The study highlights the need for early diagnosis and support services for people with Down syndrome as they age.
A recent NIH-funded study highlights the need for research on aging individuals with Down syndrome. The analysis reveals that nearly a third of those aged 55+ have filed at least three claims for Alzheimer's disease.
A high-salt diet can cause cognitive impairment by activating a pathway in the brain that leads to tau protein clumping, according to a new study. The researchers found that this effect is not due to a loss in blood flow to the brain, but rather to the accumulation of tau protein aggregates that interfere with brain cell function.
A high-salt diet may negatively affect cognitive function by causing a deficiency of nitric oxide, which is vital for maintaining vascular health in the brain. This can lead to the accumulation of tau deposits, contributing to dementia and cognitive impairment.
