The Effects of a Multimodal Approach for the Treatment of Primary Progressive Aphasia

Primary Progressive Aphasia

Primary Progressive Aphasia (PPA) is an untreatable neurodegenerative disorder that disrupts language functions. Available therapies are mainly symptomatic and recently attention has been gained by new techniques that allow for noninvasive brain stimulation such as transcranial direct current stimulation (tDCS). The primary objective of this study is to evaluate whether the application of Active tDCS (anode over the left dorsolateral prefrontal cortex- DLPFC with the cathode over the right supraorbital region) to the scalp during individualized language training, would improve naming abilities in the agrammatic variant of PPA (avPPA) more than use of one methodology alone. The effect of treatment on the clinical symptoms will be related to changes in brain activity (Magnetic Resonance Imaging, MRI and Functional near-infrared spectroscopy fNIRS) and in biological markers, using a multimodal approach. Finally, we will assess the long-term effects of this approach.

Treatment for Speech and Language in Primary Progressive Aphasia

Primary Progressive AphasiaSemantic Dementia7 more

Primary progressive aphasia (PPA) is a progressive neurological disorder that causes a gradual decline in communication ability as a result of selective neurodegeneration of speech and language networks in the brain. PPA is a devastating condition affecting adults as young as their 40's or 50's, depriving them of the ability to communicate and function in society. There has been significant progress in discovering the neurobiological mechanisms that underlie PPA and in identifying its clinical phenotypes. With these advances, we are poised to investigate behavioral treatments that are grounded in modern cognitive and neuroanatomical concepts. Research documenting the efficacy of speech-language treatment for PPA is emerging, but limited. Systematic research is needed to establish best clinical practices in this unique patient population for whom pharmacological treatment remains elusive. The long-term objectives of this project are to provide evidence-based treatment methods addressing the speech and language deficits in PPA and to determine the neural predictors of responsiveness to intervention. The study has three main goals that build on the findings of our previous work: 1) to examine the utility of treatments designed to facilitate significant, generalized and lasting improvement of speech-language function in PPA, 2) to determine whether treatment alters the trajectory of decline in PPA by comparing performance on primary outcome measures in treated versus untreated participants after a one-year interval, and 3) to identify imaging predictors (gray matter, white matter, and functional connectivity measures) of responsiveness to behavioral intervention in individuals with PPA. In order to accomplish these aims, we will enroll 60 individuals with PPA, who will undergo a comprehensive multidisciplinary evaluation and neuroimaging. Subsequently, participants will be enrolled in treatment designed to promote lasting and generalized improvement of communicative function in core speech-language domains. Participants will be followed for up to one-year post-treatment in order to determine long-term effects of rehabilitation, and their performance will be compared with a historical cohort of untreated PPA patients. This ambitious study and the necessary recruitment will be possible due to an ongoing collaboration with the UCSF Memory and Aging Center, a leading institution in the field of PPA research. The study will broaden the evidence base supporting the efficacy of speech-language intervention in PPA and will provide novel evidence regarding neural predictors of treatment outcomes, with the potential to inform clinical decision-making and improve clinical care for individuals with this debilitating disorder.

Enhancing Language Function in Primary Progressive Aphasia

Primary Progressive Aphasia

This study's goal is to use non-invasive brain stimulation (NBS) techniques to treat language impairment associated with Primary Progressive Aphasia (PPA). The purpose of this study is to combine behavioral language intervention with individualized noninvasive brain stimulation techniques, called transcranial direct current stimulation (tDCS) to help the brain reorganize around damage and improve language functions.

A Study to Evaluate the Safety and Effect of AVB-101, a Gene Therapy Product, in Subjects With a...

Frontotemporal DementiaFTD3 more

The goal of this clinical study is to learn about an investigational gene therapy product called AVB-101, which is designed to treat a disease called Frontotemporal Dementia with Progranulin Mutations (FTD-GRN). FTD-GRN is an early-onset form of dementia, a progressive brain disorder that affects behavior, language and movement. These symptoms result from below normal levels of a protein called progranulin (PGRN) in the brain, which leads to the death of nerve cells (neurons), affecting the brain's ability to function. The main questions that the study aims to answer are: Is a one-time treatment with AVB-101 safe for patients with FTD-GRN? Does a one-time treatment with AVB-101 restore PGRN levels to at least normal levels? Could AVB-101 work as a treatment to slow down or stop progression of FTD-GRN? In this study there is no placebo (a dummy pill or treatment used for comparison purposes), so all participants will receive a one-time treatment of AVB-101 delivered directly to the brain, with follow-up assessments for 5 years.

Enhancing Language Function in Aphasia

AphasiaAcquired4 more

Aphasia is an acquired impairment of language, that commonly results from damage to language areas in the brain (typically the left side of the brain). This impairment is seen in many aspects of language, including understanding, speaking, reading and writing. It is estimated that about 2 million individuals are currently living with aphasia in the United States. Further, about 200,000 Americans acquire aphasia every year (National Aphasia Association, 2020). Aphasia poses significant impact on the affected individuals and their families. Behavioral treatments that target language deficits have been shown to enhance overall communication skills and life satisfaction among individuals with aphasia. Although there is evidence that suggests that treatment is efficacious for individuals with aphasia, the extent of improvement long-term coupled with the neural patterns among those individuals are largely unknown. The current study aims to investigate the efficacy of language-based treatment and its corresponding neural patterns.

tDCS Intervention in Primary Progressive Aphasia

Primary Progressive AphasiaMCI1 more

Primary progressive aphasia (PPA) is a neurodegenerative disease that affects first and foremost language abilities. Mild cognitive impairment (MCI) is slowly progressive decline in a single domain of cognition (e.g. language) not attributable to motor or sensory loss, without impediment of social or occupational function. MCI can be an early sign of neurodegenerative disease, or can be due to normal aging. When language is the prominent affected domain in MCI, the person may later meet criteria for PPA or may progress to the clinical syndrome of Alzheimer's dementia. Spelling, naming, and working memory (e.g. repetition) are among the language abilities affected early in the course of PPA or language-centered MCI, and different variants have distinct deficits in these domains. This research project investigates the behavioral and neuromodulatory effects of high definition transcranial direct current stimulation (HD-tDCS) during language therapy in PPA participants over time. Anodal HD-tDCS targeting the left inferior frontal gyrus (IFG) administered in combination with language therapy is expected to be more beneficial when compared to language therapy alone. It will 1) improve language performance or decrease rate of decline, 2) have better-sustained effects at 2 weeks and 2 months post-treatment, and 3) produce generalization to untrained language items and some other cognitive functions. Resting-state fMRI, diffusion tensor imaging (DTI), and volumetric data are also collected to investigate changes in functional brain connectivity associated with HD-tDCS in individuals with PPA. A better understanding of the therapeutic and neuromodulatory mechanisms of HD-tDCS as an adjunct to language therapy in PPA may have a significant impact on the development of effective therapies for PPA and MCI, and may offer insight into ways of impeding neurodegeneration that may improve patients' quality of life, as well as extend their ability to work and manage their affairs.
