Anxiety and depression have increased to heart breaking amount during the pendemic. We tend to see that by targeting some of the brain networks that deal with emotion and emotion regulation, we can get a nice effect on anxiety in depressed people. One of the other groups it's been really interesting for us early on, is affecting memory. With people who were recently diagnosed with dementia, we can move the needle very slightly on memory. Now that's pretty incredible, because with dementia, memory's always going down. It's a downward trend.
