| Summary: | Introduction: Word-finding impairments (anomia) are the most common, specific symptom of aphasia, which in adults, are most frequently caused by stroke. Although anomic difficulties usually manifest themselves in different forms of speech and involve various word classes, in very rare cases, they may involve only one category of words. This type of disorder is called category-specific anomia.Objective: The aim of the article is to describe changes regarding verbal communication in a patient with post-stroke aphasia, particularly the analysis of category-specific anomia for numbers, recognised in the long-term from the disease onset.Material and methods: The patient's language skills were assessed during the 2nd week, 3rd month (period of spontaneous recovery and early neurorehabilitation), and 12 months post-stroke (distant neuro-rehabilitation period) using the Boston Test for the Diagnosis of Aphasia and clinical trials to assess different cognitive dysfunctions that can affect the ability to name numbers.Results: The results allowed to identify the following in the patient and in the following sequence: profound mixed aphasia (2nd week post-stroke), mild and moderate language deficits (3rd month post-stroke) and an isolated anomia of numbers (12th month after stroke). Due to functional improvement, one year after the stroke, the patient performed the tasks of naming objects, activities and describing the features of objects almost without errors. In addition, he efficiently recognised and differentiated the values of numbers, correctly wrote down the numbers under dictation and carried out proper mathematical calculations. However, these data contrasted with profoundly low results in the trials to name numerals (digits and numbers, hours, dates), assessed as anomia of numbers.Conclusions: Anomia of numbers is a very rare post-stroke language deficit that can be diagnosed in people with aphasia after the withdrawal of co-existing language disorders and the exclusion of possible causes, other than the nominating ones, of incorrect verbal responses to numerical material. |
