title: [Characteristics of functional status of the autonomic nervous system in patients with diabetes mellitus].
abstract: OBJECTIVE
  To evaluate prognostic significance of autonomic nervous system (ANS) dysfunction in patients with diabetes mellitus (DM).
  
  
  METHODS
  The examination covered 51 DM type 1 patients aged 18 to 43 years with DM history from 6 months to 31 years. ANS function was assessed by spectral analysis of cardiac rhythm with calculation of indices of rhythm "rigidity", centralization and activity of subcortical centers.
  
  
  RESULTS
  DM progression and development of its late complications were accompanied with dissociation of tonicity of the sympathetic and parasympathetic ANS components, augmentation of regulatory systems tension. Evidence was obtained for correlation of relative values of SW1 power with severity of DM (r = 0.88) and its microvascular complications (r = 0.70). Decreased power of MW2(%) in the tilt test predicts development of orthostatic hypotension.
  
  
  CONCLUSIONS
  Involvement in the regulation of the central contour of ANS management reflects adaptation failure and is prognostically significant.
