Tremor and Klinefelter's Syndrome.

Abstract

BackgroundKlinefelter’s syndrome (KS) has been associated with tremor, but reports on tremor phenomenology and treatment are limited.Case ReportsPatient 1 is a 17-year-old male with a dystonic tremor treated with deep brain stimulation (DBS). Patient 2 is a 57-year-old male with a predominant left hand resting tremor and dystonic features.DiscussionOur cases suggest that the tremor in patients with KS may be dystonic in nature. Patient 1 is also the third reported case of successful treatment with DBS. These cases have implications for elucidating the underlying neurobiological mechanism of tremor and identifying treatment options.
