I very much doubt you'll see any fugitive enhancement and in the two decades I've been cycling on and off supplemental Creatine for my workout regime, I can't speak for any such gains.

Creatine is both synthesized by the body and consumed in meat. The vast majority of it goes into skeletal muscles where it functions as an ATP recycling compound, something these cells consume a lot of. Small amounts are found inn the blood and brain add well but not nearly as much.

It may provide a small boost if you're low on blood sugar simply from providing some extra energy and drawing water into the cell - but it's not much more than you would get from simply consuming energy rich compounds like sugars or carbohydrates. It does certainly provide significant physical performance enhancement by increasing endurance, reducing muscle fatigue and generally providing greater muscle "pump" from it's cell volumizing qualities. Thus I'd say that the only cognitive gains one would experience would be from the added satisfaction coming from better performance and improved physique - ie. A placebo effect of sorts. However, depending on the importance of physical fitness to an individual, this can be substantial. My improved workouts and increased strength definitely put me in a much better mood and provide greater motivation for my intellectual endeavors. Ironically, because it can supercharge workouts, it can leave one with substantial mental fatigue immediately after such workouts at which point you're better off taking a break to recover before doing any mentally intense stuff
