Intranasal Oxytocin for Frontotemporal Dementia

Frontotemporal Dementia

The purpose of this study is to assess the safety, tolerability and effects on behaviour of Syntocinon given intranasally (by a spray into the nostrils) compared to placebo (an inactive saline substance that contains no medication) in participants with frontotemporal dementia/Pick's disease. This study will take place in approximately 15 centres across Canada and the United States. Approximately 112 patients in total will be enrolled in this study. In the first phase we will examine which of three different dosing schedules of oxytocin may be more effective. In the second phase of the study, patients entering the study will be randomized to the oxytocin dosing schedule that appeared most effective in the first phase.

Speech-Language Treatment With Remotely Supervised Transcranial Direct Current Stimulation in Primary...

Primary Progressive Aphasia

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.

Study of IV VTS-270 for Infantile Liver Disease Associated With Niemann-Pick Disease, Type C

Niemann-Pick DiseaseType C

Niemann-Pick disease, type C (NPC) is a lethal, autosomal recessive, lysosomal storage disorder characterized by neurodegeneration in early childhood and death in adolescence. NPC results from mutation of either the Niemann-Pick C1 disease (NPC1) (~95% of cases) or NPC2 genes. NPC is characterized by the endolysosomal storage of unesterified cholesterol and lipids in both the central nervous system and peripheral tissues such as the liver. Individuals with NPC demonstrate progressive central nervous system decline including inability to coordinate balance, gait, extremity and eye movements. Acute liver disease in the newborn/infant period is frequently observed, but subsequently resolves. However, chronic, sub-clinical liver disease persists. Intrathecal 2-Hydroxypropyl-β-Cyclodextrin (HP-β-CD, VTS-270) has proven effective in reducing the signs and prolonging life in animal models and Phase 1/2a data support efficacy in NPC1 patients. VTS-270 also has been shown to be effective in treating liver disease in the NPC1 cat. This Phase 1/2a, open-label, multiple ascending dose trial will evaluate whether VTS-270 administered intravenously is effective in treating acute liver disease in NPC1 infants.

Molecular Neuroimaging of Neuroinflammation in Neurodegenerative Dementias

Frontotemporal Dementia

Neuroinflammation is increasingly implicated as a potential critical pathogenic mechanism in a variety of neurologic and psychiatric disorders. This study will use hybrid PET/MRI imaging to evaluate neuroinflammation and its relationship to cerebral perfusion in frontotemporal dementia (FTD). Patients with FTD will be recruited from the Cognitive Neurology and Aging Brain clinics at Parkwood Institute and will undergo neurocognitive assessment and MRI/PET using the PET ligand FEPPA which binds to activated microglia, a marker of neuroinflammation. Correlations will be conducted to determine whether abnormal neuroinflammation is present in Frontotemporal dementia and whether differential patterns of neuroinflammation are present in different FTD clinical and molecular subtypes, and to determine the relationship between neuroinflammation, cerebral perfusion using arterial spin labeling MRI imaging techniques, and indices of brain structure including volumetric and white matter analysis.

The Influence of Vascular Burden, Amyloid Plaque and Tau Protein in Patients With Vascular Cognitive...

Vascular Cognitive ImpairmentAlzheimer's Disease1 more

Background and objects Amyloid plaques and tau protein are the landmarks of neurodegeneration in Alzheimer's disease (AD). On the other hand, it is reported that cerebral ischemia may induce amyloid plaques and tau protein accumulation. However, it was difficult to in vivo disentangle the complex and dynamic interactions between AD pathophysiology and cerebral vascular injury during the post-stroke cognitive impairment development in the past. With the advent of novel radiotracers specific to cerebral amyloid plaques and tau protein, we aim to conduct a prospective multimodal neuroimaging cohort study to investigate the contribution of vascular injury, amyloid plaque and tau protein to cognitive impairment. Subjects and methods The prospective project plans to recruit patients with vascular cognitive impairment (VCI) (Group A, n=80), Alzheimer's disease/mild cognitive impairment (MCI) (Group B, n = 120), fronto-temporal dementia (FTD) (Group C, n =30), and progressive supranuclear palsy (PSP) (Group E, n = 80). In addition, another 30 healthy people will be recruited as the control group (Group D, n=30). [18F]AV45 and [18F]MNI-958(PMPBB3) PET will be done for imaging cerebral amyloid plaque and tau protein distribution, brain MRI for obtaining structural and functional information, and neuropsychological tests for cognitive performance. Cognitive evaluation will be repeated 18 months after recruitment. In addition, APOE genotyping will be performed as well. By obtaining the neuroimaging information, such as severity of white matter change and infarction, cortical and hippocampal atrophy, and SUVRs of [18F]AV-45 and [18F]MNI-958(PMPBB3) PET, the study will be able to investigate the composite influence of cerebrovascular disease and neurodegenerative pathology on the trajectory of cognitive impairment. Group comparisons will be performed using the Chi-square test, independent t test, Mann-Whitney U test, ANOVA test, and multiple linear regression, where appropriate. Anticipation In this project, we will be able to explore the distribution patterns of amyloid plaque and tau protein among dementia patients with different etiologies, and also evaluate their influence on cognition

Rehabilitation and Prophylaxis of Anomia in Primary Progressive Aphasia

AphasiaPrimary Progressive2 more

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.
