New test could detect Alzheimer’s disease 3.5 years before diagnosis – study

While Alzheimer’s affects the formation of new brain cells in the hippocampus during the early stages of the disease, previous research has only been able to study neurogenesis in its later stages through post-mortem examinations

A new test could detect Alzheimer’s disease three and a half years before it is diagnosed, a new study suggests.

The new research from the Institute of Psychiatry, Psychology & Neuroscience (IoPPN) at King’s College London has established a blood-based test that could predict the risk of the condition.
