Four hundred and twenty patients admitted to the veteran's hospital with neuro- and psychopathology have been examined. Along with clinical, neurological, psychiatric and psychological methods, electroencephalography, computed tomography, electrocardiography, ultrasonic and X-ray methods for nervous system investigation as well as biochemical and immunological blood examination were used. The following disorders were singled out: (1) mental disorders--neurosis, personality pathology, post-traumatic stress disorder and different types of addictions (alcoholism, drug dependence): (2) consequences of craniocerebral and other injuries; (3) psychosomatic pathology. The prevalence, clinical manifestations and dynamics of each group of disorders are studied and their patho- and sanogenesis in terms of theory of functional systems are regarded.
