Word-deafness (verbal auditory agnosia, agnosia for speech, agnosia for acoustic language) is the most devastating of all the disorders of the central auditory pathway in children, whether the disorder is present from infancy (dysphasia) or is acquired (aphasia). Typically, word-deaf children are mute and understand little or nothing of what is said to them; they resemble deaf children in this ...

Anomia, a difficulty in word retrieval, is one of the most prevalent disturbances in aphasic speech production. Heterogeneity in naming impairments poses a challenge to developing treatment programs for word retrieval difficulties in aphasia. Recent cognitive descriptions of word-finding impairments have been based on a two-step model of word production (Dell, Schwartz, Martin, Saffran, & Gagno...

Introduction: In this study, we reported the reliability and validity of Bedside version of Persian WAB (P-WAB-1) adapted from Western Aphasia Battery (WAB-R)1,2. P-WAB-1 is a clinical linguistic measuring tool to determine severity and type of aphasia in brain damaged patients based on Aphasia Quotient (AQ) as a functional measure. For the purposes of a quick clinical screening of aphasia in...

Background: Aphasia is a common outcome of Cerebrovascular Accident (CVA) in which clinical interventions have limited effectiveness. Some evidence suggests that noninvasive stimulation of the brain can have beneficial effects in the treatment of CVA induced aphasia. In patients with motor aphasia, repetitive Transcranial Magnetic Stimulation (rTMS) is used to facilitate long-term improvement i...

background:  the  mississippi  aphasia  screening test (mast) is a brief screening test for assessing the expressive and receptive language abilities in patients with  aphasia.  the  objective  of  the  study  was  to develop and validate the persian version of the mast (mastp) as a screening test for language disorders in patients with post-stroke aphasia. methods: this study used a cross-sect...

background & purpose: a stroke occurs when blood flow to a region of the brain is interrupted by the blockage or rupturing of a blood vessel or artery. the most prevalent cause of aphasia is stroke. a brain damage that can effect on receptive & expressive language skills is aphasia. intensive language therapy is the most effective means of treating aphasia. the ciat is one of the novel intensiv...

Recently, types of language impairment associated with damage in Broca’s area have been the focus of an increasing number of cross-linguistic studies. There are at least two reasons for this. First, it has been observed that manifestations of Broca’s aphasia differ across languages, and thus the crosslinguistic evidence is crucial in order to understand better the nature of linguistic disorders...

This article explores how consideration of acquired speech and language disorders from the perspective of neuroscience permits new insights into the content and design of therapy for people with aphasia. Key proposals are that aspects of current therapies often neglect the sensory-motor components of speech and language processing, and the interconnectivity of sensory-perceptual and motor syste...

Aphasia is an acquired language disorder with a diverse set of symptoms that can affect virtually any linguistic modality across both the comprehension and production of spoken language. Partial recovery of language function after injury is common but typically incomplete. Rehabilitation strategies focus on behavioral training to induce plasticity in underlying neural circuits to maximize lingu...
