Reading other PSG-MSLT results helped me make sense of mine, so I'm including mine.
PSG: Fell asleep in 18 minutes, went into REM in 96 mins, relatively normal sleep architecture - within normal for all sleep stages, except slightly elevated stage 2 sleep.
Total arousals: 141 or 21.9/hr (respiratory arousals: 10; LM arousals: 5; spontaneous: 126), 11 awakenings
No apneas, normal occasional hypoapneas, no significant periodic leg movements
Sleep efficiency "slightly reduced" at 89.7%, apparently due to my insomnia (life has to be a comedy to have both narcolepsy and insomnia). I was also formally diagnosed with delayed sleep phase syndrome (my PSG started at 11PM).
MSLT, 4 naps:
Mean sleep latency of 4 naps: 3 min (quickest: nap 2, asleep in 1 min; slowest: nap 4, asleep in 5.5 min)
REM occurred in all 4 naps, average latency 10 min from sleep onset (quickest: nap 2, 4 min; slowest: nap 1, 15.5 min)
Interesting to note: In nap 2 (where I fell asleep in 1 min), I had sleep paralysis and a hallucination halfway through. It was recorded as: went into REM after 4 mins asleep, stayed in REM for 4 minutes, brief arousal, then into n1 stage for 2 min, arousal (when I "pulled" myself out of sleep paralysis and woke up from the hallucination) for 1 min, n1 for 2 min, and back into REM for remainder of nap.
MSLT was rough. There was another patient, a teen boy, in the room across from me and he clearly did not have narcolepsy so they should have just sent him home immediately out of sensitivity for me . Here I am desperately trying to find the one corner of the room where the camera can't see me so I can sleep for just one second without getting caught. Meanwhile, he's laying in bed, watching cartoons like it would never put him to sleep, even though the bed is comfortable and warm and the cartoons can kind of sound like a lullaby if you close your eyes for one minute. When the tech asked for his sleepiness score, he replied, "Can I just say 0? I feel great."
At the end, they made me sign a paper saying that I would contact them if I decided to go on a road trip before my next appointment, and that I should probably refrain from operating any machinery in the meantime.
