Hypothetical updated Jack model of AD biomarkers to include the role of brain vasculature.

Breakdown of blood vessel lining is seen in multiple neurodegenerative diseases. USC scientists say Alzheimer’s could be diagnosed earlier if scientists focus on an early warning within the brain’s circulation system. That’s important because researchers believe that the earlier Alzheimer’s is spotted, the better chance there is to stop or slow the disease.

“Cognitive impairment, and accumulation in the brain of the abnormal proteins amyloid and tau, are what we currently rely upon to diagnose Alzheimer’s disease, but blood-brain barrier breakdown and cerebral blood flow changes can be seen much earlier,” said Berislav Zlokovic, the Mary Hayley and Selim Zilkha Chair in Alzheimer’s Disease Research...

Resveratrol, given to Alzheimer’s patients, appears to restore the integrity of the blood-brain barrier, reducing the ability of harmful immune molecules secreted by immune cells to infiltrate from the body into brain tissues. The reduction in neuronal inflammation slowed the cognitive decline of patients, compared to a matching group of placebo-treated patients with the disorder. The laboratory data provide a more complete picture of results from a clinical trial studying resveratrol in Alzheimer’s disease that was first reported in 2015. The new findings will be presented at the Alzheimer’s Association International Conference 2016 in Toronto on July 27th.

The Alzheimer’s disease brain is damaged by inflammation, thought to be due to a reaction to the buildup of abnormal proteins, inclu...
