A study led by Research Professor Matej Orešic from VTT Technical Research Centre of Finland suggests that Alzheimer’s disease is preceded by a molecular signature indicative of hypoxia and up-regulated pentose phosphate pathway. This indicator can be analysed as a simple biochemical assay from a serum sample months or even years before the first symptoms of the disease occur. In a healthcare setting, the application of such an assay could therefore complement the neurocognitive assessment by the medical doctor and could be applied to identify the at-risk patients in need of further comprehensive follow-up.

Alzheimer’s disease (AD) is a growing challenge to the health care systems and economies of developed countries with millions of patients suffering from this disease and increasing numbers of new cases diagnosed annually with the increasing ageing of populations.
