Cognition, the senses, and the risks that turn out to be modifiable.
- Circadian disruption and ageing: what the human studies supportmixedThe mechanism is settled and the exposure definitions are not. A 2017 review of 26 studies says so in its own limitations section.
- Cognitive decline and the modifiable risksgoodAround 45% of dementia risk is attributable to fourteen factors, most of them ordinary.
- Creatine and the aging brainmixedA real but small memory effect, concentrated in the group that has been studied least.
- Hearing lossgoodA midlife risk factor with a device-shaped solution that most people delay for years.
- Hearing loss and cognitive decline: what 50 cohorts and one randomised trial showmixedThe association is among the largest in the sensory determinants of brain ageing. The intervention trial is the more important paper, and it is the one that came out flat.
