A groundbreaking study published in Acta Neuropathologica has identified a genetic variant that can reduce the risk of developing Alzheimer’s disease by up to 70%. This variant appears to help in removing toxic amyloid from the brain through the blood-brain barrier, highlighting the significant role that blood vessels in the brain may play in Alzheimer’s disease. These findings could pave the way for new therapeutic approaches to prevent or treat Alzheimer’s disease. “Alzheimer’s disease may get started with amyloid deposits in the brain, but the disease manifestations are the result of change…
