Anne Cross, MD, FAAN, professor of neurology at Washington University, who was not involved with the studies, said that, coupled with similar findings from a research group in Germany and an earlier analysis from Dr. Bove’s group, the data on ocrelizumab are “very reassuring.”

Subtle cognitive decline precedes end to driving for older adults (Links to an external site)
One of the thorniest decisions facing older adults is when to give up their keys and stop driving. A new study by researchers at Washington University School of Medicine in St. Louis could provide guidance in helping seniors plan ahead. The researchers found that impaired cognitive function foreshadows the decision for many seniors to stop […]
Sleep Apnea Reduced in People Who Took Weight-Loss Drug, Eli Lilly Reports (Links to an external site)
The pharmaceutical manufacturer Eli Lilly announced on Wednesday that its obesity drug tirzepatide, or Zepbound, provided considerable relief to overweight or obese people who had obstructive sleep apnea, or episodes of stopped breathing during sleep.
Alzheimer’s disease progresses faster in people with Down syndrome (Links to an external site)
Nearly all adults with Down syndrome will develop evidence of Alzheimer’s disease by late middle age. A new study by researchers at Washington University School of Medicine in St. Louis shows that the disease both starts earlier and moves faster in people with Down syndrome, a finding that may have important implications for the treatment […]
Epilepsy drug prevents brain tumors in mice with NF1 (Links to an external site)
A drug used to treat children with epilepsy prevents brain tumor formation and growth in two mouse models of neurofibromatosis type 1 (NF1), according to a study by researchers at Washington University School of Medicine in St. Louis. NF1 is a genetic condition that causes tumors to grow on nerves throughout the body, including the […]
High BMI lowers odds for nerve stimulation treatment response in OSA (Links to an external site)
Hypoglossal nerve stimulation reduced obstructive sleep apnea severity; however, this outcome was less likely among those with higher BMIs and those who slept in supine position, according to study results. “Physicians can take both this new information about BMI and sleeping on your back vs. your side into consideration when counseling patients with OSA,” Eric C. Landsness, […]
CPAP replacement works well for the overweight, not obese, study finds (Links to an external site)
An implant for obstructive sleep apnea — a serious sleep malady in which breathing stops for 10 seconds to two minutes many times an hour each night — works best in people who are overweight but not severely obese, a new study found. To qualify for the device, called a hypoglossal nerve stimulator, a person over 18 diagnosed with […]
Nerve stimulation for sleep apnea is less effective for people with higher BMIs (Links to an external site)
A nerve-stimulation treatment for obstructive sleep apnea that originally was approved only for people with body mass indexes (BMIs) in the healthy range recently was extended to patients with BMIs up to 40, a weight range generally described as severely obese. A healthy BMI ranges from 18.5 to 24.9.
Immunotherapy for Alzheimer’s disease shows promise in mouse study (Links to an external site)
Alzheimer’s disease starts with a sticky protein called amyloid beta that builds up into plaques in the brain, setting off a chain of events that results in brain atrophy and cognitive decline. The new generation of Alzheimer’s drugs — the first proven to change the course of the disease — work by tagging amyloid for […]
Two Studies, Two Different Conclusions on Biomarkers for Lewy Body Dementia (Links to an external site)
Two studies of commercially available biomarkers of synucleinopathies have reached sharply different conclusions on their reliability, according to the findings from two abstracts presented at the AAN Annual Meeting, held in Denver in April.
