Dr. Quanguang Zhang's lab focuses on understanding the effects of silent brain ischemia on Alzheimer’s dementia. They investigate how conditions like cardiac arrest and stroke, which often leave patients asymptomatic, can lead to long-term cognitive decline. The lab is exploring innovative treatments, such as pulsed laser therapy, to protect the brain and prevent Alzheimer’s disease in models that mimic these conditions. The goal is to uncover the biological mechanisms linking silent brain ischemia to Alzheimer’s, offering potential new therapies for at-risk patients.
