Filter by:Aphasia is a devastating acquired language impairment mainly caused by stroke, in which anomia is a quintessential clinical feature. If speech-language therapy (SLT) has been shown to be effective for persons with aphasia, the relative efficiency of one SLT strategy over another remains a matter of debate. The influential relationship between language, executive functions and aphasia rehabilitation outcomes has been addressed in a number of studies, but only few of them have studied the effect of adding an executive training to linguistic therapies.The aim of this study is to measure the efficiency of a protocol combining anomia therapy and executive training on naming skills and discourse in post-stroke aphasic persons at the chronic stage
The proposed study is a Stage I successive cohort trial intended to adapt Acceptance and Commitment Therapy (ACT) to meet the specific needs of stroke survivors with aphasia ("ACT for Aphasia"). It will do so by incorporating communication supports and compensatory speech-language treatment. The goal of developing this integrated treatment is to improve successful communication participation, psychosocial adjustment, and quality of life for stroke survivors with aphasia. In the first phase of the project, the investigators will create a treatment manual with input from a stakeholder advisory board consisting of caregivers and stroke survivors with aphasia. The investigators will then recruit an initial cohort of five stroke survivors with aphasia to undergo the initial version of the treatment based and provide feedback. This will aid revision of the manual, which the investigators will then evaluate using a second cohort of 16 stroke survivors with aphasia. The investigators predict that ACT for Aphasia will be acceptable and feasible based on measures of participant satisfaction and treatment adherence. The investigators will also measure pre- to post-treatment changes in psychological distress, functional disability, quality of life, and communication participation and functioning to establish preliminary effect size estimates for this intervention, in preparation for a subsequent Stage II efficacy trial.
Positive outcomes have been shown following intensive treatment of speech and/or language impairment post stroke, but how to design intensive treatment programs to achieve optimal recovery and neuroplasticity changes needs to be further researched. The purpose of the MIRAA (Multimodal Intensive Rehabilitation of Aphasia and Apraxia of Speech) project is to study feasibility of intensive intervention for acquired aphasia and apraxia of speech (AOS) after stroke in the regular Swedish health-care according to the updated national guidelines from the Swedish National Board of Health and Welfare.
The primary objective of the study is to evaluate the feasibility of eliciting continuous narrative speech in different neurodegenerative and psychiatric indications, using remote, self-administered speech tasks, as measured by the average length of speech elicitation for each speech task during the first week of self-assessment. Secondary objectives include (1) evaluating the reliability of speech tasks in the remote self-administered setting, as measured by the intra- and inter-subject variance; (2) accessing the adherence of speech tasks in this setting, as measured by the subject average fraction of days during the first week, where at least one task response is submitted; (3) evaluating the feasibility of using speech tasks in the setting of a telemedicine videoconference, as measured by the average length of speech elicited in each group; (4) evaluate whether a set of acoustic and linguistic patterns can detect each indication, compare to either a control group or all other indications, as measured by the area under the receiver operating characteristic curve (AUC), sensitivity, specificity and Cohen's kappa of the relevant binary classifier; (5) evaluating how the performance of such algorithms can be impacted by speaker and environment covariates, as measured by the Kendall rank correlation coefficient of the AUC of each classifier and each of age group, gender and speech-to-reverberation modulation energy ratio.
Many stroke survivors experience aphasia, a loss or impairment of language affecting the production or understanding of speech. One common type of aphasia is known as non-fluent aphasia. Patients with non-fluent aphasia have difficulty formulating grammatical sentences, often producing short word fragments despite having a good understanding of what others are trying to communicate to them. Speech language pathologists (SLPs) play a central role rehabilitating persons with aphasia and administer therapy in an attempt to improve communication skills. Despite standard therapy, approximately 50% of individuals who experience aphasia acutely continue to have language deficits more than 6 months post-stroke. In most people, Broca's area is dominant in the left side of the brain. Following a left-sided stroke, the right-sided homologue of Broca's area (the pars triangularis), may adopt language function. Unfortunately, reorganizing language to the right side of the brain seems to be less effective than restoring function to the left hemisphere. Repetitive transcranial magnetic stimulation (rTMS), a form of non-invasive brain stimulation, can be used to suppress activity of specific regions in the right side of the brain to promote recovery of function in the perilesional area. Despite preliminary success in existing studies using rTMS in post-stroke aphasia, there is much work to be done to better understand the mechanisms underlying recovery. Responses to rTMS have been positive, yet heterogenous, which may be related to timing of treatments following stroke.
Stroke often causes substantial problems in speaking or understanding speech. Treatments for these problems are currently very limited. Limited studies to date suggest that repetitive Transcranial Magnetic Stimulation (TMS) to the side of the brain opposite to the side on which the stroke occurred may improve language function. The investigators are testing this hypothesis by giving daily 20 minute sessions of repeated TMS to the right (unaffected) side of the brain; the investigators test language function with a variety of tests both before and after the treatment with TMS and subjects are required to undergo functional MRI scans before and after treatment. TMS is a procedure in which a coil is placed next to the head of the subject and an electrical current passes through the coil causing a magnetic field that, in turn, causes a small electric current in the portion of the brain underneath the coil.
The purpose of this research is to better understand how dementia affects activity in different parts of the brain.

Aphasia is a disorder of language processing caused by a lesion in particular brain regions. Treatment aims at improving or restoring impaired function or at compensating for deficits. More recently, computer technology has been integrated into treatment options. In this study, a detailed and comprehensive computerized software program for aphasia rehabilitation is designed for the treatment of Arabic speaking Egyptian aphasic patients. Aim of the study: design a computerized software program for the rehabilitation of Arabic speaking Egyptian aphasic patients.
