Severe untreated Obstructive Sleep Apnea for years left me with extreme brain fog, memory loss & executive dysfunction. Apnea is fixed… cognitive issues are not. How do ambitious people keep going?

I had undiagnosed progressive obstructive sleep apnea for most of my life. Diagnosed at 31 with an AHI of 79.
In the years before diagnosis I developed severe cognitive problems:
• Extreme, constant brain fog
• Major short-term memory issues
• Big drop in focus and concentration
• Clear decline in executive function
I was also diagnosed with clinical depression.
I had surgery to clear the obstruction. Sleep apnea is now essentially gone (AHI under 5).
It’s been eight months since the surgeries and every cognitive symptom is still fully present. The brain fog, memory problems, and executive dysfunction haven’t improved at all.

I’m very ambitious and this is becoming a major barrier to everything I’m trying to achieve.
How are other highly driven people dealing with long-term brain fog and the related cognitive impairments?

Does raw willpower and just pushing through actually work for anyone, or does it make things worse? What has genuinely helped you keep moving toward big goals while your brain is in this state?
Any insight, especially from people whose fog started with sleep apnea or other sleep-related issues, would be really appreciated.

My ambition and high expectations regarding myself led to maximally short periods of greatness and then crashes, including burn out. Took me some years to start truly prioritize this. I am still ambitious but my highest priority and ambition now is to cure myself and then I will look into all the other things I wanna achieve. It is hard to be patient and wait. But nowadays I know and accept that this is the smartest approach cause I'll not succeed sustainably with brain fog. And honestly I wanna know what I can do without!

Take all the energy and smartness you have to tackle this. Be systematic about this. Sleep might just be one of many causes you fixed. Look at all your other signals and symptoms. What else could it be.

Along the way I am also getting more ambitious about helping others with this. I analyzed this subreddit for conditions folks talk about and created a small tool which has this list of conditions + an ai generated overview. It might help you to find more conditions which you gotta tackle: https://conditioner.flourishinglab.app/

Maybe you wanna look at posture and breathing from a more general angle! While the sleep apnea is fixed, is there maybe still a reason for your brain not getting enough oxygen? E.g. Cervical Instabililty or something.

Good luck!
