What is brain age?
Brain age is an estimate of how old your brain appears to be functioning — based on modifiable lifestyle factors rather than your birth year. Research in neuroscience shows that sleep, exercise, diet, social connection, and mental stimulation all directly affect neuroplasticity, cognitive reserve, and the rate of brain ageing.
A brain age younger than your actual age means your lifestyle is preserving cognitive function. Older means certain habits may be accelerating decline — but these factors are reversible.
