Neurocognitive and behavioral consequences
Nocturnal sleep fragmentation has been linked to neurocognitive impairments, therefore, the identification of SDB such as OSA is crucial in children, those impairments having the possibility to be reversible with the appropriate treatment for the sleep disorder. The neurocognitive and behavioral dysfunctions commonly present in children with OSA include the following: hyperactivity, impulsivity, aggressive behaviors, low social and communication abilities and reduced adaptive skills. Children with OSA commonly show cognitive deficits, resulting in attention and concentration difficulties, as well as lower academic performance and IQ. Poor academic performances have been linked to OSA and suggested to result from cortical and sympathetic arousals and hypoxemia which affects memory consolidation. A study with Indian children affected by OSA has shown poor school grades, including mathematics, science, language and physical education. This study allowed to see the overall impact of OSA on learning abilities associated with language or numeracy skills, and physical development. It has been suggested that the deficits in academic performance related to OSA could be mediated through reduced executive functions or language skills, those domains contributing highly to learning abilities and behavior. The deficits in school performance can nevertheless be improved if adenotonsillectomy is performed on children to treat the OSA. It is thus crucial to identify the OSA for children with school difficulties; many cases remaining unnoticed.As studies have shown that learning skills and behaviors can be improved if the OSA is treated, the neurocognitive and behavioral deficits are thus at least partly reversible.
They found that OSA can cause problems in mentally manipulating non-verbal information, in executive functions and working memory. This repeated brain hypoxia is also considered to be a cause of Alzheimers disease.Diagnosis of obstructive sleep apnea is significantly more common among people in relationships, who are alerted to their condition by being informed by their sleeping partner since individuals with obstructive sleep apnea are often unaware of the condition. There is a stigma associated with loud snoring, and it is not considered a feminine trait. Consequently, females are less likely to be told by their partners that they snore, or to admit it to themselves or doctors. Furthermore, CPAP (Continuous Positive Airway Pressure) machines are also perceived negatively by females, and less likely to be utilized to their full extent in this group. Children
Although this so-called "hypersomnolence" (excessive sleepiness) may also occur in children, it is not at all typical of young children with sleep apnea. Toddlers and young children with severe OSA instead ordinarily behave as if "over-tired" or "hyperactive"; and usually appear to have behavioral problems like irritability, and a deficit in attention. Adults and children with very severe OSA also differ in typical body habitus. Adults are generally heavy, with particularly short and heavy necks. Young children, on the other hand, are generally not only thin but may have "failure to thrive", where growth is reduced.
