I have very mild sleep apnea. My in-lab study documented an AHI of only 5.2. (or something in the 5’s) However, I feel extremely tired and brain dead every day. I have been using a CPAP for a month with very minor and modest improvement.
My major puzzlement is how I could be this tired or be almost completely unable to focus and concentrate with such a low AHI. It almost makes me wonder if something else is wrong with me. It was noted that I had 25 PLMD movements per hour. That was slightly elevated but that isnt a very high number either.
