Condition: OSA - Obstructive Sleep Apnea · Sponsor: IRCCS San Raffaele
Obstructive Sleep Apnea Syndrome (OSAS) is a sleep related breathing disorder with high epidemiological impact (9-38% of general population), more frequently reported in male gender and increasing with the age. Pathognomonic OSAS symptoms are snoring, excessive daytime sleepiness, sleep fragmentation, awakening during the night often for nocturia and morning headache. The repeated sleep fragmentation due to numerous awakenings (the patient is often unaware of this) can impair higher cognitive functions over the time and negatively impact the quality of life, If timely untreated. Among the most frequently impaired cognitive functions detected in OSAS patients, there are attention, concentration, amnestic and executive domains. While these impairments are well documented in literature, the pathogenetic mechanisms underlying cognitive impairment are not yet defined. To date, the most widely accepted pathophysiological hypotheses are two: i) intermittent hypoxia (frequent brain awakenings); ii) sleep fragmentation. Moreover solid evidence report that, there is a strict correlation between OSAS and neurodegenerative diseases, such as Mild Cognitive Impairment (MCI) and Alzheimer's Dementia (AD). Indeed, OSAS might act as a trigger, accelerating the accumulation of harmful proteins in the brain, in particular beta-amyloid and tau protein. The first-line treatment for OSAS is Continuous Positive Airway Pressure (CPAP). Of note is the effect of CPAP treatment on higher cognitive fu…
