You still know the word, understand the task and have years of experience behind you. Yet suddenly the word disappears, your train of thought breaks, or something that once felt automatic takes far more effort.

During perimenopause, hormone changes, poor sleep, hot flashes, stress, fatigue and everyday pressure can all pile up at once. Together, they can contribute to what we call The Neural Efficiency Loss™ — where your brain becomes less efficient at finding information, holding onto it and using it quickly when you need it.

The information may still be there. Your brain can simply have a harder time getting to it. That’s why you can know exactly what you want to say — but still go blank. Or start a task — then forget what you were doing. It isn’t just “forgetfulness.” It’s a brain that no longer feels as quick, reliable or effortless as it used to.
