The neurocutaneous disorders comprise a large group of neurological syndromes that feature skin lesions and often eye lesions, central and peripheral nervous system tumors, brain malformations, mental retardation, psychiatric symptoms, or seizures. Neurocutaneous syndromes have been known for centuries, but recent research into their cellular, biochemical and molecular-genetic basis has pointed to an essential need for a genotypic nosology. In this book, a distinguished team of editors and authors provides an authoritative, illustrated, up-to-the-minute review of the current understanding of phenotype-genotype relationships in these disorders, as well as their recognition, investigation and treatment. It will be essential reading for all neurologists as well as dermatologists, geneticists and pediatricians.
