The cap is then fitted with emitters and detectors to capture changes in cerebral hemodynamics in the frontal cortex.\n\nPrior to wearing the headband, participants will complete an assessment to estimate overall intellectual abilities based on their vocabulary skills (NIH Picture Vocabulary Test). Then the participants will complete four cognitive measures associated with frontal functioning while wearing the fNIRS headband. These tasks measure processing speed and working memory and take approximately 5-6 minutes each to complete.\n\nPhotobiomodulation using the CytonBrite PBM device will be performed immediately following the initial fNIRS exam. The CytonBrite headpiece will be placed on the head. The six LED probes will be positioned over the forehead, and the probes will be adjusted per device specifications to maximize light penetration to the prefrontal cortex. The patient will receive 10 minutes of continuous wave light or sham.\n\nFollowing stimulation or sham, the fNIRS cap will be placed in the same location and the same cognitive measures will be completed (4 measures of frontal functioning). Changes in cerebral hemodynamics and cognitive performance on four measures (2 working memory and 2 processing speed tasks) from pre- to post-stimulation will be compared between the two groups. This will take about 30 minutes.\n\nThe cap will be removed, and the caregiver and the participant will complete brief rating forms assessing perceived feasibility and acceptability of the intervention (FIM and AIM). Additionally, participants will be asked to report any side effects they experienced immediately following the intervention.\n\nAmong the participants that were randomized to TPBM, the sample (both caregiver and participant) will be further randomized to complete a brief (\\~10-15 minutes) interview assessing the perceived feasibility and acceptability of the TPBM intervention.\n\nApproximately one-week post-intervention, participants will complete the side effects questionnaires virtually.",[62,68,71,77],{"label":63,"type":64,"description":65,"interventionNames":66},"SCD Genotype SS\u002FSB0; Age 8-12 Years","ACTIVE_COMPARATOR","Transcranial photobiomodulation (TPBM), a light-based treatment using a fNIRS headset to capture changes in cerebral hemodynamics in the prefrontal cortex associated with (TPBM).",[67],"Device: Active Transcranial Photobiomodulation (TPBM)",{"label":69,"type":64,"description":65,"interventionNames":70},"SCD Genotype - SS\u002FSB0; Age 13-17 Years",[67],{"label":72,"type":73,"description":74,"interventionNames":75},"SCD Genotype - SC\u002FSB+; Age 8-12 Years","SHAM_COMPARATOR","Sham condition using a randomized block design involving 2 (TPBM): 1(sham) randomization.",[76],"Device: Sham Transcranial photobiomodulation (TPBM)",{"label":78,"type":73,"description":74,"interventionNames":79},"SCD Genotype - SC\u002FSB+; Age 13-17 Years",[76],[81,86],{"type":82,"name":83,"description":84,"armGroupLabels":85,"otherNames":49},"DEVICE","Active Transcranial Photobiomodulation (TPBM)","CytonBrite, 1064nm LED",[69,63],{"type":82,"name":87,"description":74,"armGroupLabels":88,"otherNames":49},"Sham Transcranial photobiomodulation (TPBM)",[78,72],[90],{"name":91,"affiliation":5,"role":92},"Andrew Heitzer, PhD","PRINCIPAL_INVESTIGATOR",[94],{"name":91,"role":95,"phone":96,"phoneExt":49,"email":97},"CONTACT","888-226-4343","referralinfo@stjude.org",{"type":99,"investigatorFullName":49,"investigatorTitle":49,"investigatorAffiliation":49,"oldNameTitle":49,"oldOrganization":49},"SPONSOR","100577383","transcranial-photobiomodulation-treatment-in-patients-with-sickle-cell-disease-100577383",false,"NCT06797583","Transcranial Photobiomodulation Treatment in Patients With Sickle Cell Disease","PHOTOSCAN","Inclusion Criteria:\n\n* Patient diagnosed with sickle cell disease of any genotype\n* Enrolled in the Sickle Cell Clinical Research and Intervention Program (SCCRIP)\n* Between the ages of 8 to 17 years\n* Primary language is English\n* Participant and Parent\u002FLegal Guardian is willing to participate and provide consent\u002Fassent according to institutional guidelines\n\nExclusion Criteria:\n\n* History of an abnormal transcranial doppler screening\n* History of a documented silent cerebral infarct\n* History of documented central nervous system injury, including a traumatic brain injury, Moya Moya disease, or overt stroke\n* Participant received transfusion treatment within the past three months.","ALL","8 Years","17 Years",{"count":111,"type":112},60,"ESTIMATED","INTERVENTIONAL",[115],"NA","Participants are being asked to take part in this clinical trial, a type of research study, because investigators want to learn more about oxygen usage in the brain.
