A new angle of Alzheimer\u2019s research is being investigated.

Biomarkers are a molecule found in blood, other body fluids, and tissues that are an indicator of an abnormal process, condition, or disease, and could be a tell-tale sign of Alzheimer\u2019s.

Otago University Researcher Dr Ashleigh Barrett-Young says that while there are several biomarkers could indicate Alzheimer\u2019s, it\u2019s still unknown whether there is a single one \u2014or several\u2014 that are good indications in the pre-clinical or undiagnosed population.

She says that a majority of Alzheimer\u2019s research has been done on those already showing symptoms, and while this is still useful information, if someone is already showing symptoms they don\u2019t need a biomarker to tell them they have the disease.
