REM søvn atferdsforstyrrelse; RBD. Årsak ukjent; kan skyldes degenerering av hjerneloci som er  involvert i aktiv inhibisjon av motorisk input til ryggmargen under REM-søvn. Komorbid med nevrodegenerative lidelser som Parkinson, Lewy-legeme demens, Downs syndrom,  multippel systematrofi, narkolepsi, multippel sklerose. RBD som første manifestasjon/predikativ av begynnende nevrodegenerativ lidelse. Symptomer kan utløses av medikamentell REM-suppresjon: SSRI, TCA, MAOi.

SLEEP - things not to do in bed: No Electronics - blue wavelengths mess with our natural melatonin production, making it harder to fall asleep. ____ Don't Toss and Turn - if you can't sleep, get out of bed and do something calming until you feel tired. Tip: read. ____ Don't Work - this teaches your brain your bed is for things other than sleeping. ____ Don't Snooze - set your alarm a little later and work on getting up rightaway, otherwise you're just interrupting your REM periods of sleep.

This pins goes more deeply into EEG brain wave patterns. Each stage is depicted with its correlated EEG. Each wave is different going from alpha waves to delta waves. And all changing drastically between stages.

Each sleep cycle is made up of several different stages of non-REM and REM sleep, the overall proportions of which are shown in this pie chart (image by Luke Mastin)

What are sleep cycles? If you'd like to learn about the different types and stages of sleep and how they affect you, we have the answers.

During REM sleep a sleepers brain waves demonstrate characteristics that are similar to waking sleep; a combination of alpha, beta, and desynchronous waves.

Chronic use of amphetamine/stimulants is associated with shortened sleep duration and REM suppression, which is due to the direct effects of the drugs releasing dopamine and noradrenaline in the brain. Adaptive homeostatic changes occur in the brain so that during the first 2 weeks of withdrawal there is a rebound of both of these. This leads to the clinical symptoms of daytime sleepiness and fatigue, plus the nocturnal effects of increased sleep duration and REM with vivid, unpleasant…

REM sleep is punctuated and immediately preceded by PGO (ponto-geniculo-occipital) waves, bursts of electrical activity originating in the brain stem. These waves occur in clusters about every 6 seconds for 1–2 minutes during the transition from deep to paradoxical sleep. They exhibit their highest amplitude upon moving into the visual cortex and are a cause of the "rapid eye movements" in paradoxical sleep.
