DIAGNOSTIC TECHNIQUE FOR EARLY FORMS OF CEREBROVASCULAR INSUFFICIENCY Russian patent published in 2011 - IPC A61B8/00 A61B8/06 A61B5/29 A61B5/476 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to neurology and functional diagnostics, and aims at diagnosing early forms of cerebrovascular insufficiency. It involves transcranial Doppler sonography to evaluate the blood circulation values, a resistance index, with performing a counterlateral head rotation test. It is added with echocardiography to type central hemodynamics. Also, computed electroencephalography is performed. A heart rhythm variability is examined that involves orthostatic and antiorthostatic tests. Also, immune homeostasis is analysed. If observing an eukinetic type of central haemodynamics, hypersynchronous EEG-patterns; impaired adaptation-compensation potential with no load test decrease as shown by heart rhythm variability examination, lymphopenia, total metabolite growth, humoral link activation, hypoperfusion in one of a cerebral vascular circulation, initial manifestations of cerebrovascular insufficiency is diagnosed. A hypokinetic type of central haemodynamics, desynchronous EEG-patterns, considerable load test decrease of adaptation-compensation potential, lymphocytosis, hypoperfusion in two cerebral vascular circulations enable to diagnose stage 1 dyscirculatory encephalopathy.

EFFECT: technique provides differential diagnostics of the initial manifestations of cerebrovascular insufficiency and stage 1 dyscirculatory encephalopathy in mature-aged patients at the stage of observing no anatomical changes of vascular patency.
