Vascular risk factors appear to have a negative synergistic effect with amyloid beta levels in the brain, researchers report. The study suggests a combination of increased vascular risk and higher amyloid levels in the brain can predict more rapid cognitive decline during aging.
Two new studies from researchers at USC provide fresh insight into Alzheimer's risks. Researchers say attending college can stave off dementia and help retain memories in old age. Additionally, researchers report reducing diabetes and hypertension after 50 could increase longevity in people with Alzheimer's disease.
Researchers report middle aged people expressing cardiovascular risk factors, including diabetes and high blood pressure, have an increased risk of developing dementia later in life.
Researchers have identified nine risk factors during different stages in life that may increase a person's likelihood of developing dementia. At least 35% of dementia cases, researchers say, may be directly linked to these risk factors. By taking steps to reduce risks and by improving education, it is estimated that the incidence of dementia can be reduced by as much as 20%.
A new study reports a connection between slowed walking speed and cognitive decline appears to arise in the right hippocampus. Researchers recommend older people may benefit if their doctors measure their walking speed and check for changes over time, which could be an early indicator of impending cognitive decline.
A new study reports midlife vascular risk factors are associated with elevated levels of amyloid beta in later life.
Researchers report people who reported hypertension onset during their 80's were 42 percent less likely to develop dementia after the age of 90 than those with no history of high blood pressure.
Researchers successfully used electroacupuncture to increase the gene expression of enkephalins and reduce blood pressure for three days.
A new study reports high blood pressure in middle age may lead to cognitive impairment and could be a risk factor for Alzheimer's disease.
