Eating and Sleep Disorders Flashcards
Eating disorder involving recurrent episodes of uncontrolled excessive (binge) eating followed by compensatory actions to remove the food (for example, deliberate vomiting, laxative abuse, and excessive exercise).
bulimia nervosa
Relatively brief episode of uncontrolled, excessive consumption, usually of food or alcohol.
binge
Eating disorder characterized by recurrent food refusal, leading to dangerously low body weight.
anorexia nervosa
Pattern of eating involving distress-inducing binges not followed by purging behaviors; being considered as a new DSM diagnostic category.
binge-eating disorder
BED
Excess of body fat resulting in a body mass index (BMI, a ratio of weight to height) of 30 or more.
obesity
In the eating disorder bulimia nervosa, the self-induced vomiting or laxative abuse used to compensate for excessive food ingestion.
purging techniques
Consuming a third or more of daily food intake after the evening meal and getting out of bed at least once during the night to have a high-calorie snack. In the morning, however, individuals with night eating syndrome are not hungry and do not usually eat breakfast. These individuals do not binge during their night eating and seldom purge.
night eating syndrome
Surgical approach to extreme obesity, usually accomplished by stapling the stomach to create a small stomach pouch or bypassing the stomach through gastric bypass surgery.
bariatric surgery
Periodic intervals of sleep during which the eyes move rapidly from side to side, and dreams occur, but the body is inactive.
rapid eye movement (REM) sleep
Problems in getting to sleep or in obtaining sufficient quality sleep.
dyssomnias
Abnormal behaviors such as nightmares or sleepwalking that occur during sleep.
parasomnias
Assessment of sleep disorders in which a client sleeping in the lab is monitored for heart, muscle, respiration, brain wave, and other functions.
polysomnographic (PSG) evaluation
Small electronic device that is worn on the wrist like a watch and records body movements. This device can be used to record sleep–wake cycles.
actigraph
Percentage of time actually spent sleeping of the total time spent in bed.
sleep efficiency (SE)
Short, seconds-long periods of sleep that occur in people who have been deprived of sleep.
microsleeps
Condition in which insufficient sleep interferes with normal functioning.
insomnia disorder
Difficulty in initiating, maintaining, or gaining from sleep; not related to other medical or psychological problems.
primary insomnia
In a person with insomnia, the worsened sleep problems that can occur when medications are used to treat insomnia and then withdrawn.
rebound insomnia
Sleep dysfunction involving an excessive amount of sleep that disrupts normal routines.
hypersomnolence disorders
Disorder involving brief periods when breathing ceases during sleep.
sleep apnea
Sleep disorder involving sudden and irresistible sleep attacks.
narcolepsy
Sleep disruption leading to excessive sleepiness or insomnia, caused by a breathing problem such as interrupted (sleep apnea) or labored (hypoventilation) breathing.
breathing-related sleep disorders
Sleep disturbances resulting in sleepiness or insomnia, caused by the body’s inability to synchronize its sleep patterns with the current pattern of day and night.
circadian rhythm sleep disorders
Frightening and anxiety-provoking dreams occurring during rapid eye movement sleep. The individual recalls the bad dreams and recovers alertness and orientation quickly.
nightmares
Category of sleep disorder during NREM sleep that includes sleepwalking and sleep terrors.
disorder of arousal
Episodes of apparent awakening from sleep, accompanied by signs of panic, followed by disorientation and amnesia for the incident. These occur during nonrapid eye movement sleep and so do not involve frightening dreams.
sleep terrors
Parasomnia that involves leaving the bed during nonrapid eye movement sleep. See also somnambulism.
sleepwalking (somnambulism)
Repeated sleepwalking that occurs during nonrapid eye movement sleep and so is not the acting out of a dream. The person is difficult to waken and does not recall the experience.
somnambulism
