Your Vision Can Predict Dementia 12 Years Before a Diagnosis, Study Suggests

Two large studies in the UK and Australia found worse vision predicted higher dementia risk about 12 years later.

The UK study linked slower visual processing speed to later dementia but the tests could not predict individuals.

The Australian study of 2,281 people found worsening visual acuity predicted declines in memory, attention, and problem-solving, partly mediated by reduced social contact.
