9
Q
How Other Creatures Sleep (4)
A
- length of sleep cycles vary among species
- roughly correlated with metabolic rate - faster metabolism=shorter sleep cycles
- Most animals have REM and NREM cycles
- Some only sleep one hemisphere at a time- while the other hemisphere remains alert
10

- causes clinically significant distress or impairment
- Not fully explained by a coexisting mental disorder
13
Q
Differentials to consider with sleep (3)
A
- Normal variations:
- age-related changes, situation variables - Circadian disturbances-late shift work, day-night reversals
- Medications, drugs or beverages
14
Q
Hypersomnolence Disorder (4)
A
- Excessive sleepiness despite adequate sleep (7 hours)
- Recurrent sleep periods during the day or slow awakening
- Three times per week for three months
- Not related to another sleep disorder to substance use
15
Q
Narcoplepsy
3 indicators
A
- Sudden and recurrent episodes of an irrepressible need to sleep during the day accompanied by 2 of the following:
A. Cataplexy- sudden loss of muscles tone with full consciousness, frequently precipitated by laughter
B. Hypocretin deficiency in CSF
C. Brief latency on EEG
16
Q
Cataplexy
A
- indicator for narcolepsy
Def. sudden loss of muscle tone with full consciousness, frequently precipitated with laughter
17
Q
Assoc. Features of Narcolepsy (5)
A
- Hazy-feel like automaton
- Vivid hypnogogic (falling asleep) or hypnopompic (awakening) hallucination
- Vivid dreams or nightmares
- Appears sleepy most of the time
- During episodes of cataplexy, reflexes abolished
***NOT due to lack of sleep, due to neurological disorder
18
Q
Hypnogogic Hallucination
A
falling asleep
19
Q
Hypnopompic Hallucination
A
Awakening
20
Q
Obstructive Sleep Apnea (2)
A
- on polysomnography: at least 15 episodes of apneas or hypopnea accompanied by snoring, gasping, or breathing pauses
- excessive daytime sleepiness, fatigue, or unrefreshing sleep
21
Q
Circadian Rhythm Disorders (4)
A
- Sleep disruptions due to misalignment between endogenous circadian rhythm and the person’s sleep-wake cycle
- frequently results from physical environment or social/ work schedules
- Leads to excessive sleepiness or insomnia
- Causes clinically significant impairment
22
Q
Parasomnias (2)
A
- Abnormal behavioral, experiential, or physiological events associated with sleep
- Associated with both REM or NREM sleep
23
Q
NREM Arousal Disorders (2)
A
- Assoc. with incomplete awakening, usually during the first 1/3 of sleep cycleA. Sleepwalking: rising from bed, walking around, staring gaze, minimally responsive, difficult to awakenB. Sleep terrors: abrupt awakening in terror, usually crying out, signs of intense fear, minimally responsive
- minimal recollection for dreams or events during episode
24
Q
REM Sleep Disorder
A
- Repeated episodes or arousal during sleep with vocalizations or complex motor behaviors
- Usually occur in last part of sleep cycle, 90 minutes or so after sleep onset
- Upon awakening, person becomes completely alert and not confused or disoriented
- Polysomnography revelas REM sleep without atonia
- May occur in parkinson’s disease or other motor system diseases
25
Restless Leg Syndrome (2)
How often/how long?

C. Worse in, or exclusive to, evening or night
2. At least 3x a week for 3 months
26
Alcohol and sleep (3)
1. induces somnolence quickly followed by wakefulness, vivid dreams, and restless sleep
2. Reduced NREM sleep, and increased REM sleep
3. Light, fragmented sleep may persist long after sobriety is established in chronic users
27
Sexual Disorders (3)
1. Functional Disorders
2. Gender Dysphoria

5. Sexual sadism d/o
6. Pedophilia
7. Fetishistic d/o
8. Transvestic
31
Voyeuristic Disorder
Paraphilic Sexual Disorder
arousal from observing an unsuspecting person naked or engaging ins sex
32
Exhibitionist Disorder
Paraphilic Sexual Disorder
arousal from exposing one's genitals to an unsuspecting person
33
Frotteuristic Disorder
Paraphilic Sexual Disorder
arousal from touching or rubbing against a non-consenting person
34
Sexual Masochism Disorder
Paraphilic Sexual Disorder
arousal from being humiliated or being made to suffer
35
Sexual Sadism Disorder
Paraphilic Sexual Disorder
Arousal from inflicting physical or psychological suffering on another person
36
Pedophilia
Paraphilic sexual disorder
arousal from fantasies or actions involving prepubescent children
37
Fetishistic Disorder
Paraphilic Sexual Disorder
arousal from use or focus on nonliving objects or non-genital body parts
38
Transvestic Didorder
Paraphilic Sexual Disorder
arousal from cross-dressing
39
Fantasies and Arousal (3)
1. Paraphilias involve both fantasies and actions
2. involvement in these activities causes distress, interpersonal difficulties, and legal problems
3. Sexual fantasies tend to increase in complexity over time, with arousal or climax more difficult to reach without elaboration of fantasies
40
Sexual Fantasy Issues
increase in complexity over time, makes arousal and climax more difficult to reach without elaboration of fantasies
