Neurology- Sleep Physiology And Sleep Disorders

Front 1

What are some neurological consequences of sleep deprivation?

Back 1

IRRITIBILITY, apathy, decr working memory, impaired exec funxn, slowed cog speed, impaired learning

Front 2

What are some metabolic consequences of sleep deprivation?

Back 2

Elevated BP, impaired glc handling, increased body fat

Front 3

What occurs in stage 1 of sleep?

Back 3

impaired thinking, amnesia

Front 4

What are some pathologic findings and other occurances of stage 2 sleep?

Back 4

light, non-dreaming sleep w/ low arousal threshold, startle jerks, and periodic mvmnts. Due to resp rhythm instability (central) and decr upper airway dilator tone (obstructive) can have apneas

Front 5

What are some pathologic findings and other occurances of stage slow wave?

Back 5

deep, non-dreaming sleep associted w/ high arousal threshold, mental slowness & incoordination on wake, irrational behavior. Has low epileptic siezure threshold and can have confusion arousals

Front 6

What are some pathologic findings and other occurances of REM sleep?

Back 6

Dreaming sleep w/ hallucinations. Can have hypoxia if restrictive or COPD. REM behavior disorder can occur

Front 7

What does polysomnography recordings help diagnose?

Back 7

sleep-disorder breathing syn, narco, periodic leg mvmnt disorder, NREM confusional arousals, REM behavior disorder

Front 8

How much and when do narcoleptics usually fall asleep?

Back 8

Sleep in sedentary, monotonous, non-threatening situations. Sleep total of around 8 hrs but in short naps

Front 9

What are some common findings w/ narcos sleep?

Back 9

sleep paralysis during transition to sleep, sleep hynogogic hallucinations in transition, cataplexia

Front 10

What is the pathophysiology and neurophysiology of narcolepsia?

Back 10

abnormal control of wakefulness and REM sleep. due to loss of hypocretinergic neurons resulting in instability of sleep switch
