|
stage of sleep characterized by:
alpha replaced by slower rhythms slow horizontal eye movements begin "startles" (bilateral symmetric muscle movements) |
stage 1 sleep
|
|
|
stage of sleep characterized by:
EEG slowing to theta bursts of "sleep spindles" - burst of faster high voltage waves k-complexes (high amplitude negative deflection follwoed by a positve wave) |
stage 2 sleep
|
|
|
stage of sleep characterized by:
EEG slowing to delta (appear first in the occipital region) First stage where you feel like you have slept |
stage 3 sleep
|
|
|
stage of sleep characterized by:
60% or more of EEG in all regions of the brain in the delta range |
stage 4 sleep
|
|
|
stages of sleep that represent deep sleep ("slow wave sleep")
these stages are associated w/ restful sleep, and are required to reduce 'sleep deficit' and daytime somnolence |
stages 3 and 4 sleep
|
|
|
EEG (amplitude and velocity)in wakefulness, N-REM sleep, and REM sleep
|
Waking: low/fast
N-REM sleep: high/slow REM sleep: low/fast |
|
|
length of the typical sleep cycle, I-IV?
|
90 minutes
|
|
|
difference between the first sleep cycle and the rest
|
the first usually does not include a REM period
|
|
|
sleep characterized by fast, darting, irregular conjugate eye movements
it resembles the waking state physiologic effects include flaccid paralysis of skeletal muscle and erection of penis and clitoris most dreaming occurs here |
**REM sleep
|
|
|
difference in the deprivation of deep sleep and REM sleep
|
deep sleep: daytime somnolence, decreased alertness, increased "microsleeps"
REM sleep: decreased attention and concentration, decreased short term memory (>36hr), delirium (>96hr) |
|
|
A person is woken up from sleep and denies being asleep at all, what stage of sleep where they in?
|
Stage I
|
|
|
In which stage of sleep do you have no muscle tone?
|
both REM and Non-REM
|
|
|
REM and memory
|
During REM see neuronal activity in the mesial temporal lobes which resembles waking short term memory formation seen during the previous day
|
|
|
What happens as total sleep time increases?
|
Cycles become shallower; less time in stages III and IV
More slow-wave sleep during early hours of sleep than later portion |
|
|
AGING and sleep?
|
Sleep cycles become shallower
less deep sleep, total sleep time and cycles per night. Also have more frequent awakeneings. end up w/ mental and terminal insomnia |
|
|
How is mood affected during sleep deprivation VS sleep satiation?
|
Dep - Euphoric...resembles mania
Sat - Dysphoric...resembles depression |
|
|
DIMS
|
disoders of the:
intiation and maintance of sleep |
|
|
DOES
|
Disorder of
Excessive Somnolence |
|
|
Abnormalities of sleep architecture and REM function?
|
parasomnias (e.g night terrors, nightmares, somnambulism (sleep walk) and somniloquia (talking in sleep)
|
|
|
Most common sleep complaint, associated w/ aging and poor sleep habits?
|
Simple insomnia
|
|
|
Transient insomnia results from...?
What is the tx? |
Anticipation (anxiety)
BEST indication for very short term use of hypnotics |
|
|
If you want to help prevent sleep-shifting from jet lag what should youdo?
|
less disruptive to the sleep cycle if the cycle is advanced and you go to bed later and get up later.
|
|
|
Patient present w/ sleep attacks, catplexy (sudden loss of skeletal muscle), Sleep paralysis (head is awake but not the body), hypnopomic/hypnogogic hallucinations, dx?
|
Narcolepsy
|
|
|
Peripheral Vs Central sleep apnea
|
peripheral - airway obstruction
Central - CO2 insensitivity (have periods when they are not breathing then gasp because breathing is driven by hypoxia or O2) |
|
|
Tx for chronic (simple sleep) insomnia?
|
Sleep hygeine
|
|
|
Tx of sleep apnea
|
C-PAP
|
|
|
Tx of middle and terminal insomnia?
|
Treat depression
|
|
|
Tx of Narcolepsy
|
Diagnose carefully, use stimulatnts
|
