RESUMO
BACKGROUND AND PURPOSE: Subcortical white matter (WM) plays an important role in speech production and language processing. Most frequently, cerebral WM lesions are secondary to small vessel disease in patients with vascular risk factors. We report the case of a 53-year-old man with history of hypertension and ischemic subcortical lesions, who presented with speech difficulties and mild cognitive impairment. METHODS: Language and cognitive assessment included Boston Diagnostic Aphasia Examination, Boston Naming Test, Rey Auditory-Verbal Learning Test, Rey-Osterrieth Complex Figure Test, Trail Making Test A and B, Wisconsin Card Sorting Test, Scale for Evaluation of Perceptive Characteristics of Voice and Speech, and Multidimensional Evaluation of Speech and Voice. RESULTS: Brain MRI showed ischemic WM lesions and lacunar infarcts in the brainstem and right cerebellum. Cognitive testing revealed mild cognitive impairment, predominantly affecting attention and executive functions. Speech and language analysis demonstrated dysarthria, dysphonia with hypophonia, and imprecise articulation, as well as short rushes of speech, palilalia and mild subcortical dysphasia. CONCLUSIONS: Neurolinguistic and acoustic analysis in patients with ischemic WM lesions can provide additional information in the understanding of language and speech disturbances, and can assist in patient management.
