I'm 41, and you are describing me to a tee. I had surgery about 4 years ago, and was under for less than an hour. The language issues, writing and spelling, etc. Most importantly for me is that writing software has gotten a lot more difficult. I attributed it to aging, but after reading some of this research, I'm questioning that. It feels like the issues have popped up in the last several years. However... I feel like this is how we got into the false causal relationship between autism and vaccines. Kids get a lot of vaccines in the first 4 years of life, and are diagnosed with autism then as well. So, you work backwards from a diagnosis and say, "oh the problems started a few weeks after the 3 year check-up, and they got shots, so the shots caused it!!" I would be worried we are doing the same here. There is likely cognitive decline in men in their late 30s due to stress from work and kids, lack of sleep, reduced activity + weight gain, etc. We also get colonoscopies (or other procedures) around then as well. So, it is easy to say, "well I started having memory problems a few years ago, right around the time I had a hernia repair under general anesthesia, so they MUST be related."
