Yes to atherosclerosis, not too much about nootropics. It's a fantastic course, available from the Stanford school of continuing studies. It was a two full days weekend seminar taught by a neuropsychologist who works at the Stanford Hospital. I'm not an alumni and anyone can register for these course so I really, really recommend it!

I'm a young guy (31) but the class was so cool. People from ages 25 to 90 year old Stanford alum.
