Medications in Fragile X

Treatment strategies for individuals with Fragile X Syndrome (FXS) are supportive, designed to maximize functioning. No treatments are available that specifically address the underlying neuronal defect caused by the absence of the Fragile X mental retardation protein. Because behavior in FXS can significantly impact functionality, symptom-based treatment of the individual’s most problematic behaviors can be quite helpful.

This article discusses:

  • Current medication management for behavior, including results of one study
  • Future possibilities for medication management

Medical Intervention in Fragile X Syndrome

Children and adults with Fragile X Syndrome often present to the physician with a variety of behavior problems. Because these problems are typical in Fragile X Syndrome, they are presumed to be caused by a lack or deficiency of normal FMR-1 protein (FMRP) production from the FMR-1 gene, which is dysfunctional in Fragile X Syndrome. FMRP normally is present in all neurons and its absence causes some changes in brain structure and function, and presumably changes in neurotransmitter systems that we can improve with medication. Although there is no cure for Fragile X Syndrome, medications can improve the behavior problems.

This article discusses medication related to:

  • Attention problems and hyperactivity
  • Mood fluctuations and/or aggressive outbursts
  • Anxiety or obsessive/compulsive behavior
