[Clinico-pathogenetic variants of neurocirculatory dystonia in patients with a chronic focal infection of the upper respiratory tract].

Particular features have been studied of clinical course of neurocirculatory dystonia (NCD) in 604 patients with chronic focal infection (ChFI) of upper respiratory tract. Comprehensive paraclinical examination of patients included the analysis of actual psychoemotional state and certain psychophysiological parameters such as time for simple and complex sensomotor reaction, memory, attention; status of vegetative regulation (tone, reactivity, vegetative security of activity) and its neurohumoral and metabolic provision; adaptive potentialities of vegetative, neuroendocrine and cardiorespiratory systems to mental, psychoemotional and physical demands; tonsillocardiac and palatocardiac reflexes according to an original methodology. Described for the first time are two clinico-pathogenetic variants ("peripheral" and "central") of NCD in patients with ChFI, which can be distinguished by severity of clinical manifestations, as well as by degree of disturbances in homeostasis and adaptation in vegetative, neurohumoral, somatic and psychoemotional spheres. Practical significance of the aforementioned variants consists in feasibility of employing pathogenetic approaches to the treatment of NCD and ChFI patients. Pathogenetic method of treatment of patients with NCD and ChFI is discussed.
