Mr. F says he is a “natural-born Bosnian gypsy translator,” and that he needs to finish “building the warehouse” with his father and grandfather (both are deceased). The nurses note that he is withdrawn, inactive, and suspicious; he spends most of the day lying in bed awake, and in the evening he paces in the hallway. Mr. F does not interact with other patients, is guarded when questioned, and does not eat much. He has minimal insight into his condition and says that he is at the hospital for “fevers and a cold,” “ESL treatment,” or because his “right side is thicker” than his left. It is unclear what Mr. F means by “ESL.” It may refer to English as a Second Language, given his apparent perseveration regarding his immigration status and language ability, but this is speculation.
TREATMENT Residual symptoms
With the additional collateral history and a negative medical workup, Mr. F meets DSM-5 criteria for acute, first-episode schizophrenia1 and is started on risperidone, 2 mg/d, titrated up to 2 mg twice daily, and trazodone, 50 mg, as needed, as a sleep aid. He shows significant improvement in his symptoms early in his treatment course. During visiting hours and at family meetings, he recognizes his wife, and during interviews he denies any continuing hallucinations. He initially says that he never failed to recognize his wife and kids, but later explains that he “woke up different…from a dream, and she was a different woman.” When asked specifically about hearing his father’s voice, he is uncertain, saying “No,” “I don’t know,” “I didn’t hear,” or “Not anymore.”
Despite his improvement, Mr. F continues to be disoriented and suspicious, and has minimal insight into his illness. He also continues to exhibit significant negative symptoms and cognitive impairment. Mr. F is withdrawn and has a flat affect, poverty of speech, delayed processing, and poor focus and attention.
On hospital Day 6, Mr. F reports feeling depressed. He misses his children and wants to go home. He has lost several pounds because he had a poor appetite and is now underweight. He is apathetic; interactions with staff and patients are minimal, he declines to attend group therapy sessions, and he still spends most of his time lying in bed awake or pacing the hallway. He also expresses a desire to quit smoking.
The authors’ observations
Despite its lack of specific inclusion in the DSM-5 criteria,1 cognitive impairment is a distinct, core, and nearly universal feature of schizophrenia. As demonstrated by Mr. F’s case, the severity of cognitive impairment in schizophrenia has no association with the positive symptoms of schizophrenia; it is a patient’s neurocognitive abilities—not the severity of his (her) psychotic symptoms—that most strongly predict functional outcomes.2
Neurocognitive impairment is a strong contributor to and predictor of disability in schizophrenia.3,4 Treatment of the cognitive symptoms of schizophrenia with antipsychotics has been largely ineffective.2 Effective drug therapy regimens are still being developed, and although there are some promising novel targets, no drug is FDA-approved to treat the cognitive symptoms of schizophrenia.2,4 However, it is known that additional treatment modalities, including social skills training and/or vocational rehabilitation, as well as treatment of comorbid conditions, may lead to improved cognitive status and, as a result, improved functional outcomes in schizophrenia.2-4
It is well documented that persons with schizophrenia in households with high expressed emotion (EE) have higher rates of relapse, independent of demographics and pharmacotherapy.5 EE is a measure of the family environment that evaluates how the relatives of a psychiatric patient spontaneously talk about the patient. Relatives are considered to have high EE if they show hostility or marked emotional overinvolvement, or if they make a certain number of critical comments. The tool used to measure EE is the Camberwell Family Interview Schedule.6,7 Rates of first-year relapse in high EE homes when family treatment is employed drop significantly, especially when combined with social skills training.8 The patient’s family members are educated about EE and its potential negative effects on the patient.
Cognitive remediation therapy (CRT) uses therapist-led, computer-based techniques to preserve intact neuroplasticity and has been shown to improve cognition and functional status, especially when paired with vocational rehabilitation or social skills training.2,3 Many trials confirm that CRT produces meaningful, durable improvements in cognition and functioning.3 One systematic review that focused on trials in early schizophrenia found that CRT had a significant effect on functioning and symptoms, and that these effects were larger when CRT was combined with adjunctive psychiatric rehabilitation and small group interventions.3
