An Algorithm for Management of Deep Brain Stimulation Battery Replacements: Devising a Web-Based Battery Estimator and Clinical Symptom Approach

Short pauses in thalamic deep brain stimulation promote tremor and neuronal bursting

“…Some subjects experienced discomfort in response to intraoperative stimulation at the clinically programmed stimulation amplitude, and the voltage was decreased to the maximum tolerable level for these individuals (3/9 subjects). IPGs near end-of-life often require an increased stimulation amplitude to compensate for lower current output due to decreased battery supply voltage [Montuno et al, 2013]. Therefore, intraoperative stimulation at the clinically programmed voltage may have caused discomfort due to delivery of more current than the depleted IPG produced.…”

Deep brain stimulation (DBS) at the interface of neurology and psychiatry

“…Recent advances in target selection may reduce this latency to days in the case of depression (28). There is a risk of device malfunction (29), and in all cases, neurostimulator replacement may be necessary (30), provided the DBS patient outlives the device (i.e., typically two to five years for device replacement and seven to ten years for rechargeable batteries).…”

Letter: Evaluation and Surgical Treatment of Functional Neurosurgery Patients With Implanted Deep Brain Stimulation and Vagus Nerve Stimulation Pulse Generators During the COVID-19 Pandemic

“…[10][11][12][13][14] • At this time, there is no evidence that other groups of patients are at risk for life-threatening symptoms from DBS cessation, but this could change with the course of time. • Though not life-threatening per se, severe symptoms upon DBS cessation due to battery depletion 15 should be evaluated for urgent surgery on a case-by-case basis, and in an effort to minimize hospitalizations or evaluations in the emergency department.…”
