COVID-19 vaccination may enhance hippocampal neurogenesis in adults

 Since we need all the neurogenesis help we can get, this is good news.

Highlights

•

The COVID-19 infection has a detrimental impact on hippocampal neurogenesis in adults.

•

In contrast, the existing literature supports an enhancing effect of COVID-19 vaccination on hippocampal neurogenesis.

•

The COVID vaccine-induced hippocampal neurogenesis may protect against age-related cognitive decline and mental disorders.

Abstract

Emerging evidence suggests a detrimental impact of COVID-19 illness on the continued hippocampal neurogenesis in adults. In contrast, the existing literature supports an enhancing effect of COVID-19 vaccination on adult hippocampal neurogenesis. Vaccines against respiratory infections, including influenza, have been shown to enhance hippocampal neurogenesis in adult-age animals. We propose that a similar benefit may happen in COVID-19 vaccinated adults. The vaccine-induced enhancement of the hippocampal neurogenesis in adults thus may protect against age-related cognitive decline and mental disorders. It also hints at an added mental health benefit of the COVID-19 vaccination programs in adults.
