PAPER 2026 FULL SOLUTION SET
◉ What are Circadian rhythm sleep-wake disorders? Answer: These
are a group of sleep disorders characterized by disturbances in a
person's internal body clock.
◉ What is chronic insomnia? Answer: Sleep disturbances that occur
at least three nights a week for more than three months
◉ What is short-term insomnia? Answer: Difficulty falling asleep,
Difficulty staying asleep, Waking up early in the morning, and
Difficulty falling back asleep after waking up
◉ What are isolated symptoms and normal variants related to
insomnia? Answer: Refers to individual symptoms or variations in
sleep patterns that may not necessarily indicate a chronic or short-
term insomnia disorder
◉ What is obstructive sleep apnea disorder? Answer: A common
sleep disorder that causes the upper airway to repeatedly narrow or
close during sleep, leading to reduced or absent breathing. It can
occur in both children and adults.
,◉ What is central sleep apnea with Cheyne-Stokes breathing?
Answer: A breathing pattern characterized by alternating central
apneas and hyperpneas.
◉ sleep related breathing disorders (SRBD) Answer: central sleep
apnea-a sleep disorder that causes breathing to repeatedly stop and
start during sleep
◉ sleep related breathing disorders (SRBD) Answer: central sleep
apnea with Cheyene stokes breathing
◉ sleep related breathing disorders (SRBD) Answer: central sleep
apnea due to a medical disorder without Cheyne stokes breathing
◉ sleep related breathing disorders (SRBD) Answer: central sleep
apnea due to a medication or substance
◉ sleep related breathing disorders (SRBD) Answer: primary central
sleep apnea
◉ sleep related breathing disorders (SRBD) Answer: primary central
sleep apnea of infancy
, ◉ sleep related breathing disorders (SRBD) Answer: primary central
sleep apnea of prematurity
◉ sleep related hypoventilation disorders Answer: obesity
hypoventilation syndrome
◉ sleep related hypoventilation disorders Answer: congenital
central alveolar hypoventilation syndrome-a rare neurological
disorder that affects breathing, especially during sleep
◉ sleep related hypoventilation disorders Answer: idiopathic central
alveolar due to a med or substance-This rare disorder is
characterized by insufficient breathing during sleep
◉ sleep related hypoventilation disorders Answer: late onset central
hypoventilation with hypothalamic dysfunction-a rare life-
threatening condition characterized by the loss of automatic
breathing, more pronounced during sleep.
◉ sleep related hypoventilation disorders Answer: idiopathic central
alveolar hypoventilation due to med or substance-a rare life-
threatening condition characterized by the loss of automatic
breathing, more pronounced during sleep.
