A new study by the University of California, Irvine, challenges the long-held belief that cardiovascular conditions like high blood pressure and diabetes increase the risk of brain damage in older adults. The research suggests a more complex relationship between blood pressure, vascular health, and brain aging.
A study led by the University of California, Irvine has found cardiovascular conditions such as high blood pressure and diabetes, which are known to contribute to brain blood vessel damage in younger populations, not to be associated with an increased risk of such harm in individuals 90 and older.
The work, published online today in the journal Alzheimer's & Dementia: The Journal of the Alzheimer's Association, suggests that the relationship among blood pressure, vascular health and brain aging is more complex than previously thought. \\\'For decades, we've known that factors like high blood pressure and diabetes can injure blood vessels in the brain, increasing the risk for cognitive decline and dementia. However, our research found that these patterns may change as people age,' said corresponding author Dr. Ravi Rajmohan, UC Irvine clinical instructor of neurology. Even more intriguing, the use of blood pressure-lowering medication in this 90-plus group was linked to a lower likelihood of specific types of brain damage.' Dr. Ravi Rajmohan, Clinical Instructor, Neurology, University of California - Irvine \\\Team members analyzed the relationship between cardiovascular-related changes in the brain and self-reported vascular risk factors or use of heart-related medications by examining data from 267 participants in the National Institute on Aging's 90+ Study, one of the largest and most comprehensive research projects on the oldest-old population. They applied statistical models that accounted for age, sex and education and found that the presence of brain changes was not linked to traditional risk factors like high blood pressure or diabetes. In addition, they discovered that certain medications showed potential proactive effect

Indirect Brain Damage to Thalamus Contributes to Stroke Disability, Study FindsA recent study from Simon Fraser University researchers reveals how damage to the thalamus, a brain region that regulates crucial functions, contributes to long-term disability after a stroke. Even though the thalamus itself wasn't directly damaged, researchers found it was affected months or years after a stroke, potentially leading to new therapies.
