Voluntary finger-nose movements of the arm were analysed in six patients undergoing stereotaxic nucleus ventralis intermedius thalamotomy for relief of severe Parkinsonian tremor. In all cases thalamotomy acutely abolished tremor in the contralateral arm. In the early postoperative phase, ataxia of the arm contralateral to the operated side was also seen. Ataxia was transient, lasting between 7 and 21 days postoperatively. This observation suggests that a lesion of the Vim nucleus interrupts cerebellar input to the thalamus, and supports the concept that abnormal cerebellar activity is an important contributor to the generation of tremor in Parkinson's disease.

We report a fatal intoxication in a 59-year-old woman who had uremia undergoing hemodialysis, and then took amantadine and pramipexole for Parkinsonian tremor. Toxic manifestation includes myoclonus, ataxia, confusion and sudden death. This report highlights the fact that using amantadine and pramipexole may be fatal in patients with uremia even undergoing hemodialysis.

Tremor is the most common involuntary movement disorder. It can be an isolated symptom or a symptom of another neurological disorder, such as dystonia, Parkinson disease, spinocerebellar ataxia et al. It is an unintentional, somewhat rhythmic, muscle movement involving to-and-fro movements of one or more parts of the body. It can affect the hands, arms, head, vocal cord, jaw, chin, and legs. Most tremors occur in the hands. Clinically, the most useful way to categorized tremor is whether it occurs mainly at rest, on postural, or during movement (kinetic tremor). Tremor is most common classified by different clinical features and cause or origin; include essential tremor, Parkinsonian tremor, cerebellar tremor, dystonic tremor, orthostatic tremor, physiologic tremor, and psychogenic tremor. Diagnosis need a detail history (include familial inheritance, drugs exposure, alcohol consumption or withdraw); complete physical examination and laboratory tests. Electromyography is also a simple and quick method with which to calculate tremor frequency and amplitude for assisting diagnosis. Treatment for majority of tremor syndrome is purely symptomatic, and is similar regardless of the underlying cause of the tremor. There are different medicines to try in order propranolol, clonazepam, primidome and gabapentin for limb tremors, or trihexyphenidyl for dystonic tremor. Focal botulinum toxin injection may be help in focal tremor. Neurosurgery is only indicated in severe tremor, such as deep brain stimulation (DBS) of subthalamic nucleus for primary or secondary parkinsonian tremor.
