[Insufficient success in the treatment of epilepsy--mistakes in therapy or resistance to therapy?].

Frequently either no results or inadequate results are obtained in the therapy of canine and feline epilepsy. This is often not due to a primary resistance to therapy, but rather, caused by other factors and, above all, by mistakes made in therapeutic management. The possible causes of a faulty or insufficient treatment and the most common mistakes made in therapeutic regime are described. At the same time suggestions for an optimal course of therapy are given.
