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)
In Brief
A clinical study evaluating Effective CPAP and Sham CPAP for Memory Deficit. Completed, enrolled 40 participants across 1 site.
Detailed Summary
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".

Interventions
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
Similar CPAP machine delivering a 4 cm of water pressure that was too low to suppress sleep respiratory events.
