Reducing Cognitive Decline Risk: What the Evidence Supports

There is a reasonably well-developed evidence base on modifiable dementia risk, and it looks very different from what the supplement aisle suggests.

The modifiable factors

The Lancet Commission on dementia prevention identified a set of modifiable risk factors estimated to account for a substantial share of dementia cases, including less education in early life, hearing loss, hypertension, obesity, smoking, depression, physical inactivity, social isolation, diabetes, excessive alcohol, traumatic brain injury, air pollution, and more recently untreated vision loss and high LDL cholesterol. These are population-level estimates and individual risk varies considerably.

The unexpected ones

Hearing loss is among the more surprising entries and among the larger contributors in the model, with hypothesis that reduced auditory input increases cognitive load and reduces social engagement. Hearing aid use is being actively studied. Air pollution exposure has accumulating evidence. Cardiovascular risk factors feature heavily, reinforcing the observation that what protects the vascular system protects the brain, which makes blood pressure control one of the higher-value interventions available.

How supplements compare

Poorly, on current evidence. Large randomised trials of multivitamins, B vitamins, vitamin E, omega-3 and ginkgo for cognitive decline prevention have largely produced null or inconsistent results in well-nourished populations. This is not a claim that nutrition is irrelevant - correcting genuine deficiency matters - but it does mean that treating blood pressure, addressing hearing loss, staying physically active and maintaining social connection have a stronger claim on your attention than any capsule.
