RESUMO
Complex children examination with alalia was based the analysis by the role of subcortical brain structures for the formation of speech was investigated. Alalia is systemic speech underdevelopment in children, which violated all the components of speech. Evaluation of the functional state of brain structures on the EEG has allowed to distinguish the two groups, which depend on the nature of changes in bioelectric activity (BEA). The first group is one with the changes of alpha rhythm and/or local changes in BEA predominantly in the left hemisphere, the second group with violations ofbrainstem origin, mainly generalized EEG changes. A comprehensive analysis of clinical data has allowed to suggest the basis of the formation alalia lies subcortical structures lesion of the left hemisphere of the brain and stem departments of one. The analysis of perinatal risk factors has allowed to hypothesize about the connection of subcortical structures lesion with antenatal complications in the first half of pregnancy.
