Abstract:

Abstract Introduction Fragile X syndrome is an inherited form of mental retardation . It results from an abnormally expanded number of trinucleotide CGG repeats . Some grandfathers of these children become forgetful , have frequent falls and other neurological problems . Researchers have found a connection between fragile X syndrome and the neurological symptoms in elderly men . This resulted in the recognition of a syndrome originally referred to as “intention tremor , parkinsonism and generalised brain atrophy in carriers of a fragile X premutation” . This premutation is also associated with premature ovarian failure . Methodology This paper reviews the literature on the neurological signs of fragile X premutation . Conclusions Fragile X premutation is a risk for movement disorders and cognitive dysfunction and it should be considered in patients with a family history of mental retardation or autism , and particularly in those females with premature ovarian failure .
