METHOD FOR DIFFERENTIAL DIAGNOSTICS OF ETIOLOGICAL FORMS OF DISCIRCULATORY ENCEPHALOPATHY AT DIFFERENT TYPES OF ARTERIAL HYPERTENSION FLOW Russian patent published in 2007 - IPC A61B5/00 A61B5/02 

FIELD: medicine, neurology.

SUBSTANCE: it is necessary to calculate discriminant functions: Z_{AH-without AH}=6.763-0.037X₅-0.378X₉-0.596X₁₇-0.506X₁₉-1.893X₂₉-0.274X₃₀, Z_{AH without C-AH with C}=12.044-3.340X₂+0.352X₂₁-0.616X₂₅-2.695X₄₂-0.790X₅₄, where Z_{AH-without AH} - the criterion of differential diagnostics of the states "discirculatory encephalopathy at arterial hypertension - discirculatory encephalopathy without arterial hypertension", Z_{AH without C-AH with C} - The criterion of differential diagnostics of the states "discirculatory encephalopathy at arterial hypertension without crises - discirculatory encephalopathy at crisis flow of arterial hypertension", X₂ - sex, X₅ - concomitant diseases, X₉ - the type and the quantity of acute disorders of cerebral circulation, X₁₇ - the level of location of unilateral hemispherical foci, X₁₉ - localization of stem foci, X₂₁ - distribution of cortical atrophy and underlying white substance in cerebral lobes, X₂₅ - lateralization of periventricular atrophy and its connection with focal lesion, X₂₉ - widening of perivascular spaces, X₃₀ - the syndromes of motor disorders, X₄₂ - the presence of paroxysmal disorders of consciousness, X₅₄ - the degree of asthenic manifestations; the values for patients' states should be identified according to "the patient's history on trials at encephalopathy". At Z_{AH-without AH} value being > 0.376 one should diagnose discirculatory encephalopathy without arterial hypertension, at Z_{AH-without AH} <=0.376 - discirculatory encephalopathy with arterial hypertension, at Z_{AH without C-AH with C} > 0.362 one should diagnose discirculatory encephalopathy with arterial hypertension without crises, at Z_{AH without C-AH with C} <=0.362 - discirculatory encephalopathy with crisis flow of arterial hypertension. The innovation increases the significance of differential diagnostics due to registering comprehensive complex trial in such patients.

EFFECT: higher accuracy of diagnostics.
