An evaluation of hardware and surgical complications with deep brain stimulation based on diagnosis and lead location.
Deep brain stimulation is the most frequently performed neurosurgical procedure for movement disorders. This procedure is well tolerated, but not free of complications. Analysis of hardware complications based on patient diagnosis and lead location could prove valuable in recognizing potential pitfalls and patients at higher risk. ⋯ This large series of patients and long-term follow-up demonstrate that risks of complications are not universal among movement disorder patients. Diagnosis and lead location are important risk stratification factors in determining complications.

Review Case ReportsLaser interstitial thermal therapy for focal cerebral radiation necrosis: a case report and literature review.
Whole-brain radiotherapy and stereotactic radiosurgery (SRS) play a central role in the treatment of metastatic brain tumors. Radiation necrosis occurs in 5% of patients and can be very difficult to treat. The available treatment options for radiation necrosis include prolonged high-dose corticosteroids, hyperbaric oxygen, anticoagulation, bevacizumab, and surgical resection. ⋯ Additionally, the patient was completely weaned off steroids. To our knowledge this is the first report using LITT for the treatment of focal radiation necrosis. LITT may be an effective treatment modality for patients with medically refractory radiation necrosis with lesions not amenable to surgical decompression.

ReviewDeep brain stimulation for Tourette syndrome: target selection.
Tourette syndrome (TS) is a complex neurological disorder manifested chiefly by motor and phonic tics and a variety of behavioral comorbidities, including attention disorder, obsessive-compulsive disorder and impulse control problems. Surgical treatment is increasingly considered when tics become troublesome or even disabling or self-injurious despite optimal medical therapy. In this review, we describe the surgical techniques, stimulation parameters, outcomes of deep brain stimulation (DBS) in TS, and critically review target choices. ⋯ Determination of the optimal surgical target will require a multicenter, randomized trial, and an expanded understanding of the neurobiology of TS.

Weight change after globus pallidus internus or subthalamic nucleus deep brain stimulation in Parkinson's disease and dystonia.
Weight gain has been described in Parkinson's disease (PD) patients after subthalamic nucleus (STN) deep brain stimulation (DBS). ⋯ Our results support previous reports of weight gain after DBS in PD. This is the first report to suggest a target-specific increase in weight following STN DBS in dystonia patients.

Comparative StudyChanging practice patterns of deep brain stimulation in Parkinson's disease and essential tremor in the USA.
Randomized controlled studies have shown deep brain stimulation (DBS) to be an effective treatment for Parkinson's disease (PD). Outside of large-center studies, little is known about trends in DBS use in the USA. ⋯ Patients who underwent DBS in the 2007 sample were older and had more comorbidities than those in the 2000 sample; in-hospital complications remained low. Understanding trends in DBS is helpful in assessing how the technology is adopted and what relationships should be further explored.
