Kind of interesting. The changes with the more severe infections seems legitimate. I'm a little skeptical about the ones with smaller changes.

A .2 sd reduction is just 3 IQ points (varies slightly on which test/scale is used). That seems like a very small decrease to measure when only looking for markers to evaluate their previous IQ. Testing IQ in general is a fickle thing. I could take IQ tests back to back and have it vary by more than 3 points.
