Neurological Deficits in Obstructive Sleep Apnea.

Neurological Deficits in Obstructive Sleep Apnea. Curr Treat Options Neurol. 2017 Apr;19(4):16 Authors: Ferini-Strambi L, Lombardi GE, Marelli S, Galbiati A Abstract OPINION STATEMENT: Obstructive sleep apnea (OSA) is the most common sleep-related breathing disorder characterized by repetitive episodes of complete or partial obstruction of the upper airway. The prevalence of this disorder is strictly dependent on its gravity. At ≥15 events/h apnea-hypopnea index (AHI), it ranges from 6 to 17% in the general population, with higher rates in men and increasing with age. The hypoxia induced by OSA severely affects the structure and function of blood vessels, culminating in mortality and morbidity. Its negative impact influences also cognitive functioning. Recent papers showed the relationship between OSA and some neurological disorders, such as neurodegenerative diseases, stroke, epilepsy, and headache. OSA may accelerate the onset of mild cognitive impairment and Alzheimer's disease (AD) and might also represent an independent risk factor for Parkinson's disease (PD). OSA is also frequent in multisystem atrophy. In the early stages of AD, continuous positive airway pressure (CPAP) treatment might slow down the progression of the disease, thus highlighting the potential importance of OSA screening and a timely intervention in these patients. Moreover, CPAP is effective in reducing daytime sleepiness in PD. OSA may induce seizures by m...
