title: Behr syndrome variant with tremor treated by VIM stimulation.
abstract: Behr syndrome was first described in 1909 as a syndrome of heredofamilial optic atrophy, visual disturbances, nystagmus, and variable pyramidal tract signs. The syndrome has been reported in both sexes. So far, tremor has not been reported to be part of Behr Syndrome. We present the case of a 51-year-old man with a rare complicated dominant inherited cerebellar ataxia with accompanying visual loss and tremor (CICALVT) resembling a Behr Syndrome variant who suffered from advanced visual deterioration since childhood and progressive spastic paraparesis for 15 years. Furthermore, the patient presented increasing tremor of both hands for 5 years. The successful treatment of the tremor using deep brain stimulation (DBS) of the ventral intermediate thalamic nucleus (VIM) is reported. Our case indicates that deep brain stimulation of the ventral intermediate nucleus is an adequate operative intervention that can help to reduce tremor even in patients with complicated movement disorders.
