Many people would be surprised what depression feels like, and how much influence it has on cognitive abilities. The hippocampus is very involved with attention, focus, and memory and it atrophies with depression. Sometimes depression can cause pseudo-dementia which looks just like dementia except it's fixed just like depression.(One persons IQ fell from 130 to 70, and rebounded up to 115 after being treated with anti-depressants.) You are doing a lot of stuff. Just reading about it stressful. And just because you don't feel sad I wouldn't rule out depression. If you do have depression then when you slow down in life, and take an SSRI you'll find that you're memory starts improving dramatically and you'll feel like your old self. If that doesn't work then the other option is seeing a neurologist and getting a very expensive battery of tests with the very probably outcome "Hmm you seem fine".
