Memory is more than recollection but also a reflection of who we are. It connects us to the people we love, the places we've been, and the stories that shape our lives.

Alzheimer's disease threatens those connections, gradually eroding memory and cognition. It develops gradually, often years before symptoms become obvious. But while the disease remains one of the greatest challenges of our time, growing scientific understanding is opening new doors for earlier detection, better treatment and more effective prevention.

In this episode of Health Talk, Dr. Zhang Wei, director of the Center for Cognitive Neurology at Beijing Tiantan Hospital affiliated with Capital Medical University, explains how to spot the early warning signs of Alzheimer's disease, and shares the latest insights into screening, treatment and everyday habits that support long-term brain health, offering a useful guidance and hope for protecting our cognitive ability.
