TREATMENT: Trying risperidone
Based on case reports showing risperidone’s efficacy for catatonia, we start Ms. R on risperidone, 4 mg/d, and lorazepam, 4 mg/d. Eight days later, her catatonic symptoms decrease substantially—she scores 2/6 on the SCIP catatonia scale (Table)—and she starts to talk with the staff.
We continue this regimen for 30 days, then discontinue lorazepam to avoid long-term side effects—such as dependence—and titrate risperidone to 8 mg/d. Ms. R continues to improve while taking risperidone only. Twenty-three days after stopping lorazepam, she is free of catatonic symptoms, scoring 0/6 on the SCIP catatonia scale.
We discharge Ms. R on risperidone. Because she has a history of medication nonadherence, we prescribe risperidone long-acting injection, 37.5 mg every 2 weeks, while continuing oral risperidone for 3 weeks after the first injection. She does well on this medication, experiencing no catatonic symptoms or adverse effects over the next 15 months as measured by the SCIP assessment.
The authors’ observations
This is the third case report in the literature to show that risperidone is effective in short- and long-term treatment of catatonia.4,11 Although Ms. R’s initial response can be attributed at least partially to lorazepam—which is known to be effective in treating catatonia—she continued to show improvement while taking risperidone only and remained free from catatonic symptoms for 15 months, until she was readmitted for reasons unrelated to catatonia.
We recommend using risperidone to treat catatonia in patients who do not respond to a benzodiazepine, especially those with other psychotic symptoms such as delusions or hallucinations. While administering risperidone, watch for long-term side effects, such as hyperlipidemia, weight gain, and diabetes. For catatonia in patients who cannot tolerate risperidone, consider olanzapine or ziprasidone.
