Fecal transplants could one day be used as a therapy to restore cognitive function in the elderly—according to new research from the University of East Anglia, the University of Florence and the Quadram Institute.

A new study published today shows how fecal transplants from older to younger mice altered their gut microbiome, which in turn impacted their spatial learning and memory.

The research team hope that reversing the procedure could one day see fecal transplantation used to combat cognitive decline among the elderly.
