The presence of formic acid in urine detects early-stage Alzheimer's
The presence of formic acid in urine can reveal the presence of Alzheimer's disease at an early stage, a new study reveals.
The study was published in the journal Frontiers in Aging Neuroscience.
Scientists found that urinary formic acid is a marker of cognitive decline that can indicate the very early stages of Alzheimer's disease.
The study included 574 participants, either healthy or suffering from Alzheimer's at various stages of progression, analyzed their urine and blood, and underwent psychological assessments.
The research found that people with Alzheimer's disease have significantly higher levels of formic acid in their urine, and the amount of this substance increases as the disease progresses.
Alzheimer's disease can develop many years before symptoms of full-blown, irreversible dementia appear.
