Aphasia is one of the most common and devastating sequelae of stroke. The arcuate fasciculus (AF), an important neural tract for language function, connects Broca's and Wernicke's areas. In this review article, previous diffusion tensor imaging (DTI) studies on the AF in stroke patients were reviewed with regard to the usefulness for diagnosis (seven studies), prediction of prognosis (two studi...

Growing numbers of older adults requiring aphasia therapy create challenges for the health care system. Information and communication technology (ICT) has the potential to provide computer-mediated, self-administered aphasia therapy that complements conventional therapy. We explore overlaps in ICT for older adults and aphasia therapy applications with the goal of integrating innovative ICT in a...

Background The Aachen Aphasia Test (AAT) is still the main test in use for evaluation of aphasic deficits German-speaking individuals (Huber et al., 1983, 1984). has also been adapted to Italian language (Luzzatti 1996) and was administered 384 people with aphasia (PWA) almost exclusively after left-hemisphere brain damage (plus 24 residual symptoms 8 without aphasia) 88 control individuals. st...

Aphasia frequently leads to long-term consequences in language and communication. This paper presents an overview of current methods aphasia treatment, as well empirical data on their effectiveness limitations. We surveyed literature by accessing electronic databases Serbian libraries using specialized search engines the internet. A review papers confirmed existence numerous treatment today, wh...

Oral Reading for Language in Aphasia (ORLA) is a treatment technique in which the person with aphasia repeatedly reads aloud sentences and paragraphs, first in unison with the clinician, and then independently. Based on neuropsychological models of reading, ORLA was developed to improve reading comprehension in individuals with aphasia by providing practice in the phonological and semantic read...

The neurochemistry of language and the neuropharmacology of aphasia are two domains of cognitive neuroscience still in their infancy. In this article we review what is known about these two domains, especially with regard to treating aphasia with drugs. Selected neurotransmitters can improve language function in certain patients with aphasia. We discuss which neurotransmitters work for which la...

BACKGROUND Aphasia is one of the most disabling cognitive deficits affecting >2 million people in the USA. The neuroimaging characteristics of chronic aphasic patients (>6 months post onset) remain largely unknown. OBJECTIVE The objective of this study was to investigate the regional signal changes of spontaneous neuronal activity of brain and the inter-regional connectivity in chronic aphasi...

Cortical reorganization in poststroke aphasia is not well understood. Few studies have investigated neural mechanisms underlying language recovery in severe aphasia patients, who are typically viewed as having a poor prognosis for language recovery. Although test-retest reliability is routinely demonstrated during collection of language data in single-subject aphasia research, this is rarely ex...

Purpose The purpose of this article is to review the behavioral treatments used in aphasia rehabilitation research that have been combined with transcranial direct current stimulation (tDCS). Although tDCS in aphasia treatment has shown promise, the results have not been conclusive, and their interpretation is further compounded by the heterogeneity of study characteristics. Because implementin...
