Despite the inclusion of catatonia as a specifier of autism spectrum disorder in DSM-5, we—a team of child and adolescent neuropsychiatrists who specialise in paediatric catatonia and neurodevelopmental disorders—have identified a number of issues with the diagnosis and clinical management of catatonia in our patients.
Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by social communication deficits and restricted interests and behaviors which begin very early in life. In about a quarter of cases, the symptoms emerge about 18–24 months after a period of normal development, a phenomenon commonly described as early regression. However, marked functional decline can also occur in persons with autism after a relatively stable childhood.
This EL-PFDD meeting was modeled after the work of the FDA’s Patient Focused Drug Development (PFDD) initiative. PFDD is a systematic way of gathering patient perspectives on their condition and on available treatments. The information gathered at the meeting is presented in this Voice of the Patient report, a high-level summary of the perspectives generously shared by the families and caregivers of individuals living with PMS, who participated in the November 8, 2022, EL-PFDD meeting. The report also includes selected comments that were submitted through an online portal.

Phelan-McDermid syndrome is a genetic condition primarily caused by a deletion on the 22q13.3 region or a likely pathogenic/pathogenic variant of SHANK3. The main features comprise global developmental delay, marked impairment or absence of speech, and other clinical characteristics to a variable degree, such as hypotonia or psychiatric comorbidities.
Individuals with Phelan-McDermid syndrome caused by a 22q terminal deletion and a ring chromosome are at increased risk for Neurofibromatosis type 2 (NF2). However, the prevalence of NF2 in individuals with PMS and a r (22) is unknown.
