Biological ageing is not tied absolutely to chronological ageing and it may be possible to slow biological ageing and even reduce the possibility of suffering from age related diseases such as dementia. Also protective are a healthy diet, low to moderate alcohol intake, and regular exercise. But, it is not all negative, higher levels of education or occupational attainment may act as a protective factor. Genetics, neurotransmitters, hormones, and experience all have a part to play in brain ageing. This may be an attempt to compensate and recruit additional networks or because specific areas are no longer easily accessed. Memory decline also occurs with ageing and brain activation becomes more bilateral for memory tasks. As our vasculature ages and our blood pressure rises the possibility of stroke and ischaemia increases and our white matter develops lesions. As we age our brains shrink in volume, particularly in the frontal cortex.

Ageing has its effects on the molecules, cells, vasculature, gross morphology, and cognition. The effects of ageing on the brain and cognition are widespread and have multiple aetiologies.
