Q

What are the characteristics of REM sleep (25%)?

A

Loss of motor tone, increased brain O2 use, and variable pulse and blood pressure; when dreaming and penile/clitoral tumescence occur, EEG shows Beta waves.

Q

Which are the characteristics of night terrors?

A

Common in children, during the Non-REM slow-wave sleep (stage N3).

17
Q

Obstructive sleep apnea

A

Commonly in obese patients

18
Q

Narcolepsy

A

Patients true from Awake to REM sleep and skip the others stages.

19
Q

Which of the sleep disorders can not be diagnosed until 5 years of age?

A

Nocturnal enuresis.

20
Q

What drugs can be used in nocturnal enuresis?

A

1) Imipramine: TCA, decreases stage N3, Short-term use only.
2) Desmopressin (DDAVP): orally, decreases urination.
3) Indomethacin: Decreases renal blood flow.

21
Q

Sleep patterns in depression

A

Decreases slow wave sleep and increases REM and REM latency.

22
Q

Which are the sleep stages?

A

1) Awake (eyes open).
2) Awake (eyes closed).
3) Non-REM sleep (N1,N2 and N3).
4) REM sleep.

23
Q

Treatment for Insomnia: Melatonin

A

Non-addictive, OCT, vivid dreams, safe for

24
Q

Treatment for Insomnia: Valerian

A

OTC herbal remedy, studies show no benefit.

25
Q

Treatment for Insomnia: Antihistamines (Benadryl, Tylenol PM, Doxylamine).

A

Commonly used by patients first-line, associated with poor sleep quality, not for long-term use, anticholinergic side effects (avoid in the elderly).

26
Q

Treatment for Insomnia: Trazodone

A

Antidepressant, increase REM sleep, small risk of priapism.

27
Q

Treatment for Insomnia: TCA’s (aminotriptiline, doxepin)

A

Antidepressants, small risk of Arrhythmias (obtain EKG prior to use), anticholinergic side effects (avoid in the elderly).

28
Q

Treatment for Insomnia: Long acting benzodiazepines (temazepan, lorazepam, clonazepam, diazepam, chlordiazepoxide).

A

Addictive, short-term only (

29
Q

Treatment for Insomnia: Zolpidem (ambien), zaleplon (sonata)

A

Act at the benzo receptor, short-term only (

30
Q

Treatment for Insomnia: Ezoplicone (lunesta)

A

May be used long-term (FDA 2004)

31
Q

Treatment for Insomnia: Ramelteon (Rozerem)

A

Non-addictive because it works at melatonin receptors instead of GABA/benzo receptors; long-term studies are lacking.

32
Q

What is the treatment for narcolepsy?

A

Avoidance of drugs that cause sleepiness, scheduled naps (once or twice a day for 10-20min), stimulants-modalities is first line, support group attendance, if cataplexy then use venlafaxine, fluoxetine, or atomoxetine, Sodium oxybate (GHB) can assist in sleep and reduce cataplexy.

33
Q

What EEG waveforms correspond to the different stages of sleep?

A

Awake eyes open (Beta), Awake eyes closed (Alpha), N1 (theta), N2 (K complexes), N3 (Delta) and REM sleep (Beta)

34
Q

What drugs are used to shorten stage N3 sleep?

A

Imipramine and benzodiazepines

35
Q

What is the sleep pattern in a patient with narcolepsy?

A

Rapidly transition from the Awake state to REM sleep

36
Q

In what stage of sleep are night terrors found?

A

Non-REM sleep: Stage N3

37
Q

How long occurs the REM sleep?

A

Every 90 minutes
