Study Notes

Dyssomnias

Characterized by problems related to sleep quantity, quality, and timing
Examples of disorders classified under Dyssomnias: Insomnia, Narcolepsy, Obstructive Sleep Apnea (OSA), Breathing-related sleep disorders

OSA: Obstructive Sleep Apnea
Characterized by blockage of the upper airway during sleep
Can result in reductions in blood oxygen levels (desaturation)

Narcolepsy

Key characteristic: excessive daytime sleepiness
Common symptom: excessive daytime sleepiness
Triggers sleep episodes: cataplexy (sudden muscle weakness)
Diagnostic criteria: narcoleptic sleep episodes occur at least 3 times a week for 3 months or more
Key symptom: cataplexy
Characteristic feature: sudden muscle weakness (cataplexy)
Diagnostic test: Multiple Sleep Latency Test (MSLT)
Estimated prevalence in the general population: 0.02-0.18%
Prevalence: not equal across males and females
Factor believed to have a significant role in development: genetic predisposition
First-line treatment: modafinil
Recommended psychological/behavioral intervention: sleep hygiene practices
Intervention to manage emotional responses: cognitive-behavioral therapy (CBT)

Idiopathic Hypersomnia

Common symptom: excessive daytime sleepiness
Term to describe unrefreshing naps: "unrefreshing hypersomnia"
Presence of Sleep-Onset REM (SOREM) episodes: less common than in narcolepsy

Obstructive Sleep Apnea (OSA)

Characteristic: blockage of the upper airway during sleep
Result of blockage: reductions in blood oxygen levels (desaturation)
Diagnostic criteria: 5 or more events per hour of sleep
Blood oxygen level range for mild OSA: 90-94%
Normal range for blood oxygen levels (oxygen saturation) in adults: 95-100%
Untreated OSA can be a causal factor for: cardiovascular disease, hypertension, stroke
Not a common sign or symptom for OSA diagnosis: insomnia
Diagnostic criteria for OSA based on PSG evidence: 15 or more events per hour of sleep
Alternative diagnostic criteria for OSA based on PSG evidence: 5 or more events per hour of sleep regardless of daytime symptoms
Estimated percentage of population with OSA: 2-4%
More commonly affected gender: males
Factor associated with higher risk of developing OSA: excess body weight
Excess body weight relation to OSA prevalence: higher risk
Primary function of a Continuous Positive Airway Pressure (CPAP) machine: maintains airway pressure to prevent blockage
Individuals with OSA that CPAP therapy is often considered primary treatment for: those with moderate to severe OSA
Goal of motivational interviewing in OSA management: improve CPAP adherence
"Graduated exposure to work with CPAP difficulties" in OSA management: gradually exposing patients to CPAP difficulties to build tolerance.
