[About musicogenic epilepsy (author's transl)].

A case of musicogenic epilepsy or psychomotor seizures supervening whenever the patient hears a certain tune is presented. Nearly 70 cases of musicogenic epilepsy have been documented so far. The findings in these cases including those encountered by ourselves may be summarized as follows: Musicogenic epilepsy is more common among middle-aged persons. In an unexpectedly large proportion of cases the cause is unknown. Among the organic causes, head injury is of the highest incidence. It is quite unlikely that brain bumor is responsible. There is no dementia or mental retardation as in some forms of reflex epilepsy. The seizure is overwhelmingly of the psychomotor type. The EEG pattern often suggests temporal lobe epilepsy. There seems to be no cerebral dominance. Different kinds of music can be the inducer, ranging from those primarily intended to stimulate the sense to those appealing to affect. The activating mechanism of the condition still remains obscure. In the strict sense of the word, the condition cannot be termed reflex epilepsy.
