The efficacy of the intervention also will be examined on key outcomes.
The causes of neurodegenerative dementias such as Frontotemporal Dementia, Lewy Body Disease and Alzheimer's disease are still largely unknown. While the contribution of some genetic mutations and polymorphisms is associated with autosomal dominant patterns of inheritance of these dementias, in many cases, the specific causative mutation in these families is not yet identified. Further, in many patients, polygenic risk is thought to give rise to pathophysiologic changes, but which specific genes affect risk are largely yet unknown. By examining genotypes in patients that present to our Cognitive Neurology and Alzheimer's Research Clinic with suspected or confirmed neurodegenerative dementia, or have a history of a familial dementia, we aim to help identify and characterize genetic mutations or polymorphisms that give rise to neurodegenerative diseases.
Primary progressive aphasia (PPA) is a disorder characterized by gradual decline in speech-language ability caused by underlying neurodegenerative disease. PPA is a devastating condition that can affect adults as young as their 50's, depriving them of the ability to communicate and function in society. Along with Alzheimer's Disease and other Alzheimer's Disease Related Dementias (AD/ADRD), PPA is now identified earlier and with greater precision. Increasingly, patients and families seek options for behavioral and neuromodulatory treatments to address PPA's devastating effects on communication, prolong speech-language skills, and maximize quality of life. Studies have documented the robust benefits of speech-language telerehabilitation methods for persons with PPA, with in-home treatment resulting in immediate and long-term benefits. This investigation aims to further enhance the potency of these treatment approaches by pairing them with tailored neuromodulatory intervention that targets critical brain networks supporting treatment in each clinical subtype of PPA. The study will evaluate the feasibility and preliminary benefit of home-based transcranial direct current stimulation (tDCS) combined with evidence-based speech-language telerehabilitation methods. tDCS will be delivered to patients in their own homes and site of stimulation will be tailored for each clinical subtype of PPA. This project has the potential to enhance clinical management and rehabilitation for individuals with PPA by establishing the benefit of behavioral and neuromodulatory treatment that is neurobiologically-motivated and accessible for patients and families.
Assistive Technologies (ATs) can help people living with dementia (PwD) maintain their everyday activity. Still, there is a gap between potential and supply. Involving future users can close the gap. But the value of participation from PwD is unclear. The study examined smartwatch interactions from people with dementia or with mild cognitive impairment. Participants received "regularly" (n=20) or "intensively" (n=20) intrusive audio-visual prompts on a customized smartwatch to perform everyday tasks. Participants' reactions were observed via cameras. Users' feedback was captured with questionnaires.
Frontotemporal degeneration (FTD) is a non-Alzheimer's dementia that is the 2nd most common cause of dementia in the United States. FTD may present with focal language symptoms that are clinically described as primary progressive aphasia (PPA). There are two types of PPA associated with FTD-semantic variant primary progressive aphasia (SV-PPA) and nonfluent/agrammatic variant primary progressive aphasia (NFV-PPA). Both diseases are progressive neurodegenerative disease processes that compromise dominant hemisphere large scale brain network function, ultimately resulting in mutism. There are currently no FDA-approved treatments for PPA and management is mostly supportive. In combination with resting state functional MRI (rs-fMRI), transcranial magnetic stimulation (TMS) with intermittent theta burst stimulation (iTBS) offers a non-invasive alternative to pharmacotherapy in persons with PPA. In our prior studies of Alzheimer's disease (AD) and Lewy body Dementia (LBD) subjects, investigators have determined that the anterior temporal pole (area TGd and TGv) is an area that is commonly dysfunctional in dementia. The investigators have already embarked upon an fMRI guided study of iTBS in early stage Alzheimer's disease where subjects received a series of 5 treatments to distinct brain regions inclusive of area TGd. The investigators propose a case study of 3 PPA studies where rs-fMRI is applied to the large-scale language networks.
There are very few treatments for neurodegenerative disorders, and the efficacy of these treatments is generally modest. Recent studies have shown a short-term positive effect of non-invasive neuromodulation techniques such as transcranial magnetic stimulation (TMS) in primary progressive aphasia (PPA). PPA is a clinical syndrome associated with Alzheimer's disease and Frontotemporal degeneration. The aim of this study is to compare the effect of TMS and language therapy versus language therapy and sham TMS in patients with PPA during 6 months. A prospective, randomized, controlled, double-blind and parallel clinical trial will be conducted. The changes in brain metabolism using FDG-PET, language, neuropsychiatric symptoms, and daily-living activities will be assessed. Connectivity changes using electroencephalography will also be examined. In addition, a subgroup of patients will be assessed with multimodal MRI (structural and functional), and blood biomarkers. As a result of this project, valuable information about the long-term efficacy of non-invasive brain stimulation in PPA will be obtained, as well as the mechanisms of the therapy and clinical and neuroimaging factors associated with therapy response.
This observational study will use new smartwatch technology to continuously and remotely monitor the health of ALS patients and healthy controls over time. This information will be used to develop digital biomarkers for ALS.
Memory and social interaction are intimately linked. On the one hand, social interaction is a privileged context for learning, and on the other hand, appropriate social interactions involve remembering the partners encountered and previous exchanges. People with Alzheimer's disease classic syndrome variant (AD) have a major impairment of episodic memory, while people with the semantic variant of primary progressive aphasia (SPPA) are characterized by semantic disorders in the foreground, associated with changes in their social behavior with a tendency to egocentricity. In both cases, patients frequently have reduced social interactions. Although social interaction situations seem to constitute a privileged learning context, their effectiveness for patients with cognitive disorders must be evaluated and the conditions under which they are effective must be established. The main objective of this study is to determine whether social interaction constitutes a beneficial context for learning new information and whether the presence of social behavior disorders alters this benefit. More broadly, the goal is to better understand the mechanisms underlying the possible beneficial effect of learning in social contexts and to clarify the links between memory performance in different social contexts, cognitive disorders, social behavioral changes and personality traits. Finally, a description will be made of the brain substrates associated with memory performance obtained during learning in social contexts in order to investigate their particularities. Thirty couples each including a person with AD, 16 couples each including a person with SPPA and 46 couples of persons without cognitive complaints (HC), one of which will be matched in gender and age to one of the patients, will be included in the study. Participants will perform image location learning in a grid, in three social contexts in which both members of the couple are involved: 1) simple presence of others, 2) by observation and 3) in collaboration. A psychometric assessment including social cognition and classical tests assessing memory, and questionnaires concerning global executive functioning, social behavior and personality will be offered to all participants. Patients in the AD and SPPA groups and the matched individual in the HC group will undergo anatomical and functional brain magnetic resonance imaging (MRI).
This research is being done to develop a unique matching process for caregivers of persons living with dementia, such as Alzheimer's disease, Lewy body dementia, frontotemporal degeneration, or other dementia syndromes. Dementia caregivers often assume greater caregiving burden than do non-dementia caregivers, and the caregiving duration tends to be longer. Many caregivers do not have the adequate support they need. Peer-to-peer support has been shown to improve quality of life, more engagement with services, improve caregiver health, and reduce hospitalizations in the person they are caring for. This study will help determine whether caregivers of persons with dementia would find a technology-based caregiver matching program valuable for the purpose of emotional support.
