Simple vision tests can predict which people with Parkinson s disease will develop cognitive impairment and possible dementia 18 months later, according to a new study by UCL researchers.
The study, published in
Movement Disorders, adds to evidence that vision changes precede the cognitive decline that occurs in many, but not all, people with Parkinson s.
In another new study published today in
Communications Biology, the same research team found that structural and functional connections of brain regions become decoupled throughout the entire brain in people with Parkinson s disease, particularly among people with vision problems.
The two studies together show how losses and changes to the brain s wiring underlie the cognitive impairment experienced by many people with Parkinson s disease.
Georgia State University biology researchers have found that infecting the nasal passages of mice with the virus that causes COVID-19 led to a rapid, escalating attack on the brain that triggered severe illness, even after the lungs were successfully clearing themselves of the virus.
Researchers from the National Institutes of Health have discovered Jekyll and Hyde immune cells in the brain that ultimately help with brain repair but.

Malta, a sovereign microstate in the middle of the Mediterranean Sea, has no shortage of sunny beaches, honey-bricked villages and rugged countryside. Beyond its Mediterranean charm, Malta is home to a geographically and culturally isolated population whose unique genetic makeup, makes this island nation a goldmine for genetics research.
Four years ago, the University of Malta set up a national ALS Registry and Biobank to identify patients with amyotrophic lateral sclerosis (ALS) and collect data on their residence, occupation, lifestyle and environmental exposures. Blood samples donated by participants will remain stored in high-tech storage facilities at the University over many years.
