I remember the exact moment I started taking my cognitive changes seriously. I was mid-sentence in a conversation I had initiated — about something I knew inside out — and the word I needed simply vanished. Not slowed. Vanished. I stood there for a full five seconds feeling completely unlike myself. And then the familiar, unwelcome question: is this something serious? It took me a while to understand what was actually happening — and longer still to distinguish what was hormonal and transitional from what needed a different kind of attention. This list is organised around everything I found in that process: the supplements that address the actual mechanisms, the lifestyle tools that support the brain during perimenopause, and the resources that helped me track my own patterns and stop catastrophising. Everything here has earned a place on my shelf.
