Interesting stuff.
I think that infection (such as influenza or measles) during pregnancy is also a risk factor for some brain disorders.
I can’t help but think that we are selecting for and against certain traits with our use of modern medicine.
For example, premature babies now survive who would have died even 50 years ago, meaning that whatever traits they carry which cause them to be premature are not eliminated from the gene pool. Abortion, on the other hand, is actively removing those whose genetic configurations allow them to override maternal instinct (and what else do those genes being weeded out do?). IVF is allowing infertile couples to reproduce despite genetics that should have prevented it; will the genetic configurations that cause infertility eventually become so prevalent that couples who can reproduce naturally become aberrations?
I won’t say that modern medicine is bad, but I wonder what we are doing to the gene pool with some of the practices.
Sad that something like strep throat can leave a lifetime of mental illness.
Of course we look back and blame ourselves - but of course when no symptoms are shown - what else could we have done?
