The purpose of this study is to assess whether a high quality preparation of ubiquinone (coenzyme Q10) benefits symptoms, function, and quality of life in veterans with Gulf War illness.
The study addresses the pre-clinical promise of Montelukast (MLK) for improving brain function in veterans with Gulf War Illness (GWI). MLK, a US Food and Drug administration (FDA)-approved drug for asthma, has shown efficacy in an animal model of GWI to improve cognitive and mood function through modulation of leukotriene signaling and suppression of neuroinflammation.
Many veterans with Gulf War Illness developed chronic gastrointestinal symptoms during their deployment to the Persian Gulf. The pathophysiologic mechanisms of these chronic gastrointestinal symptoms are not well understood but cause significant morbidity in veterans. Our proposed studies will provide an innovative and novel treatment trial for chronic gastrointestinal symptoms in veterans with Gulf War Illness that were deployed into war zones. Given that there are currently no specific treatments for these disorders, and that current symptomatic approaches are far from ideal, proof of principle of our trial would be an extremely important advance as it would not only have a beneficial impact on the health of many thousands of our veterans, but also it would substantially reduce the many negative economic effects of this ailment on the VA Health Care System.
The investigators goals are to identify blood lipids/metabolites that correlate with cognitive decline in the presence of the APOE ε4 allele among veterans with GWI. To determine the effect of dietary, medical and biological factors that influence lipid and metabolites in blood from GW veterans. To identify blood lipid/metabolite profiles that correlate with bioenergetics deficits and glial activation in the brains of GWI. To validate blood biomarker signatures of GWI using APOE genotyping and blood lipids/metabolites that correlate with the CNS dysfunction in GWI.
This clinical trial aims to confirm previous findings from a smaller study which demonstrated significant improvements in all symptoms among veterans with Gulf War Illness after one month on the dietary intervention. The main objectives of this study are: 1) to confirm previous findings of treatment response to the diet in a larger and more diverse group; 2) to examine how changes in the nervous system may be the reason for improvement; and 3) to identify markers which change in the blood after one month on the diet. Participants will have baseline measures collected and then will be randomized into the intervention or wait-listed control group, which they will follow for one month before being reassessed.
The purpose of this study is to determine whether a behavioral sleep treatment improves sleep and other Gulf War Illness (GWI) symptoms in Gulf War Veterans with GWI.
Gulf War Illness is a condition that affects multiple major organ systems, resulting in a diverse array of symptoms that include debilitating fatigue, memory and cognition difficulties, headaches, sleep disturbances, gastrointestinal problems, skin rashes, and musculoskeletal/joint pain. This phase II, double masked, randomized, placebo-controlled, two-arm study will evaluate cognitive function as evidence of efficacy of the nutraceutical intervention, Bacopa, on central nervous system symptom management of Gulf War Illness, along with assessments of safety of the intervention.
This study aims to look at the long term efficacy of using repetitive transcranial magnetic stimulation (rTMS) in relieving Gulf War Illness related headaches and pain.
A debilitating and common symptom in Gulf War Illnesses (GWI) is the inability to retrieve words. This affects one's conversations, ability to fluidly exchange information verbally and retrieve information from memory. The investigators have discovered 3 brain regions - the PreSupplementary Motor Area (preSMA), caudate nucleus, and the thalamus - that are essential for word retrieval. They have also detected abnormal EEG signals related to these regions in GWI patients who have problems retrieving words. The investigators have used their model of verbal retrieval to design a noninvasive, nonpharmacological treatment that uses High Definition transcranial Direct Current Stimulation (HD tDCS). Using HD tDCS, they deliver small amounts of electric current to areas of the head to stimulate specific brain regions. The objective is to determine if delivery of HD tDCS over the preSMA will improve performance in GWI veterans with a verbal retrieval deficit. The investigators will administer pre-treatment tests of verbal retrieval measures while recording brain electrical activity. They will then administer 10 sessions of HD tDCS over the preSMA (20 minutes a session) in half the veterans. The other half will go through the same procedures, except the current will not be turned on (called the sham condition). The investigators will then compare performance between the "active" and sham group and assess if the treatment had a significant effect on performing verbal retrieval tasks and if there is a change in the ERP markers to account for how the treatment worked. If the treatment is found to be effective it will be offered to those in the sham group at the study's end. The investigators predict this treatment regimen will lead to positive effects on a person's daily functions, especially improved conversational abilities, with few, if any, side effects. They hope to outline the standard procedures for physicians to perform the treatment by creating a manual on how to apply the treatment in a clinical setting so that it will be quickly available to use in multiple sites if the proposed study demonstrates that it is efficacious. This treatment can be made widely available for Warrior Transition Units, military clinics, and VA medical centers. In addition, if successful, this could potentially lead to development of other targets of stimulation to improve other cognitive deficits in GWI, and help alleviate verbal fluency deficits associated with other disorders.
Gulf War Illness (GWI) affects an estimated 25-32% of the over 700,000 coalition troops deployed to the Persian Gulf as part of the First Gulf War. GWI causes a range of pain, fatigue, gastrointestinal, skin, neurologic, and respiratory symptoms. New treatments to reduce GWI-associated morbidity are critically needed. Research suggests a role for the gastrointestinal microbiome in mediating health, including through impacting metabolism and immunity. The disruption of this microbiome plays a role in multiple diseases, and preliminary data suggest that Veterans with GWI have altered gut microbiota. The investigators will evaluate the effectiveness of a dietary fiber prebiotic supplement intervention on improving the quality of life of Veterans with GWI.
