Summary:

Various autonomic nervous system (ANS) disorders exist in 25-80% of the general population. Seniors affected by chronic cerebral ischemia (CCI) are subject to the development of autonomic disorders. Purpose: to carry out the analysis of autonomic dysfunction in subjects with CCI. Material and Methods. Autonomic status was evaluated using autonomic function tests. All patients underwent cardiointervalography. Heart rhythm variability was estimated by mode, amplitude, variation range, power of waves of various frequency, coefficient of vagosympathetic balance etc. as measured by "Rhythm-MET" system. One hundred fifty one patients aged 48-93 years were examined and distributed to three groups depending on the degree of severity of CCI. Results were statistically processed using Statistica 6 software. Results. Patients with CCI had differences in autonomic function parameters which had multidirectional character and were dependent on sympathetic-parasympathetic balance and CCI stage. The obtained data demonstrate that prevalence of sympathetic influence was observed in 52.8% patients with I grade CCI, in 64.8% patients with II grade CCI and prevalence of parasympathetic

Summary:

The goal is to study the cerebral blood flow and psychometric characteristics in veterans of Afghanistan with early forms of chronic brain ischemia. Material and Methods. The study included 74 veterans of the Afghan war aged from 45 to 55 years: group 1, 28 people with NPNKM; Group 2-28 patients with circulatory encephalopathy stage 1; group 3-18 healthy persons. Doppler examination of cerebral vessels was carried out on the unit «Smart-lite». Reactive and personal anxiety of patients was assessed using the scale of Spielberger, evaluation of the quality of life through the test SAN. Determining the level of neuroticism and psychoticism was conducted by the scale of neuroticism and psy-choticism. Results: The study of cerebral blood flow in the Afghan war veterans showed signs of insolvency of carotid and carotid-basilar anastomoses, hypoperfusion phenomenon with the depletion of autoregulation, violation of the outflow of venous blood at the level of the microvasculature, accompanied by cerebral arteries spasm. More than 40% of patients with early forms of chronic brain ischemia had high personal anxiety, low levels of well-being and activity, with maximum expression of dyscirculatory hypoxia. Conclusion. Readaptation of veterans of Afghanistan is accompanied by the changes in psychometric performance and the formation of the earliest forms of brain chronic ischemia associated with inadequate hemodynamics providing increased functional activity of the brain and the inefficiency of compensatory-adaptive reactions.
