Cognitive loss after brain trauma results from sex-specific activation of synaptic pruning processes.

Cognitive losses resulting from severe brain trauma have long been associated with the focal region of tissue damage, leading to devastating functional impairment. For decades, researchers have focused on the sequelae of cellular alterations that exist within the perilesional tissues; however, few pharmacological therapies are available to patients. To examine whether expansive global synaptic damage underlies cognitive losses associated with brain injury, we evaluated the influence of D-serine on synaptic damage in male and female wild type mice as well mice deficient in microglial serine racemase (TMEM119creErt2:SRRfl/fl) or neuronal GluN2B (CamKIIcreErt2:Grin2bfl/fl).

The impact of mild-to-moderate cortical cognitive deficits on post-operative outcomes in deep brain stimulation for Parkinson's disease: Considerations for patient selection.

Introduction: Subcortical deficits in Parkinson's disease (PD) are well studied; however, deep brain stimulation (DBS) risks posed by mild-moderate deficits in semantic fluency, verbal memory storage, and confrontation naming are not as well understood. This study aims to better define DBS risk stratification criteria by evaluating whether pre-DBS cortical domain deficits predict surgical outcomes, including cognition, mood, quality of life, medication and motor function in patients with PD.

Methods: A retrospective study was conducted with 50 PD patients who underwent pre- and post-surgical neurological and neuropsychological evaluations between 2015 and 2023.

Sustained Therapeutic Benefits Using Image-Guided Programming at Activation of Deep Brain Stimulation for Parkinson's Disease.

Background: The efficacy of deep brain stimulation (DBS) for Parkinson's disease (PD) depends on optimizing stimulation parameters for each patient, a time-sensitive process. Image-guided programming (IGP) offers a promising method to streamline this.

Objective: The objective was to evaluate the real-world effectiveness of an IGP tool with directional leads during the initial programming of bilateral subthalamic nucleus (STN) or globus pallidus internus (GPi) DBS in PD patients.

5-year follow-up of a fully implanted brain-computer interface in a spinal cord injury patient.

Spinal cord injury (SCI) affects over 250 000 individuals in the US. Brain-computer interfaces (BCIs) may improve quality of life by controlling external devices. Invasive intracortical BCIs have shown promise in clinical trials but degrade in the chronic period and tether patients to acquisition hardware.

Cognitive dysfunction following brain trauma results from sex-specific reactivation of the developmental pruning processes.

Cognitive losses resulting from severe brain trauma have long been associated with the focal region of tissue damage, leading to devastating functional impairment. For decades, researchers have focused on the sequelae of cellular alterations that exist within the perilesional tissues; however, few clinical trials have been successful. Here, we employed a mouse brain injury model that resulted in expansive synaptic damage to regions outside the focal injury.

Deep Brain Stimulation for an Unusual Presentation of Myoclonus Dystonia Associated with Russell-Silver Syndrome.

Background: Myoclonus dystonia syndrome typically results from autosomal dominant mutations in the epsilon-sarcoglycan gene (SGCE) via the paternally expressed allele on chromosome 7q21. There is evidence that deep brain stimulation (DBS) is beneficial for this genotype, however, there are few prior case reports on DBS for myoclonus dystonia syndrome secondary to other confirmed genetic etiologies.

Case Report: A 20-year-old female with concomitant Russell-Silver syndrome and myoclonus dystonia syndrome secondary to maternal uniparental disomy of chromosome 7 (mUPD7) presented for medically refractory symptoms.

Navigated Dorsal Root Ganglion Stimulation (DRGS) for the Treatment of Chronic Refractory Coccygodynia: A Case Report.

Sacral stimulation is a well-established therapy for urologic neuromodulation. After the advent of dorsal root ganglion (DRG) stimulation, pain surgeons have started to reach this target mostly for pelvic and sacral pain. For those without good surgical experience, sacral foramen puncture, especially S3 and S4, can be a challenge, due to its entry angle and limited C-arm image resolution.

Middle Meningeal Artery Embolization for Chronic Subdural Hematoma Related to Autosomal Dominant Polycystic Kidney Disease.

Autosomal dominant polycystic kidney disease (ADPKD) is a connective tissue disease with vascular abnormalities involving multiple organs. The prevalence of ADPKD associated with a spontaneous subdural hematoma (SDH) is very low, with less than 10 cases reported in the literature to date. Symptomatic chronic SDH is classically treated with a twist drill, burr holes, or craniotomy.

Brain-Computer interface control of stepping from invasive electrocorticography upper-limb motor imagery in a patient with quadriplegia.

Most spinal cord injuries (SCI) result in lower extremities paralysis, thus diminishing ambulation. Using brain-computer interfaces (BCI), patients may regain leg control using neural signals that actuate assistive devices. Here, we present a case of a subject with cervical SCI with an implanted electrocorticography (ECoG) device and determined whether the system is capable of motor-imagery-initiated walking in an assistive ambulator.

The Cost of Gunshot Wounds to the Head: An Unevenly Distributed Burden.

Background: Despite the significant clinical consequences and socioeconomic costs of gunshot wounds to the head (GSWH), studies examining prehospital risk factors, geospatial patterns, and economic cost are lacking.

Methods: A retrospective analysis was performed for patients with GSWH (single or multiple injuries) presenting to the level one Ryder Trauma Center (hospital patients) as well as the Miami-Dade County Medical Examiner (ME) Department, from October 2013 to October 2015. In addition, ME data were queried from the previous decade (2008-2017) to analyze longitudinal trends.

Neurologic Outcomes for Octogenarians Undergoing Emergent Surgery for Traumatic Acute Subdural Hematoma.

Background: Determining the appropriate surgical indications for obtunded octogenarians with traumatic acute subdural hematoma (aSDH) has been challenging. We sought to determine which easily available data would be useful adjuncts to assist in early and quick decision-making.

Methods: We performed a single-center, retrospective review of patients aged ≥80 years with confirmed traumatic aSDH who had undergone emergent surgery.

Source-sink connectivity: a novel interictal EEG marker for seizure localization.

Over 15 million epilepsy patients worldwide have drug-resistant epilepsy. Successful surgery is a standard of care treatment but can only be achieved through complete resection or disconnection of the epileptogenic zone, the brain region(s) where seizures originate. Surgical success rates vary between 20% and 80%, because no clinically validated biological markers of the epileptogenic zone exist.
