Aberrant Face and Gaze Habituation in Fragile X Syndrome

In the present study, we investigated neural system habituation to eye gaze in individuals with fragile X syndrome compared with individuals group-matched for sex, intellectual functioning, autism symptoms, and adaptive behavior. Our primary result reveals less neural habituation in individuals with fragile X syndrome in response to all facial stimuli (direct gaze + averted gaze), […]

fragile x associated tremors/ataxia syndrome

_ Fragile X–associated tremor/ataxia syndrome (FXTAS) is a genetic disorder affecting mostly men and causing tremor, ataxia, and dementia. FXTAS affects about 1/3000 men. A premutation (an increased number of CGG repeats) occurs in the fragile X mental retardation (FMR1) gene on the X chromosome; if the mutation is full, > 200 repeats occur, causing […]
