Tool allows GPs to assess Alzheimer's risk in over 65s
A new tool may allow GPs to assess the risk of Alzheimer's disease in people aged over 65.
3,375 patients with no evidence of dementia at baseline were followed up by a team at the university of California at San Francisco for six years.
Researchers allocated a points on a dementia risk index for older age, poor cognitive test performance, BMI, alcohol consumption and several other physiological factors.
4% of subjects with scores of between zero and three developed dementia over 6 years compared with 23% of subjects who score between four and seven and 56% of subjects with a score higher than eight.
Lead researcher Dr Deborah Barnes, assistant professor in psychiatry said: ‘The tool could identify people who have no signs of dementia but should be monitored closely.'
The study is published in Neurology this week.
