Biochemical signature predicts progression to Alzheimer's disease

A study led by Research Professor Matej Orešič 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.
