I had similar issues - brain fog, difficulty concentrating and forgetfulness. I've discovered that, for me at least, it's all about lifestyle and nutrition, especially the oils and nutrients that the brain needs. I've completely reversed the situation and have wonderful mental clarity and focus and energy - it's really quite amazing how much more functional I am now.
No single factor solves the problem, at least for me.
I have to do ALL of the following to maintain this state:
- regular cardio - 4-5 times a week.
- cut out sugar and eat sensibly, i.e. 3 meals a day with lots of fresh fruit and veg and fibre - the idea is mainly to maintain good digestion and gut health, not so much weight loss. Foods that aid light and easy digestion use far less of your energy (and mental energy) than heavy meals.
- Omega oils and a range of supplements including vitamin B5/6/12, Acetyl-L-Carnitine etc etc, herbal extracts known to be beneficial to brain health (ginseng, ashwaganda, etc) and even a small dose of CBD oil daily.
- proper sleep, preferably 8 hrs
- drastically reduced alcohol consumption, especially binge drinking - now that I'm more aware I've found that even a fairly moderate evening with anything more than two beers negatively affects me for days afterwards.
If I drop the ball on any one of the above, the whole thing reverts. Trust me, if you're feeling like you're lost in a forgetful haze, barely getting through the day and unable to concentrate or focus, you will be amazed at what happens when you do these things. Barring anything else your outlook on life and motivation changes drastically as well. Once you experience this, you will not want to revert to where you were, or at least not for long.
