BACKGROUND Implicit learning is a process of learning that occurs outside of conscious awareness and may be involved in implicit, exposure-based language training. However, research shows that implicit learning abilities are variable among individuals with aphasia, and it remains unknown whether individuals who show basic implicit learning abilities also benefit from implicit language training....

In typical right-handed patients both apraxia and aphasia are caused by damage to the left hemisphere, which also controls the dominant right hand. In left-handed subjects the lateralities of language and of control of the dominant hand can dissociate. This permits disentangling the association of apraxia with aphasia from that with handedness. Pantomime of tool use, actual tool use and imitati...

This event-related functional magnetic resonance imaging (fMRI) study reports on the impact of semantic feature analysis (SFA) therapy on the neural substrate sustaining the recovery from severe anomia in two patients: one participant was diagnosed with primary progressive aphasia (PPA) 2 years before this study; the other participant acquired aphasia 8 years before this study. The participant ...

In this paper, a historical overview of the interpretation of conduction aphasia is initially presented. It is emphasized that the name conduction aphasia was proposed by Wernicke and was interpreted as a disconnection between the temporal and frontal brain language areas; this interpretation was re-taken by Geschwind, attributing the arcuate fasciculus the main role in speech repetition distur...

The study was carried out with the aim to develop a test of syntax comprehension in Hindi language for persons with aphasia. The present study was done in two phases. First phase included development of test material and in the second phase, the test battery was administered on neuro-typical adults and persons with aphasia. The developed material consisted of five sections, namely, prepositions...

According to speech production models such as Levelt’s (1989), speech errors in aphasia can arise at different levels of processing: lexical, phonological or phonetic. It has been claimed that each type of aphasia is associated with a specific speech production disorder. Conduction aphasia is characterized predominantly by a breakdown of the phonological code, whereas Broca’s aphasia is a disor...

Aphasia describes a spectrum of speech impairments due to damage in the language centers of the brain. Insult to the inferior frontal gyrus of the dominant cerebral hemisphere results in Broca's aphasia - the inability to produce fluent speech. The left cerebral hemisphere has historically been considered the dominant side, a characteristic long presumed to be related to a person's "handedness"...

OBJECTIVE The goal for this study was to determine methods to modify outcome measures for people with aphasia and to provide beginning support for the efficacy of these suggested modifications. METHOD Twenty-nine community-dwelling people with aphasia participated. Modified outcome measures included the Stroke Impact Scale, the 36-item short form Medical Outcomes Study, Reintegration to Norma...

Aphasia intervention has made increasing use of technology in recent years. The evidence base, which is largely limited to the investigation of spoken language outcomes, indicates positive treatment effects for people with mild to moderate levels of aphasia. Outcomes for those with severe aphasia, however, are less well documented and - where reported - present less consistent gains for measure...

Language disturbances manifesting as brief periods of speech arrest occur with seizures originating in the frontal or temporal lobes. These language disturbances are usually present with other features of seizures or may occur in an episodic fashion suggesting their likely epileptic origin. Sustained but reversible aphasia as the sole manifestation of partial status epilepticus is rare, particu...
