Classical and other differentiable types of syndrome aphasia
The systemic decay of speech thinking is caused by organic damage to the head cortex of various etiologies. Most often, the mechanism of development of the syndrome of aphasia is a cerebral stroke in the basin of the left anterior, middle and posterior cerebral arteries. However, the clinic has aphasia, which is not provoked by cortical strategic foci in the left hemisphere of the brain. With atypical aphasia, the focus is localized in the right hemisphere or in the deep subcortical areas; there is no specific strategic focus; complex neurodegenerative changes, etc. are determined. In each case, a specific type of atypical aphasia develops. In general, all clinical forms of aphasia (both typical and atypical) are differentiated proceeding from the mechanism (lesion focus), leading to the development of speech syndrome. The specificity of the symptoms of each individual patient is individual, as it is interrelated with hereditary mechanisms and its life experience, capable of altering both the function of the brain and its structure.
