64. Covid-19, Sense of Smell and the Brain w/ Mark Albers Follow the Science

Covid-19 has some weird long-term effects, including prolonged inability to taste or smell, and various neurological symptoms – difficulty concentrating, memory loss and crushing fatigue. Alzheimer’s Disease is also connected to changes in smell and ability to remember smells. My guest, neurologist Mark Albers of Massachusetts General Hospital will help explain what all this means. 

We talk about how to interpret a brain scanning study showing brain “shrinkage” in people who’d had Covid; How inflammation in the brain might have something to do with changes in smell and long Covid; How he’s devised a smell test that picks up risk of early Alzheimer’s Disease, and whether there’s any reason to be concerned that Covid-19 will increase the risk for dementia.
