The aim: A comprehensive assessment of the state of the autonomic nervous system and cerebrovascular reactivity of the cerebral blood flow in the patients with the headache
accompanied by arterial hypertension (AH) and somatoform autonomic dysfunction (SAD).
Materials and methods: We conducted the clinical, autonomic regulation and Doppler sonography examination of 124 young patients (18-45 years old), including 51
men and 73 women in the conditions of the clinical base of the Kharkiv Medical Academy of Postgraduate Education in 2018-2021. All patients with cephalgias were divided
into three groups: with AH stage II (Group I - 41 patients), AH stage I (Group II - 40 patients), SAD (Group III - 43 patients). The control group consisted of 50 patients of the
corresponding gender and age
Results: The intensity of cephalalgia in patients with SAD was maximum. The autonomic tone (AT) was changed in 68.5%examined patients. It had a pronounced shift towards
sympathicotonia. According to the visual analogue scale the maximum intensity of cephalgias was against the sympathicotonia. In the groups with organic lesions of the
cerebral vessels the latent period delay was registered with the progression of the organic pathology. The regularity was revealed - the shortening of the evoked skin sympathetic
potentials latency with the severity of cephalalgia, which can be interpreted as an increase in ergotropic effects with the realisation of the pain syndrome. The obtained data on
the state of the AT indicate the depletion of the ergotropic processes with the progression of cerebral ischemia with a known increase in parasympathicotonia. In the patients
of SAD group the CrCO2 and KrFNTvalues were significantly increased, in AH stage I group they slightly exceeded the standard values , in AH stage II group they were reduced.
The reactivity to the orthostatic loads and functional metabolic test in all groups exceeded the control values.
Conclusions: 1. The cephalgic syndrome is one of the main symptoms of the autonomic dysfunction and arterial hypertension; the frequency and intensity of the headache
increases with the hyperreactivity of the sympathetic system. 2. The SSP data indicate that the sympathetic activity triggers and maintains the pain syndrome, and can also be
realized in the form of arterial hypertension. 3. The dysfunction of the central link of the GSR indicates the instability of the autonomous regulation, the work of the limbic-reticular
complex, which is clinically manifested by the changes in the cerebral vascular tone. 4. The cerebrovascular hyperreactivity as a sign of the search for the optimal sanogenetic
variant of the cerebral hemodynamics in patients with SAD and AH stage I occurs predominantly due to the vasodilatory component. 5. In the patients with AH stage II the
vasoconstrictor reactions are observed with the depletion of the vasodilation reserves, which is a marker of the autoregulation failure.
