Working Memory Performance Among Childhood Brain Tumor Survivors
Completed
Conditions studied: Brain Tumors
In brief
Children treated with radiation therapy for brain tumors are at risk for cognitive problems. These problems have typically been demonstrated on global cognitive measures including measures of intellectual functioning (IQ). Identification of specific areas of impairment can assist in isolating vulnerable brain areas and developing targeted interventions. In this study, we assess brain tumor survivors, solid tumor controls and healthy sibling controls using measures of working memory (online maintenance and manipulation of information) in order to identify a specific cognitive process that may underlie the observed decline in IQ. We are also exploring relationships among working memory performance with IQ, clinical characteristics and a specific genetic factor of interest.

You may qualify if…
- Brain Tumor Patients
- Treated for a primary central nervous system (CNS) tumor with conformal radiation therapy and enrolled on the institutional protocol RT-1
- Initiated radiation therapy at least 2 years prior to enrollment with no evidence of recurrent disease
- Age 8-18 years inclusive at the time of enrollment, with sampling to obtain a broad cross-section of participants in terms of age, tumor location and time since RT initiation
- English as the primary language
- Research participant and one parent willing to participate and provide consent/assent according to institutional guidelines
- Solid Tumor Patient Controls
- Treated for a solid tumor (i.e., Ewing's sarcoma, osteosarcoma, soft tissue/rhabdomyosarcoma, neuroblastoma or Wilms tumor) at St. Jude without CNS directed therapy - Diagnosed at least 2 years prior to enrollment
- Age 8-18 inclusive at the time of enrollment, with age, gender and race sampling to broadly match the brain tumor group
- English as the primary language
- Research participant and one parent willing to participate and provide consent/assent according to institutional guidelines
- Sibling Controls
- Healthy sibling controls- siblings of St. Jude patients treated for a brain tumor (not necessarily on RT-1)
- Age 8-18 inclusive, with age and gender sampling to broadly match the patient group
- English as a primary language
- Research participant and one parent willing to participate and provide consent/assent according to institutional guidelines
You may not qualify if…
- Brain Tumor Patients
- Significant impairment in global intellectual functioning (operationalized as an estimated IQ less than 70 as indicated by most recent RT-1 testing)
- History of documented CNS injury or disease predating cancer diagnosis
- History of documented Attention Deficit Hyperactivity Disorder (ADHD) predating cancer diagnosis by at least one year (must have been diagnosed by a physician with medication prescribed)
- Treatment with psychostimulant or psychotropic medication within two weeks of study enrollment
- Sensory or motor impairment that would preclude valid cognitive testing
- Solid Tumor and Sibling Controls
- Significant impairment in global intellectual functioning (operationalized as a history of special education in a self-contained classroom)
- History of documented CNS injury or disease
- History of documented Attention Deficit Hyperactivity Disorder (ADHD) (must have been diagnosed by a physician with medication prescribed)
- Treatment with psychostimulant or psychotropic medication within two weeks of study enrollment
- Sensory or motor impairment that would preclude valid cognitive testing
