MRI Language Studies in Young Children
This study will use magnetic resonance imaging (MRI) to investigate language function in children-that is, how language skills such as naming objects, understanding spoken language and reading are organized in the brain. The study focuses on children between 4 and 7 years old. Children 8 to 12 years old and adults will be studied before the younger children to test study paradigms appropriate for pre-literate children. The results of this study will help evaluate the usefulness of MRI in identifying language function and location and may improve the treatment of children with seizures.
Right-handed, native English-speaking adults and children between 4 and 12 years of age may be eligible for this study. Candidates will be screened with a routine neurological examination. Children will also undergo neuropsychological testing (standard tests of language, memory, perception and attention) either at the screening visit or at a later time. Parents will fill out a form to identify children with attention deficit and hyperactivity disorders. These children will be excluded form the study.
All participants will undergo MRI scanning of the brain while performing a task designed to test a language skill, such as identifying a picture or listening to or reading a word. The MRI detects changes in blood properties in the areas of the brain that perform each task. Before the MRI, children will be rehearsed for the tests and will have a session in the scanner to know what to expect and feel more at ease during the actual test. The time in the MRI machine is usually between 15 and 20 minutes, but will be no more than 40 minutes for children 8 to 12 years old, and not more than 20 minutes for younger children. Children may be requested to have up to five MRI sessions to test different brain functions or confirm findings.
