Hearing and visual impairments linked to elevated dementia risk

Older adults with both hearing and visual impairments—or dual sensory impairment—had a significantly higher risk for dementia in a recent study published in Alzheimer’s & Dementia: Diagnosis, Assessment & Disease Monitoring. In the study of 2,051 older adults (22.8% with hearing or visual impairment and 5.1% with both impairments) who were followed over eight years,Continue reading “Hearing and visual impairments linked to elevated dementia risk”

Boosting a liver protein may mimic the brain benefits of exercise

By Laura Sanders Exercise’s power to boost the brain might require a little help from the liver. A chemical signal from the liver, triggered by exercise, helps elderly mice keep their brains sharp, suggests a study published in the July 10 Science. Understanding this liver-to-brain signal may help scientists develop a drug that benefits theContinue reading “Boosting a liver protein may mimic the brain benefits of exercise”
