Cognitive Training in Attenuating Attention Deficits/Child Treatment for Cancer

Primary Objectives: 1. To evaluate the feasibility of enrolling children and adolescents with newly diagnosed brain tumors, leukemia, or lymphoma in a program designed to prevent the academic and cognitive declines that commonly result following central nervous system (CNS) disease and treatment. Hypothesis 1: Despite the rigors of disease and treatment, children and adolescents will be able to participate in the CTP while they are receiving treatment for cancer. The high participation of our patients in routine school activities during treatment suggests that they will have the energy and interest required to participate in cognitive training. 2. To evaluate whether a Cognitive Training Program (CTP) might be helpful to patients in preventing attention deficits that commonly result following CNS disease and therapy. Hypothesis 2: Patients in the CTP arm of the study will show fewer declines in neurocognitive performance at the end of training and again six months later, as compared with the control group who will receive the usual services provided by the Education Program in Pediatrics. 3. To explore the relationship between CTP treatment compliance and stability/decline in cognitive and academic performance in children and adolescents who are being treated for brain tumors, leukemia, and lymphoma. Hypothesis 3: Level of compliance with CTP treatment will be predictive of a patient's performance on neurocognitive measures.
