Biomarker found to detect Alzheimer’s disease years before symptoms occur
A research team from Europe has found that cases of early onset Alzheimer’s are connected with increased levels of a certain biomarker in blood plasma, which could mean a simple blood test could diagnose types of Alzheimer’s disease before symptoms appear in patients in the future.
There are many forms of dementia with differing fundamental causes, including autosomal dominant familial Alzheimer’s disease (ADAD) which is defined by the presence of mutations in one of several specific genes. Although it is less common, only covering less than 1% of all Alzheimer’s cases, symptoms occur earlier in life than other forms of Alzheimer’s and thus it is a key concern for those more at risk of the disease.
