[Autonomic system disorders in patients with myasthenia gravis]

Using a set of techniques, segmentary and nonsegmentary autonomic nervous system compartments were studied at rest and under stress. Parasympathicotonia, on the background of general deficit of ascending nonspecific brain activity, was found to characterize myasthenia in general. A decrease of nonspecific brain activity level is combined with elevated anxiety. However, one may distinguish a generalized type of the disease by the presence of dissociation of the autonomic nervous system compartments due to sympathicotonia.
