2 - An 83-year-old right-handed woman presented with sudden right sided hemiparesis, somnolence and loss of normal speech. - Speech was non-fluent with semantic paraphasias and word-finding difficulties. Word repetition and comprehension was normal. Afzal et al. Vignette

3 Afzal et al. Figure 1 Figure 2

4 Afzal et al. -MR brain showed an area of restricted diffusion in the left thalamus consistent with acute infarction. -Speech fluency returned to normal after two days with occasional dysnomia and parapahsias. -Left thalamic infarcts can result in aphasia which is characterized by lexical- semantic deficits and intact word repetition; fluency and comprehension are variably affected (1). - Thalamic aphasia has been hypothesized to result from disconnection between cortical language centers and thalamic nuclei (1,2).
