Links Between Cognitive Functions and Clinical, Biological and Neuroradiological Outcomes in Adults With Sickle Cell Disease.

Plain-language summary
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.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
