Gulf War Illness (GWI) is a multi-symptom disorder that is characterized by complex traits such as fatigue, headaches, joint pain, insomnia, and memory problems. With no treatment for GWI currently available, there is an urgent need to develop novel interventions to alleviate major GWI clinical complications. Recent evidence highlights the potential value of flavonoids, a subclass of organic chemical called polyphenols abundantly found in some plants and common dietary preparations, in helping relieve clinical complications in Veterans with GWI. The overall goal is to test whether daily consumption of commercially available Concord grape juice, which is very Flavonoid-rich, is effective for treating cognitive deficits and chronic fatigue in Veterans with GWI.
Gulf War Illness (GWI) is a multi-symptom disorder that is characterized by complex traits. Clinical complications of GWI typically persist over long-term, cause significant pain and suffering, and interfere with the ability of affected Veterans to successfully integrate back into civilian society. There is no treatment for GWI and there is an urgent need to develop novel interventions either to resolve underlying GWI mechanisms, or to alleviate major GWI clinical complications. Recent Evidence highlights the potential value of flavonoids, a subclass of organic chemical called polyphenols that are abundantly found in some plants and common dietary preparations may help alleviate chronic fatigue and preserve cognitive functions. Based on this, the overall goal is to test whether the potential efficacy of dietary supplementation with a commercially available flavonoid-rich product, alleviates clinical complications in Veterans with GWI. In particular, the researchers propose a randomized, double-blind, placebo-controlled Phase I/IIA study to test the feasibility and potential efficacy of Concord grape juice dietary supplementation to treat cognitive deficits and chronic fatigue in Veterans with GWI.

Brief Symptom Inventory (BSI)
to assess safety and tolerability to treatment. The test is a 53-item self report scale that uses the 5 point Likert scale.
Time frame: 6 months
Patient Health Questionnaire-15 (PHQ-15)
to assess safety and tolerability to treatment. The Patient Health Questionnaire 15 (PHQ 15) is a validated measure of somatic symptom severity in functional somatic syndromes (FSS). Scale ranges from 0-30 (mild to severe).
Time frame: 6 months
California Verbal Learning Test-Second Edition (CVLT-II)
This test looks at cognitive functioning by assessing immediate recall and long-delayed recall.
Time frame: 6 months
The Chalder Fatigue Questionnaire
The Chalder Fatigue Questionnaire assess chronic fatigue. Each of the 11 items are answered on a 4-point scale ranging from the asymptomatic to maximum symptomology
Time frame: 6 months
Wechsler Adult Intelligence Scale (WAIS-IV)
The Digit Span subtest is a widely used measure of auditory attention that is well-normed and sensitive. The subtest has three parts - digits forward, backward, and sequencing.
Time frame: 6 months
the Conner's Continuous Performance Test-3 (CPT-3)
The CPT-3 assist in clinical assessment of attention problems. The patient is instructed to press the space bar (or mouse button) immediately following the presentation of specific letters on screen. The test normally takes 14 minutes to administer.
Time frame: 6 months
the Trail Making Test (TMT)
The TMT consists of two forms, parts A and B. This measure taps both simple graphomotor speed (Part A) and adds in a rapid set-shifting paradigm that taps executive functioning (Part B).
Time frame: 6 months
Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV) Block Design Subtest
A tool for testing adult intelligence level.
Time frame: 6 months
the Stroop Test
The Stroop Color and Word Test consists of a Word Page with color words printed in black ink, a Color Page with 'Xs' printed in color, and a color-Word Page with words from the first page printed in colors from the second page (the color and the word do not match). The respondent goes down each sheet reading words or naming the ink colors as quickly as possible within a time limit. The test yields three scores based on the number of items completed on each of the three stimulus sheets. An Interference score, which is useful in determining the individual's cognitive flexibility, creativity, and reaction to cognitive pressures also can be calculated.
Time frame: 6 months
Halstead Category Test
This test takes approximately 30 minutes and consists of 120 items, presented visually. The participant must decipher the underlying principle of the stimulus set. Total number of errors will be used.
Time frame: 6 months
Brief Visuospatial Memory Test-Revised (BVMT-R)
A tool to measure visuospatial learning and memory abilities.
Time frame: 6 months
Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV) Digit Span Subtest
Digit Span measures short-term auditory memory and attention.
Time frame: 6 months
