Risk 2.5 times greater for those with multimorbidity at age 55, long-term study of 10,000 Britons reveals
Having two or more chronic health problems in middle age more than doubles the risk of dementia, according to a study that researchers say underscores the importance of good health earlier in life.
More than 900,000 people are living with dementia in the UK, and about 57 million people are affected globally. The worldwide toll is predicted to nearly triple to 153 million by 2050.
