Epidemiology of sleep disturbances and vascular consequences

Obstructive sleep apnea

Obstructive sleep apnea (OSA) can be defined as a transient cessation in breathing (apnea) or a reduction in breathing amplitude (hypopnea) as a result of collapsed or obstructed upper airway; both can cause notable arterial hypoxemia and hypercapnia. The apnea/hypoapnea index (AHI) categorizes OSA patients into three groups: mild (5-15), moderate (15-30) and severe (>30) whereas the number indicates the total number of apnea/hypoapnea episodes per hour of sleep {Badran et al., 2014, #73409}. Although many sleep clinics adopted this diagnostic tool, diagnostic variability remains {Caples et al., 2005, #48595}. AHI measures the frequency of disordered breathing events but does not quantify other processes involved in the pathophysiology of OSA, such as the degree of oxygen desaturation. For instance, the increasing length of apnea/hypoapnea events will likely increase oxygen desaturation events which is very stressful and have more severe pathological impact than shorter ones. Paradoxically, lengthening of apnea/hypoapnea events can lead to a decrease in AHI {Kulkas et al., 2013, #24356}. …show more content…

According to the Adult Obstructive Sleep Apnea Task Force of the American Academy of Sleep Medicine. High-risk patients with nocturnal symptoms of OSA should undergo sleep testing, including obese, hypertensive, systolic or diastolic heart failure, congestive heart failure, coronary artery disease, stroke or transient ischemic attack and tachy or bradyarrhythmias. Full-night PSG is recommended for the diagnosis of sleep related breathing disorders but a split-night study could be an alternative {Epstein et al., 2009,

  • Sleep Physiology And Chronobiology Essay

    1611 Words  | 4 Pages

    We live our entire life in two states, sleep and awake1. These two states are characterized by two distinct behaviors. For instance, the brain demonstrates a well-defined activity during non-REM sleep (nREM) that is different when we are awake. In the study of sleep by Huber et. al., the authors stated that sleep is in fact a global state2. It is unclear whether this statement means that sleep is a state of global behavioural inactivity or the state of the global nervous system. The notion that sleep is a global state of the nervous system served as basis for sleep researchers to search for a sleep switch. The discovery of the sleep switch, in return, provided evidence and enhanced the notion that sleep is a global state of the nervous system. The switch hypothesis developed from the fact that sleep can be initiated without fatigue and it is reversible1. It was hypothesized that there is something in the brain that has the ability to control the whole brain and initiate sleep. Studies have found a good candidate that demonstrated this ability3. They found a group of neurons in the Ventrolateral Preoptic (VLPO) nucleus. It was a good candidate because it was active during sleep, has neuronal output that can influence the wakefulness pathway, and lesion in the area followed reduce sleep3. The idea that there is something that can control the whole brain and result sleep state supports the idea that sleep is a global state of the nervous system.

    There is no consensus regarding the mechanism of manifestation of neurocognitive consequences associated with obstructive sleep apnea (OSA) and their definite underlying process is unknown. However, there are some findings and theories about it. In OSA, there are different levels of hypoxia which are associated with many factors such as obesity and etc.1 The hippocampus has a region (CA1) which is more vulnerable and sensitive to the hypoxia that leads to inflammatory response (COX-2, TNF-a),2 which can bring about endothelial dysfunctions,3 disturbances of cerebrovascular blood flow,3 and consequently neuronal cells death.3 In addition, it provokes oxidative stress and nitric oxide synthase (iNOS).2 Another finding is related to NDPH (subtype

  • Essay On Sleep Cycle

    The test results were normal and the recorded long periods of silence and every now and then movement, a cough, maybe a little snore but that was all. At any rate, stage 2 (NREM-2) of the sleep cycle produces what is known as sleep spindles or bursts of rapid, rhythmic brain-wave activity which lasts about twenty minutes. As your heart rate begins to slow down and your body temperature drops you transition into a deeper sleep and this is stage 3 (NREM-3) of the sleep cycle. Slower brain waves or delta waves occur and a person becomes less responsive to any activity around them, such as noise. The person becomes like that of a dead person or at least that is what my Uncle Herbert would say. He told me I sleep like I am dead. He said he pinched me and hollered at me and I still would not wake up.
