Social isolation is one of 14 modifiable dementia risk factors in the 2024 Lancet Commission. What large cohorts and the best trial actually show, why isolation and loneliness differ, the causation problem, and an eight-week plan for building connection.
The MIND diet made headlines with a ~53% lower Alzheimer’s figure — then a large trial couldn’t confirm it. Both are true. Here’s what the MIND diet is, where those striking numbers came from, why the trial diverged, and what a sensible person should actually do: eat it as sound, healthy nutrition, with realistic expectations.
The Lancet Commission ranks hearing loss as the single largest modifiable risk factor for dementia — yet it’s almost never part of the brain-health conversation. Here’s what the evidence actually shows, whether hearing aids slow decline, why the link exists, and the simple, overlooked action worth taking.
Ginkgo biloba is one of the most-tested brain supplements — which is exactly why the gap between its marketing and its evidence is so clear. The two big dementia-prevention trials failed, the healthy-adult memory boost is thin, and the “blood-thinner” scare is overstated. Here’s what the evidence really shows.
The Finnish sauna-dementia finding is real but observational — and while you’re actually hot, cognition tends to get worse. An honest look at what sauna use does for the brain, the likely long-term mechanism, and the safety cautions most articles skip.
Phosphatidylserine is the only nootropic with an FDA-qualified health claim for cognitive function — and the research behind that designation is more robust than most supplement categories. Complete guide: how PS maintains cell membrane integrity, reduces cortisol, improves memory formation, and the sourcing and dosing protocol that delivers results.
Chronic neuroinflammation — mediated by NF-κB activation and microglial overactivation — is a primary driver of Alzheimer’s pathology, cognitive ageing, and depression. Diet directly regulates these inflammatory pathways. The MIND diet reduced Alzheimer’s risk by 58% in the Morris 2015 study. Extra-virgin olive oil’s oleocanthal inhibits COX-1 and COX-2 via the same mechanism as ibuprofen. The gut-brain axis — through microbiome dysbiosis and intestinal permeability — delivers systemic inflammation to the brain. Understanding the mechanisms makes dietary choices more specific and evidence-based than any superfood list.
Most people taking magnesium are taking the wrong form for cognitive purposes. Magnesium L-Threonate is the only commercially available magnesium compound with documented ability to meaningfully raise brain magnesium concentrations — addressing the NMDA receptor gating mechanism that determines synaptic plasticity efficiency. The Liu et al. trial reversed approximately 9 years of age-related cognitive decline in 12 weeks. This complete guide covers the mechanism, the MIT Neuron publication, the Magtein® quality distinction, and why evening timing is mechanistically optimal.
