CPAP therapy provides a memory boost for adults with sleep apnea

July, 2010

Patients with obstructive sleep apnea treated with CPAP therapy not only outperformed untreated OSA patients on a memory task, but they outperformed those without OSA.

A study involving 135 adults (33-65) has found that, not only did patients with obstructive sleep apnea who were being treated with CPAP therapy outperform untreated OSA patients on an overnight picture memory task, but they outperformed controls who did not have OSA. The memory task involved being shown 20 photographs before spending the night in the sleep lab, and then having to choose the familiar photo from 20 similar pairs in the morning. CPAP therapy provides a steady stream of air through a mask that is worn during sleep.

Sleep apnea in children and teens linked to lower academic grades

July, 2010

A study of overweight children and adolescents has found that moderate to severe obstructive sleep apnea was linked to both lower academic grades and behavioral concerns.

A study involving 163 overweight children and adolescents aged 10 to 17 has revealed that moderate to severe obstructive sleep apnea was linked to both lower academic grades and behavioral concerns. None of the students with moderate to severe OSA had an "A" average, and 30% had a "C" average or lower. In contrast, roughly 15% of those without sleep-disordered breathing had an "A" average, and only about 15% had a "C" average or lower. The results remained significant after adjustment for sex, race, socioeconomic status and sleep duration on school nights. OSA was particularly associated with inattention and poor study skills in real-world situations Forty-two students had moderate to severe OSA; 58 had mild OSA; 26 students were snorers; 37 had no sleep-disordered breathing.
