Neurological Effects of Monkeypox Largely Unknown, Review Finds
Much remains unknown about the long-term neurologic effects of monkeypox. In anarticle published today inJAMA Neurology, researchers from the National Institute of Neurological Disorders and Stroke (NINDS) and colleagues described how reports of complications from other orthopoxviruses, such as smallpox, may offer clues about the neurologic consequences of monkeypox.“Although the COVID-19 pandemic is the worst pandemic in a century, the recent past has seen several major pandemics, including Zika, Ebola, dengue, West Nile, and AIDS,” wrote B. Jeanne Billioux, M.D., of NINDS and colleagues. “A common thread to these p...

New spectrum of the neurologic consequences of Zika
Zika virus infection represents a new neuropathological agent with association to a wide spectrum of neurological complications: a) Congenital Zika Syndrome by affecting the neural stem cells of the human fetal brain; b) Guillain-Barr é Syndrome by an autoimmune response against peripheral myelin and/or axonal components or probable direct inflammatory reaction; c) Encephalitis/meningoencephalitis and myelitis by a direct viral inflammatory process on the central nervous system; d) Sensory neuropathy by infecting directly the pe ripheral neurons and causing substantial cell death and pathogenic transcriptional dysregulati...

What Causes Microcephaly?
Discussion Microcephaly is usually defined as an occipitofrontal head circumference (OFC) more than 2 standard deviations (SD) below the mean for sex, age and ethnicity. Severe microcephaly is used for OFC < 3 standard deviations. Rates of microcephaly range from 0.5-12 patients/10,000 live births. The OFC should be measured at every well child visit and at other opportunities and plotted on standard growth charts. The OFC is measured using a nonelastic tape measure around the largest part of the head with the tape measure held above the eyebrows and ears. It is a highly reproducible measurement. There are several diff...
