Filter by:The aim of the study is to investigate whether the effect of disorientation on physical motion and gait among dementia patients, can be reliably measured in a laboratory environment, by means of a virtual reality (VR) experimental setup.
This is a long-term, prospective, interventional study to investigate the role and prevalence of subclinical epileptiform activity in the hippocampus in patients with mild cognitive impairment (MCI) due to Alzheimer's disease (AD). The investigators would like to investigate whether subclinical epileptiform activity in the hippocampus is more prevalent in patients with MCI, compared to healthy controls and to evaluate its effects on cognitive decline. Evolution of cognitive decline will be assessed over a time period of two years.
This is a research study that aims to examine whether Veterans with mild Traumatic Brain Injuries are at risk for dementia by studying their memory, brain wave activity, brain structure and proteins that can be elevated after brain injury and in dementia.
This open-label pilot study examines whether the hallucinogenic drug, psilocybin, given under supportive conditions, is safe and effective for depression in people with Mild Cognitive Impairment (MCI) or early Alzheimer's Disease (AD). This study will also assess whether psilocybin may improve quality of life in those individuals.
A phase 1 randomised, placebo-controlled, single-blind study to characterise the biomarker effects of the CSF-1 receptor antagonist JNJ-40346527 in participants with mild cognitive impairment. A maximum of 54 participants will be recruited to the two part study. The first part of the study will identify whether it is possible to identify biomarkers that may be used in future studies with JNJ-40346527 and part 2 will investigate a minimal efficacious JNJ-40346527 dose.
The study aimed to investigate whether high definition transcranial direct current stimulation (HD-tDCS) could benefit global cognitive function and sub-domains of cognition (visual/verbal/working memory, executive function, attention, processing speed, language, and frontal lobe function), mood (depression and anxiety), and subjective memory impairment in patients with mild cognitive impairment.
Widespread recognition of the current and projected impact of the dementia epidemic has spurred research into novel drug discovery efforts. It is well recognized by most that Alzheimer's disease is not the only form of dementia and that beginning to turn attention to other disease states is critically important in order to alleviate this burden on the elderly population today This proposal seeks to further progress in this area through the repurposing an existing drug therapy as a potential treatment for Hippocampal Sclerosis of Aging. This disease is seldom recognized clinically and yet is the number one Alzheimer's disease mimic the confounds are diagnostic and treatment of subjects suffering from dementia and as of yet has no potential therapeutic interventions identified. As such, the proposed study represents a cutting-edge, data-driven, low-cost, exploration of a novel disease relevant pathway that may hold promise for global efforts targeting late life dementia which is a major health priority in America today.
The Boston Cognitive Assessment (BoCA) is a self-administered online test intended for longitudinal cognitive monitoring. BoCA uses random not-repeating tasks to minimize learning effects. BoCA was developed to evaluate the effects of treatment in longitudinal clinical trials and available gratis to individuals and professionals.
The prevalence of neurodegenerative diseases is expected to increase over the next years, in parallel to the aging of the world population. Therefore, research efforts need to be devoted to evaluate intervention strategies that delay the onset of cognitive decline. Given the paucity of pharmacological interventions, strategies for non-pharmacological enhancement, such as cognitive training, are receiving increasing attention. Moreover, the advances in the development of Information & Communication Technologies (ICT) has recently prompted the possibility to develop computer-based solution, also called Serious Game (SG), for the training of one or more cognitive functions. This approach could help overcome the limits of traditional paper-and-pencil cognitive intervention techniques. However, the clinical, ethical, economic and research impact of the use of these computer-based solutions in these target populations is still under discussion. In order to acquire more academic and professional credibility and acceptance, researchers need to collect more data to test and evolve usability and usefulness of SG as clinical tools targeting people with dementia-related disorders. The general aim of this research is to evaluate the effects of a computer-supported Cognitive Training (CT) compared to a paper-and-pencil CT, in the early stage of neurodegenerative diseases. Patients with Mild Cognitive Impairment (MCI) are enrolled and randomly assigned to the experimental group (CoRe software) or control group (paper-and-pencil CoRe version). All patients are evaluated before (T0) and after (T1) treatment with an exhaustive neuropsychological assessment. Furthermore, follow-up visits are scheduled 6 months (T2) and 12 months (T3) after the end of the treatment.
Recent findings suggest that sleep disruption may contribute to the generation and maintenance of neuropsychiatric symptoms including anxiety, depression, agitation, irritation, and apathy while treating sleep disruption reduces these symptoms. Impairments in the neural systems that support emotion regulation may represent one causal mechanism mediating the relationship between sleep and emotional distress. However, this model has not yet been formally tested within a sample of individuals with or at risk for developing Alzheimer's Disease (AD) This proposal aims to test a mechanistic model in which sleep disturbance contributes to neuropsychiatric symptoms through impairments in fronto-limbic emotion regulation function in a sample of individuals at risk for developing, or at an early stage of AD. This study seeks to delineate the causal association between sleep disruption, fronto-limbic emotion regulation brain function, and neuropsychiatric symptoms. These aims will be achieved through a mechanistic, randomized 2-arm controlled trial design. 150 adults experiencing sleep disturbances and who also have cognitive impairment with the presence of at least mild neuropsychiatric symptoms will be randomized to receive either a sleep manipulation (Cognitive Behavioral Therapy for Insomnia CBT-I; n=75) or an active control (n=75). CBT-I improves sleep patterns through a combination of sleep restriction, stimulus control, mindfulness training, cognitive therapy targeting dysfunctional beliefs about sleep, and sleep hygiene education. Neuropsychiatric symptoms, fronto-limbic functioning, and sleep disruption will be assessed at baseline and at the end of the sleep manipulation through functional Magnetic Resonance Imaging (fMRI), clinical interviews, PSG recordings, and self-report questionnaires. Neuropsychiatric symptoms (anxiety and depression) and sleep disturbance (actigraphy, Insomnia Severity Index, and sleep diaries) will be assayed at baseline and each week throughout the sleep manipulation to assess week-to-week changes following an increasing number of CBT-I sessions. Wristwatch actigraphy will be acquired from baseline to the end of the sleep manipulation at week 11. Neuropsychiatric symptoms and sleep will be assessed again at six months post-manipulation.
