For Mr. A, Cushing’s disease presented as a psychiatric disorder with anxiety and insomnia that were resistant to numerous psychiatric medications during an 8-month period. If Mr. A’s PCP had not ordered a brain MRI, he may have continued to receive ineffective psychiatric treatment for some time. Many of Mr. A’s physical symptoms were consistent with Cushing’s disease and mental illness, including erectile dysfunction, fatigue, and muscle weakness; however, his 15-pound weight loss pointed more toward psychiatric illness and further disguised his underlying medical diagnosis, because sudden weight gain is commonly seen in Cushing’s disease (Table 24,5,7,9).
TREATMENT Persistent psychiatric symptoms, then finally relief
Four weeks after surgery, Mr. A’s psychiatric symptoms gradually intensify, which prompts him to see a psychiatrist. A mental status examination (MSE) shows that he is well-nourished, with normal activity, appropriate behavior, and coherent thought process, but depressed mood and flat affect. He denies suicidal or homicidal ideation. He reports that despite being advised to have realistic expectations, he had high hopes that the surgery would lead to remission of all his symptoms, and expresses disappointment that he does not feel “back to normal.”
Six days later, Mr. A’s wife takes him to the hospital. His MSE shows that he has a tense appearance, fidgety activity, depressed and anxious mood, restricted affect, circumstantial thought process, and paranoid delusions that his wife was plotting against him. He says he still is experiencing insomnia. He also discloses having suicidal ideations with a plan and intent to overdose on medication, as well as homicidal ideations about killing his wife and children. Mr. A provides reasons for why he would want to hurt his family, and does not appear to be bothered by these thoughts.
Mr. A is admitted to the inpatient psychiatric unit and is prescribed quetiapine, 100 mg every night at bedtime. During the next 2 days, quetiapine is titrated to 300 mg every night at bedtime. On hospital Day 3, Mr. A says he is feeling worse than the previous days. He is still having vague suicidal thoughts and feels agitated, guilty, and depressed. To treat these persistent symptoms, quetiapine is further increased to 400 mg every night at bedtime, and he is initiated on bupropion XL, 150 mg, to treat persistent symptoms.
After 1 week of hospitalization, the treatment team meets with Mr. A and his wife, who has been supportive throughout her husband’s hospitalization. During the meeting, they both agree that Mr. A has experienced some improvement because he is no longer having suicidal or homicidal thoughts, but he is still feeling depressed and frustrated by his continued insomnia. Following the meeting, Mr. A’s quetiapine is further increased to 450 mg every night at bedtime to address continued insomnia, and bupropion XL is increased to 300 mg/d to address continued depressive symptoms. During the next few days, his affective symptoms improve; however, his initial insomnia continues, and quetiapine is further increased to 500 mg every night at bedtime.
