[Epilepsy by looking at patterns].

The author, after pointing out the rare occurence and peculiarities of pattern-sensitive forms of epilepsy, reports the case of a seven-year-old boy with infantile cerebral paresis characterized by symptomatic attacks, who was observed to show absence-like conditions when looking at small-checkered patterns of nylon fabric. Grasping and looking at such fabrics assumed the form of an addiction, with a sense of pleasure being believed to be derived therefrom. Although anticonvulsive therapy resulted in attacks of epilepsy being no longer detectable clinically and by electroencephalography, seizures were still triggered by looking at patterns. Also discussed in this article is the problem of transition from real to psychogenic attacks.
