Psychopharmaceutical treatment for neurobehavioral problems in Duchenne muscular dystrophy: a descriptive study using real-world data.

Patients with Duchenne muscular dystrophy (DMD) are at risk to develop neurobehavioral problems. Evidence on how to treat these difficulties is scarce. This descriptive study reports the clinical experience with psychopharmaceutical treatment in 52 patients with DMD. Electronic patient files were searched for patients with DMD that had been treated with psychopharmaceuticals between 2008 and 2022. Information about neurobehavioral symptoms, type of medication, side effects, and behavioral changes were collected. Two independent clinicians used the clinical global impression scale (CGI) to assess severity of the neurobehavioral problems before and the change in symptoms after treatment. Descriptive statistics were used. Our results include 52 males with DMD (mean age 11 years) treated with psychopharmaceuticals of which 55.8% had four or more comorbid neurobehavioral symptoms. The clinical condition was much improved on the GCI in 54.2% treated with methylphenidate, in 38.9% of the patients treated with fluoxetine, and in 22.2% treated with risperidone. Minimal effects and side effects were also reported. In conclusion, patients with DMD may experience severe neurobehavioral symptoms interfering with learning and/or development. Treatment with psychopharmaceuticals can improve these neurobehavioral symptoms, but further research is needed to gain better insights in psychopharmaceutical treatment in patients with DMD.
