[Neurocirculatory dystonia in patients with a chronic focal infection: the mechanisms of its formation and development].

Clinical manifestations of neurocirculatory asthenia (NA) were analyzed in 604 patients with associated chronic focal infection. It is shown that the latter infection produces negative effects on clinical symptoms of NA, its course, temporary disability and effectiveness of treatment. Vegetative reactivity and vegetative activity in NA patients with the infection were affected to a greater degree than in NA patients without the focal infection. The role of afferent impulses from the nasopharynx reflexogenic zone in the genesis of clinical specificity and vegetative regulation defects in NA patients is discussed.
