Fragile X-associated tremor/ataxia syndrome difficult to diagnose

Fragile X-associated tremor/ataxia syndrome can be difficult to diagnose and should have guidelines for diagnostic testing, according to a study in the July 26 issue of Neurology, the scientific journal of the American Academy of Neurology. A second study found chemotherapy aggravated symptoms in one woman's case.
