[Differential diagnostic significance of symptoms of collapse following epileptic seizures].

Two groups of patients were studied: group 1 with a brain tumor and epileptic syndrome and group 2 with epilepsy of traumatic or infectious origin. In both diseases transient collapse symptoms occurred in the post-seizure period. The development of these symptoms was analysed. It was established that with the recurrence of the paroxysms in cases with cerebral new growths the transient collapse change to permanent ones which in turn become deeper from seizure to seizure. In patients with epilepsy of traumatic or infectious etiology, no change of transient collapse to permanent ones of intensification of the latter was encountered. The dynamic symptoms described are of differential diagnostic importance in distinguishing these diseases.
