A study led by Dr. Lena Lavie found that sleep apnea patients have increased adhesion molecules and free radicals on their white blood cells, which contribute to the development of atherosclerosis. Effective treatment with CPAP may not reverse this process, highlighting the need for further research.
Research found that people who habitually sleep more than 8 hours a night and those who need daytime naps have a 50% increased risk of dying, with nearly three times the risk from stroke. The study suggests an underlying sleep disorder may be to blame.
The study investigated LTF in OSA patients with hypoxic exposure using nasal CPAP. Hypoxia caused increased minute ventilation and decreased upper airway resistance, which persisted during the recovery period.
Researchers at UW-Madison found that female rats have an improved protective reaction to oxygen deprivation, suggesting a role for estrogen in respiratory control. The study suggests that gender hormones may be a factor in the development of obstructive sleep apnea, particularly in women.
A Mayo Clinic study found that patients with obstructive sleep apnea syndrome experienced a 24% rate of adverse postoperative outcomes compared to 9% without the condition. The study also revealed longer hospital stays and increased severity of upper airway obstructions in these patients.
Researchers found upper airway sensory impairment in snorers and OSA patients, increasing the risk of obstructive breathing episodes. The study also showed partial reversibility of sensory changes with continuous positive airway pressure treatment.
A pilot study found that an implanted 'brain pacemaker' for epilepsy may cause mild increases in sleep apnea, a condition where breathing is disrupted during sleep. Researchers are investigating ways to fine-tune the device to reduce these effects and improve treatment outcomes.
A new study by the University of Michigan found that a significant proportion of people with epilepsy may also have undiagnosed sleep apnea, which can disrupt brain function and exacerbate symptoms. The study suggests that addressing sleep apnea through lifestyle and medical interventions may help improve seizure control and quality of...
A five-year study found that people who snore are one and a half times more likely to have high blood pressure, with risk increasing with severity of sleep problem. The study suggests that physicians should consider hypertension when SDB is present.
A University of Michigan study suggests that patients with undiagnosed sleep apnea may not always describe their symptoms as 'sleepy', but rather experience fatigue, tiredness, or lack of energy. Laboratory sleep tests revealed interrupted breathing patterns in 73% of the study's subjects.
Scientists at the University of Illinois Chicago are exploring a novel approach to measuring sleepiness using pupil size, which could revolutionize the diagnosis of sleep disorders. The study aims to establish pupillometry as an objective measure of excessive daytime sleepiness and potentially improve treatment outcomes.
A study by American Academy of Neurology found that 80% of people with cluster headaches also have signs of obstructive sleep apnea, a condition that can trigger the attacks. Treatment of sleep apnea may reduce or eliminate headaches and other related problems.
Researchers developed a computer-controlled flow delivery device that monitors tracheal pressure and varies the flow of air to prevent apnea. The new technology may lead to alternative treatments for severely affected patients, potentially reducing the need for tracheotomies.
Researchers found that even mild to moderate sleep apnea significantly increases the risk of hypertension, with graver levels associated with higher likelihood. The study used data from the Wisconsin Sleep Cohort Study and found a substantial risk of hypertension in those with mild to moderate sleep apnea.
A study found that elderly COPD patients who use inhaled steroids can significantly reduce their rehospitalization and death risk. Additionally, postmenopausal women are more likely to develop sleep apnea and have a severe form of the condition. Meanwhile, researchers discovered age bias in lung cancer treatment, with older patients be...
A study of 290 pre- and 400 post-menopausal women found that sleep apnea is more prevalent and severe in the older group. The researchers suggest that lower levels of estrogen and progesterone during menopause may contribute to this disparity.
A large-scale NHLBI study found a significant relationship between sleep apnea and hypertension, with middle-aged adults at highest risk. The study revealed that even moderate levels of sleep apnea can increase the risk of hypertension in all participants, regardless of age or weight.
A study of 1050 men and 1098 women in Spain found that 26.2% of men and 28% of women experienced abnormal breathing during sleep, considered a threshold for obstructive sleep apnea (OSA). OSA is linked to increased risk of cardiovascular diseases and daytime drowsiness.
A new questionnaire effectively screens primary care patients for sleep apnea, identifying nearly half of high-risk patients. A man with severe adult-onset rheumatoid arthritis also experienced remission after a stem-cell transplant from his healthy twin, believed to be the first case of its kind.
Research found that young people under 45 with sleep apnea require aggressive treatment to reduce hypertension and cardiovascular issues. The study, published in the American Journal of Respiratory and Critical Care Medicine, included subjects aged 20-100 years old.
Researchers found a causal relationship between sleep-disordered breathing and hypertension in a substantial number of American adults. People with mild to moderate sleep apnea were 1.8 times more likely to have hypertension than those without, with the severity of apnea linked to increased blood pressure risk.
A study by UW Medical School reveals that women with sleep apnea exhibit similar symptoms as men, but are often misdiagnosed or overlooked. Health care providers may not be taking women seriously when they complain of daytime sleepiness and snoring.
