ABSTRACT
It was established that in left hemispheric involvement, the basis of speech disorders are non-understanding the primary speech logical connections in semantic constructions. In right-sided involvement it is caused by disorders of orientation in space, reduction of critical attitude, anosognosia and is according the authors opinion "pseudosemantic" aphasia.

A three-four year dynamic study of 211 patients (age: 15-60 years) with a history of mild head injury revealed that the younger group of patients (from 20 to 30 years) showed within 3-4 years after the injury a more complete restoration of the higher nervous activity processes than patients of other age groups. In patients suffering of cerebrovascular diseases before mild head injury the dynamics of this restoration depended on the treatment carried out before the head injury.

A study is presented of 20 patients with ischemic stroke showing speech disorders. After the surgically performed extra-intracranial microanastomosis of the superficial temporal artery with branches of the middle cerebral artery there always followed an improvement of the aphasic defect. During control angiographic examination a 2% solution of novocaine was introduced into the carotid artery. Injection of the preparation into the left carotid artery produced a short-term cessation of speech while administration of novocaine into the right carotid artery did not effect the speech function. It is concluded that speech restoration occurs due to rehabilitation processes in the dominant hemisphere of the brain.
