Most COVID-19 long-haulers continue to experience neurologic symptoms, fatigue, and compromised quality of life 15 months after initial infection
A new study published in Annals of Clinical and Translational Neurology looked at the evolution of neurologic symptoms in non-hospitalized COVID-19 long-haulers at the Northwestern Medicine Neuro COVID-19 Clinic and discovered most long-haulers continue to experience symptoms such as brain fog, numbness/tingling, headache, dizziness, blurred vision, tinnitus and fatigue on average of 15 months after disease onset.

New study finds persistent viral shedding of COVID-19 is associated with delirium and six-month mortality in hospitalized COVID-19 patients
The Northwestern Medicine Neuro COVID-19 research team discovered patients who continued to test positive more than 14 days after their initial positive test were more likely to experience delirium, longer hospital stays, were less likely to be discharged home, and had a greater six-month mortality than those without persistent viral shedding of COVID-19.

Key to resilient energy-efficient AI/machine learning may reside in human brain
A clearer understanding of how a type of brain cell known as astrocytes function and can be emulated in the physics of hardware devices, may result in artificial intelligence (AI) and machine learning that autonomously self-repairs and consumes much less energy than the technologies currently do, according to a team of Penn State researchers.

Identification of SSRI-evoked antidepressant sensory signals by decoding vagus nerve activity
Abstract The vagus nerve relays mood-altering signals originating in the gut lumen to the brain. In mice, an intact vagus is required to mediate the behavioural effects of both intraluminally applied selective serotonin reuptake inhibitors and a strain of Lactobacillus with antidepressant-like…
Researchers map neurons in the brain involved with social interactions with others in groups
Meaningful social interactions are critical to an individual’s well-being, and such interactions rely on people’s behaviors towards one another.
Physical exercise modulates iron in Alzheimer’s disease
A recent experimental study shows how regular physical exercise modulates iron metabolism in both the brain and the muscles.
Flawed quality control in the brain
Proteins are the “tools” of our cells – they are essential to all vital tasks.
Readiness to punish others for selfish behaviour explained by functional brain connections
The stronger the functional brain connections, the less inclined someone is to punish others for unfair behaviour.
People With Stroke Who Walk 30 Minutes Per Day May Have 54% Lower Risk of Death
MINNEAPOLIS – A new study shows that people who walk or garden at least three to four hours per week, or bike at least two to three hours per week, or the equivalent after having a stroke may have a 54% lower risk of death from any cause. The research is published in the August 11, 2021, online issue of Neurology®, the medical journal of the American Academy of Neurology. The study found the most benefit for younger stroke survivors. When people under the age of 75 exercised at least that amount, their risk of death was reduced by 80%.
Brain Connectivity Can Build Better AI
A new study shows that artificial intelligence networks based on human brain connectivity can perform cognitive tasks efficiently.

Marijuana-Like Brain Substance Calms Seizures but Increases Aftereffects, Study Finds
Epileptic seizures trigger the rapid synthesis and release of a substance mimicked by marijuana’s most psychoactive component, Stanford University School of Medicine investigators have learned.
Molecular Atlas Reveals How Brain Cells Develop
As the fertilized egg divides, initially undifferentiated cells take on specific functions, becoming more distinct as different tissues and organs emerge.
Scientists Reverse Age-Related Memory Loss in Mice
Scientists at Cambridge and Leeds have successfully reversed age-related memory loss in mice and say their discovery could lead to the development of treatments to prevent memory loss in people as they age.
Henry Ford Health System First in the U.S. to Offer Next Generation Deep Brain Stimulation System For Parkinson’s Disease
The Parkinson’s Disease and Movement Disorder Center at Henry Ford Health System was the first in the United States to offer a new FDA-approved device to help treat the symptoms of Parkinson’s disease. Neurosurgeon Jason Schwalb, M.D. surgically implanted the Vercise Genus™ Deep Brain Stimulation (DBS) System, which stimulates a targeted region of the brain through implanted leads that are placed in the brain.
University of Minnesota, Van Andel Institute earn $6M to study aging’s role in Parkinson’s
GRAND RAPIDS, Mich. (Sept. 21, 2020) — A collaborative team between the University of Minnesota Medical School and Van Andel Institute (VAI) will soon begin a $6.2 million study that seeks to define the molecular linkages between aging and Parkinson’s disease — an approach for new treatment targets not yet explored by many researchers. The group recently earned a three-year grant from the Aligning Science Across Parkinson’s initiative, an international collaborative research effort partnering with The Michael J. Fox Foundation for Parkinson’s Research to implement its funding.
