[Electroencephalographic studies in phacomatosis (author's transl)].

Reports on studies devoted entirely to the results of electroencephalographic recordings in phacomatosis are not available, and the authors review the large number of cases found throughout the published literature. Based on the information obtained and the results of their personal experience, they summarize the clinical findings, characteristic anomalies, and E.E.G. changes in tuberous sclerosis, neurofibromatosis, Sturge-Weber and von Hippel-Lindau diseases, and ataxia telangiectasia. Electroencephalographic studies can contribute to the diagnosis and follow-up of these affections.
