From the Research

Treatment for Fragile X syndrome should focus on a combination of non-pharmacological therapies and pharmacotherapy, with targeted treatments such as metformin, sertraline, and cannabidiol, as the most effective approach to managing symptoms and improving quality of life. According to the most recent study 1, a combination of non-pharmacological therapies and pharmacotherapy is currently the most effective treatment for FXS. The study highlights that targeted treatments, such as metformin, sertraline, and cannabidiol, can be used by clinicians to treat FXS.

Some key points to consider in the treatment of Fragile X syndrome include:

  • Medications such as SSRIs (e.g., sertraline 25-200 mg daily) can help with anxiety and mood problems, as suggested by a study on serotonin dysregulation in FXS 2
  • Stimulants (e.g., methylphenidate 5-60 mg daily) may address ADHD symptoms, as noted in a review of psychopharmacology in FXS 3
  • Atypical antipsychotics (e.g., risperidone 0.5-4 mg daily) might be prescribed for aggression or severe behavioral challenges, as discussed in a study on psychotropic drug treatment patterns in FXS 4
  • Therapy interventions, including speech therapy, occupational therapy, and behavioral therapy, are crucial for addressing problematic behaviors and improving communication skills, as emphasized in a review of FXS treatment 5
  • Special education services with individualized education plans (IEPs) and physical therapy may also be beneficial, as noted in the example answers

It is essential to prioritize early intervention and regular follow-ups with specialists to adjust treatments as needs change throughout development, as highlighted in the studies 1, 5. By taking a comprehensive and targeted approach to treatment, individuals with Fragile X syndrome can experience improved symptoms and quality of life.
