Large-scale studies link preoperative cognition to delirium risk, reveal its deadly toll after surgery
Editor's Note Older surgical patients with preoperative cognitive impairment face significantly higher odds of developing postoperative delirium (POD), and POD itself is tied to markedly worse surgical outcomes, according to two major studies published July 2025. Together, the findings point to delirium as both a high-impact and potentially modifiable target…
Study: Mixed reality system shows promise as alternative to optical neurosurgical navigation
Editor's Note A mixed reality navigation (MRN) system for neurosurgery achieved performance comparable to traditional optical navigation (TON) in certain clinical scenarios, while significantly reducing equipment costs, according to an August 1 study published in BMC Surgery. The MRN system, built around a Microsoft HoloLens headset and infrared tracking tools,…
FDA designates Class 1 recall for cranial drill
Editor's Note The US Food and Drug Administration (FDA) has designated Integra LifeSciences’ recall of specific Codman Disposable Perforators and Craniotomy Kits a Class 1, the most severe category indicating serious risk of injury or death.

Study: Long working hours alter brain regions tied to emotion, cognition
Editor's Note Clocking long hours has impact beyond fatigue. It may also physically reshape the brain. As reported May 13 by CNN, that is the central finding of a new study showing significant structural brain changes in overworked individuals, particularly in areas tied to emotional regulation and executive function. Conducted…
Study: EEG-guided anesthesia halves anesthetic use, accelerates recovery in pediatric surgery
Editor's Note EEG-guided anesthesia reduces drug use and speeds recovery in children, according to an April 22 report in Neuroscience News. The article focuses on a clinical trial, conducted in Japan and published April 21 in JAMA Pediatrics, comparing standard anesthesia dosing with EEG-guided dosing in more than 170 surgical…
Experimental brain implant translates thoughts to speech
Editor's Note A new brain implant could one day restore voices to those who can no longer speak, the Associated Press (AP) reported March 31. As detailed in the article, researchers have successfully tested the experimental brain-computer interface (BCI) on a 47-year-old woman with quadriplegia who lost the ability to…
Real-time cancer detection improves brain surgery precision
Editor's Note A new genetic testing tool could allow surgeons to accurately identify cancer cells in real time during brain surgery, potentially improving surgical outcomes and reducing cancer recurrence, NYU Langone Health System announced. According to a February 25 press release, the Ultra-Rapid droplet digital PCR (UR-ddPCR) technique identifies cancer…
Study: Preoperative stereotactic radiosurgery shows promise in brain metastases management
Editor's Note A new international study reports low rates of local recurrence, radionecrosis, and leptomeningeal disease in patients receiving neoadjuvant stereotactic radiosurgery (SRS) before brain metastases resection, Medscape Medical News reported January 6. Published in Radiotherapy and Oncology, the analysis included 179 patients with 189 brain metastases treated at nine…
Study links multiple surgeries, cognitive decline in older adults
Editor's Note Multiple surgeries can spur gradual cognitive decline in older adults, according to recent research from the University of Sydney. Published in The Lancet Healthy Longevity and detailed in a September 27 university announcement, the study followed nearly half a million adults aged 40 to 69 over 20 years…
Real-time mass spectrometry identifies brain cancer mutations during surgery
Editor's Note A mass spectrometry platform that identifies key brain cancer mutations in real-time during surgery shows potential for improving outcomes in a procedure when time is of utmost importance, Technology Networks reported June 3. Developed by the Mayo Clinic, the platform specifically targets dehydrogenase (IDH) mutations on samples taken…
