Risperidone Reduces Symptoms in Children With Choreoathetoid Cerebral Palsy
Kernicterus, neonatal hypoglycemia, and perinatal asphyxia are a few causes of choreoathetoid cerebral palsy.
Risperidone significantly reduced the symptoms of abnormal movement and improved quality of life in children with choreoathetoid cerebral palsy (CP) and was well-tolerated, according to a study recently published in Pediatric Neurology.
Researchers treated a group of young patients with CP with risperidone for 1 year. Patients were enrolled at a teaching hospital in India, following parental consent. Of the initial 42 children, 35 met the study criteria, and 5 were excluded due to time missed for unrelated illnesses. The 30 children who completed 6 months of risperidone therapy had a mean age of 6.35 ± 3.17 years. In the study, the average dose of risperidone used was 0.75 mg, with a maximum dose of 2 mg/day. An equal number of boys and girls participated in the study.
Scores from the Abnormal Involuntary Movement Scale and Upper Extremity Skill Test (QUEST) were compared before and after treatment. In addition, a quality of life assessment—the CP-Quality Of Life questionnaire—was used. QUEST scores noted an increased ability to complete everyday tasks and showed significant improvements to participants' motor skills in their upper extremities. Researchers also note that better upper-body control improved quality of life for school-aged children.
Overall, the risperidone treatment had few side effects. Mild side effects such as drowsiness were reported early in the study, but the researchers found no serious side effects overall. The study also notes the benefits of risperidone in several areas: the ease of use and availability of the treatment, a positive impact on behavior in some cases, and fewer sleep disturbances among children in the study.
Researchers conclude that “[risperidone] is a promising drug to manage children with choreoathetoid [CP] and is well tolerated in children,” but also caution "these findings need to be interpreted cautiously and need further validation due to potential limitations of the study."
