New Lipid Biomarkers Identified for MCI

In a new study published in the journal Translational Psychiatry, researchers from Hokkaido University have identified promising biological markers that could help detect mild cognitive impairment (MCI), an early stage of dementia, in a simple and noninvasive way. The research team analyzed saliva, blood plasma, and fecal samples from participants aged 65–85 years with mild cognitive impairment and compared them with those of healthy individuals. They examined more than 200 lipid molecules and found clear differences in lipid composition across saliva, plasma, and fecal samples between healthy individuals and those with mild cognitive impairment.
