Risperidone in non‐epileptic attack disorder and chromosome 15q deletion syndrome

Chromosome 15q11.2 microdeletion is an emerging syndrome identified in individuals with Prader‐Willi syndrome and Angelman syndrome but also found in isolation. Here, the authors present a case of a 19‐year‐old woman with chromosome 15q11.2 microdeletion and her successful treatment with risperidone, a tailored positive behaviour support plan and with staff training around non‐epileptic attack disorder.
