Researchers at Johns Hopkins Medicine say they have significant new evidence of a relationship between reduced sense of smell and risk of developing late-life depression in a study that followed over 2,000 community-dwelling older persons for eight years.
In the neurons that our noses utilise to detect smell, scientists at Umea University in Sweden have found a previously unidentified cellular component called an organelle. The discovery may spur more studies into the COVID-19 symptom of poor smell perception.
