Protocol Memory Deficit in Patients With Obstructive Sleep Apnea Syndrome
Comparison of the Evolution of Memory Deficit in Patients With Sleep Apnea Obstructive Syndrome (SAOS) Before and After "Effective" Versus Sham Treatment by Positive Pression Continues (PPC)
The main objective of this study is to evaluate the evolution of memory deficit (verbal episodic memory, procedural memory, working memory, short-term memory) in Sleep Apnea Obstructive Syndrome (SAOS) patients after treatment by Continuous Positive Airway Pressure treatment (CPAP). For thus, we will compare memory tests in two separate groups of SAOS patients with "effective " versus "ineffective" ( or sham) CPAP, before and 6 weeks after the beginning of the treatment. Thus we will assess the evolution of memory deficit, the effectiveness of the treatment on the evolution of memory deficit before and 6 weeks after the beginning of the treatment by "effective " versus "ineffective" CPAP.
We feel the results of the tests of memory will show greater memory disorders in patients with SAOS before beginning the treatment rather than six weeks afterwards. Thus we hypothesise that, after the treatment by "effective" CPAP, the patients with SAOS will have greater improvement of their memory disorders than those treated by "sham CPAP".

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Effective CPAP treatment
Effective Continuous Positive Airway Pressure treatment (CPAP) applied for 6 weeks
|
Auto-titrating CPAP machines (Remstar Auto; Philips Respironics, Murrysville, PA) provided by a home care company (Bastide Medical, France).
Pressure was set between 6 and 14 cm of water
|
Sham Comparator: Sham CPAP treatment
Ineffective Continuous Positive Airway Pressure treatment (sham CPAP) applied for 6 weeks
|
Similar CPAP machine delivering a 4 cm of water pressure that was too low to suppress sleep respiratory events.
