Filter by:Despite evidence showing that speech and language intervention may improve language and communication abilities in people with acquired language disorders (aphasia), there is still need for evidence for which types of therapy are effective. Further, to improve accessibility of care, there is increasing need for evidence of intervention effects when therapy is provided online, via telerehabilitation. Therefore, the project aims at evaluating the effects of telerehabilitation with a specific speech-language therapy intervention for improving word-finding in individuals with aphasia due to stroke. The intervention Verb Network Strengthening Treatment (VNeST) trains word finding at sentence level, and the treatment effect is expected to generalize to the production of connected speech.
Aphasia is an acquired deficit following acute damage to the central nervous system that involves the difficulty or impossibility of understanding and formulating language. A typical disorder of non-fluent forms of aphasia is anomia. Anomia refers to the difficulty in finding words, in particular when trying to name objects and actions. According to the Embodied Cognition approach (EC), language is tightly connected to the motor system. In this view, language rehabilitation programs should stimulate language through the activation of the motor system. In this approach, since anomic deficits are often due to a weak link between the meaning of the word and its lemma, the Hebbs' principles of coincident and correlated learning can be exploited, i.e., by intensifying the synchronous activation of lexicon and semantics and connecting them with the motor counterpart. In this study, the investigators present an innovative training, based on the EC framework, in which they will make use of new technologies for anomia rehabilitation in post-stroke patients. Specifically, the researchers will use immersive 360° videos representing everyday actions displayed from the first-person point of view, experienced through a head-mounted display. The training will be administered 3 times a week for 4 weeks. The control group will watch standard videos representing the same actions recorded from the third-person perspective. Naming abilities will be tested before and after the training together with other cognitive and psychological measures. The investigators expect that the group who will undergo the 360° video-based training will show greater improvement of performance compared to the control group.
Out of 30,000 new cases per year in France, 30% of epileptic patients are drug-resistant. Neurosurgery, which consists in resecting the epileptogenic zone, is the only chance of cure. In the case of temporal epilepsy of the language-dominant hemisphere (TLE), this procedure presents a high risk of increasing cognitive difficulties and may even be contraindicated for this reason alone. The difficulties found are impairments in lexical access (anomia) and verbal memory and affect more than 60% of patients . Preoperative cognitive rehabilitation could influence brain plasticity mechanisms but there are currently no recommendations on this topic. In this context, the investigators have developed a speech rehabilitation procedure specific to the needs of ELTPR patients. They rely on cognitive hypotheses explaining the disorders but also on models of rehabilitation-induced neural plasticity likely to improve cognitive reserve before surgery. The investigators hypothesize that preoperative cognitive language rehabilitation in ELTPR patients may decrease surgical risk and improve postoperative language prognosis. The primary objective is to demonstrate the protective efficacy of preoperative speech rehabilitation on language performance postoperatively.
The main aim of the study is to investigate the effect of a novel, speeded anomia therapy (Conroy et al., 2018) in a large population of patients with chronic post-stroke aphasia. The treatment will be delivered via a web application (QuickWord).
The purpose of the study is to test whether low level electric stimulation, called transcranial Direct Current Stimulation (tDCS), on the part of the brain (i.e., pre-supplementary motor area) thought to aid in memory will improve verbal retrieval in civilian (non-military, non-veteran) participants with histories of traumatic brain injuries. The primary outcome measures are neuropsychological assessments of verbal retrieval, and the secondary measures are neuropsychological assessments of other cognitive abilities and electroencephalography (EEG) measures. Additionally, the study will examine the degree to which baseline assessments of cognition, concussion history, structural brain imaging, and EEG predict responses to treatment over time, both on assessments administered within the intervention period and at follow-up.
Although there is evidence that speech-language therapy may improve speech in language disorders following left hemisphere stroke there is still a lack of evidence for which types of therapy are effective. Furthermore, in Sweden, as well as in several other countries, access to speech-language therapy is limited. The purpose of this clinical trial is to compare outcome from Verb Network Strengthening Treatment (VNeST) provided as In-Clinic therapy (I-CT) or as synchronous telepractice therapy (TP-T).
Aims and background Everyone forgets the names of people they should know at times. Having dementia makes this problem worse. People with dementia have told expressed they forget the names of people they care about and this can be upsetting and embarrassing. However, evidence shows that if people get enough practice, they can re-learn these names. The investigators, along with people with dementia and their carers, have created a fun therapy for people to get lots of practice so they can remember the names of people that are important to them. The main aim of the study is: To prove that Gotcha! therapy can help people with dementia to improve their ability to remember names. Another aim is: To find out if using the therapy is related to any changes in the brains of people with dementia. Design and methods Participants are provided with a computer tablet to practise at home. Participants are required to think of 6-10 familiar people (family and friends) whose names they forget and want to remember better. Participants also need to practise every day for about 30 minutes over a 6 week period so they get a large amount of therapy. Participants will have 7 testing appointments over 12 months. At three of these appointments participants will need to have a brain scan. These scans are carried out by trained University College London professionals and will take no longer than 30 minutes each. For the appointments where participants do not need to have a brain scan home testing can be arranged. The investigators organise and pay for all journeys to and from University College London. Participants Participants can get involved in our research if they: - Have ever experiences seeing a familiar person but can't remember their name - Have a diagnosis of dementia (Alzheimer's disease or mixed dementia). - Want to be part of an important and exciting research journey. Unfortunately a diagnosis of other any other types of dementia not mentioned above is not suitable for this study Patient and Public involvement The investigators have engaged with people from the Alzheimer's Society and local dementia carers groups, run many focus groups and interviewed people with dementia and their carers to co-design the therapy. At the end of our research participants are invited to University College London to learn about the results of the study.
A debilitating and common symptom in Gulf War Illnesses (GWI) is the inability to retrieve words. This affects one's conversations, ability to fluidly exchange information verbally and retrieve information from memory. The investigators have discovered 3 brain regions - the PreSupplementary Motor Area (preSMA), caudate nucleus, and the thalamus - that are essential for word retrieval. They have also detected abnormal EEG signals related to these regions in GWI patients who have problems retrieving words. The investigators have used their model of verbal retrieval to design a noninvasive, nonpharmacological treatment that uses High Definition transcranial Direct Current Stimulation (HD tDCS). Using HD tDCS, they deliver small amounts of electric current to areas of the head to stimulate specific brain regions. The objective is to determine if delivery of HD tDCS over the preSMA will improve performance in GWI veterans with a verbal retrieval deficit. The investigators will administer pre-treatment tests of verbal retrieval measures while recording brain electrical activity. They will then administer 10 sessions of HD tDCS over the preSMA (20 minutes a session) in half the veterans. The other half will go through the same procedures, except the current will not be turned on (called the sham condition). The investigators will then compare performance between the "active" and sham group and assess if the treatment had a significant effect on performing verbal retrieval tasks and if there is a change in the ERP markers to account for how the treatment worked. If the treatment is found to be effective it will be offered to those in the sham group at the study's end. The investigators predict this treatment regimen will lead to positive effects on a person's daily functions, especially improved conversational abilities, with few, if any, side effects. They hope to outline the standard procedures for physicians to perform the treatment by creating a manual on how to apply the treatment in a clinical setting so that it will be quickly available to use in multiple sites if the proposed study demonstrates that it is efficacious. This treatment can be made widely available for Warrior Transition Units, military clinics, and VA medical centers. In addition, if successful, this could potentially lead to development of other targets of stimulation to improve other cognitive deficits in GWI, and help alleviate verbal fluency deficits associated with other disorders.
