A groundbreaking surgical trial at Changi General Hospital in Singapore is testing a novel approach to treating Alzheimer's disease. The two-year study, called Cervical Lymphatico-Venous Bypass for Alzheimer's Disease (CLyVeB-AD-1), involves connecting lymphatic structures in the neck to veins to enhance the brain's natural waste clearance system.
The procedure targets the lymphatic system, which normally removes metabolic waste from the brain during deep sleep. Four patients aged 61 to 73 with mild to moderate Alzheimer's have undergone the microsurgical technique. Early results show improvements in memory loss, cognitive function, and behavioral issues. Brain scans reveal steady improvements at six months.
Singapore has approximately 100,000 people living with dementia, with 70% having Alzheimer's disease. Current medications only slow progression modestly. This surgical intervention represents the first regulated clinical trial of its kind in Southeast Asia.
