Filter by:TMS is a non-invasive brain stimulation technique, which can be used to change the activity of a person's brain cells without needles or surgery. In this study, the invesigators are interested in the brain's ability to adapt (also called "neuroplasticity") and regain language functioning after a stroke—specifically, they want to determine whether how a person's brain responds to TMS in the short term can be used to predict how well they will recover language abilities in the long term.
The purpose of this study is to investigate whether transcranial direct current stimulation (tDCS) of the prefrontal cortex (PFC) influences lexical access and language production. The experimental paradigm will assess the impact of prefrontal stimulation by tDCS versus sham tDCS (S-tDCS) over the PFC of patients with chronic post-stroke aphasia during three language production tasks and a nonverbal executive functions task.
Constraint-induced aphasia therapy (CIAT) has proven effective in stroke patients. It has remained unclear, however, whether intensity of therapy or constraint is the relevant factor. This study will give an answer to this question to improve speech and language therapy.
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.
Participants will receive either intensive phonology or semantic feature analysis treatment for 16 weeks to improve naming, reading, and writing in individuals with chronic post-stroke aphasia.
This study aims at contributing with scientific evidence to the field of aphasia telerehabilitation. In Norway today, there is an unmet need for language training in post stroke aphasia and not all patients are offered language training. Early start of aphasia rehabilitation and satisfying intensity do not seem to be standard clinical practice. Language training by telemedicine could improve this situation, and this study seeks to answer the question whether aphasia rehabilitation delivered by videoconference can improve language function in aphasia post stroke.
This is a neuroimaging study designed to learn more about amyloid and tau burden in the brain of patients with typical and atypical Alzheimer's Disease and how burden may change over a one year period.
This study is designed to learn more about overall tau burden in the brain of patients with Primary Progressive Aphasia (PPA) and Frontotemporal Dementia.
The study will invite 30 patients to join, and they will be arranged in the face to face group and telerehabilitation group randomly. In the telerehabilitation group, the investigators use the mobile device, which with the camera and speaker, for patients to practice the naming training at home, and assess the speech ability every 2-4weeks by speech therapist via telerehabilitation platform. Concise Chinese Aphasia Test (CCAT) and ASHA FACS conceptual framework Test will be used as the assessment tool for evaluation speech ability and functional ability. The investigators expect that patients can improve their speech ability, functional ability, and quality of life via telerehabilitation speech therapy. And the investigators can establish the standard telerehabilitation speech therapy protocol for aphasia therapy.
The goal of this study is to remediate word-finding problems in patients who have Primary Progressive Aphasia (PPA) or Alzheimer's Disease and to delay the further progression of word-finding impairment. The current approach is novel in that it contains a prophylaxis component in which the investigators attempt to strengthen neural connections that remain functional, making them more resistant to degradation as the disease progresses. While the study is specific in its targeting of word-finding problems, a successful outcome would bode well for other studies aimed at prevention or reversal of declining cognitive functions in dementia. One set of participants with PPA will receive practice with picture naming in two conditions: viewing the picture and repeating the name; and viewing the picture with its written name, plus reading and writing the name. Another set of participants with PPA or Alzheimer's Disease will be trained in two different conditions: learning about the word's semantic features (meaning); and learning about the word's lexical features (letters and sounds). Naming of pictures trained in each of these conditions will be compared, at three time intervals post-training, with naming of pictures tested before the study but never trained. It is predicted that the pairing of the picture with its written name, combined with the motor task of writing the name, will result in a greater ability to name the picture at a later date than simple practice viewing the picture and repeating the name. Furthermore, it is predicted that participants who have difficulty understanding concepts will be more likely to respond to semantic treatment, while participants who have difficulty connecting words with concepts will be more likely to respond to lexical treatment.
