"Staying Home"-Early Changes in Patterns of Neurotrauma in New York City During the COVID-19 Pandemic.

Objective: New York City is the epicenter of the novel coronavirus disease 2019 (COVID-19) pandemic in the United States. Traumatic brain injury accounts for a significant proportion of admissions to our trauma center. We sought to characterize the effect of the pandemic on neurotraumas, given the cancellation of nonessential activities during the crisis.

Approach Angle Affects Accuracy in Robotic Stereoelectroencephalography Lead Placement.

Background: One third of patients with epilepsy fail to gain optimal control using antiepileptic drugs. New advances in epilepsy surgery have reshaped some diagnostic and therapeutic modalities into less invasive approaches. To understand the cortical epileptogenic networks, stereoelectroencephalography uses depth electrodes as a tool for invasive intracranial monitoring.

Quantitative Signal Characteristics of Electrocorticography and Stereoelectroencephalography: The Effect of Contact Depth.

Purpose: Patients undergoing epilepsy surgery often require invasive EEG, but few studies have examined the signal characteristics of contacts on the surface of the brain (electrocorticography, ECOG) versus depth contacts, used in stereoelectroencephalography (SEEG). As SEEG and ECOG have significant differences in complication rates, it is important to determine whether both modalities produce similar signals for analysis, to ultimately guide management of medically intractable epilepsy.

Methods: Twenty-seven patients who underwent SEEG (19), ECOG (6), or both (2) were analyzed for quantitative measures of activity including spectral power and phase-amplitude coupling during approximately 1 hour of wakefulness.

Robotic surgical rehearsal on patient-specific 3D-printed skull models for stereoelectroencephalography (SEEG).

Purpose: Medically refractory epilepsy patients commonly require surgical alternatives for diagnosis and treatment. Stereoelectroencephalography (SEEG) is a useful diagnostic procedure in seizure focus elucidation. Modern techniques involve the use of robotics and neuronavigation for SEEG.

Performance of language tasks in patients with ruptured aneurysm of the left hemisphere worses in the post-surgical evaluation.

Objective: To assess the language and verbal fluency performance in aneurismal SAH pre- and post-surgery in patients caused by an aneurysm of the anterior communicating artery (AcomA), left middle cerebral artery (L-MCA) and left posterior comunicating artery (L-PcomA).

Methods: Assessment in 79 patients with SAH, on two occasions: pre- and post surgical treatment. They were divided into three groups by the aneurysms' location.

Cognitive changes in patients with aneurysmal subarachnoid hemorrhage before and early posttreatment: differences between surgical and endovascular.

Introduction: The main purpose of occluding a ruptured aneurysm is preventing rebleeding, which may be fatal. Microsurgical or endovascular treatments are the main approaches adopted to prevent new bleeding. Among patients presenting with aneurysmal subarachnoid hemorrhage, about 50% had permanent injuries.

Language, memory, and verbal fluency changes in patients with aneurysmal subarachnoid hemorrhage: results of a preoperative investigation.

Objective: To detect changes in speech, verbal fluency, and memory in patients with subarachnoid hemorrhage (SAH) caused by ruptured aneurysms and to analyze the results before surgical or embolization procedure.

Methods: During the period May 2007 to November 2009, 193 patients with anterior aneurysmal SAH admitted to the Department of Neurosurgery, Hospital da Restauração, Recife, Brazil, were tested for speech, verbal fluency, and memory disturbances after the first week of bleeding and compared with a control group with similar demographics.

Results: Patients with aneurysmal SAH differed significantly from the control group in language, verbal fluency, and memory functions before clipping or coiling procedures.
