Comparative StudyBrain shift during deep brain stimulation surgery for Parkinson's disease.
Brain shift may occur during deep brain stimulation (DBS) surgery, which may affect the position of subcortical structures, compromising target localization. ⋯ Subcortical structures shift during DBS surgery. This shift appears to be gravity-dependent since structures only shifted posteriorly, and patients were primarily in the supine position. Posterior shift of RN may indicate STN displacement. Such positional change may compromise target localization, requiring multiple microelectrode adjustments. This may provide indirect justification for the necessity of microelectrode recordings during DBS surgery.

Comparative StudyStereotactic MRI in DYT1 dystonia: focal signal abnormalities in the basal ganglia do not contraindicate deep brain stimulation.
To study stereotactic magnetic resonance imaging (MRI) features of the basal ganglia in DYT1 primary dystonia. ⋯ T(1)-hypointense/T(2)-hyperintense signal abnormalities are common findings in the putamen and globus pallidus of DYT1 patients but do not contraindicate DBS. However, their presence within the GPi may reduce the efficacy of DBS treatment.

Case ReportsOccipital nerve stimulation for refractory occipital pain after occipitocervical fusion: expanding indications.
Occipital nerve stimulation is being used for various pain syndromes. Here, we expand its use for the treatment of refractory occipital pain after occipitocervical fusion. ⋯ Occipital nerve stimulation for medical refractory occipital neuralgia after occipitocervical fusion is an effective method expanding the indications for its use.

Comment LetterThe paradoxical role of dopamine after subthalamic nucleus deep brain stimulation--downstream is upstream in a circuit diagram. Comment on "Does dopamine still have a leading role in advanced Parkinson's disease after subthalamic stimulation?" (Stereotact Funct Neurosurg 2008;86: 184-186).
