Protecting Your Memory — A Practical Guide
What normal cognitive ageing actually looks like, what's really behind most memory concerns in midlife, and what the evidence says about reducing your long-term dementia risk.
What's inside
- What normal cognitive ageing actually looks like — what changes, what doesn't, and the clear difference between age-related slowdown and something worth investigating
- The common causes that aren't dementia — sleep deprivation, chronic stress, thyroid dysfunction, B12 deficiency, medication side effects, and perimenopause account for the majority of memory concerns in midlife
- The 12 modifiable risk factors for dementia identified by the Lancet Commission — including why hearing loss is the single largest midlife risk factor most people have never heard of
- Why sleep is a direct brain health intervention — the glymphatic system, amyloid clearance, and what chronic poor sleep is actually doing to the brain overnight
- Exercise and cognitive health — why aerobic exercise is the most powerful single modifiable factor for protecting memory, and how much you actually need
- Diet, inflammation, and the brain — what the evidence supports and what it doesn't, without the supplement industry noise
- How cardiovascular health and brain health are the same problem — and why the risk factors you're already managing for your heart matter just as much for your memory
- When to see a GP — clear signposts for what warrants investigation versus what doesn't, and how to have a useful conversation when you get there
Is this guide for you?
This guide is for anyone who has started noticing things — a name that wouldn't come, a word that hovered just out of reach, a parent who went through dementia and left a quiet fear about what that might mean for you. Those concerns deserve a direct response, not vague reassurance. The honest starting point is this: most memory changes in people under 70 are not early dementia. They are the downstream effects of sleep, stress, hormones, or other entirely modifiable causes — and addressing them frequently resolves the symptoms entirely. This guide tells you what is actually happening, what is worth acting on, and what the evidence says about protecting your cognitive health for the long term.

The Better Memory Bundle
Protecting Your Memory + Better Sleep Guide — sleep is when the brain clears the proteins associated with Alzheimer's. It is not just a symptom of cognitive decline — it is one of the most direct levers you have over it.
