Filter by:Mild cognitive impairment and Alzheimer's disease are conditions that involve memory difficulties. Transcranial direct current stimulation is a type of brain stimulation. It may help improve these memory difficulties. However, it works better on active brain areas. This study looks at if combining exercise and applying current to important parts of the brain can help improve memory in people with Mild Cognitive Impairment or Alzheimer's disease.
In this study, the investigators will be examining the effects of the deep repetitive transcranial magnetic stimulation (rTMS) using the H1 coil in patients over the age of 60 diagnosed with mild to early-moderate Alzheimer's disease (AD) or mild cognitive impairment (MCI) and comorbid Major Depressive Disorder (MDD) who have been unable to tolerate or failed to respond to antidepressant medications. The coil was designed to stimulate deeper regions of the left dorsolateral prefrontal cortex (DLPFC). Based on prior research, the investigators propose that active stimulation with the H1 coil for 4 weeks may result in significant remission rates and will be tolerable and safe.
The purpose of this study is to measure cerebrospinal fluid (CSF) clearance. CSF cushions the brain from impact and carries waste products from the brain to the bloodstream. This process is known as clearance. Researchers have considered that impaired clearance of amyloid (a protein) from the aging brain causes buildup of amyloid in the brain and plays a role in increased risk for Alzheimer's disease. However, until recently, there has not been a method to measure CSF clearance. This study will examine CSF clearance using positron emission tomography (PET) scanning, which creates images of structures in the body and their functioning. This study will also measure the amount of two proteins, tau and amyloid, in the brain. Tau and amyloid are proteins that build up in the brains of people with Alzheimer's disease. An investigational compound (tracer) called [18F]MK-6240 is injected into the blood prior to the scan in order to take images of the CSF clearance and measure tau protein in the brain. This tracer is considered investigational because it is not approved by the US Food and Drug Administration (FDA) for clinical use and is only being used for research purposes.
The Etude Study is a multi-center, four-arm prospective dose-adjusting study designed to assess the tolerability, safety and efficacy of non-invasive sensory stimulation for patients with cognitive impairment.
Multi center study of six Memory Clinics in four Nordic countries in validating a prognostic diagnostic investigation of qEEG in Mild Cognitive Impairment (MCI). The study is in two parts, the first one is a follow up of a previous study conducted in 2011-2013 and the second half is new recruitment with two years follow up. End points are diagnosis of a dementing disorder, primarily dementia of Alzheimer´s type.
Electrical activity in the brain known as "gamma" brainwaves help connect and process information throughout the brain. These gamma waves are diminished in Alzheimer's disease. New research in Alzheimer's disease mouse models shows that exposure to light flickering at the rate of 40 flashes per second or 40Hz increased gamma brainwaves and led to clearing of beta amyloid plaques in the brain, a key abnormality in Alzheimer's disease. This project will test the ability of a novel iPad App (AlzLife https://www.alz.life/) that delivers light therapy at 40 Hz combined with cognitive therapy to improve cognition, function, and quality of life in Alzheimer's disease.
About the research There are currently 850,000 people living with dementia in the United Kingdom. It is now understand that Alzheimer's disease (AzD) can result from damaged blood vessels in the brain. Brain blood flow can be measured using ultrasound, known as transcranial Doppler ultrasonography (or TCD). Brain training (BT) uses exercises or brain-teasers to try to make the brain work faster and more accurately. In recent years, BT has been used to try to improve memory, mood, learning, quality of life, and ability to carry out every-day activities in people with dementia. Aims 1. To find out how acceptable and manageable this BT program is for people with dementia to undertake larger studies of BT in the future. 2. To look for any benefits for people with dementia, such as, improvements in quality of life, ability to carry out everyday tasks, mood, and brain blood flow. How will the research be carried out? - Forty patients with AzD, or mild cognitive impairment (MCI), and twenty healthy older adults will be recruited from memory and geriatric clinics, Join Dementia Research, general practice surgeries and community groups. - Participants will be randomly assigned to brain training or control. The control group will be offered the program at the end of the study. - First visit: Participants will complete questionnaires on quality of life, mood, everyday abilities, memory and an assessment of brain blood flow - Brain training program: Participants will complete 15-30 minute sessions, 3-5 times per week - Follow-up: participants will repeat the questionnaires and assessment of brain blood flow - Interviews and feedback: to discuss how participants felt the program went, and find out if there are any ways it could be improved.
This multicentre randomized controlled trial aims to evaluate the effects of an intervention consisting of a TV-based Assistive Integrated Service developed to improve the quality of life in older people with mild cognitive impairment or mild dementia (PMCI/MD) and their informal caregivers. This study is a collaboration between four European countries (Spain, Romania, Italy and Switzerland) and the clinical trials will be conducted in two of these countries (Spain and Romania) In total 240 dyads, consisting of a person with mild cognitive impairment or mild dementia and their informal caregiver will be recruited for this study. Participant dyads will be randomized in a 1:1 ratio in two parallel groups: to receive either usual care from primary or specialized providers (control group) or to receive usual care plus access to a device with the Tv-AssistDem platform (intervention group). Participants in the trial will be assessed for a period of 12 months. After the baseline visit, all participants will have follow-up visits every 6 months together with a checkup of the PMCI/MD capacity to remain in the study. In the follow up visits, investigators will assess the PMCI/MD quality of life, caregiver's quality of life and burden, patient treatment adherence, patient functional status and service utilization. A user-behaviour analysis and usability evaluation will also be performed.
The LUCINDA Trial is a three-site, phase II, randomized, double-blind, placebo-controlled study of leuprolide acetate (Eligard) in women with Mild Cognitive Impairment or Alzheimer's Disease taking a stable dose of a cholinesterase inhibitor medication like donepezil. Its objective is to assess the efficacy of a 48-week regimen of leuprolide (22.5 mg per 12 weeks) compared to placebo on cognitive function, global function and plasma and neuroimaging biomarkers.
Repetitive transcranial magnetic stimulation (rTMS) or transcranial direct current stimulation (tDCS) has been used for the modulation of mild cognitive impairment (MCI) patients' cognitive function by altering the cortical excitability. Recently, more challenging approaches, such as stimulation of two or more sites or use of dual modality have been studied in MCI patients. In this study, simultaneous stimulation using both facilitatory rTMS (10Hz) and anodal or cathodal tDCS (dual-mode stimulation) over bilateral dorsolateral prefrontal cortices (DLPFCs) was investigated to compare its modulatory effects with single facilitatory rTMS stimulation in mild cognitive impairment patients.
