“…By analyzing the OSA cases separately we found that only seven of them do not demonstrate memory fixation deficits. This tendency corresponds to the one described by Borak et al and Lee et al who observe identical correlation among OSA patients in their study ( 26 , 27 ).…”

Cognitive Impairment and Affective Disorders in Patients With Obstructive Sleep Apnea Syndrome

et al. 2018

Sleep-related breathing disorders could be accompanied by or caused by a variety of medical conditions. They are considered to be a significant medical and social problem. Together with excessive daytime sleepiness, patients with obstructive sleep apnea experience neuropsychological symptoms such as anxiety, attention deficits, cognitive impairment, depressive symptoms and other psychological disturbances leading to social adjustment difficulties. Patients diagnosed with obstructive sleep apnea demonstrate a decline in a wide spectrum of cognitive abilities, including memory, attention, psychomotor speed, executive, verbal and visual-spatial skills. The aim of this study is to investigate the cognitive functioning and affective disorders among patients with obstructive sleep apnea syndrome and to examine the frequency and severity of cases in comparison with a control group consisting of healthy volunteers. Our research has shown that there is a relation between sleep apnea and cognitive impairments and affective changes. This relation can be explained by the direct effect of the syndrome on the patient, where the main connecting factor is the severity and the distribution of excessive daytime sleepiness. Along with treatment of the somatic medical condition, it is extremely important that the patient's mental state is treated as well.Trial Registration: 57/2013, Medical University - Sofia, Bulgaria.

“…It has been found that severe OSAS patients' performance was poor in short-term verbal memory tests [53, 87], long-term learning, and memory tests [53] as well as working [88], visual and spatial memory tests [60, 87]. …”

“…OSAS patients have repeatedly been presented with serious impairments in memory and learning abilities [ 82 ], such as episodic memory [ 84 ], short-term memory [ 69 ], long-term verbal memory [ 84 ], and verbal and visual learning abilities [ 86 ]. It has been found that severe OSAS patients' performance was poor in short-term verbal memory tests [ 53 , 87 ], long-term learning, and memory tests [ 53 ] as well as working [ 88 ], visual and spatial memory tests [ 60 , 87 ].…”

“…Although the bulk of the research conducted on the impact of OSAS on neurocognitive functions focuses on cognitive functions such as attention, memory, and executive functioning rather than on language abilities, there have been some studies on OSAS patients that have shown significant semantic language deficits on their part [ 73 , 87 ], although this has not always been the case [ 94 ]. The fact that more research has been carried out on cognitive abilities other than language is probably associated with the fact that some of them, for example, attention and memory problems, are more easily noticed by patients themselves as well as by their bed partners and doctors than language deficits are.…”

“…However, the mechanism of cognitive deficits in OSAS is still unclear and the results of the researches are complicated and equivocal. For example, there are studies that link hypoxemia with attention [ 112 ] and delayed recall [ 85 ] and on the other hand, sleep architecture is related to language and executive functioning [ 87 ]. Other researches failed to associate executive functions, such as working memory, with hypoxemia [ 83 ].…”

Effects of Chronic Obstructive Pulmonary Disease and Obstructive Sleep Apnea on Cognitive Functions: Evidence for a Common Nature

2014

View full text Add to dashboard Cite

Patients with chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea syndrome (OSAS) show similar neurocognitive impairments. Effects are more apparent in severe cases, whereas in moderate and mild cases the effects are equivocal. The exact mechanism that causes cognitive dysfunctions in both diseases is still unknown and only suggestions have been made for each disease separately. The primary objective of this review is to present COPD and OSAS impact on cognitive functions. Secondly, it aims to examine the potential mechanisms by which COPD and OSAS can be linked and provide evidence for a common nature that affects cognitive functions in both diseases. Patients with COPD and OSAS compared to normal distribution show significant deficits in the cognitive abilities of attention, psychomotor speed, memory and learning, visuospatial and constructional abilities, executive skills, and language. The severity of these deficits in OSAS seems to correlate with the physiological events such as sleep defragmentation, apnea/hypopnea index, and hypoxemia, whereas cognitive impairments in COPD are associated with hypoventilation, hypoxemia, and hypercapnia. These factors as well as vascocerebral diseases and changes in systemic hemodynamic seem to act in an intermingling and synergistic way on the cause of cognitive dysfunctions in both diseases. However, low blood oxygen pressure seems to be the dominant factor that contributes to the presence of cognitive deficits in both COPD and OSAS.
