A method for precisely timed, on-demand intracranial stimulation using the RNS device
While deep brain stimulation has become a cornerstone treatment for movement disorders, randomized controlled trials for diseases with complex cognitive and behavioral deficits, including Alzheimer's Disease and depression, have not demonstrated efficacy [1,2]. In these trials, stimulation was provided in a continuous, open-loop fashion. However, brain activity for higher-order cognitive processes, including learning and decision-making, has been extensively demonstrated to occur during short, precisely regulated epochs [3,4].

Comprehensive characterization of intracranial hemorrhage in deep brain stimulation: a systematic review of literature from 1987 to 2023
CONCLUSIONS: This study provides level III evidence that MER during DBS is a risk factor for ICH. Other risk factors include intraoperative systolic blood pressure > 140 mm Hg, sulcal trajectories, and multiple microelectrode insertions. Avoidance of these risk factors may decrease the rate of ICH.PMID:38518284 | DOI:10.3171/2024.1.JNS232385 (Source: Journal of Neurosurgery)

Updates on brain regions and neuronal circuits of movement disorders in Parkinson's disease

Epub 2023 Oct 28.ABSTRACTParkinson's disease (PD) is a progressive neurodegenerative disease with a global burden that affects more often in the elderly. The basal ganglia (BG) is believed to account for movement disorders in PD. More recently, new findings in the original regions in BG involved in motor control, as well as the new circuits or new nucleuses previously not specifically considered were explored.

Protocol for a scoping review of factors associated with disparities in clinical provision of deep brain stimulation
Introduction Deep brain stimulation (DBS) can be used to treat several neurological and psychiatric conditions such as Parkinson’s disease, epilepsy and obsessive-compulsive disorder; however, limited work has been done to assess the disparities in DBS access and implementation. The goal of this scoping review is to identify sources of disparity in the clinical provision of DBS. Methods and analysis A scoping review will be conducted based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses-extension for Scoping Reviews methodology. Relevant studies will be identified from databases including M...

The role of genetics in the treatment of dystonia with deep brain stimulation: Systematic review and Meta-analysis
Dystonia is a movement disorder characterized by sustained or intermittent muscle contractions that lead to involuntary postures or repetitive movements. Genetic mutations are being increasingly recognized as a cause of dystonia. Deep brain stimulation (DBS) is one of the limited treatment options available. However, there are varying reports on its efficacy in genetic dystonias. This systematic review of the characteristics of genetic dystonias treated with DBS and their outcomes aims to aid in the evaluation of eligibility for such treatment.

Effects of Deep-Brain Stimulation on Speech: Perceptual and Acoustic Data
CONCLUSIONS: Our data, in general, indicate no-to-minimal changes in speech production ensued from DBS stimulation. The findings are discussed with a focus on large interspeaker variability in PD in terms of their speech characteristics and the potential effects of DBS on speech.PMID:38498664 | DOI:10.1044/2024_JSLHR-23-00511 (Source: Journal of speech, language, and hearing research : JSLHR)

Enhancing Attentional Performance in Parkinson's Disease: The Impact of Combined Deep Brain Stimulation of the Substantia Nigra Pars Reticulata and the Subthalamic Nucleus
: The concomitant stimulation of the subthalamic nucleus and the substantia nigra pars reticulata is a promising approach to improve treatment of refractory axial symptoms in Parkinson`s disease. While dual stimulation of the subthalamic nucleus and the substantia nigra pars reticulata has previously shown beneficial effects on gait, the role of the substantia nigra, a crucial component of the basal ganglia circuitry, in cognitive functions such as attention an executive control remains underexplored.

Topographical anatomy of the subthalamic region with special interest in the human medial forebrain bundle
CONCLUSIONS: According to this study's findings, the streamlines of the MFB described by tractography arise from the limitations of the diffusion-weighted MRI fiber tracking method and actually correspond to subthalamic fiber bundles, especially the ansa lenticularis and lenticular fasciculus, which erroneously continue in the anterior limb of the internal capsule, toward the prefrontal cortex.PMID:38489821 | DOI:10.3171/2024.1.JNS232066 (Source: Journal of Neurosurgery)
