What resilience means for a brain
Resilience is the capacity to maintain function under load and return to baseline afterward. For the brain, the load might be a poor night’s sleep, an infection, a surgery, a head impact or simply another decade of age. The systems that determine recovery are largely the same ones that run clearance: blood-vessel health, sleep architecture, metabolic regulation and the cellular recycling processes (autophagy and the proteasome) that break down damaged components inside cells.
The modifiable factors
The 2024 Lancet Commission on dementia estimated that about 45 percent of dementia cases worldwide are potentially preventable by addressing fourteen modifiable risk factors across the life course: less education, hearing loss, high LDL cholesterol, depression, traumatic brain injury, physical inactivity, diabetes, smoking, hypertension, obesity, excessive alcohol, social isolation, air pollution and untreated vision loss. Many of these act through blood vessels, inflammation or sleep, which is why they belong on a page about resilience.
The National Institute on Aging offers plain-language guidance on each of these for older adults, and the Canadian National Institute on Ageing video on this page summarizes them in three minutes.
Why engineering belongs here
Behavioural changes are powerful but hard to sustain, and some people, because of disease or circumstance, cannot sleep deeply or exercise vigorously. Part of NeuroClearance’s interest is whether well-designed, safe, inexpensive technology can support the same physiology that healthy habits support, for people who need the help most. That is a research direction, not a product promise.
