Abstract
Objectives Aim of the study is to evaluate the oral-motor speech disorders in Alzheimer's disease as compared to the speech disorders occurring in the physiological process of aging. Methods We examined 22 patients with Alzheimer's disease (AD) at the age of 68 to 90 years. The control group (C) consisted of 22 people. The test has 5 parts: dialogic speech, descriptive speech, naming, repeating and speaking automated verbal sequences. Results Statistically significant differences between AD and C groups in the number of correct and incorrect answers were found. The greatest difference was found between AD and C groups in the descriptive speech. During the repetition of monosyllabic and polysyllabic words in AD occurred significantly more often the articulation errors on repeated speech productions of the same utterance. Conclusions The results confirmed the presence of oral-motor speech disorders in Alzheimer's disease. It was stated articulation errors, periphrases and jams. These errors occur in the structure of lexical-semantic and phonological system of the language. No abnormalities were noted in the area of grammar.
