David Perlmutter MD
David Perlmutter is a thought leader in the area of functional medicine (FM) and neurology. In Brain Maker he focuses on optimization of brain function using functional medicine concepts. This is not a disease centered book but focuses on neurological function optimization. This is a great read for anyone, especially those who wonder what a focused FM approach in particular systems are would look like. The audible version comes with a companion PDF that has a brain optimization diet and meal planning.
