Filter by:This study will evaluate evidence-based treatments for adults with mild Primary Progressive Aphasia (PPA). The aim of the study is to help identify efficacious communication and quality of life interventions for those with PPA and their care-partners. Participants with a diagnosis of PPA and their actively-engaged care partners will be involved in the study for 12 months. Each participant will receive a iPad equipped with the necessary applications and features for the study. Participants will complete evaluations, speech therapy sessions with a speech and language therapist, and sessions with a licensed social worker or related clinician. They will have access to Communication Bridge, a personalized web application to practice home exercises that reinforce treatment strategies. There are no costs to participate in this study.
The purpose of this study is to establish the feasibility of a program of remotely supervised transcranial direct current stimulation (RS-tDCS) paired with language skills practice for people living with the semantic or logopenic variants of primary progressive aphasia (PPA). There are currently no established standard-of-care treatments for PPA. This study will evaluate whether RS-tDCS combined with language skills practice is a feasible study design for individuals with PPA.
The diagnosis of neurocognitive disorders such as early Alzheimer's disease (AD) or primary progressive aphasia (PPA) is particularly difficult and constantly evolving, often leading to diagnostic erraticity. However, several studies have shown that graphic parameters are affected in people with moderate to severe Alzheimer's disease. The use of new technologies in the study and analysis of the abilities of people with neurodegenerative diseases is increasingly recommended. The use of a digital tablet with a stylus makes it possible to objectivize the kinematic parameters of writing (pressure, inclination, speed, jerk, time of writing task) and thus would allow a low-cost diffusion of this technology in particular by including it in already existing screening batteries. The overall objective of the project is to characterize and compare the graphical markers of a writing task, either language-based (writing words, non-words, sentences) or non-language-based (drawing shapes), in patients with PPA, early-stage Alzheimer's disease (i.e., at the stage of minor neurocognitive disorders and major neurocognitive disorders at the beginning of the disease), and in people with no cognitive disorders.
This is a feasibility study on the effects of an online-based training and education programme for carers of people with posterior cortical atrophy (PCA), primary progressive aphasia (PPA) and behavioural-variant frontotemporal dementia (bvFTD).
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.
The purpose of this research is to better understand how dementia affects activity in different parts of the brain.

Primary Progressive Aphasia (PPA) is a neurodegenerative disease in which language function is gradually and progressively impaired. Patients will eventually be disabled in communication and have cognition deficits, which put a heavy burden not only on their families but also on the whole society. However, no effective treatment for PPA has been explored so far. The current clinical randomized trial is to study the safety and efficacy of repetitive Transcranial Magnetic Stimulation (rTMS) for the treatment of PPA. Also, multi-modality of neuroimaging techniques, such as functional MRI and PET will be used to investigate brain network changing in this procedure.
The primary goal of this pilot project is to adapt an evidence-informed on-line psychoeducation program (Tele-Savvy) to address the unique challenges facing informal caregivers of those living with PPA and geared toward achieving caregiver mastery in this population.
The purpose of this study is to assess the effects of non-invasive brain stimulation on memory and language ability in patients with two phenotypic variations of underlying Alzheimer disease pathology: amnestic mild cognitive impairment (aMCI) and logopenic variant of primary progressive aphasia (lvPPA). This study will use repetitive Transcranial Magnetic Stimulation (rTMS) to stimulate nodes of networks that are thought to be affected in these two conditions. Specifically, a node of the Default Mode Network (DMN)-the angular gyrus (AG)-will be stimulated in aMCI patients; and a node of the language network-the posterior inferior frontal gyrus (pIFG) will be stimulated in patients with lvPPA. We will use functional connectivity MRI (fcMRI) to assess changes in functional network architecture following the stimulation. We will also assess putative cognitive improvements resulting from the stimulation by in-depth language testing in lvPPA patients and in-depth memory testing in aMCI patients.
