Four key predictors of dementia identified

Australian researchers have identified four core risk factors for dementia in older people with normal cognition.

Their study followed more than 870 cognitively normal Sydney residents aged 70 and over for six years, during which around 10% developed dementia and 13% died.

They found that along with increasing age, factors predicting a dementia diagnosis included the following:

  1. Mild cognitive impairment at baseline
  2. Poorer smelling ability
  3. Slower walking speed
