Abstract
BACKGROUND AND IMPORTANCE:
Peripheral and central sensory loss are often associated with significant tremor or sensory ataxia, which can be highly refractory to medical therapy.
CLINICAL PRESENTATION:
We present the case of a 67-year-old man with progressive and debilitating intention tremor from monoclonal gammopathy-associated peripheral neuropathy. The patient was implanted with bilateral thalamic deep brain stimulator electrodes under microelectrode guidance. Following optimization of stimulation parameters, the patient's appendicular tremor and gait improved, as did his general activities of daily living.
CONCLUSION:
These initial findings suggest that deep brain stimulation may benefit not only tremor presumed to originate from central nervous system dysfunction, but also tremor originating peripherally from neuropathy-related sensory loss.
