Klinefelter's Syndrome with Tremors, Ataxia and Parkinsonism.

ABSTRACT

Klinefelter's syndrome (KS) is the most common cause of hypogonadism in men. Essential tremor (ET) and parkinsonism have been reported in KS, but ataxia, which has been commonly reported with other causes of hypogonadism, is very rare in KS. Orthostatic tremor has not been reported. We present a case with multiple movement disorders, including gait ataxia, essential-type tremor, rest tremor, orthostatic tremor and parkinsonism.
