BACKGROUND Deep brain stimulation (DBS) has been utilized to treat various symptoms in patients suffering from movement disorders such as Parkinson's disease, dystonia, and essential tremor. Though ataxia syndromes have not been formally or frequently addressed with DBS, there are patients with ataxia and associated medication refractory tremor or dystonia(More)
The use of neuromodulatory techniques in the treatment of neurological disorders is expanding and now includes devices targeting the motor cortex, basal ganglia, spinal cord, peripheral nervous system, and autonomic nervous system. In this chapter, we review and discuss the current and past literature as well as review indications for each of these devices(More)
Parkin mutations are a common cause of early-onset Parkinson's disease. To study the clinical features and treatment responses of patients with homozygous or heterozygous Parkin mutations, we performed a retrospective chart review in six early-onset parkinsonism patients with pathogenic Parkin mutations. The clinical phenotypes observed in this cohort, all(More)
Deep brain stimulation has been utilized to improve disease symptoms in patients with Parkinson's disease, dystonia, essential tremor, and other neuropsychiatric syndromes such as depression and obsessive compulsive disorder. Deep brain stimulation has also been observed to improve tremor for select patients with multiple sclerosis. During intraoperative(More)
Anterocollis is a type of cervical dystonia characterized by simultaneous and repetitive antagonist muscles contractions, resulting in abnormal neck flexion. It was described with a frequency of 6.8% from 399 patients with diagnosis of cervical dystonia and usually coexists with torticollis and/or laterocollis, as mixed cervical dystonia patterns.
