Alzheimer’s is not inevitable.
But for too long, the conversation has focused on reacting to disease rather than understanding what drives it.
After over a decade of diving into the research, I can confirm that the science tells a different story.
The processes that underlie cognitive decline often begin years, even decades, before symptoms appear, and many are influenced by metabolism, inflammation, immune activity, and lifestyle factors.
In my new book, Brain Defenders, I explore the emerging science of the brain’s immune system and what it means for prevention and long-term resilience.
I believe this conversation needs to change.
