There are plenty examples of people who spend every day in hours of intense, uninterrupted deep thought. At my university math department there are, for example, professors who will be working with a pen and paper on a single problem for 9+ hours uninterrupted. According to this doctor, those guys probably should have died from a brain hemorrhage at age 30.
Working deeply for hours on end every day will rewire your brain a bit, which is what LA himself confirms in the blog post, but damage it? No shot.
The stress and anxiety people can experience from poker are for sure mentally damaging, but that is not what the doctor is saying. He says that the cognitive strain itself of playing poker is what is damaging and will literally cause a stroke, which I do not see how it can possibly be true. Not the long periods of inactivity, the stress, or a shitty diet - the cognitive load of poker. The brain is not a muscle, you can't work it to death. Seems he is a doctor specializing in concussions; probably a case of everything's a nail?
Also, mass tabling poker does not put your brain in "overdrive". You are still making individual decisions at any given time. Multitasking is a myth. And LA's assertion that 15 tabling poker is akin to playing 15 video games at once is extremely misguided. It's similar to playing 15 chess games at once, which won't make your brain work any harder than if you playing a single chess game at the same level of focus.
