It should be emphasized that at the present stage there is no consensus achieved 
regarding the etiopathogenesis of BMS. Almost all researchers point to lots of 
factors, simultaneously participating in genesis and development of BMS and at 
the same time most of them agreed on one - psychological factors play a crucial 
role in formation and maintenance of painful sensations. The aim of the study 
was the identification of psychological or psychiatric deviations (changes) 
among the patients with BMS to perform an adequate differentiated therapy. 
Clinico-psychological examination (dentist, neurologist, psychiatrist) was 
carried out in 39 patients from 46 to 70 years of age. Among them women - 36 and 
men - 3. To identify clinical types of BMS a classification of P.J. Lamey (1996) 
was used and as a result, depression, insomnia, cancerophobia, severe neurologic 
disorders, phobic syndrome were revealed. Three main categories - a chronic 
somatoform dysfunction (23 cases), chronic vegetative disorders (8), and chronic 
pain phenomenon (12) were identified. Only in one case was revealed a paranoid 
syndrome. Alongside with the well-known scheme of treatment (antidepressants, 
anticonvulsants, or neuroleptics) Psychotherapy was conducted, while EEG-feed 
back (Biofeed back, Neurofeed back) method was used for the first time. A number 
of important decisions were made the most important of which are the following: 
BMS - must be regarded as a psychosomatic problem rather than a psychiatric 
disorder. In addition to psychotherapy, using of EEG - feedback method greatly 
improved patients' condition and in 4 cases BMS clinical manifestations were 
evened-out completely.
