BACKGROUND: Association between cerebral infarction site and poststroke sleep-disordered breathing (SDB) has important implications for SDB screening and the pathophysiology of poststroke SDB. Within a large, population-based study, we assessed whether brainstem infarction location is associated with SDB presence and severity. METHODS: Cross-sectional study was conducted on ischemic stroke patients in the Brain Attack Surveillance in Corpus Christi (BASIC) project...

PURPOSE OF REVIEW: An understanding of the impact of sleep on neurologic disorders, and the impact of neurologic disorders on sleep, provides fresh opportunities for neurologists to improve the quality of life and functioning of their patients. RECENT FINDINGS: Sleep-disordered breathing (SDB) is a risk factor for cerebrovascular disease and should be considered in all TIA and stroke patients. Sleep disorders can amplify nociception and worsen headache disorders; and some headaches, including those related to SDB and hypnic headache, are sleep specific...

Breathing is a primal homeostatic neural process, regulating levels of oxygen and carbon dioxide in blood and tissues, which are crucial for life. Rhythmic respiratory movements must occur continuously throughout life and originate from neural activity generated by specially organized macro- and microcircuits in the brainstem. In the respiratory network there is a spatial and dynamic hierarchy of interacting circuits, each of which controls different aspects of respiratory rhythm generation and pattern formation, which can be revealed as the network is progressively reduced...

BACKGROUND: Control of ventilation depends on a brainstem neuronal network that controls activity of the motor neurons innervating the respiratory muscles. This network includes the pontine respiratory group and the dorsal and ventral respiratory groups in the medulla. Neurologic disorders affecting these areas or the respiratory motor unit may lead to abnormal breathing. REVIEW SUMMARY: The brainstem respiratory network contains neurons critical for respiratory rhythmogenesis; this network receives inputs from peripheral and central chemoreceptors sensitive to levels of carbon dioxide (PaCO2) and oxygen (PaO2) and from forebrain structures that control respiration as part of integrated behaviors such as speech or exercise...

OBJECTIVE: To investigate nocturnal sleep breathing disturbance in patients with ischemic cerebral stroke. METHODS: Forty-one patients with cerebral infarction undertook all-night screening of sleep breathing. The clinical features between cerebral infarction concomitant with mild and severe sleep breathing disturbance were compared, and the effects of different infarcted sites and sizes, the infarction history and symptoms on the breathing disorders were analyzed...

Central sleep apnoea (CSA) is a breathing disorder characterized by repetitive central apnoeas with hypoxia interrupted by hyperventilation phases. In the literature, there are reports of CSA caused by brainstem infarcts. We report two patients (38 and 53 years old) with longstanding history of central sleep apnoea who died during sleep. In both cases the autopsy revealed acute bilateral hypoxic lesions at the level of the solitary tract nuclei. In one case, symmetrical selective neuronal necrosis was found in the dorsal part of the solitary tract nuclei...

More than 50% of stroke patients have sleep-disordered breathing (SDB), mostly in the form of obstructive sleep apnea (OSA). SDB represents both a risk factor and a consequence of stroke. The presence of SDB has been linked with poorer long-term outcome and increased long-term stroke mortality. Continuous positive airway presure is the treatment of choice for OSA. Oxygen and other forms of ventilation may be helpful in other (e.g., central) forms of SDB. SDB can improve spontaneously after stroke. About 20 to 40% of stroke patients have sleep-wake disorders (SWD), mostly in form of insomnia, excessive daytime sleepiness/fatigue, or hypersomnia (increased sleep needs)...

Control of ventilation depends on a brainstem neuronal network that controls activity of the motor neurons innervating the respiratory muscles. This network includes the pontine respiratory group and the dorsal and ventral respiratory groups in the medulla, which contain neurons that fire primarily during inspiration, post-inspiration, or expiration. The ventral respiratory group includes the pre-Bötzinger complex, which contains neurokinin-1 receptor immunoreactive neurons critical for respiratory rhythmogenesis...

Four basic control mechanisms of breathing (brainstem respiratory centre, peripheral and central chemoreceptors, intero- and exteroceptive reflexes and suprapontine influences), as well as their sleep-related disorders are analysed. A decrease in central chemoreceptor sensitivity to CO2 and an increase in upper airway resistance during sleep result in hypoventilation and mild hypoxaemia already in physiological conditions. Compensatory increase in ventilatory effort with synchronous inhibition of pharyngeal dilators during sleep reduces the upper airway lumen manifesting with snoring, upper airway resistance syndrome, and OSA...

Respiratory function depends on numerous neurologic structures, the organization of which extends from the cerebral cortex to the medulla. The study of patients who have had strokes has allowed deductions about this organization, and various neurologic pathways have been increasingly recognized. The voluntary pathway travels with the corticospinal motor tract. It is typically damaged in the "locked-in" syndrome and leads to normal automatic breathing that cannot be voluntarily altered. The automatic pathway takes its origin in the lower brainstem and is damaged mainly in lateral medullary strokes...

Sleep pattern and breathing in humans are altered following cerebrovascular accidents involving the brainstem. Sleep apnea is a well-established complication of stroke involving the brainstem. On the other hand, the effect of cerebral stroke on sleep and breathing has not been well defined. The diffuse cerebral symptoms such as cognitive deficits, depression or fatigue, after hemispheric stroke mimic those present in patients with sleep apnea. To define the breathing pattern in patients with stroke involving cerebral hemispheres without brainstem lesion and without the prior history of sleep-disordered breathing, we studied 10 patients within 1 year of their stroke...

Medullary disorders can be associated with a sleep apnea syndrome. The present patient developed a sleep apnea syndrome with approximately 25 episodes of apnea or hypopnea during each hour of sleep following a lateral medullary infarction. The presence of predisposing factors and involvement of respiratory centers in the area of the medullary lesion may determine the appearance of sleep apnea with brainstem infarction. Investigation of breathing during sleep may be helpful in such cases.
