Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
II. Continue the search for a cytogenetic and/or DNA marker. III. Study the effects of cholinergic drugs based on preliminary evidence for reduced levels of brain acetylcholine, while continuing supportive care to modify seizures, respiratory abnormalities, and motor disturbances, and improve nutrition, behavior, and learning.
IV. Identify targets for future therapeutic interventions, e.g., growth factors, to influence neurologic recovery.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Selected patients with malnutrition are given night feedings of Pediasure with Fiber by nasogastric tube. Specific recommendations for feeding techniques and diet are made.
Selected patients with seizures or severe hyperventilation and progressive rigidity are nonrandomly assigned to dextromethorphan or topiramate therapy.
Oral dextromethorphan is maintained 6 months to 1 year; duration of therapy depends on response. Oral topiramate is given for 6 months to 1 year, and Aricept for 6 months to 1 year.
Concurrent anticonvulsants may require dose adjustments while on above protocols. Supportive care for constipation, scoliosis, and weight loss is allowed.
