Cerebrovascular and Cognitive Improvement by Resveratrol (resVida) and Fruitflow-II (CCIRF-II)

Neurolgy Institute for Brain Health and Fitness80 enrolled

Overview

The purpose of this study is to determine whether Fruitflow-II, Resveratrol (resVida), alone or in combination, are effective in the treatment of memory problems in adult patients with memory impairment. We also evaluate effects of these medications on blood flow to the brain and fitness, to find whether the possible improvement in memory is associated with the alterations in these parameters.

Accumulating evidence suggests that tomato consumption has cardiovascular benefits, primarily through increasing blood flow in vivo; the active ingredient in tomato, or its extract (Fruitflow) have been shown to inhibit glycoprotein IIb/IIIa, similar to aspirin (which has antiplatelet activity and is used for secondary prevention of cardiovascular and cerebrovascular events in patients). Considering the fact that Fruitflow can improve the platelet function and peripheral blood flow, we hypothesized that Fruitflow can also increase the blood flow in the brain and thereby possibly enhance memory and cognitive function in middle-aged or elderly people who have memory complaints. Therefore, the initial goal of our study is to evaluate the effects of Fruitflow on brain blood and cardiovascular function by using Transcranial Doppler ultrasound (to check for changes in cerebral blood flow), cardiovascular fitness testing (to check for changes in VO2-max and stroke volume), and neurocognitive evaluation (to check for changes in memory and executive function). Many pathways such as inflammation and oxidative stress are involved in the pathophysiology of memory loss with ageing. Recent studies have shown that a natural compound found in the skin of red grapes and also in wine, called "Resveratrol", have beneficial effects for prevention of cognitive decline by reducing inflammation and improving cardiovascular function. Therefore, our next goal is to evaluate whether administration of Resveratrol, by itself or in combination with Fruitflow, can improve brain blood flow, VO2-max, and cognitive performance. Thus our clinical trial will have the following 4 arms: Fruitflow, Resveratrol, Fruitflow/Resveratrol combination, and placebo for each supplement. The results of the study will potentially provide evidence that these natural supplements can have significant cardioprotective and neuroprotective properties in middle-aged and elderly adults. Subjects (between 50 and 80 years old) complaining of memory problem who have MMSE (Mini-Mental State Examination) above 27 will be recruited from patients of Dr. Majid Fotuhi (PI at the Neurology Institute for Brain Health and Fitness). Flyers at the institute and advertisement in Baltimore will provide information about the opportunity to enroll in an observational study for 3 months, along with eligibility criteria. Participants will continue to receive routine and standard care, while data on outcome (i.e., dependent) variables and mediators will be collected over three study visits: Day 1: at the onset of their participation: Assessment of memory and Cardiovascular Fitness Testing (CFT) Day 2: Blood Test and Transcranial Doppler (TCD) Ultrasound at time 0 and 3 hours after taking the first dose of the supplements; Month 3: Assessment of memory, Cardiovascular Fitness Testing, and Transcranial Doppler Ultrasound 3 months after daily treatment with supplements in each group.

Outcomes

Primary Outcomes

Evidence of improvement in memory after treatment with Fruitflow-II, resVida (Resveratrol), alone or in combination

The following tests will be used for evaluating cognitive function: 1. Cambridge Neuropsychological Test Automated Battery (CANTAB). We use 5 tests which are mostly related to memory functioning including following: * Visual memory tests incuding (A) Paired Associates Learning (PAL) and (B) Pattern Recognition Memory (PRM) * Executive function, working memory and planning tests including (A) Stockings of Cambridge (SOC) and (B) Spatial Working Memory (SWM) * Semantic/verbal memory tests including (A) Verbal Recognition Memory (VRM) 2. Trail-Making Test (TMT) 3. Verbal Fluency Test

Time frame: 3 months

Secondary Outcomes

Maximal VO2 (VO2 max)

Aerobic fitness (VO2 max) will be assessed by graded maximal exercise testing on a stationary bicycle. Oxygen uptake (VO2) will be measured from expired air samples to be taken at 30-s intervals until a maximal VO2 (VO2 max) is attained or to the point of test termination secondary to symptom limitation and/or volitional exhaustion. VO2 max will be defined as the highest recorded VO2 value when two of three criteria are satisfied: (1) a plateau in VO2 peak between two or more workloads; (2) a respiratory exchange ratio \>1.00; and (3) a heart rate equivalent to their age-predicted maximum.

Time frame: 3 months

Blood Flow to the Brain

Cerebral blood flow velocity will be measured in the middle cerebral artery (MCA) and basilar artery (BA) using Transcranial Doppler ultrasonography.

Time frame: 3 months
