Somatosensor Induced Potentials in Diagnosis of a Non-systemic Vertigo in Patients with a Dyscirculatory Encephalopathy
Aim of investigation is a study of the non-systemic vertigo mechanisms in patients with a dyscirculatory encephalopathy with a use of the somatosensor induced potentials.
Materials and Methods. 40 patients with a dyscirculatory encephalopathy of the I and II stages with a non-systemic vertigo at the age of 45—60 years are examined. An investigation of the somatosensor induced potentials from three levels: lumbar, cervical and cranial ones, was accomplished. A latency of cerebral components N20, P23, N30, P45 was assessed.
Results. A trustworthy increase of the somatosensor induced potential component P45 latency testifies to the afferent way function insufficiency in a frontoparietal area.
Conclusion. A verification of the non-systemic vertigo pathogenetic mechanisms in patients with a dyscirculatory encephalopathy permits to speak about the differentiated therapy expediency in a further elaboration.
