What sleep disorders are covered in this episode and why are they often overlooked?
Hi everyone, welcome back to the Think You Mind Podcast. I'm Anya. I'm a psychiatry registrar working in South London. I'm very excited to welcome back Dr. Hugh Selsic, who is a consultant psychiatrist working in sleep medicine. Dr. Selsick's been involved in sleep medicine for nearly 30 years. He founded and ran the insomnia and behavioral sleep medicine at UCLH and previously worked at the sleep disorder centres at Guys and St. Thomas's hospital in central London. Today we talk about the sleep disorders occurring where people struggle with having too much sleep. We talk about people who experience difficulties with strange experiences during their sleep, like nightmares, sleep paralysis, sleep walking, sleep eating, sleep sex.
If you're interested, keep listening, and you should get a really good overview of these different things. different disorders, how they can be treated, and things to look out for both in terms of yourself, but also if you're a clinician. working with people who have difficulties with their sleep, the kinds of things that may often get missed. But if you've got a inquisitive mind and if you're aware of what to look out for, you might pick up something that could be quite life-changing. Dr. Salzik, thank you so much for coming back and joining us again. Thank you for having me. So when we met last time, and I'll refer people back to that episode, we spoke mostly about insomnia. We touched on a lot about what insomnia is, what the kinds of treatments for it are, what you tell people to think about when they come to you with insomnia.
But when we started to touch on a little bit about sleep a bit more broadly, Broadly. And I remember you telling us that in terms of what people come to you when it relates to sleep problems, it's sort of broadly split into categories of I can't sleep enough, I'm sleeping too much, or sort of weird things are happening when I sleep. And so I'm hoping today we can focus on that other side. So the sleeping too much or weird things happening, and start to get a sense for For what people come to you with, what you do, how you think about these disorders, what is happening in the brain with them. So
So certainly for some of them it w is useful just to look under the hood of sleep a little bit and look at the different types of sleep, the different sleep stages that we have. For for most of human history, we imagined sleep was just a thing. Uh it was a singular thing. And it was very often seen as a negative, uh as a kind of a a lack of wakefulness, if you like. And it's really only in the last seventy years or so that we've really been able to have a look at what's going on in the brain and the body during sleep, and we've come to realize that sleep is a collection of different states, uh, which are kind of mashed together. So we broadly divide sleep up into two types: rapid eye movement or REM sleep, and everything else that we call non-REM sleep.
And non-REM sleep is further divided up into three different stages, stage one, two, and three. Stage one is just a very light stage is k kind of a halfway house between being awake and asleep and we don't think it has any function of its own. Stage two sleep is a light, again, a light stage of sleep, but we spend half the night in the stage, and it seems to be really important for uh memory consolidation, uh, for cognitive function. And stage three sleep is our deep sleep. And this is the most unconscious you will be in normal life. It's very hard to wake someone up from stage three sleep. Um, again, it seems to play an important role in memory consolidation and consciousness. cognitive function, but we are now seeing um indications that it's it's probably very important as well for physical repair of the brain and uh possibly also uh of the body.
So those are different stages of sleep. And we're when we're thinking about sleep disorders, it's useful to have those in mind because Certain disorders will arise from certain states of sleep. And we cycle through these different stages in nine 90-minute cycles through the night.
