Awake, eyes closed
Stg1: light sleep
Stg2: deeper sleep, bruxism
Stg3-4: deepest non-REM sleep. sleepwaking, night terrors, bed-wetting/enuresis. slow wave sleep
REM: dreaming, loss of motor tone, memory processing, penile tumescence (erection), increased O2 use by brain

A

1: theta
2: sleep spindles and K complexes
3-4: delta (slow wave- lowest frequency, highest amplitude)
REM: beta

Awake/alert - beta
Awake w eyes closed- alpha
(if you count beta and alpha beforehand): BATS Drink Blood at night

70
Q

71
Q

Which stage is reduced by NE?

A

REM

NE is a stimulant

72
Q

Stg 3-4 + REM is 50% of the total sleep time

77
Q

REM sleep

A 
Increased and variable pulse during REM
Also increased and variable BP
Penile/clitoral tumescence
Occurs every 90min, increasing duration throughout night.
ACh is the main NT
REM decreases w age

REM is like sex: increased pulse, tumescence, decreases with age

78
Q

Narcolepsy

A

Disordered regulation of sleep-wake cycles
May include hypnaGOgic (GOing to bed) or hypnopoMic (Morning, just before awakening) hallucinations
Sleep episodes (both nocturnal and narcoleptic) start with REM.

Strong genetic component

79
Q

Cataplexy

A

Feature of narcolepsy

Loss of all muscle tone following strong emotional stimulus (often laughter)

80
Q

Rx for narcolepsy

A

avoid drugs that cause drowsiness
scheduled naps
stimulants- modafinil is 1st line; amphetamines
support group
if cataplexy: venlafaxine, fluoxetine, atomoxetine- used for ADHD
Sodium oxybate (GHB) can help reduce cataplexy

81
Q

Circadian rhythm

A

SCN of hypothalamus controls ACTH, prolactin, melatonin, nocturnal NE rls.
SCN –> NE rls –> pineal gland –>melatonin.
SCN is regulated by light.
Retina (not having light) stim’s SCN

82
Q

Sleep Terror Disorder

A

Periods of terror with screaming in middle of night.
Occurs during slow-wave sleep (stg 3-4), usu in kids

A

Can’t be dx’d until 5yo (developmental, not just chronological)
Usu wait until 7yo to treat

84
Q

How is enuresis treated?

A

First line- behavioral:
toilet training
motivational therapy (star chart)
restrict fluid before bed
night time chaperone, night light, scheduled waking
enuresis alarm pad- classic conditioning. mist effective long-term therapy

2nd line: drugs (but high likelihood of recurrence when you stop)
Imipramine for short term- decreases stg 4
Desmopressen (DDAVP)- anti-diuretic. used to be intranasal but that caused seizures (retain water, so decreased Na+, so seizure)
Indomethicin suppository- decrsd renal bld flow, so decrsd GFR, so decrsd urine
