Intrahemispheric Perfusion in Chronic Stroke-Induced Aphasia
Stroke-induced alterations in cerebral blood flow (perfusion) may contribute to functional language impairments and recovery in chronic aphasia. Using MRI, we examined perfusion in the right and left hemispheres of 35 aphasic and 16 healthy control participants. Across 76 regions (38 per hemisphere), no significant between-subjects differences were found in the left, whereas blood flow in the r...
متن کاملThe Relationship Between Memory, Type, and Severity of Aphasia With Confrontation Naming in Post-Stroke Patients With Chronic Aphasia
Objectives: The brain’s widespread neural functions lead to aphasia in which the patients experience difficulties in cognitive and language functions. Memory, type, and severity of aphasia are associated with language and the naming process. In the current study, we investigated the relationship between memory, type, and severity of aphasia using the confrontation naming test in post-stroke pat...
متن کاملConstraint-induced therapy of chronic aphasia after stroke.
Patients with chronic aphasia were assigned randomly to a group to receive either conventional aphasia therapy or constraint-induced (CI) aphasia therapy, a new therapeutic technique requiring intense practice over a relatively short period of consecutive days. CI aphasia therapy is realized in a communicative therapeutic environment constraining patients to practice systematically speech acts ...
متن کاملTherapy-induced neuroplasticity in chronic aphasia.
Research on the neural substrate of aphasia recovery has consistently increased since the advent of functional neuroimaging. The evidence from therapy-induced aphasia recovery studies shows that better recovery results from the reactivation of left hemisphere function; still, the specific left hemisphere key areas that sign successful outcome with a specific therapy approach remain to be identi...
متن کاملRelation between aphasia and arcuate fasciculus in chronic stroke patients
BACKGROUND The role of the arcuate fasciculus (AF) in the dominant hemisphere in stroke patients with aphasia has not been clearly elucidated. We investigated the relation between language function and diffusion tensor tractography (DTT) findings for the left AF in chronic stroke patients with aphasia. METHOD Twenty five consecutive right-handed stroke patients with aphasia following lesions ...
