Clinical and electroneurophysiological characteristics of episodic tension headache

Abstract

On the basis of clinical, neuropsychological and electroneurophysiological studies by the method of cluster ana lysis of 134 patients with episodic strain headache, they objectively were divided into two groups, differing by the severity and course of the disease. Increase in reflex excitability of neuron structures of cerebral trunk is shown to be the most significant electroneurophysiological pheno menon in episodic strain headache, and this characterizes objectively insufficiency of mechanisms of central inhibition, specifically, on the level of founder inhibiting inter neurons. Hyperreflexion of segmental apparatus of cerebral trunk serves probably as one of the final pathogenetic links in realization of syndrome of long-term tonic spasm of pericranial muscles in headache of strain.
