Sleep study

Hey. A couple of weeks ago I spent the night at a sleep clinic. I had the follow-up appointment with the specialist today. I have mild sleep apnea when I sleep on my back, so I'm going to lose some kilos and get a painful shoulder sorted so I can sleep on my side more.

This is fascinating stuff. Once I've finished with Pain and its environs (Cancer pain, Total pain (yes, there is such a topic), Psychology of pain, and a few others) I'm determined to find out what I can about the cognitive effects of sleep deprivation. You don't know a killer resource for that do you? A textbook or recent review by a super expert? --Anthonyhcole (talk) 13:03, 22 August 2011 (UTC)

Let me think and maybe ask around. There's lots of research on the cogn. effects of (each of the stages of) sleep including naps. Napping is in. Hordaland (talk) 15:23, 22 August 2011 (UTC)

It's in? I thought I was just being old. --Anthonyhcole (talk) 15:43, 22 August 2011 (UTC)

Sara Mednick does naps. Bob Stickgold is one expert on cognition and sleep; see his faculty profile and a couple of videos. Here is a Finnish paper you may have seen, as it is cited in Sleep deprivation. That's some tips. I'm asking a friend, as well. Hordaland (talk) 19:28, 22 August 2011 (UTC)

I don't think there is much to be gained by looking for recent sources. The cognitive effects are so salient that they've been known for a long time: at moderate levels of deprivation difficulty in sustaining attention, difficulty in sustaining physical effort, slowed reactions and difficulty with motor coordination; at higher levels loss of pleasure in food or sex or whatever, gastrointestinal distress, and jitteryness; at the highest level overt hallucinations and uncontrollable obsessive thought patterns.

I'd like to know if impulse inhibition, emotion regulation and working memory have been tested. One assumes so, since the US military show an interest. And maybe pain threshold and tolerance (though they're not exactly cognition). --Anthonyhcole (talk) 15:52, 23 August 2011 (UTC)

(outdent) Good modern sources: For sleep deprivation, the go-to guy would be David F. Dinges. He co-wrote the chapter on sleep deprivation in Principles and Practice of Sleep Medicine (along with his colleague Siobhan Banks). A good review by him would be this one; it covers much of the same ground as the book chapter. Here is an important study of his on the genetics of response to sleep deprivation. One of his most recent studies shows that it takes more than one night of 10 hours recovery sleep to recuperate. A mathematical study. More in PubMed under Dinges DF.

Charles A. Czeisler also touches on the subject from time to time. David R Thorne of Walter Reed Army Medical Center has done good work.

(Stay away from Jim Horne. Once upon a time he did good work. ... Fortunately it seems no one else cites him any more.) Hordaland (talk) 15:34, 23 August 2011 (UTC)

Wow. What an information cornucopia. Thanks to both of you. Don't know when I'll get to this. I think I'm going to have to start prioritising better. Sweet dreams. --Anthonyhcole (talk) 15:46, 23 August 2011 (UTC)

Here's another useful article by a different group on possible neuron loss due to sleep deprivation. Hordaland (talk) 15:53, 23 August 2011 (UTC)

Thank you. --Anthonyhcole (talk) 17:43, 23 August 2011 (UTC)
