Electroencephalography with mental illnesses

Electroencephalography with mental illnesses are used for diagnostic purposes and to address issues of pathogenesis of different diseases, the mechanism of action of pharmacological preparations etc. As one of the methods of research of patients, electroencephalography in a psychiatric hospital does not in itself grounds for the nosological diagnosis.
The diagnosis can be established only as a result of a comprehensive, first of all clinical, research, patient. A particularly high proportion of electroencephalography in the whole complex of diagnostic tests at the decision of a question on existence and localization center organic lesion in the brain, if necessary, identification and qualification of the functional state of the brain of the patient (for example, state convulsant epilepsy different origin) and monitor the dynamics of this condition, the treatment efficiency.
The benefits of EEG studies to a large extent depends on the clear language of the question that arises in the analysis of the clinical picture, for permission which the patient is referred for this study. The nature of the issue depends on the choice of adequate variants of the study. If the main problem is topical diagnosis, it is advisable to use a large number of leads (in particular, electroencephalography) and their combinations, sometimes apply basal nasopharyngeal electrode. If the question about epileptic or nonepileptic nature of seizures, appropriate determination of the electrical activity of the brain under the influence of the bright light flashed, hyperventilation, investigation of the interaction of analyzers. To identify functional changes in the brain useful evolution of electrical activity under the influence of light and sound stimuli, emotionally significant stimuli, different types of mental activity.
