Relevant quote: Guanfacine, one of the two drugs tested in this trial, is designed to strengthen prefrontal cortex connections and protect against inflammation and stress. While originally developed to treat ADHD, it is being used to treat other conditions associated with prefrontal cortex dysfunction, and studies show that the drug is effective in restoring executive functioning and memory. NAC, the second medication, is a robust antioxidant and anti-inflammatory agent that can also be used to treat this neural region.
