There is no specific treatment for Fragile X syndrome. There are some medication under trial such as fenobam (mGLUR5 antagonist) and Lithium (mGLUR5 signaling inhibitor). Effort is directed toward training and education so that affected children can function at as high a level as is possible. Because the condition is not rare, specific educational approaches have been developed and tested.

While there is no current cure for the syndrome, there are several studies and researches going on for development of new therapies. Currently, the syndrome are treated with multi disciplinary approach which includes behavioral therapy, special education, medication, and physical rehabilitation. Persons with family histories of fragile x syndrome are advised to seek genetic counseling to assess the likelihood of having children who are affected.
