The etiological agent of coronavirus disease-19 (COVID-19), SARS-coronavirus-2 (SARS-CoV-2), emerged in Wuhan, China, and quickly spread worldwide leading the World Health Organization (WHO) to recognize it not only as a pandemic but also as an important thread to public health. Beyond respiratory symptoms, new neurological manifestations are being identified such as headache, ageusia, anosmia, encephalitis or acute cerebrovascular disease. ⋯ Anti-herpes simplex virus (HSV) 1 and varicella-zoster IgM antibodies were not detected in serum samples and spinal and brain magnetic resonance imaging (MRI) showed no abnormal findings. This case remarks that COVID-19 nervous system damage could be caused by immune-mediated mechanisms.

Research productivity is a vital component to an academic neurosurgeon's career. We sought to evaluate gender differences in NIH funding among faculty in neurological surgery departments. NIH funding awarded to PIs of neurological surgery departments from 2014 to 2019 were obtained and analyzed for gender differences in funding trends, with attention to terminal degree and academic rank, as well as publication range in length of years and h-index. 79.4% of all NIH grants were awarded to male PIs, with the remaining 20.5% given to their female counterparts. ⋯ Differences in mean NIH funding per grant approached but did not reach statistical significance between men and women (P = 0.122). When stratified for academic rank, there was a significant difference in mean NIH funding per grant between men and women on the associate professor level (p < 0.005), with women exceeding men in funding at this academic level, with other academic ranks remaining non-significant. Overall, male neurosurgeons receive significantly more total NIH grant funding than their female counterparts, except at the level of associate professor where women were found to surpass men.

Comparative Study
Aneurysmal subarachnoid hemorrhage in patients with migraine and tension headache: A cohort comparison study.
Migraine headache is a common condition with an estimated lifetime prevalence of greater than 20%. While it is a well-established risk factor for cardiovascular disease and ischemic stroke, its association with subarachnoid hemorrhage is largely unexplored. We sought to compare the incidence of aneurysmal subarachnoid hemorrhage in a cohort of migraine patients with a cohort of patients with tension headache. ⋯ CPH regression on matched data showed that treated migraine patients had a significantly lower hazard of aneurysmal subarachnoid hemorrhage compared with tension headache patients (HR = 0.40, 95% CI: 0.19 - 0.86, p = 0.02). This large cohort comparison study, analyzing more than 679,000 patients, demonstrated that migraine patients undergoing pharmacologic treatment had a lower hazard of aneurysmal subarachnoid hemorrhage than patients diagnosed with tension headaches. Future work specifically focusing on migraine medications may identify the mechanisms underlying this association.

Neurological complications of coronavirus 2019 (COVID-19) are common, and novel manifestations are increasingly being recognized. Mild encephalopathy with reversible splenium lesion (MERS) is a syndrome that has been associated with viral infections, but not previously with COVID-19. ⋯ His symptoms resolved and the brain MRI findings completely normalized on repeat imaging, consistent with MERS. This case suggests that MERS may manifest as an autoimmune response to SARS-CoV-2 infection and should be considered in a patient with evidence of recent COVID-19 infection and the characteristic MERS clinico-radiological syndrome.
