Meta-analysis: Stroke Response Times Early in COVID-19 Depended on Metric, Type of Center

Delays in stroke treatment were inevitable during the early months of the COVID-19 epidemic, given virus-related precautions and the massive influx of COVID-19 patients into hospitals. Understanding the precise extent of those delays is important to learn what factors lead to late care.


Cognitive Deficits Present Across Domains in Schizophrenia and Relate to Positive Symptoms

Johanna Seitz-Holland, PhD, Marek Kubicki, MD, PhD, of the Department of Psychiatry at the Brigham, and colleagues recently became the first to investigate cognitive deficits in schizophrenia in a large-scale, thoroughly harmonized sample.


Penetrating the Blood-Brain Barrier to Improve Efficiency of Gene Therapy Delivery

The Brigham’s Fengfeng Bei, PhD, and team have reported on a new adeno-associated virus variant that delivers gene therapy across the blood-brain barrier in non-human primates more efficiently than previously developed vehicles. It could have implications for treating neurodegenerative diseases including Alzheimer’s.


Both Clinical Features, Assay Results Need Consideration in Diagnosis of MOG-AD

Demyelination of neuron, the damage of the neuron myelin sheath seen in demyelinating diseases

Giovanna S. Manzano, MD, of the Department of Neurology at Brigham and Women’s Hospital, Marcelo Matiello, MD, of Massachusetts General Hospital, and colleagues determined positive predictive values of a live cell–based serum assay that detects the diagnostic biomarker for MOG-AD in a real-world cohort.


New Cell Atlas Poised to Support Development of Migraine Therapies

Brigham investigators have mapped out a group of cells in the trigeminal ganglia that drive migraine pain, allowing them to further characterize the cells in a way that holds promise for developing new therapeutics. Neurologist and lead author William R. Renthal, MD, PhD, elaborates on the study.


CRP-to-Albumin Ratio Reflects Risk of Adverse Events After Spinal Epidural Abscess Treatment

Matthew H. Lindsey, MD, Andrew J. Schoenfeld, MD, MSc, of the Department of Orthopaedic Surgery at Brigham and Women’s Hospital, and colleagues have published putative evidence that the C-reactive protein to albumin ratio can help predict adverse events after spinal epidural abscess treatment.


Newly Identified Role of α-Synuclein May Lead to Novel Parkinson’s Disease Therapy

Vikram Khurana, MD, PhD, and colleagues have discovered an additional function of α-Synuclein—it modulates the stability of mRNA, thereby regulating gene expression. They explain the implications for understanding normal cellular physiology and developing therapies for Parkinson’s disease and related disorders.


Addressing the FINER Points of Chronic Pain Management

Brigham physiatrist Danielle L. Sarno, MD, is committed to reducing chronic pain among patient populations by increasing access to interdisciplinary pain care and linking patients to pain management resources. She and Jennifer Kurz, MD, established a program to help people find long-term solutions for chronic pain.


Brain-derived Neurotrophic Factor Linked to Improved Cognitive Performance in Older Adults

Kirk R. Daffner, MD, and colleagues found five weeks of cognitively stimulating activity by healthy older adults increased brain-derived neurotrophic factor (BDNF) levels and cognitive performance. They report evidence that the improvement in cognition with training was mediated by increases in BDNF.


Utility of a Neurosurgical “Boot Camp” for Medical Students

Garth Rees Cosgrove, MD, Michael A. Mooney, MD, of the Department of Neurosurgery at Brigham and Women’s Hospital, and colleagues recently organized a pilot in-person cadaveric workshop for medical students. It included hands-on teaching of craniotomy-related skills by neurosurgery faculty and residents.
