It could take a mere 30 seconds to spot signs of Alzheimer’s disease in 40 year-olds in the near future say scientists who are developing a new diagnostic test. Usually Alzheimer’s disease is detected much later in life after the symptoms begin to appear.
Within the next two years, those at risk of the disease later in life could be detected using this test that can be carried out in a GP’s surgery which may become as simple and widely available as a blood pressure check. In 2006, there were 26.6 million sufferers worldwide. Alzheimer's is predicted to affect 1 in 85 people globally by 2050. It is expected that this number could double in the next generation.
The scientists have found that the early signs of the disease comes in the form of damaged brain cells and those found to have the damage may be able to take preventative measures which include changing their diet and doing more exercise in order to prevent the disease. Early treatment for these susceptible individuals is also possible.
According to lead researcher Professor David Bunce of Brunel University in London, these results have opened new avenues for screening, timely detection and intervention. He explained that early intervention could also prevent or delay the onset of the disease. “Although we cannot be certain that these middle-aged people will go on to get dementia, the results are important,” Bunce said.
The study is published in the journal PLoS One. According to The Alzheimer's Association the disease has no cure and the average sufferer dies within eight years of exhibiting symptoms.
