Pathology begins 20–30 years before symptoms. The 2024 Lancet Commission identified 14 modifiable risk factors accounting for ~45% of dementia cases worldwide. The window for prevention is the 40s and 50s, not the 70s.
Brain & Cognition
Memory and focus issues in adults under 65 are almost always physiological, hormonal, or lifestyle-driven — not early dementia. Hormones, blood sugar, sleep, inflammation, and nutrients shape cognition in ways that respond to targeted intervention.
Brain & Cognition
Mood and anxiety are frequently downstream of physiological dysfunction — hormones, blood sugar, thyroid, gut, inflammation, nutrients. The pattern of "treatment-resistant" depression often turns out to be physiologically-driven mood symptoms that haven't been investigated.
