Clinical Trial Summary
Obstructive Sleep Apnea Syndrome (OSAS) is characterized by repeated episodes of airway
obstruction while sleeping. Upper airway obstruction while sleeping leads to a dramatic
decrease in oxygen saturation and to hypoxemia finally, in which consequence the patient
rapidly awake. Clinical signs are sleepiness and functional cognitive deficits. The Gold
standard therapy is "continuous positive airway pressure" ventilation during sleep. However,
the success depends strongly to the patient´s compliance. Surgical treatment is an
alternative option, which could be considered if clinical success failed. A comparison of the
cognitive function of both therapies is not yet analyzed. The study addresses the question
which of this treatment options is favorable regarding cognitive function and outcome.
Description:
Obstructive Sleep Apnea Syndrome (OSAS) is characterized by repeated episodes of airway
obstruction while sleeping. The "Apnea-hypopnea index" (AHI) defined as events per hour,
gives information about the severity of the disease. The American Academy of Sleep Medicine
Task Force" defined that more than 5 episodes per hour is strongly suspect for an OSAS
disease. Upper airway obstruction while sleeping leads to a dramatic decrease in oxygen
saturation and to hypoxemia finally, in which consequence the patient rapidly awake. The
prevalence rise with age and about 20% of the population is suspect to a sleep disorder.
However about 1-5% of male and about 0,5-2% of female aged adults are affected. Main reason
is obesity. Clinical signs are sleepiness and functional cognitive deficits. The Gold
standard therapy is "continuous positive airway pressure" ventilation during sleep. However,
the success depends strongly to the patient´s compliance. Surgical treatment is an
alternative option, which could be considered if clinical success failed. It is notable that
the long-term mortality is comparable in both medical treatment options. However, a
comparison of the cognitive function of both therapies is not yet analyzed. The study
addresses the question which of this treatment options is favorable regarding cognitive
function and outcome.
