Taking an SSRI? Read this

SOTD (study of the day):

Antidepressants of the future may work not on boosting serotonin, as SSRIs do, but on blocking a substance called GSK3ß in the brain. (OK, I had to copy and paste to get that funny little symbol at the end of the string of letters and numbers. I know it's Greek, but what is it?)

Pretty cool to think there's lots of room for improvement on the mental health front.
