We are excited to share journal publications like this one resulting from FORWARD data. There are many more papers currently in development, and the future for Fragile X syndrome research is bright as more data is gathered.

Behavioral dysregulation, or the impairment of behavioral processes, is common in Fragile X syndrome. A regularly cited group of behaviors in individuals with FXS, particularly males, is irritability, agitation, aggression, and self-injury (IAAS). These behaviors can put a strain on both the individual and their caregiver’s quality of life and there is little information about how to manage these behaviors with medication.

This publication in the Journal of Autism and Developmental Disorders presented information from a FORWARD dataset involving 415 individuals with IAAS behaviors. The study describes the psychopharmacologic management of IAAS and examines the characteristics of individuals that are treated with drug therapy for IASS.

Findings showed that among the individuals with FXS that were exhibiting IAAS, those receiving drug treatment were more likely to be older males with significant intellectual disability. The individuals receiving drug treatment were also more likely to have comorbid autism, anxiety, hyperarousal, and social impairment. The medications most used in this population are antipsychotic medications, particularly aripiprazole and risperidone, both of which are FDA-approved for treating irritability associated with ASD. Individuals were also prescribed drugs outside of antipsychotic medications, including selective serotonin reuptake inhibitors (SSRIs), stimulants, non-SSRI antidepressants, alpha-agonists, mood-stabilizers, and anxiolytics. Most individuals (63%) did not experience side effects from their drug treatment.

Why This is Important

This study contributes to the limited understanding of psychopharmacologic management of IAAS in FXS and will help guide future treatment.

What Are the Next Steps

A deeper analysis of long-term drug treatment of various target symptoms, more specific evaluation of each behavior within the IAAS symptom category, and more extensive analysis of drug tolerability over time.

FORWARD is made possible by all the participating families sharing their life experiences for research. By giving families, doctors, scientific researchers, and policymakers an inside look into how Fragile X syndrome presents itself across the human lifespan, you’re involvement is a huge contribution toward more positive health outcomes and better care and services for future generations.
