Obstructive Sleep Apnea Syndrome (OSAS) is characterized by repeated episodes of upper airway obstruction during sleep that result in intermittent hypoxemia and arousal. The prevalence of OSAS increases with aging, occurring in up to 25% of older adults and up to 48% in patients with Alzheimer's disease. OSAS causes hypoxia, fragmented sleep, daytime sleepiness, cognitive dysfunction, functional decline, and brain damage resulting from reduced cerebral blood flow, ischemic brain lesions… 
Can sleep apnea cause Alzheimer's disease?
Sleep in Neurodegenerative Disorders
RBD can precede PD motor symptoms by several years, and it represents a window of opportunity to treat the disease process when a disease-modifying therapy for PD becomes available in the future.

The Syndrome of Sleep Apnea in the Elderly Suffering from COPD and Live in the County of Attica, Greece
Investigation among a large group of elderly people living in the Attica Basin found that 98.0% of the participants have abnormal sleepiness during the day, and emphasis should be given on early diagnosis and treatment of sleep apnea syndrome, in order to improve the quality of the elderly life.
“ Τ he Syndrome of Sleep Apnea in the elderly suffering from COPD and live in the county of Attica ”
The purpose of this study is the identification of the problem among the elderly people living in the region of chronic obstructive pulmonary disease and obstructive sleep apnea syndrome.
[Sleep and cognitive impairment in neurodegenerative diseases].
The relationship between sleep and wakefulness disorders and cognitive impairment as well as clinical forms of sleep and waking disorders and treatment methods in patients with Parkinson's disease, Lewy body dementia and Alzheimer's disease are discussed.
Does Sleep Differ Among Patients with Common Musculoskeletal Pain Disorders?
A critical overview of the current understanding of pain and sleep interaction is provided, discussing evidence-based and empiric knowledge that should be considered in further research and clinical applications.
Sleep and Cognitive Impairments in Neurodegenerative Diseases
This article presents a detailed analysis of the literature linking sleep and waking impairments and cognitive impairments in neurodegenerative diseases and the phenomenology and methods of correcting sleep and wakes impairment in these diseases are discussed.
Sleep Disorders Associated With Movement Disorders and Dementia
The neuroanatomical basis of sleep, the associated regulatory mechanisms and neurotransmitters, and the relationship between cognitive function and sleep are addressed and the clinical features of sleep disorders in a wide variety of neurodegenerative diseases are reviewed.


Relationship between inflammation and cognitive function in obstructive sleep apnea
TNF-R1 as a marker of chronic inflammation may be associated with diminished neuropsychological functioning in patients with OSA and this study examined the effect of inflammatory parameters on cognitive dysfunction.

Dementia in Institutionalized Elderly: Relation to Sleep Apnea
The hypothesis for study is that sleep apnea causes deficits in brain function, possibly due to global effects rather than any particular cortical or subcortical structure, and there is a strong relationship between dementia andsleep apnea when theSleep apnea and dementia are severe.
Cognitive impairment in patients with obstructive sleep apnea and associated hypoxemia.
It is concluded that patients who have sleep apnea with associated hypoxemia have cognitive impairment which is more severe than those withSleep apnea without Hypoxemia.
Treatment with Continuous Positive Airway Pressure Is Not Effective in Patients with Sleep Apnea but No Daytime Sleepiness
The available evidence supports the notion that CPAP is an effective symptomatic treatment for patients with the sleep apneahypopnea syndrome, and a multicenter randomized, placebo-controlled, parallel-group study was designed to evaluate the short-term effects of CPAP on quality of life, objective sleepiness, cognitive function, and arterial blood pressure in nonsleepy patients with a pathologic apnehypopna index.
Cognitive function and sleep related breathing disorders in a healthy elderly population: the SYNAPSE study.
The impact of undiagnosed SRBD on cognitive function appeared quite limited in a generally older healthy population, and only slightly affected severe cases.
Positron emission tomography findings in obstructive sleep apnea patients with residual sleepiness treated with continuous positive airway pressure.
The frontal abnormality seems to distinguish the OSAS patients with UPS from the whole OSAS population, examined in previous studies, and positron emission tomography scanning with the tracer fluorine-18 fluorodeoxyglucose (FDG) was performed in 7 of the UPS patients.
