Crazy how this study demonstrates that higher IGF-1 is associated with multiple-domain cognitive impairment. I personally have extremely low IGF (~80 ng/ml) without rHGH. When I am not taking HGH my memory declines, cognitive horsepower decreases sharply, and creativity is diminished. When I am consistently on my prescription of 2 IU HGH daily, my cognitive function is excellent. I have not had time to read through this study thoroughly, but just from the abstract it would seem that this study would suggest the opposite to be true, as my IGF-1 was lower my cognitive function should be higher. Perhaps I am interpreting it incorrectly.
