by her husband due to profound sadness, hypersomnia, and a 4.5-kg (10-lb) weight gain over the past 4 weeks. She reports feeling "slowed down" and states that she has begun hearing a voice repeatedly telling her she is worthless. Review of her medical history reveals that 2 years ago, she experienced a distinct 2-week period where she slept only 2 hours a night without feeling fatigued, spent their entire savings on luxury vehicles, and claimed she could communicate directly with angels; this episode required hospitalization. Her current medications include isocarboxazid, which was prescribed 2 weeks ago by a different physician for her depression. Vital signs are within normal limits. Physical examination shows a depressed affect and psychomotor retardation. Laboratory studies show a free thyroxine (T4) level of 0.5 ng/dL (normal: 0.9–1.7 ng/dL) and a thyroid-stimulating hormone (TSH) level of 1.5 µU/mL (normal: 0.5–5.0 µU/mL).

A 35-year-old man is brought to the clinic by his husband for couples counseling. The husband complains that the patient is "suffocatingly rigid." For example, the patient insists on packing the dishwasher in a highly specific configuration and will unpack and repack it entirely if the husband does it "incorrectly." The patient recently received a formal warning at his accounting firm because he missed a major filing deadline; he spent three weeks formatting the spreadsheets to look "flawless" rather than submitting the adequate, finalized data on time. He refuses to delegate tasks to junior accountants, stating, "They are careless, and I am the only one who can do it exactly right." He frequently skips social events to organize his home office and refuses to throw away old, broken electronics, claiming they "might be useful someday." During the interview, the patient appears frustrated and says, "My husband is overreacting. I just have high standards. Is it a crime to want things done properly?" He denies any repetitive, intrusive thoughts or sudden urges that cause him distress. Mental status examination reveals a constricted affect and overly formal speech.

A 32-year-old woman comes to the outpatient clinic 4 months postpartum for a follow-up evaluation of depressive symptoms. Two weeks ago, she presented with a 4-week history of profound despondency, early morning awakenings, anorexia with a 3-kg (6.6-lb) weight loss, and feeling worse in the morning. She reported that these symptoms made it exceedingly difficult to get out of bed and properly care for her infant. At that time, she was diagnosed with major depressive disorder and started on escitalopram 10 mg daily. Today, she states, "The medication isn't working. I still feel incredibly depressed, but now I also feel extremely restless, jittery, and my thoughts are racing." Vital signs are within normal limits. On examination, the patient appears visibly agitated, is pacing the room, and exhibits rapid speech. Upon detailed psychiatric review, she mentions that during her second year of college, she experienced a spontaneous 6-day period where she felt "incredibly energized," slept only 3 hours per night without fatigue, and impulsively maxed out two credit cards on unnecessary clothing.

Match each distinct clinical presentation of a breast disorder to its most likely diagnosis.

A 28-year-old man is evaluated on the inpatient medical floor where he is being treated for a severe asthma exacerbation. The nursing staff reports that his behavior has been highly disruptive. During the morning shift, he told his assigned nurse that she is "the most compassionate and skilled caregiver in this entire hospital." However, later in the afternoon, he became enraged with a different nurse, yelling that she is "cruel, incompetent, and intentionally ignoring me." When the attending physician informs the patient that his respiratory status has improved and he will be discharged the following day, the patient becomes visibly furious. He threatens to stop taking all his asthma medications and walk into oncoming traffic if he is forced to leave.

A 34-year-old woman presents to the clinic accompanied by her sister due to a 4-week history of recurrent, unexpected episodes of intense fear, palpitations, sweating, and chest pain. Each episode peaks within 10 minutes. Because of these attacks, she has stopped going to work and refuses to leave her house, fearing she will be unable to escape if an attack occurs. She has a history of bipolar I disorder, diagnosed after a severe manic episode at age 24, but discontinued her lithium 3 years ago. For the past month, she has also felt profoundly sad, with low energy and hypersomnia. She recently saw another physician who prescribed phenelzine two weeks ago.

A 45-year-old male executive presents to the primary care clinic reporting a two-month history of having "zero energy." He describes experiencing a persistently low mood, an inability to enjoy his usual hobbies, and a sensation that his arms and legs are unusually heavy. The patient reports sleeping 12 to 14 hours a day and has gained 7 kg (15.4 lb) over this period. Medical history is notable for migraine headaches, for which he takes sumatriptan as needed; he has used it twice in the past week. Four years ago, the patient experienced a distinct six-day period during which he slept only two hours a night but felt completely rested. During that time, he was highly talkative, unusually confident, and impulsively invested a large amount of money into a risky startup. This caused significant marital friction but did not require hospitalization. Vital signs are within normal limits. Mental status examination reveals psychomotor retardation and a blunted affect, but no delusions or suicidal ideation. Laboratory studies show a thyroid-stimulating hormone (TSH) level of 1.8 µU/mL (normal: 0.5–5.0 µU/mL) and free T4 of 1.1 ng/dL (normal: 0.8–1.8 ng/dL).

Match each clinical presentation to the most likely underlying neurocognitive etiology.

A 24-year-old woman presents to the emergency department after sustaining superficial lacerations to her left forearm. Her roommate brought her in, stating the patient became deeply distraught after a man she had been dating for two weeks did not immediately reply to a text message. The patient tearfully explains she felt "completely hollow and abandoned." During the initial triage, the patient tells the nurse, "You are the only person who actually listens to me; everyone else here is heartless." Thirty minutes later, when the attending physician suggests a psychiatry consultation before discharge, the patient throws a cup of water at the wall and screams, "You are an incompetent, cruel doctor trying to lock me up!" The roommate notes that the patient has a history of impulsive spending sprees, frequent binge eating, and a chronically unstable mood. The patient is currently taking paroxetine for depressive symptoms. She asks the physician to prescribe tranylcypromine, stating that a friend takes it and it "works wonders for mood swings."
