a case of evolving post ictal language disturbance secondary to a left temporal arteriovenous malformation jargon aphasia or formal thought disorder
Cognitive Neuropsychiatry, 2006Co-Authors: Adam Zeman, Carly Rivers, Alan Carson, Uma NathAbstract:Introduction. Wernicke's Dysphasia and formal thought disorder are regarded as distinct diagnostic entities although both are linked to pathology in the left superior temporal gyrus (STG). We describe a patient with focal pathology in the left STG, giving rise acutely to a fluent Dysphasia, which gradually evolved into formal thought disorder. Method. Clinical, neuropsychological, neuropsychiatric, and neuroradiological assessment. Results. A right‐handed patient, AJ, presented acutely with a fluent Dysphasia. His speech output gradually evolved from undifferentiated jargon, through neologistic jargon, to an intelligible but bizarre form of discourse. Comprehension was relatively well preserved. Radiology revealed an arteriovenous malformation in the left middle, and inferior temporal gyri, with reduced perfusion of the left STG. Six months later his overt Dysphasia had recovered, but his speech retained some of its previous characteristics, in particular a tendency to a loose association of ideas which n...

deep Dysphasia further evidence on the relationship between phonological short term memory and language processing impairments
Cognitive Neuropsychology, 2001Co-Authors: Steve Majerus, Francoise Lekeu, Martial Vanr De Linden, Eric SalmonAbstract:We report a cognitive investigation of a case of deep Dysphasia appearing in the context of primary progressive aphasia. Over a period of 5 years, patient CO presented progressive difficulties in word finding and in oral comprehension, while nonverbal cognitive functions remained preserved. As in other deep dysphasic patients, CO's repetition performance showed marked imageability and lexicality effects, and semantic paraphasias. The same effects were observed in writing-to-dictation. Regularisation errors occurred in word reading. CO's short-term memory span was less than two words. A cognitive analysis of language processing revealed difficulties in phoneme identification and rhyme judgement, in detecting grammatical class for orally presented words, and in oral and written naming. The interpretation of CO's deep dysphasic symptoms within interactive models of language processing confirmed the importance of a phonological short-term storage impairment as an explanatory factor of deep Dysphasia.

effect of Dysphasia and dysphagia on inpatient mortality and hospital length of stay a database study
Journal of the American Geriatrics Society, 2009Co-Authors: Veronique Guyomard, Robert A Fulcher, Oliver Redmayne, Anthony K Metcalf, John F Potter, Phyo K MyintAbstract:OBJECTIVES: To examine the effect of Dysphasia and dysphagia on stroke outcome. DESIGN: Retrospective database study. SETTING: Norfolk, United Kingdom. PARTICIPANTS: Two thousand nine hundred eighty-three men and women with stroke admitted to the hospital between 1997 and 2001. MEASUREMENTS: Inpatient mortality and likelihood of longer length of hospital stay, defined as longer than median length of stay (LOS). Dysphagia was defined as difficulty swallowing any liquid (including saliva) or solid material. Dysphasia was defined as speech disorders in which there was impairment of the power of expression by speech, writing, or signs or impairment of the power of comprehension of spoken or written language. An experienced team assessed dysphagia and Dysphasia using explicit criteria. RESULTS: Two thousand nine hundred eighty-three patients (1,330 (44.6%) male), median age 78 (range 17–105), were included, of whom 77.7% had ischemic, 10.5% had hemorrhagic, and 11.8% had undetermined stroke types. Dysphasia was present in 41.2% (1,230) and dysphagia in 50.5% (1,506), and 27.7% (827) had both conditions. Having either or both conditions was associated with greater mortality and longer LOS (P<.001 for all). Using multiple logistic regression models controlling for age, sex, premorbid Rankin score, previous disabling stroke, and stroke type, corresponding odds ratios for death and longer LOS were 2.2 (95% confidence interval (CI)=1.8–2.7) and 1.4 (95% CI=1.2–1.6) for Dysphasia; 12.5 (95% CI=8.9–17.3) and 3.9 (95% CI=3.3–4.6) for dysphagia, 5.5 (95% CI=3.7–8.2), 1.9 (95% CI=1.6–2.3) for either, and 13.8 (95% CI=9.4–20.4) and 3.7 (95% CI=3.1–4.6) if they had both, versus having no Dysphasia, no dysphagia, or none of these conditions, respectively. CONCLUSION: Patients with dysphagia have worse outcome in terms of inpatient mortality and length of hospital stay than those with Dysphasia. When both conditions are present, the presence of dysphagia appears to determine the likelihood of poor outcome. Whether this effect is related just to stroke severity or results from problems related directly to dysphagia is unclear.
