[Interhemispheric asymmetry in patients with cerebral autonomic disorders]

EEG CS analysis was used to study interhemispheric asymmetry (IHA) in patients with cerebral vegetovascular crises and in the control group of healthy test subjects at rest and under functional loads of the left and right cerebral hemispheres. In part of the patients the study was conducted in conjunction with drug intake. The patients manifested the smoothing out of the IHA by the rhythm at the expense of higher activation of the right hemisphere. In response to verbal load the patients manifested activation of the left hemisphere exceeding activation in healthy subjects. Non-verbal load gave rise to preserved reaction also manifesting itself by activation of the left cerebral hemisphere. It has been discovered that the EEG CS analysis readings and alterations in the IHA are closely interrelated to the presence of hypothalamic dysfunction, actual mental condition, disease standing and clinical features of the crises.
