Sickle cell disease (SCD) is an inherited blood disorder. Symptoms include acute and chronic complications. Due to progress in SCD care, patients with SCD are living longer than before and we focus more attention in chronic complications.
Children with SCD experience worse cognitive functions than healthy children, and fewer is known about cognitive functions in adults. Studies suggest lower cognitive performance in SCD, mostly in executive functions and processing speed, but the biological and anatomical substrates of cognitive decline are not yet well established in SCD. Often times, cognitive impairments and cerebral disorders are not diagnosed and treated in adults with SCD.
The main objective of this study is to propose a deep neuropsychological assessment in adults with SCD and cognitive complaints and to highlight links between cognitive functions and clinical, biological and neuroradiological markers. The hypothesis of this study is that cognitive functions are associated with severity of the SCD, with bood abnormalities, with MRI markers and Transcranial Doppler (TCD) markers of cerebrovascular disease. The secondary objective of this study is to validate a brief cognitive assessment tool (BEARNI tool) in adults with SCD.
This study is an observational cross-sectional study that will enroll adults with SCD and cognitive complaint.
