While there is currently no cure for FXS, there are many areas of treatment and intervention that can improve the lives of affected individuals and their families. Given the proper education, therapy, and support, all persons with Fragile X syndrome can make progress. The NFXF publishes Treatment Recommendations on treatments and interventions for Fragile X, written by and for professionals, with the understanding that they will be published online by the NFXF, read by caregivers, parents, and other family members (and in the case of some documents, by patients), and shared by those caregivers/parents/families/patients with their own care professionals. You can find all of them here and learn more about Fragile X syndrome here.
