[Publication] Effect of a Standardized Extract of Asparagus officinalis Stem (ETAS®50) on Cognitive Function, Psychological Symptoms, and Behavior in Patients with Dementia: A Randomized Crossover Trial


In this randomized, double-blind, placebo-controlled, crossover comparison pilot trial, 300mg ETAS50 intake per day for 12 weeks could reduce severity of symptoms, especially apathy and irritability, in patients with mild to moderate dementia.

This is the first paper which reports clinical improvement in dementia symptoms by ETAS intake. It is suggested that ETAS could improve the quality of life of dementia patients in the ageing society.

Further research is ongoing by adding objective evaluations like MRI and blood profiling to obtain a strong evidence to confirm the efficacy.
