A 30-second test to spot the signs of Alzheimer’s in those in their 40s is being developed by scientists. The simple procedure, which warns of the debilitating disease decades before symptoms show, brings the hope of routine screening for dementia in as little as two years. Carried out on a computer in a GP’s surgery, the test could become as widely used as blood pressure checks. Those found to have a tiny piece of tell-tale damage to their brains could take preventative measures such as changing their diet and taking more exercise. Quicker detection would allow earlier treatment and, with the help of new drugs, some who test positive might never develop the disease.
Alzheimer’s and other forms of dementia affect more than 800,000 Britons, with the number expected to double in a generation.
Professor David Bunce, who led the research, said: ‘The study lays open the possibilities for screening, early detection and intervention. The earlier we can intervene with people vulnerable to eventual dementia, the greater the chances of preventing or delaying the disease onset.’ At the moment, diagnosis is based on memory tests or expensive brain scans. Proof of the disease often comes only from examination of the patient’s brain after death.
By contrast, the computer procedure, based on a simple test of reaction times, would be quick and easy. Read more: dailymail.co.uk
