Breath-holding spells occur in approximately 5% of the population with equal distribution between males and females. They are most common in children between 6 and 18 months and usually not present after 5 years of age. They are unusual before 6 months of age. A positive family history can be elicited in 25% of cases.
Obstructive sleep apnea is the most common Sleep-Disordered Breathing (SDB) and affects up to 11% of children born at term – it is even more common (3 to 6 times more) in children born pre-term. [67]
Sleep apnea is a common sleep disorder that affects more than 20 percent of people in the United States. It happens when your breathing temporarily stops while you sleep. Depending on the severity ...
Sleep apnea may be categorized as obstructive sleep apnea (OSA), in which breathing is interrupted by a blockage of air flow, central sleep apnea (CSA), in which regular unconscious breath simply stops, or a combination of the two. [1] OSA is the most common form. [1]
The respiratory disturbance index (RDI)—or respiratory distress Index—is a formula used in reporting polysomnography (sleep study) findings. Like the apnea-hypopnea index (AHI), it reports on respiratory distress events during sleep, but unlike the AHI, it also includes respiratory-effort related arousals (RERAs). [1]

The Apnea–Hypopnea Index or Apnoea–Hypopnoea Index (AHI) is an index used to indicate the severity of sleep apnea. It is represented by the number of apnea and hypopnea events per hour of sleep. Apnea is the complete absence of airflow through your nose and mouth. Hypopnea is a partial collapse of your airway, limiting breathing.
Symptoms of infantile apnea occur most frequently during the rapid eye movement (REM) stage of sleep. [4] The nature and severity of breathing problems in patients can be detected in a sleep study called a polysomnography which measures the brain waves, heartbeat, body movements and breathing of a patient overnight.
