This ontology aims to facilitate- the diagnostic procedure of sleep disorders
Enlarging or distending a structure, increasing its internal wall stress
An abnormal condition that affects the body's function but may or may not have specific signs and symptoms. Resulting from an organismic dysfunction that causes distress, disability, or disadvantage.
A condition characterized by excessive sleepiness, regardless of how much sleep is had.
A common sleep disorder that can make it hard to fall asleep or stay asleep. It also can cause you to wake up too early and not be able to get back to sleep.
Disruptive behaviors or events that affect your sleep. You might walk, talk or make physical movements to act out a dream.
A range of conditions that result in abnormal breathing during sleep.
A category of sleep disorder in which repetitive movements interfere with sleep.
Abnormal sleep-wake schedule or pattern associated with the CIRCADIAN RHYTHM which affect the length, timing, and/or rigidity of the sleep-wake cycle relative to the day-night cycle.
A physical or mental feature which is regarded as indicating a condition of disease, particularly such a feature that is apparent to the patient.
Emotional tension or energy characterized by unexplained feelings of apprehension, uneasiness or dread associated to an anticipated, actual or imagined stressor.
An emotional state characterized by feelings of sadness, emptiness, and/or tearfulness.
The affective response to an actual current external danger which subsides with the elimination of the threatening condition.
Level of moisture in the air, such as high or low humidity.
Level or amount of energy being emitted by either a natural (e.g. sun) or an artificial source of light.
The systematic and methodical manipulations of body tissues best performed with the hands for the purpose of affecting the nervous and muscular systems and the general circulation.
A state of consciousness in which the individual eliminates environmental stimuli from awareness so that the mind can focus on a single thing, producing a state of relaxation and relief from stress. A wide variety of techniques are used to clear the mind of stressful outside interferences. It includes meditation therapy.
Level or volume of auditory phenomenon determined by the amount of energy being generated, where high energy levels are perceived as loud sounds and low energy levels as soft sounds.
An unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage.
An intense itching sensation that produces the urge to rub or scratch the skin to obtain relief.
System of working in which people work one of a set of usually two 12-hour or three eight-hour shifts in a 24-hour period; designed to make use of the 24 hours of the clock, rather than a standard working day.
An empty area; an area set apart or available for use
The negative mental, emotional, and physical reactions that occur when environmental stressors are perceived as exceeding the individual's adaptive capacities.
A short sleep, usually during normal waking hours.
Degree of heat or cold, such as high and low temperature, normal or extreme temperature.
A circadian rhythm sleep-wake disorder in which sleep quality and duration are normal but sleep onset and wake times are earlier than desired or earlier than socially acceptable times.
A movement disorder that typically starts within the first 15 days of life, occurs during sleep, and consists of intermittent repetitive jerks of the limbs at two to three per second. It is often evoked by gently restraining the child. Benign sleep myoclonus of infancy is usually not associated with any other neurologic impairment and spontaneously subsides within the first year of life.
Central sleep apnea due to high altitude periodic breathing
Instability in the ventilatory system induced by altitude can lead to the development of periodic breathing and central apneas during sleep.
Central sleep apnea with Cheyne Stokes breathing
A form of periodic breathing, commonly observed in patients with heart failure
Episodes where you partially wake up from non-rapid eye movement (NREM) sleep with confusion and disorientation. You might mumble or stare off into space or be unable to respond when someone talks to you. Then, you’ll fall back to sleep.
Defined by a delay in the major sleep episode relative to desired or required sleep and wake times.
A benign sensory parasomnia characterized by the sensation of hearing a loud sound, such as an explosion or gunshot, during transitions between sleep and wakefulness. This sensation often leads to abrupt awakening, accompanied by distress but without significant pain.
Hypersomnia Associated With Psychiatric disorder
An excessive sleepiness that is not caused by a medical condition, substance use, or sleep disorder, but is instead associated with a mental health condition.
An excessive daytime sleepiness after getting a full night's rest.
Occurs 3 or more nights a week, lasts more than 3 months, and cannot be fully explained by another health problem.
Episodes of insomnia that last a few days at a time (less than 3 months)
A voluntary sleep disorder, meaning that it results from the choices that individuals make about sleeping rather than any underlying medical, emotional, or environmental cause.
Characterized by the relative absence of a circadian pattern in an individual’s sleep-wake cycle.
A temporary sleep problem that can affect anyone who quickly travels across several time zones.
An extremely rare condition that causes intermittent episodes where you sleep for long periods of time.
A chronic neurologic disorder, associated with uncontrollable sleep urges and cataplexy
A chronic neurologic disorder, associated with uncontrollable sleep urges but NO cataplexy
Defined by the repeated occurrence of nightmares that cause clinically significant distress or impairment in social, occupational or other important areas of functioning, which are not attributable to the physiological effects of a substance (e.g. drug abuse or medication) and which cannot be adequately explained by coexisting mental and medical disorders
A circadian rhythm sleep disorder in which an individual’s biological clock fails to synchronize to a 24-hour day.
A sleep disorder characterized by repeated episodes of complete (apnea) or partial (hypopnea) collapse of the upper airway, causing oxygen desaturation or sleep arousal
A childhood disorder in which there is upper airway dysfunction causing complete or partial airway obstruction during sleep leading to decreased oxygen saturation or arousals from sleep.
A sleep-related disorder in which respiratory effort is absent intermittently during sleep.
An unexplained episode of cessation of breathing lasting 20 seconds or longer, or a shorter respiratory pause associated with bradycardia, cyanosis, pallor, and/or marked hypotonia
Primary central sleep apnea of prematurity
A sudden cessation of breathing that lasts for at least 20 seconds or is accompanied by bradycardia or oxygen desaturation (cyanosis) in an infant younger than 37 weeks gestational age.
A rare disorder with repetitive, usually flexor arrhythmic brief jerks of the trunk, hips, and knees in a fixed pattern
Is parasomnia strongly linked to neurodegenerative diseases, and it can also be very disturbing and lead to injury requiring medical attention.
Is characterised by repeated episodes of sleep paralysis (a temporary inability to move or speak that occurs directly after falling asleep or waking up) , occurring independently of other sleep disorders.
A condition that causes a very strong urge to move the legs. The urge to move usually is caused by an uncomfortable feeling in the legs.
A condition that primarily affects people who work night, early morning, and rotating shifts for their jobs
Defined as the repetitive jaw muscle activity characterized by the clenching or grinding of teeth during sleep.
A non-rapid-eye movement parasomnia typified by recurrent episodes of eating/drinking following arousals, with associated partial/complete amnesia.
Seeing, hearing, feeling, or smelling something that isn't actually there while you're falling asleep or waking up

Sleep related rhythmic movement disorder
A neurological disorder characterized by repetitive movements of large muscle groups immediately before and during sleep. Occurs in both infants and children and rarely occurs or persists in adolescence or adulthood.
A common childhood parasomnia characterized by episodes of extreme terror and panic that occur suddenly out of NREM, slow-wave sleep.
Also known as Somnambulism, includes undesirable actions, such as walking, that occur during abrupt but limited arousals from non-rapid eye movement (NREM) slow-wave sleep.
A prevalent pediatric condition, characterized by involuntary urination during sleep at least twice a week for 3 months in children older than 5.
