Neurofibromatosis Type 1 clinical trials

Analysis of Data Collected From Individuals Administered Neurobehavioral Assessments

Background: - People with chronic illness often are at risk for developing neurobehavioral problems due to effects of the disease or associated treatments. These problems may include cognitive impairments involving problem-solving, remembering things, paying attention, and understanding and using language, or emotional functioning or quality of life. - The National Cancer Institute Medical Illness Counseling Center Neuropsychology Group has collected data from neurobehavioral evaluations of infants, children, adolescents and adults with chronic illnesses enrolled in NIH protocols since 1987 and continues to collect data from patients enrolled in current protocols. - The data from these evaluations, along with demographic and medical information are stored in an NIH computer database. - Investigating the neurobehavioral functioning of patients with chronic illness is important for identifying and monitoring the effects of the disease and treatments over time, determining possible at-risk subgroups, evaluating response to therapy, and recommending educational and rehabilitative interventions. Objectives: -To learn about how certain illnesses or treatments may affect a person s cognitive abilities, emotional functioning and quality of life. Eligibility: - Patients currently enrolled in NIH studies who are having neuropsychological testing or completing quality-of-life questionnaires as part of that study. - Data obtained from infants, children, adolescents, and adults administered neurobehavioral assessments as part of a past or future NIH protocol. Design: - This study does not involve any extra tests or questionnaires; it uses information collected from evaluations that subjects have already completed or will complete as part of other NIH studies. - Information about participating patients that may help elucidate how cognitive abilities, emotional functioning, and quality of life are affected in people with chronic illness may be collected and stored.
