Sleep -Wake Disorders Flashcards
Insomnia Disorder
A.
A predominant complaint of dissatisfaction with sleep quantity or quality, associated with one (or more) of the following symptoms:
Insomnia Disorder
1.
Difficulty initiating sleep. (In children, this may manifest as difficulty initiating sleep without caregiver intention.)
Insomnia Disorder
2.
Difficulty maintaining sleep, characterised by frequent awakenings or problems returning to sleep after awakenings. (In children, this may manifest as difficulty returning to sleep without caregiver intervention.)
Insomnia Disorder
3.
Early-morning awakening with inability to return to sleep.
Insomnia Disorder
B.
The sleep disturbance causes clinically significant distress or impairment in social, occupational, educational, academic behavioural, or other important areas of functioning.
Insomnia Disorder
C.
The sleep difficulty occurs at least 3 nights per week.
Insomnia Disorder
D.
The sleep difficulty is present for at least 3 months.
Insomnia Disorder
E.
The sleep difficulty occurs despite adequate opportunity for sleep.
Insomnia Disorder
F.
The insomnia is not better explained by and does not occur exclusively during the course of another sleep-wake disorder (e.g., narcolepsy, a breathing-related sleep disorder, a circadian rhythm sleep-wake disorder, a parasomnia).
Insomnia Disorder
G.
The insomnia is not attributable to the physiological effects of a substance (e.g., drug of abuse, a medication).
Insomnia Disorder
H.
Coexisting mental disorders and medical conditions do not adequately explain the predominant complaint of insomnia.
Insomnia Disorder
Specify if:
With non-sleep disorder mental comorbidity: including substance use disorders
With other medical comorbidity
With other sleep disorder
Specify if:
Severity
Episodic: Symptoms last at least 1 month but less than 3 months.
Persistent: Symptoms last 3 months or longer.
Recurrent: Two (or more) episodes within the space of 1 year.
Note: Acute and short-term insomnia (i.e., symptoms lasting less than 3 months but otherwise meeting all criteria with regard to frequency, intensity, distress, an/or impairment) should be coded as another specified insomnia disorder.
Hypersomnolence Disorder
A.
Self-reported excessive sleepiness (hypersomnolence) despite a main sleep period lasting at least 7 hours, with at least one of the following symptoms:
Hypersomnolence Disorder
1.
Recurrent periods of sleep or lapses into sleep within the same day.
Hypersomnolence Disorder
2.
A prolonged main sleep episode of more than 9 hours per day that is nonrestorative (i.e., unrefreshing)
Hypersomnolence Disorder
3.
Difficulty being fully awake after abrupt awakening.
Hypersomnolence Disorder
B.
The hypersomnolence occurs at least three times per week, for at least 3 months.
Hypersomnolence Disorder
C.
The hypersomnolence is accompanied by significant distress or impairment in cognitive, social, occupational, or other important areas of functioning.
Hypersomnolence Disorder
D.
The hypersomnolence is not better explained by and does not occur exclusively during the course of another sleep disorder (e.g., narcolepsy, breathing-related sleep disorder, circadian rhythm sleep-wake disorder, or a parasomnia).
Hypersomnolence Disorder
E.
The hypersomnolence is not attributable to the physiological effects of a substance (e.g., a drug of abuse, a medication)
Hypersomnolence Disorder
F.
Coexisting mental and medical disorders do not adequately explain the predominant complaint of hypersomnolence.
Hypersomnolence Disorder
Specify if:
With mental disorder, including substance use disorders
With medical condition
With another sleeping disorder
Hypersomnolence Disorder
Specify if:
Acute: Duration of less than 1 month.
Subacute: Duration of 1-3 months.
Persistent: Duration of more than 3 months.
Hypersomnolence Disorder
Specify current severity
Specify severity based on a degree of difficulty maintaining daytime alertness as manifested by the occurrence of multiple attacks or irresistible sleepiness within any given day occurring, for example, while sedentary, driving, visiting with friends, or working.
Mild: Difficulty maintaining daytime alertness 1-2 days/week.
Moderate: Difficulty maintaining daytime alertness 3-4 days/week.
Severe: Difficulty maintaining daytime alertness 5-7 days/week.
Narcolepsy
A.
Recurrent periods of irrepressible need to sleep, lapsing into sleep, or napping occurring within the same day. These must have been occurring at least three times per week over the past 3 months.
Narcolepsy
B.
The presence of at least one of the following:
Narcolepsy
1.
Episodes of cataplexy, defined as either (a) or (b), occurring at least a few times per month:
Narcolepsy
a.
In individuals with long-standing disease, brief (seconds to minutes) episodes of sudden bilateral loss of muscle tone with maintained consciousness that are precipitated by laughter or joking.
Narcolepsy
b.
In children or in individuals within 6 months of onset, spontaneous grimaces or jaw-opening episodes with tongue thrusting or a global hypotonia, without any obvious emotional triggers.
Narcolepsy
2.
Hypocretin deficiency, as measured using cerebrospinal fluid (CSF) hypocretin-1 immunoreactivity values (less than or equal to one-third of values obtained in healthy subjects tested using the same assay, or less than or equal to 110 pg/mL). Low CSF levels of hypocretin-1 must not be observed in the context of acute brain injury, inflammation, or infection.
Narcolepsy
3.
Nocturnal sleep polysomnography showing rapid eye movement (REM) sleep latency less than or equal to 15 minutes, or a multiple sleep latency test showing a mean sleep latency less than or equal to 8 minutes and two or more sleep-onset REM periods.
Narcolepsy
Specify whether:
Narcolepsy without cataplexy but with hypocretin deficiency:
Criterion B requirements of low CSF hypocretin-1 levels and positive polysomnography/multiple sleep latency test are met, but no cataplexy is present (Criterion B1 not met).
Narcolepsy
Specify whether:
Narcolepsy without cataplexy but without hypocretin deficiency:
In this rare subtype (less than 5% of narcolepsy cases), Criterion B requirements of cataplexy and positive polysomnography/multiple sleep latency test are met, but CSF hypocretin-1 levels are normal (Criterion B2 not met).
Narcolepsy
Specify whether:
Autosomal dominant cerebellar ataxia, deafness and narcolepsy
This subtype is caused by exon 21 DNA (cytosine-5)-methyltransferase-1 mutations and is characterised by late-onset (age 30-40 years) narcolepsy (with low or intermediate CSF hypocretin-1 levels), deafness, cerebellar ataxia, and eventually dementia.
Narcolepsy
Specify whether:
Autosomal dominant narcolepsy, obesity, and type 2 diabetes:
Narcolepsy, obesity, and type 2 diabetes and low CSF hypocretin-1 levels have been described in rare cases and are associated with a mutation in the myelin oligodendrocyte glycoprotein gene.
Narcolepsy
Specify whether:
Narcolepsy secondary to another medical condition:
This subtype is for narcolepsy that develops secondary to medical conditions that cause infections (e.g., Wipple’s disease, sarcoidosis), traumatic, or tumbrel destruction of hypocretin neutrons.
Narcolepsy
Specify current severity:
Mild: Infrequent cataplexy (less than once per week), need for naps only once or twice per day, and less disturbed nocturnal sleep.
Moderate: Cataplexy once daily or every few days, disturbed nocturnal sleep, and need for multiple naps daily.
Severe: Drug-resistent cataplexy with multiple attacks daily, nearly constant sleepiness, and disturbed nocturnal sleep (i.e., movements, insomnia, and vivid dreaming).
Obstructive Sleep Apnea Hypopnea
A. Either (1) or (2):
1.
Evidence by polysomnography of at least five obstructive apneas or hypoapneas per hour of sleep and either of the following sleep symptoms:
Obstructive Sleep Apnea Hypopnea
1.a.
Nocturnal breathing disturbances: snoring, snorting/gasping, or breathing pauses during sleep.
Obstructive Sleep Apnea Hypopnea
1.b.
Daytime sleepiness, fatigue, or unrefreshing sleep despite sufficient opportunities to sleep that is not better explained by another mental disorder (including sleep disorder) and is not attributable to another medical condition.
Obstructive Sleep Apnea Hypopnea
2.
Evidence by polysomnography of 15 or more obstructive apneas and/or hypopnea per hour of sleep regardless of accompanying symptoms.
Obstructive Sleep Apnea Hypopnea
Specify current severity:
Mild: Apnea hypopnea index is less than 15.
Moderate: Apnea hypopnea index is 15-30.
Severe: Apnea hypopnea index is greater than 30.
Central Sleep Apnea
A.
Evidence by polysomnography of five or more central apneas per hour of sleep.
