Filter by:This study is examining the use of intensive melodic intonation therapy and video feedback as a means of aiding individuals with nonfluent aphasia and co-occurring motor speech impairments. Individuals with nonfluent aphasia have difficulty with language, particularly with word retrieval.
Aphasia is a language disorder, commonly resulting from stroke or other brain injury, that impacts a person's ability to communicate. This project is looking to improve upon current treatment methods for spoken naming in people with aphasia. People with aphasia frequently report being able to successfully say a word in their head, regardless of their ability to say the word out loud. For example, when presented with a picture of a house, they may report being able to think or hear "house" in their head, even if they can't name it out loud. This "little voice" inside one's head is known as inner speech (IS). Previous research suggests that some people with aphasia can re-learn to say words with successful IS (i.e., words they can already say in their heads) easier and faster than words with unsuccessful IS. This study will extend these findings by implementing a comparative treatment study in a larger group of participants with aphasia. The results will help to establish recommendations for speech-language pathologists in choosing treatment stimuli for anomia.
The primary objective of this research is to evaluate the effects of non-invasive brain stimulation and computerized cognitive training on executive functioning in individuals with Primary Progressive Aphasia (PPA), mild cognitive impairment (MCI), or dementia. In this study, investigators will use transcranial direct current stimulation (tDCS) to stimulate the left dorsolateral prefrontal cortex (DLPFC). Previous studies have demonstrated that tDCS over the DLPFC led to improvements in attention deficit caused by stroke, Parkinson's Disease, and major depression as well as language deficits caused by neurodegenerative conditions such as primary progressive aphasia or mild cognitive impairment. The investigators seek to expand on this literature by investigating how anodal tDCS paired with and without cognitive training will impact executive functioning in PPA with Frontotemporal Dementia or Alzheimer's Disease pathology and Mild Cognitive Impairment/Alzheimer's Disease (e.g. shifting, updating, monitoring, and manipulation).
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 speech and language difficulties in patients with primary progressive aphasia (PPA) and progressive apraxia of speech (PAOS). The primary outcome measures are neuropsychological assessments of speech and language functions, and the secondary measures are neuropsychological assessments of other cognitive abilities and electroencephalography (EEG) measures.
The investigators aim to learn more about symptoms suggestive of a neurodegenerative process.
This project aims to develop a clinically feasible version of a laboratory-developed assessment battery for language and verbal short-term memory difficulties in aphasia.
The purpose of this study is to determine if transcranial direct current stimulation (tDCS) in conjunction with intensive speech therapy will improve sentence production and word retrieval in individuals with chronic post stroke aphasia.
The aim of this research is to translate a theory of the cognitive relationship between verbal short--term memory (STM) and word processing impairments in aphasia to treatment approaches for language impairment in aphasia. It has been proposed that the co-occurrence of these impairments is due to a disruption of cognitive processes that support both abilities: maintenance of activated semantic and phonological representations of words, hereafter the 'activation--maintenance hypothesis'. This hypothesis will be tested in the context of a treatment approach that aims to improve word processing and verbal STM abilities. The grant supporting this work has ended. therefore, participants are entered into the study by invitation only.
