Summary
Obstructive sleep apnea syndrome (OSAS) impairs cognitive functions like memory and attention. Early treatment with CPAP may reverse brain changes, underscoring the need for timely OSAS diagnosis and management.
Area of Science:
- Neurology
- Sleep Medicine
- Cognitive Science
Background:
- Obstructive sleep apnea syndrome (OSAS) is a prevalent condition with significant health consequences.
- OSAS adversely affects neurocognitive functions, including reasoning, attention, learning, and memory.
- In children, OSAS is linked to attention-deficit hyperactivity disorder, behavioral issues, and learning disabilities.
Purpose of the Study:
- To review the impact of OSAS on neurocognitive functioning.
- To identify risk factors and underlying mechanisms of cognitive impairment in OSAS.
- To explore neuroimaging findings and treatment implications for OSAS-related cognitive dysfunction.
Main Methods:
- Review of existing studies on OSAS and neurocognitive impairment.
- Objective measurement of cognitive deficits using standardized tests (e.g., WAIS-R, PVT).
- Analysis of neuroimaging studies (fMRI, structural MRI) to identify affected brain regions.
Main Results:
- OSAS negatively impacts various cognitive domains and is associated with specific risk factors.
- Cellular mechanisms include intermittent hypoxia, hormonal imbalance, inflammation, and endothelial dysfunction.
- Neuroimaging reveals decreased hippocampal volume and gray matter reductions in frontal and parietal lobes.
Conclusions:
- Cognitive impairment is a significant consequence of OSAS, affecting multiple brain areas.
- Treatment with CPAP may partially reverse structural brain changes associated with OSAS.
- Further research is essential due to limitations in current data, emphasizing early OSAS recognition and treatment.

01:21Sleep Apnea
Sleep apnea is a condition where breathing stops intermittently during sleep, often leading to significant health issues. Each episode can last from 10 to 20 seconds or more and is frequently accompanied by a brief arousal from sleep. This disturbance, largely unnoticed by the individual, can lead to severe daytime fatigue. Commonly, individuals seek help after being informed by their partners about loud snoring and noticeable breathing pauses during sleep.

01:24Sleep-Wake Cycles
Sleep is an essential physiological process vital to maintaining overall well-being. The reticular activating system (RAS), a network of neurons in the brainstem, regulates wakefulness and sleep. While it may seem passive, sleep consists of distinct cycles, each with its unique characteristics and functions. Two key sleep phases are non-rapid eye movement (NREM) and rapid eye movement (REM).
NREM Sleep
NREM sleep comprises four progressive stages that seamlessly merge:

01:13Insufficient Sleep and Sleep Deprivation
Insufficient sleep refers to not getting the recommended amount of sleep for optimal functioning, even if it's just slightly less than needed. Sleep insufficiency may occur due to lifestyle choices, such as staying up late for social events or work, resulting in routinely getting less sleep than required. For example, consistently sleeping 6 hours when the body needs 7-9 hours can lead to cumulative effects on health and well-being.

01:07Narcolepsy
Narcolepsy is a chronic sleep disorder characterized by pervasive, uncontrolled sleepiness and other sleep disturbances. One of its hallmark symptoms is an abrupt transition to REM sleep upon falling asleep, which causes symptoms typically associated with this phase to occur unexpectedly during wakefulness. These include the following symptoms, which typically last from a minute or two to half an hour.
01:15REM Sleep Behavior Disorder
REM Sleep Behavior Disorder (RBD) is a sleep disorder characterized by the absence of muscle paralysis that normally occurs during the REM phase of sleep. This absence allows individuals to physically act out their dreams, which are often vivid and disturbing. Common behaviors exhibited during episodes include kicking, punching, and yelling. These actions can be dangerous, potentially leading to injuries for the person with RBD or their bed partner.

01:29Alzheimer Disease l: Introduction
Alzheimer disease is a chronic, progressive, and irreversible neurodegenerative disorder and the most common cause of dementia in older adults. It leads to gradual neuronal loss, causing cognitive decline, behavioral changes, and loss of functional independence.Risk Factors and EtiologyThe disease is multifactorial. Age is the strongest risk factor, with prevalence doubling every 5 years after age 65. Genetic factors include mutations in genes such as APP, PSEN1, and PSEN2, which are associated...
