Patients in a new Northwestern Medicine study were able to comprehend words that were written but not said aloud. They could write the names of things they saw but not verbalize them. Even though these patients could hear and speak perfectly fine, a disease had crept into a portion of their brain that kept them from processing auditory words while still allowing them to process visual ones. Patients in the study had primary progressive aphasia (PPA), a rare type of dementia that destroys language and currently has no treatment. The…

ACC/AHA guidance for preventing heart disease, stroke released
The choices we make every day can have a lasting effect on our heart and vascular health. Adopting a heart healthy eating plan, getting more exercise, avoiding tobacco and managing known risk factors are among the key recommendations in the 2019 Primary Prevention of Cardiovascular Disease guideline from the American College of Cardiology (ACC) and the American Heart Association (AHA). Also, it is recommended that aspirin should only rarely be used to help prevent heart attacks and stroke in people without known cardiovascular disease. The guideline, presented today at ACC’s…
Read MoreNew potential approach to treat atopic dermatitis
How does the immune system respond to fungi on our skin? Researchers at the University of Zurich have demonstrated that the same immune cells that protect us against skin fungi also encourage the inflammatory symptoms of atopic dermatitis. An antibody therapy could alleviate this chronic inflammatory skin disease. The skin of humans and animals is densely populated by fungi. It is suspected that a small yeast species called Malassezia, which besides bacteria and viruses is part of the microflora of healthy skin, strengthens the body’s defenses and prepares the immune…
Read MoreSmoking, high blood pressure, diabetes and obesity each linked to unhealthy brains
Factors that influence the health of our blood vessels, such as smoking, high blood and pulse pressures, obesity and diabetes, are linked to less healthy brains, according to research published in the European Heart Journal today (Monday). The study examined the associations between seven vascular risk factors and differences in the structures of parts of the brain. The strongest links were with areas of the brain known to be responsible for our more complex thinking skills, and which deteriorate during the development of Alzheimer’s disease and dementia. The researchers, led by Dr…
Read MoreFootwear habits influence child and adolescent motor skill development
New research finds that children and adolescents who spend most of their time barefoot develop motor skills differently from those who habitually wear shoes. Published in Frontiers in Pediatrics, this is the first study to assess the relevance of growing up shod vs. barefoot on jumping, balancing and sprinting motor performance during different stages of childhood and adolescence. The study shows that habitually barefoot children are noticeably better at jumping and balancing compared to habitually shod children, particularly from 6-10 years of age. While these beneficial barefoot effects diminished in older…
