|- Public Title||Treatment of obstructive sleep apnea and rehabilitation outcome in stroke.|
|- Scientific Title||Treatment of obstructive sleep apnea and rehabilitation outcome in stroke.|
|- hypothesis||In this study the relationship of OSAS with cognitive and functional status, and the effect of treatment with CPAP on outcomes of rehabilitation in stroke patients will be investigated.|
The main research questions are:
1. Is there a relationship between (the severity of) OSAS and cognitive and functional status?
2. Does CPAP treatment improve cognitive and functional outcome of rehabilitation?
Firstly, we expect to confirm that OSAS has an additional negative effect in stroke patients on cognitive and functional status. Secondly, we expect that CPAP treatment will improve outcomes of rehabilitation in stroke patients.

|- Brief summary||Several studies have shown a relationship between obstructive sleep apnea syndrome
(OSAS) and cardiovascular diseases, such as hypertension, heart disease and stroke. OSAS has also been associated with an increase of fatigue and depression, and a decrease of cognitive functioning.|
Stroke patients with OSAS have found to be more functionally impaired than stroke patients without OSAS. Moreover, OSAS seems to have an additional negative effect on existing cognitive deficits
due to the stroke. Continuous positive airway pressure (CPAP) is the most frequently used method of
treatment for OSAS. Although research on CPAP treatment in stroke patients is still scarce, treatment is found to improve rehabilitation outcome of stroke patients.
In this study the relationship of OSAS with cognitive and functional status, and the effect of treatment with CPAP on outcomes of rehabilitation in stroke patients will be investigated.
