We assessed structural brain damage in obstructive sleep apnea syndrome OSA patients 21 males and the effects of long-term continuous positive airway pressure CPAP treatment 182 124 months. Sleep plays a vital role in maintaining longevity cardiovascular health memory consolidation and removal of poten- tially toxic metabolites from the brain Malhotra.

Brain Structure Network Analysis In Patients With Obstructive Sleep Apnea

The harmful effect of disturbed sleep on brain health is particularly important for older adults presenting obstructive sleep apnea OSA.

Brain structure and function obstructive sleep apnoea. Now there is also mounting research that the condition has negative impacts on brain structure and function. Obstructive sleep apnea has been connected to varying medical problems including high blood pressure heart disease and type II diabetes. Children with OSA presented abnormal neural activities in some brain regions and impaired cognitive functions with the former possibly being the neural mechanism of the latter.

Obstructive sleep apnoea OSA is associated with changes to the structure of the brain that are also seen in the early stages of dementia according to a study published in the European Respiratory Journal. People with obstructive sleep apnea often exhibit symptoms of impaired brain function including trouble concentrating or recalling things and reduced cognition as well as fluctuating moods increased stress irritability depression and anxiety. Obstructive sleep apnea OSA is a common sleep disorder affecting at least 2 to 4 of middle-aged individuals.

This paper summarizes a review of articles that have explored the relationship between obstructive sleep apnea OSA brain infractions and cognitive dysfunction. Knowledge of the brain structures involved in OSA and the corresponding functional implications could provide clues to the pathogenesis of cognitive impairment and its reversibility in this disorder. OSA is associated with neurocognitive and cardiovascular morbidities1 reduced quality of life2 impaired work-performance and increased risk of.

Department of Bioengineering University of Texas at Arlington Arlington TX USA. Obstructive sleep apnea OSA is commonly associated with neurocognitive impairments that have not been consistently related to specific brain structure abnormalities. Background Obstructive sleep apnoea OSA is a common disease that leads to daytime sleepiness and cognitive impairment.

Biosense Webster New York NY USA. 4 Introduction Obstructive Sleep Apnea OSA is a common sleep-disorder affecting at least two to four percent of middle-aged individuals. 8-44 months on brain structures and investigated the relationship between severity of OSA and effects of treatment.

The researchers worked with a group of 83 people aged between 51 and 88 years who had visited their doctor with concerns over their memory or mood but had no OSA diagnosis. The articles were selected based on a systematic search on PubMed and Medline databases using the key words sleep apnea OSA hypoxia sleep fragmentation cerebral hemodynamics metabolism brain structure cognition memory quality of life neuropsychological deficits and CPAP treatment The review suggests that OSA-mediated brain hemodynamics and brain atrophy are concomitant with. Using deformation-based morphometry to measure local volume changes we.

Attempts to investigate changes in brain morphology that may underlie these impairments have led to conflicting conclusions. With increasing age there are substantial differences in OSAs prevalence associated comorbidities and phenotypic presentation. Treatment Obstructive sleep apnea OSA is a common sleep disorder affecting at least 2 to 4 of middle-aged.

OSA causes not only sleep fragmentation but also intermittent hypoxia which may affect both brain structure and function. Treatment Page 4 of 55. Brain hemodynamics structure and function.

The effectiveness of continuous positive airway pressure CPAP treatment on the reversibility of structural and. The anomalies in brain hemodynami. It has also been shown to put people at greater risk for heart attacks and stroke.

Obstructive sleep apnea OSA is commonly associated with neurocognitive impairments that have not been consistently related to specific brain structure abnormalities. OSA is common particularly after the age of 65 years when it has an estimated prevalence of at least 20. Increasing evidence links cognitive-decline and Alzheimers disease AD to various sleep disorders including obstructive sleep apnea OSA.

OSA is associated with neurocognitive and cardiovascular morbidities 1 reduced quality of life 2 impaired work performance and increased risk of vehicular and industrial accidents 3.

The anomalies in brain hemodynamics brain atrophy and cognitive dysfunction resulting from OSA are reviewed. Obstructive sleep apnea children resting-state fMRI cognitive function. Using functional magnetic resonance imaging fMRI approaches deficits in working memory tasks in adults with sleep apnoea have been correlated with decreased activation of brain regions associated with such tasks such as the frontal lobes Thomas et al2005.
