title: Generality of the kindling phenomenon: some clinical implications.
abstract: The purpose of the present investigations was to explore the generality of the kindling phenomenon and its applicability to clinical situations. Whether local brain stimulation, electroconvulsive shock (ECS), or metrazol the consequence of periodic administration of convulsive agents was found to be the same; in each case repeated application of the agent resulted in the gradual development and intensification of convulsive symptoms (kindling). Moreover, in each case the resulting intensification was not specific to the agent being used and seemed to increase the responsiveness to convulsive agents in general. In the present studies this interaction was seen in the form of an intensified alcohol withdrawal syndrome observed 18 days after cessation of a series of metrazol injections, amygdaloid stimulations, of ECS. Thus, it appears that one of the hazards of the convulsive therapies is that they may induce enduring changes in brain function which leave the patient in a state of increased susceptibility to a variety of potentially convulsive agents.
