Breathing-Related Sleep Disorders

Breathing-Related Sleep Disorder

During normal sleeping: the muscles in the upper airway relax during sleep, constricting the passageway somewhat and making breathing a little more difficult.

Breathing-Related Sleep Disorder

hypoventilation (breathing may be labored) or sleep apnea (short periods (10 to 30 sec) when one stops breathing

Breathing-Related Sleep Disorder

Loud snoring, heavy sweating during the night, morning headaches

Obstructive sleep apnea hypopnea syndrome, Central sleep apnea, Sleep-related hypoventilation

Three types of apnea

Obstructive sleep apnea hypopnea syndrome

Airflow stops despite continued activity by the respiratory system

Obstructive sleep apnea hypopnea syndrome

Obesity, night snoring, MDMA (ecstasy), common in males

Central sleep apnea

Complete cessation of respiratory activity for brief periods

Central sleep apnea

Associated with certain central nervous system disorders

Central sleep apnea

Wake more often at night but no daytime sleepiness

Sleep-related hypoventilation

decrease in airflow without a complete pause in breathing

Sleep-related hypoventilation

Increase CO2

Circadian Rhythm Sleep-Wake Disorders

A persistent or recurrent pattern of sleep disruption that is primarily due to an alteration of the circadian system or to a misalignment between the endogenous circadian rhythm and the sleep-wake schedule required by an individual's physical environment or social or professional schedule.

Circadian Rhythm Sleep-Wake Disorders

The sleep disruption leads to excessive sleepiness or insomnia, or both.

Circadian Rhythm Sleep-Wake Disorders

The sleep disturbance causes clinically significant distress or impairment in social, occupational, and other important areas of functioning

Delayed sleep phase type

A pattern of delayed sleep onset and awakening times, with an inability to fall asleep and awaken at a desired or conventionally acceptable earlier time. (late matulog)

Advanced sleep phase type

A pattern of advanced sleep onset and awakening times, with an inability to remain awake or asleep until the desired or conventionally acceptable later sleep or wake times. (maaga matulog)

Irregular sleep-wake type

A temporally disorganized sleep-wake pattern, such that the timing of sleep and wake periods is variable throughout the 24-hour period.

Shift work type

Insomnia during the major sleep period and/or excessive sleepiness (including inadvertent sleep) during the major awake period associated with a shift work schedule (i.e., requiring unconventional work hours).

Episodic

(Circadian Rhythm Sleep-Wake Disorders) Symptoms last at least 1 month but less than 3 months.

Persistent

(Circadian Rhythm Sleep-Wake Disorders) Symptoms last 3 months or longer.

Recurrent

(Circadian Rhythm Sleep-Wake Disorders) Two or more episodes occur within the space of 1 year
