The hypothesis is that in sickle cell anaemia, nocturnal oxyhaemoglobin desaturation, is associated with low processing speed index, and this morbidity can be reduced with overnight auto Continuous Positive Airways Pressure and/or oxygen supplementation.

Device: auto Continuous Positive Airways Pressure (CPAP) with oxygen supplementation
