Covid-19 patients who suffer from loss of smell show different activities in brain: Study

A study has found that people living with long Covid who suffer from loss of smell show different patterns of activity in certain regions of the brain. The study was published in the journal, 'EClinicalMedicine'.

The research used MRI scanning to compare the brain activity of people with long Covid who lost their sense of smell, those whose smell had returned to normal after Covid infection, and people who had never tested positive for Covid-19.
