Cognitive Rehabilitation in Sickle Cell Disease
NCT01793740 · View on ClinicalTrials.gov ↗
Study Summary
The majority of school-age children with sickle cell disease (SCD) experience neurocognitive deficits, even in the absence of stroke. In particular, deficits in attention and working memory have emerged as two of the most common neurocognitive sequelae of SCD. Thus, the goal of the present proposal is to address feasibility and compliance of a novel computerized cognitive training program, Cogmed. Pilot data will also be collected to establish preliminary efficacy. Twenty-four children meeting initial age and diagnostic criteria will be identified and approached about participation by their attending physician during regularly-scheduled SCD clinic visits. Baseline assessments will include a brief measure of intellectual functioning, a brief cognitive testing battery evaluating processing speed and working memory, in addition to questionnaires regarding behavior and quality of life. Children will then be randomized to the computerized CT program Cogmed (n=12) or a waitlist control (n=12). Participants enrolled in the computerized CT program will be asked to complete 25-sessions of Cogmed over a five to eight week period (3 to 5 sessions per week). Following completion of the program, children and their parents will be asked to return to clinic for a follow-up visit. After a five to eight-week waiting period, children in the waitlist condition will also be asked to return to clinic for a second visit. Following this assessment, participants initially enrolled in the waitlist will be offered an opportunity to participant in the intervention. If interested, they will follow the same intervention protocol described above. These children will return to clinic for a third visit following completion of the intervention. Compliance rate and its confidence interval will be calculated for the overall study population. A t-test for binomial proportion with continuity correction will be used to examine whether the compliance rate is lower than the target. Participants' change in

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT01793740
The ClinicalTrials.gov registry entry for NCT01793740 describes a study currently listed as completed. It is categorized as NA, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 18 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Duke University, which has 1,129 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 2 conditions, with Sickle Cell Disease appearing as the primary indexed condition, and to 1 intervention — of which Cogmed is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT01793740 reports 1 study location spanning 1 distinct geographic area — top geographies include North Carolina. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
