Розробка критеріїв діагностики порушень міжпівкульної асиметрії головного мозку Head Loganovsky Konstantin Nikolaevich, Registration Date 20-02-2006 Organization Research Centre for Radiation Medicine popup.description2 Object of study: 60 сlean-up workers with mental disorders, irradiated in doses 0,3-1,0 Sv; 30 not irradiated patients with mental disorders; 30 practically healthy persons. Purpose of study - to develop a protocol of determination of dominant hemisphere of cerebrum, right- and left-handed, unified diagnostic of mental disorders. To reveal effects of ionizing radiating in doses 0,3-1,0 Sv on hemisphere asymmetry changes. Methods of study - clinical neurological and psychiatric, neuropsychological, psychodiagnostical, neurophysiological, statistical. It was designed and approved protocol of determination of dominant hemisphere of cerebrum, right- and left-handed, and unified diagnostic of mental disorders and diseases of nervous system; structure of database. Neuropsychological by the particularity of organic mental disorders beside persons, irradiated in doses 0,3-1,0 Sv was a reduction of function activity of dominant hemisphere of cerebrum and compensatory raising of function of nondominant hemisphere. Neuropsychological markers of ionizing radiating in doses 0,3-1,0 Sv was verify. There were revealed particularities of neurofunctional breaking in doses 0,3-1,0 Sv and asymmetry of cerebral hemodynamics. Neuropsichyatric effects are concluded in increase an negative psychopatological symptomatic, increase relative delta-power, in fronto-temporal area particularly, and reducing absolute teta-power in temporal area of left hemisphere, diffusive reducing of alpha-power. The conception of cerebrum radiosensitivity and primary damage localization in cortico-limbic system of dominant (left) hemisphere was proved.
