Boost Memory with Scents: A Neuroscientific Approach

The strong connection between scents and memories is widely. Has inspired many works of literature. However not as widely acknowledged is the potential of scents to improve memory retention and slow down aging in older adults. A recent study conducted at the University of California published in the Frontiers in Neuroscience journal shed light on this aspect. The study involved 43 adults, aged 60 to 85 who were divided into two groups. One group served as a control while the other group experienced pleasant smells released from diffusers for two hours every night.

After six months the second group showed a 226% improvement in memory tests. Additionally there were changes observed in certain brain regions suggesting possible enhancements in cognitive abilities. The authors of the study emphasized that aging often leads to a decline in sensitivity to smells which could be an indication of cognitive decline. Therefore creating an environment, with odors could be a preventive measure.
