Active clinical trials for "Alzheimer Disease"

The purpose of this study is to examine the effectiveness of support group intervention for primary caregivers of a person with dementia or similar cognitive impairment.

This XanADu Phase II study in mild Alzheimer's Disease (AD) is to assess the safety, tolerability and efficacy of Xanamem™ in subjects with mild dementia due to Alzheimer's Disease. Subjects will be randomized to receive either 10mg once daily Xanamem™ or Placebo at a 1:1 ratio in a double-blinded fashion.

The aim of this study is to investigate whether a tDCS-accompanied intensive cognitive training of working memory leads to performance improvement in individuals with prodromal Alzheimer's disease.

The study will investigate the effects on safety and pharmacokinetics (PK) of MK-1942 and donepezil when co-administered to participants with Alzheimer's Disease with mild-to-moderate cognitive impairment stably treated with donepezil. The objectives of this study include determining if the combination of MK-1942 with donepezil increases the incidence or severity of adverse events (AEs) previously reported for these agents, or results in unanticipated AEs in the patient population targeted for MK-1942 treatment. In addition, any changes in the PK parameters of either MK-1942 or donepezil as a result of co-administration will be assessed.

This Phase 1 study is a single ascending dose (SAD) and multiple ascending dose (MAD), placebo-controlled study to evaluate the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of intravenous ACU193 when administered to participants diagnosed with Mild Cognitive Impairment (MCI) or Mild Dementia due to Alzheimer's disease (AD).

Background： Dementia is a progressive, devastating, and fatal neurodegenerative disorder. Alzheimer's disease (AD) is the most common cause of dementia, accounting for more than 50% of patients with dementia. Docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), the major bioactive components of n-3 polyunsaturated fatty acids (n-3 PUFAs) , might connect to the etiology of several neuropsychiatric diseases. To our knowledge, it has never been studied to look at the different effects of DHA, EPA and their combination on associated symptoms of AD. Objectives To examine the effects of DHA, EPA and their combination on associated symptoms of AD, including cognitive function, depressive symptoms, and functional ability. Method This is a randomized, double-blind, placebo-controlled, 24-month follow-up study, enrolling 200-400 patients with mild AD (Mini-Mental Status Examination (MMSE) 19-26 or Clinical Dementia Rating (CDR) 0.5-1). Cognitive ability is assessed by the Alzheimer Disease Assessment Scale-Cognitive Subscale (ADAS-Cog) and the MMSE. Mood status is assessed by Geriatric Depression Scale (GDS). Functional ability is assessed by the Alzheimer Disease Cooperative Study activities of daily living (ADCS-ADL) and global function by the CDR, quality of life scale (QOL-AD). Brain function is assessed by resting state brain magnetic resonance imaging (MRI).

Part 1 of this study will be conducted to determine the safety, tolerability, and pharmacokinetic (PK) profile of multiple doses of TB006, as well as the maximum tolerated dose of TB006, and to assess the immunogenicity of TB006 (production of anti-TB006 antibody). Part 2 of this study will be conducted to determine the clinical efficacy of TB006 in participants with mild to severe Alzheimer's Disease.

Our aim has been determined to investigate the effect of physical exercise alone and in combination with cognitive exercise, on cognitive, physical function and quality of life in individuals with Alzheimer's Disease during the Covid-19 pandemic period.

Brain oscillations are ubiquitous in the human brain and have been implicated in cognitive and behavioral states defined in precisely tuned neural networks. In neurodegenerative disorders, neurodegeneration is accompanied by changes in oscillatory activity leading to the emerging concept of neurological and psychiatric disorders as "oscillopathies". Alzheimer's disease, which accounts for the vast majority of age-related dementias, is characterised by a prominent disruption of oscillations in the gamma frequency band. The restoration of gamma oscillations by neural entrainment in animal models of Alzheimer's disease have shown a remarkable decrease in the pathological burden of amyloid and tau via increased microglial activity, resulting in a significant increase of cognitive performances. Transcranial alternating current brain stimulation (tACS), is a neurophysiological method of non-invasive modulation of the excitability of the central nervous system that is having an increasingly numerous spectrum of potential therapeutic applications. Recent studies have demonstrated the effectiveness of this method in modulating the natural frequencies of cerebral oscillation, underlying multiple cognitive processes such as verbal memory, perception and working memory. On the basis of these premises, the treatment with gamma tACS is proposed in patients affected by Alzheimer's disease. In this randomized, double-blind, sham-controlled, cross-over study, the investigators will evaluate the modulators of response on cognitive measure to a single stimulation with gamma tACS on the posterior parietal cortex in patients with Mild Cognitive Impairment due to Alzheimer's disease.

The present study is being done in a scientifically rigorous manner, using readily available MCT oil (refined from coconut oil) versus a placebo oil to assess any cognitive and functional benefits for AD patients.
