Brief summary

The aim of the study is to evaluate brain perfusion on Tc-99m ECD SPECT/CT, cognition function test and questionnaires in OSA patients before and after treatment.

Interventions

There are two interventions (CPAP and surgery). CPAP: Brad of ResMed-- S8 autoset Spirit in automatic positive airway pressure model. The participants put on the facial mask when sleeping, open the power of machine and the machine will start to work and automatically give the postitive pressure. Duration: 4 to 8 hours a day for 3 months Surgery: Uvulopalatopharyngoplasty, occur once. Approximate duration of uvulopalatopharyngoplasty: 1 hour All participants undergo only one intervention.
