general sleep

Question 1

waves

Answer 1

B awake
A drowsy
T stage 1
S stage 2
D stage 3+4
REM saw tooth

1. delta (< 4Hz): sleep stages 3 and 4; dominant wave in infants up to one year
2. theta (4–8Hz): daydreaming, meditation; abnormal in awake adults, but normal in children up to 13, stage 1.
3. alpha (8–12Hz): alert but not actively processing information
4. beta (13-30Hz): dominant during alert and eyes open
5. gamma (>30)Hz): higher level information processing

Question 2

DM associated with?

Answer 2

i. diabetes is associated with restless legs syndrome, obstructive sleep apnea

Question 3

depression

Answer 3

k) premature loss of deep (slow wave) sleep
l) an increase in nocturnal arousal / awakenings
f) a reduction in total sleep time
g) increased phasic rapid eye movement (REM) sleep, and
h) increased core body temperature
decreased REM latency
increased sleep latency

Question 4

Ssri in sleep

Answer 4

Increase rem latency
But decrease sleep efficiency, rem, slow wave
Increase awakened

Exception: maybe Zoloft

Question 5

Trazodone in sleep

Answer 5

Increases slow wave sleep
Decreases rem
Through blocking 5ht2 receptors

Question 6

depression sleep changes

Answer 6

premature loss of deep (slow wave) sleep
an increase in nocturnal arousal / awakenings
a reduction in total sleep time
increased phasic rapid eye movement (REM) sleep, and
increased core body temperature
increased sleep latency
decreased REM latency
