Fall Prevention - Vestibular Rehabilitation
Alzheimer Dementia (AD)Vascular DementiaA feasibility study of a vestibular rehabilitation program in a sample of cognitively impaired clinical patients to guide future trials.
Caregiver Outcomes of Alzheimer's Disease Screening
Alzheimer DiseaseThis study will measure the risks and benefits of early screening of Alzheimer's disease. Early diagnosis through screening may enhance the family member's transition to a family caregiver and reduce caregiver burden by providing an opportunity for the family member to learn about the syndrome, receive interventions, and to prepare for their new care giving role.
Risk Reduction for Alzheimer's Disease
Cognitively Normal Older AdultsHypertension2 morePhysical inactivity, high blood pressure and dyslipidemia are risk factors for Alzheimer's disease (AD) and vascular dementia. Importantly, these risk factors are modifiable with lifestyle changes, pharmacological treatment, or both. The rrAD study will determine effects of aerobic exercise training and intensive vascular risk reduction on cognitive performance in older adults who have high risk for AD.
BDPP Treatment for Mild Cognitive Impairment (MCI) and Prediabetes or Type 2 Diabetes Mellitus (T2DM)...
Mild Cognitive ImpairmentAlzheimer's DiseaseMild Cognitive Impairment (MCI) represents a group of persons who are at risk of incident dementia in the near-term. Persons with MCI who have deficits in short-term recall (amnestic MCI) are at significant risk of incident Alzheimer's disease (AD) (termed prodromal AD), and thus represent a worthy target for secondary prevention interventions. There is increasing evidence that risk factors for metabolic syndrome (such as prediabetes and type 2 diabetes) increase risk of incident cognitive impairment and possibly AD, and evidence that the neurons of the AD brain are in fact insulin resistant with diminished glucose uptake under physiological conditions. Thus, persons with MCI and prediabetes or type 2 diabetes may be at particular risk of incident cognitive impairment and AD. A large clinical trial (ACCORD)1 demonstrated that tight control of peripheral blood glucose does not improve cognitive (or other health) outcomes in older persons with peripheral insulin resistance. Thus, there is a need to target cognitive outcomes in persons with MCI and metabolic risk factors, and a drug targeting insulin resistance with good blood-brain-barrier (BBB) penetrance can potentially accomplish these objectives. While there is a phase III study of intranasal insulin targeting this strategy, nutraceuticals offer a low-tech solution that would be more suitable to future secondary prevention trials in MCI. Bioactive Dietary Polyphenol Preparation (BDPP) is a combination of two nutraceutical preparations grape seed polyphenolic extract (GSE), and resveratrol that contain abundant concentrations of polyphenols. The investigators have found that oral BDPP administration was associated with improved cognition and brain plasticity long-term potentiation (LTP) in mouse models of metabolic syndrome and AD, as well as lowering brain amyloid and tau burden in an AD mouse model2-4. The investigators have demonstrated excellent absorption of oral BDPP in a small study in humans and similarly excellent CSF penetration of oral BDPP in rats, but it is crucial to demonstrate safety and CSF penetration of oral BDPP in humans to assess its potential as a treatment for MCI and prediabetes or type 2 diabetes.
Improving Beta-2 Adrenergic Signaling in Alzheimer's Disease
Alzheimer's DiseaseCognitive DysfunctionThe purpose of this study is to test the effects of long-term therapeutic doses of formoterol, on a) cerebrospinal fluid (CSF) tau levels, and Amyloid Beta protein 40/42 levels in the CSF, and b) cognitive function in people with mild to moderate Alzheimer' Disease (AD).

Dosage and Efficacy of Probucol-induced apoE to Negate Cognitive Deterioration
Dementia of the Alzheimer TypeAge-related Cognitive Decline1 moreDEPEND is an open-label but dosage-masked trial of the retired cholesterol-lowering drug probucol as an agent to increase availability of apolipoprotein E (apoE) in the cerebrospinal fluid (CSF) of cognitively intact older persons at risk of Alzheimer's dementia. Absorption of oral probucol is variable. In a sample of 23 cognitively intact persons over age 55, DEPEND will therefore develop an algorithm to prescribe individualized dosing to achieve plasma concentration that will likely increase availability of CSF apoE. These persons will then use their individualized dosage for 12 months to assess longer-term effects of the drug on CSF apoE concentration, while monitoring closely for evidence of adverse consequences of use.
Control and Intervention Programme on Alzheimer's Disease Risk Factors
Alzheimer's DiseaseRecent epidemiologic studies are identifying a number of modifiable risk and protective factors that may influence in the incidence of Alzheimer's disease (AD). Therefore, the combination of an early detection of individuals at risk together with interventional studies targeted to the control of modifiable risk factors makes primary prevention programmes to become a new and real therapeutic strategy. In this scenario, the investigators have designed the ALFAlife study, a programme of control and intervention on the modifiable AD risk factors. Throughout this study, participants will be given a number of healthy lifestyle guidelines that are personalised depending on their specific risk profile. These guidelines refer to smoking and dietary habits and physical, cognitive and social activity. The investigators hypothesis is that the follow-up of these guidelines will favor a change of participants' lifestyle habits towards healthier ones. In addition, the investigators hypothesise that changes in these lifestyle habits will have an effect on objective physiological measures (such as blood pressure and cholesterol levels).
Modulation of Micro-RNA Pathways by Gemfibrozil in Predementia Alzheimer Disease
Preclinical Alzheimer's DiseaseThe purpose of this study is to assess the safety and efficacy of gemfibrozil in modulating microRNA-107 levels for the prevention of Alzheimer's disease in subjects with intact cognition and mild cognitive impairment
Brain-Computer Interface System for Training Memory and Attention in Elderly
Alzheimer's DiseaseMild Cognitive Impairment2 moreThe primary objective is to examine the efficacy of 8-weeks of a locally developed brain-computer interface based system intervention for improving attention and memory in healthy elderly and those with age related cognitive decline. We hypothesize that elderly who have completed the training program will have significant improvement in their attention and memory compared to the controls, based on the Repeatable Battery for the Assessment of Neuropsychological Status.
