Aphasia Recovery

Background and Objectives: Aphasia is common consequence of stroke. Most people with aphasia in the acute phase show some degree of spontaneous recovery, most of which occurs during the first two to three months. Neuro-linguistic mechanisms of recovery in aphasia remain a lot unknown still, but considerably depends to the amount of change plasticity in brain of patients after stroke. The aim of this article is review of the role of Neuroplasticity types in aphasia recovery and its influencing factors: a systematic review of literatureMethods: This study is a review of all articles listed in PubMed database from January 1990 to September, 2016 that were identified using the keywords Neuroplasticity and aphasia (in titles) and language.Results: Three types of changes in the activity of the nervous system after a stroke, is closely linked with aphasia recovery: 1. Reactivation of damaged areas of the left hemisphere or activities it`s surrounding in language tasks 2. Acquisition or manifest of the ability to process language in the nondominant right Hemisphere 3. The wrong activity of nondominant right hemisphere that can prevent language improvement.Discussion and Conclusion: Most of studies have shown involvement of surrounding areas in the left hemisphere lesion in language improvement, others reported employment of the right hemisphere regions and some others have known useful the involvement of both hemispheres in language improvement. It is difficult, aphasia improvement prediction due to the interaction of various factors. The most promising results aphasia treatment for the reorganization of the brain, caused by speech therapy that lead to quick improvements considerably.

Aphasia Recovery

Previous data obtained especially from rTMS studies indicate that right hemisphere recruitment has a limiting effect on recovery of poststroke aphasia in right handed patients by inhibiting the activation of intact perilesional areas in left hemisphere and preventing them from regaining function. New researches bring new arguments to support the positive influence of right hemisphere on restoration of language and communication. In this paper we try to review the latest evidences regarding the contribution of the right hemisphere to post-stroke aphasia recovery.

Healthy Participants

Studies investigating human brain response to emotional stimuli—particularly high-arousing versus neutral stimuli—have obtained inconsistent results. The present study was the first to combine magnetoencephalography (MEG) with the bootstrapping method to examine the whole brain and identify the cortical regions involved in this differential response. Seventeen healthy participants (11 females, aged 19 to 33 years; mean age, 26.9 years) were presented with high-arousing emotional (pleasant and unpleasant) and neutral pictures, and their brain responses were measured using MEG. When random resampling bootstrapping was performed for each participant, the greatest differences between high-arousing emotional and neutral stimuli during M300 (270–320 ms) were found to occur in the right temporo-parietal region. This finding was observed in response to both pleasant and unpleasant stimuli. The results, which may be more robust than previous studies because of bootstrapping and examination of the whole brain, reinforce the essential role of the right hemisphere in emotion processing.

ABSTRACT The role of the right cerebral hemisphere (RH) associated with semantic priming effects (SPEs) must be better understood, since the consequences of RH damage on SPE are not yet well established. Objective: The aim of this article was to investigate studies analyzing SPEs in patients affected by stroke in the RH through a systematic review, verifying whether there are deficits in SPEs, and whether performance varies depending on the type of semantic processing evaluated or stimulus in the task. Methods: A search was conducted on the LILACS, PUBMED and PSYCINFO databases. Results: Out of the initial 27 studies identified, 11 remained in the review. Difficulties in SPEs were shown in five studies. Performance does not seem to vary depending on the type of processing, but on the type of stimulus used. Conclusion: This ability should be evaluated in individuals that have suffered a stroke in the RH in order to provide treatments that will contribute to their recovery.
