Pediatric breath-holding episodes, also called apnea, are a phenomenon in which children suddenly appear to stop crying and breathing when they are crying vigorously. If this happens occasionally, it usually does not affect the child’s health very much and there is no need to worry about it. However, if the breath-holding attack is prolonged, it may lead to hypercapnia and hypoxia of the pediatric brain; due to the contraction of the cerebral blood vessels and the secondary spasm of the respiratory tract during crying, it may also cause syncope and convulsions in the end. This disease is most often seen in infants and toddlers, most often in children between two and three years old; before 6 months of age and rarely after 6 years of age, it is best to remove the triggers and not to let the child cry or be afraid, which is the main means of prevention.
