I'm sorry, I got my letters turned around. The test for narcolepsy is a MSLT (multiple sleep latency test). The reason that I had a sleep study was because I have Fibromyalgia & Chronic Fatigue Syndrome. I became so tired at the end of August that I ended up in the hospital. I was also being treated for severe depression & the Psychiatrist they assigned me didn't believe that Fibromyalgia & Chronic Fatigue were viable illnesses. He told me that most people who are diagnosed with those are more than likely suffering from lack of sleep. (duh!) He told me that I had symptoms of Narcolepsy because when I was younger I would have sleep paralysis, I got weak in the knees & will fall to the ground if I get frightened suddenly (like from when my hubby would wait for me around a corner & jump out at me), I go into mini sleep periods during certain activities (like the things you could do almost on auto pilot, e.g., driving a familiar route, unloading the dishwasher, etc..), I dream a lot & remember these dreams in vivid detail, sometimes upon falling asleep I see things that are not there (like a man peeking in my bedroom window) & I'm so fatigued that it has lessened the quality of my life. My test did turn out neg. but I'm not so sure that it was done correctly. The man that did the test had a severe neurological disorder & it affected his hands & speech. He never told me to go to sleep on the first test so I lay there about 10 minutes before I thought, OK, I think I'm supposed to go to sleep now. Usually they do an audio/visual test to make sure the leads & speakers are working. I guess at the end of this test they're supposed to say, "Good night" & he didn't until I asked him to clue me in. In the past 3 days I have remembered dreams after being woken up within 35 minutes. I'm on Concerta for my daytime sleepiness so I guess I'm being treated for Narcolepsy. I hope I explained this OK for you. :confused:
