In this study, for the first time, the photic driving reaction in patients with different disorders of the functional state of central nervous system caused by cerebrovascular conditions of different severity was examined by wavelet analysis of electroencephalographic (EEG) fragments. The background fragments of EEG in the group of patients with vegetative-vascular dystonia, are characterized by lower values of the wavelet spectrum energy in the alpha range than the fragments in the control group. In patients from the groups of vertebrobasilar insufficiency and atherosclerotic damage of cerebral blood vessels, the values of energy in delta range is even lower. The wavelet analysis of reactive patterns has demonstrated the different photic driving of beta, theta and alpha ranges in the patients of various groups. The study demonstrates the possibility of quantitative estimation of the human brain lability of light stimulus perception by the wavelet analysis. The results can be used for the adequate choice of treatment for a patient with cerebrovascular disorder. |
