The phenotype of patients who suffer fatal traumatic brain injury (TBI) is poorly characterized. The authors examined the external causes, contributing diseases, and preinjury medication in adult patients with fatal TBI in a nationwide Finnish cohort. ⋯ TBI is a common cause of death in young adults, whereas the incidence of fatal TBI becomes increasingly higher with age in Finland. Cardiovascular diseases and psychiatric conditions were the most common diseases related to death, with opposite age trends. Healthcare facility complications were an alarmingly common cause of death in women with fatal TBI.

Clinical and genomic differences in supratentorial versus infratentorial NF2 mutant meningiomas.
Mutations in NF2 are the most common somatic driver mutation in sporadic meningiomas. NF2 mutant meningiomas preferentially arise along the cerebral convexities-however, they can also be found in the posterior fossa. The authors investigated whether NF2 mutant meningiomas differ in clinical and genomic features based on their location relative to the tentorium. ⋯ Supratentorial NF2 mutant meningiomas are associated with more aggressive clinical and genomic features as compared with their infratentorial counterparts. Although infratentorial tumors have higher rates of subtotal resection, there is no associated difference in survival or recurrence. These findings help to better inform surgical decision-making in the management of NF2 mutant meningiomas based on location, and may guide postoperative management of these tumors.

Outcome of stereo-electroencephalography with single-unit recording in drug-refractory epilepsy.
The aim of this study was to evaluate the utility and safety of "hybrid" stereo-electroencephalography (SEEG) in guiding epilepsy surgery and in providing information at single-neuron levels (i.e., single-unit recording) to further the understanding of the mechanisms of epilepsy and the neurocognitive processes unique to humans. ⋯ Hybrid SEEG enables safe and effective localization of epileptogenic zones to guide epilepsy surgery and provides unique scientific opportunities to investigate neurons from various brain regions in conscious patients. This technique will be increasingly utilized due to the advent of RNS and may prove a useful approach to probe neuronal networks in other brain disorders.

An assessment of the long-term impacts of the coronavirus disease 2019 pandemic on academic neurosurgery.
The goal of this study was to survey residents, fellows, and residency program leadership to assess the long-term impacts of the coronavirus disease 2019 (COVID-19) on residency training by using a structured survey methodology. ⋯ This study provides a cross-section of the pandemic's impact on academic neurosurgery, highlighting the importance of continued efforts to assess and address the long-term consequences of the COVID-19 pandemic for US academic neurosurgery.

A taxonomy for deep cerebral cavernous malformations: subtypes of thalamic lesions.
Anatomical taxonomy is a practical tool to successfully guide clinical decision-making for patients with brain arteriovenous malformations and brainstem cavernous malformations (CMs). Deep cerebral CMs are complex, difficult to access, and highly variable in size, shape, and position. The authors propose a novel taxonomic system for deep CMs in the thalamus based on clinical presentation (syndromes) and anatomical location (identified on MRI). ⋯ This study confirms the authors' hypothesis that this taxonomy for thalamic CMs can meaningfully guide the selection of surgical approach and resection strategy. The proposed taxonomy can increase diagnostic acumen at the patient bedside, help identify optimal surgical approaches, enhance the clarity of clinical communications and publications, and improve patient outcomes.
