Study of Bacopa in Gulf War Illness Patients
What this study is about
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.
View original scientific description
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.
Interventions
DIETARY_SUPPLEMENT
BacoMind® (Bacopa monnieri standardized extract)
BacoMind® (Bacopa monnieri standardized extract) 300 mg daily capsule.
DRUG
Placebo
Daily placebo capsule identical in size, color, and shape to that of the Bacopa capsules.
Primary outcome measures
California Verbal Learning Test (CVLT-II) Assessment
Time frame: 12 weeks
Change in mean CVLT-II long delay free recall from baseline to 12 weeks. Higher CVLT-II scores are considered clinically better, and the raw CVLT-II scores will be used in analyses and reporting.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Born in years 1942 to1978
- Served in the Gulf War theater for any period between August 1990 and July 1991
- Meets modified Kansas case definition criteria and CDC case definition for Gulf War Illness (GWI). The modified Kansas definition, which includes the CDC criteria includes:
- Allowance for normal illnesses of aging, such as hypertension and diabetes if the conditions are treated and are in demonstrable stable and normal ranges at the time of screening and assessment.
- Allowance of stable comorbid conditions such as post-traumatic stress disorder (PTSD), major depressive disorder (MDD), and traumatic brain injury (TBI) that have not required hospitalization in the 5 years prior to recruitment. Severe TBI is excluded.
- Able to consent to the study
- Participants of childbearing potential must practice effective contraception during the study so that, in the opinion of the Investigator, they will be compliant with birth control measures during the study.
- Agrees to participate in follow-up visits.
Exclusion criteria
- They are scheduled for a surgery during the period of study participation, had minor surgery within 3 months prior to screening, or had major surgery within 6 months prior to screening,
- Self-report of current untreated major depression with psychotic or melancholic features (as determined by self-report), schizophrenia, bipolar disorder, delusional disorders, dementias of any type, or substance abuse during the last two years (excluding cannabis products),
- Any serious allergic disease (self-report), possibly resulting in anaphylaxis, such as food/drug allergies, including allergic asthma, or allergy to any ingredient of the active product or placebo, including allergies to FD\&C Yellow No. 5 (tartrazine),
- Renal disease (self-report; laboratory results: renal insufficiency with serum creatinine \> 2.0 mg/dL or eGFR \< 44; or currently on renal dialysis),
- Hepatic insufficiency (bilirubin \>2.5mg/dL or transaminases \>3x the upper limit of normal (ULN)). Participants with Gilberts syndrome are eligible for the study if other liver function tests are normal, regardless of bilirubin level,
- Pregnancy (premenopausal female participants),
- Current heavy alcohol or tobacco use (self-report). Heavy use is defined as alcohol consumption not to exceed approximately 15 drinks per week (with a drink defined as 12 oz beer, 5 oz wine, or 1.5 oz distilled spirits) and tobacco use not to exceed 20 cigarettes (or equivalent) per day.
- Current exclusionary diagnosis that could reasonably explain the symptoms of their fatiguing illness and their severity, using the exclusion criteria best described in the Ambiguities in case definition paper for Chronic Fatigue Syndrome (CFS), as described in detail in Reeves et al., 2003, which clarifies exclusionary conditions. Specifically, the exclusionary diagnoses that are not otherwise listed above comprise:
- organ failure (e.g., emphysema, cirrhosis, cardiac failure, chronic renal failure)
- chronic infections (e.g., AIDS, hepatitis B or C) or inflammatory bowel disease (IBD) (via self report)
- major neurologic diseases that could cause fatigue or neurologic deficits such as (e.g., epilepsy, stroke, brain tumor, multiple sclerosis, Parkinson's Disease, Alzheimer's disease) or history of CNS demyelinating disease (e.g., multiple sclerosis, neuromyelitis optica spectrum disorder) (Self report),
- cancer or cancer treatment (e.g., chemotherapy, radiation of brain), or current use of biologic modifiers that could affect immune function (e.g., Etanercept, Rituximab) (self-report)
- untreated primary sleep disorders (e.g., sleep apnea, narcolepsy)
- uncontrolled diabetes (HgbA1c \> 7)
- Temporary conditions discovered at screening for which participants may be rescreened 6 weeks after resolution of condition.
- Temporary effects of medications
- Temporary sleep deprivation
- Untreated hypothyroidism/hyperthyroidism, hypothyroidism/hyperthyroidism that has been inadequately controlled during the last 3 months, or free T4 level not within normal limit
- Active infection
- Participating in another interventional clinical trial of an investigational therapy (including social-behavioral therapy) within 6 weeks prior to consent to participate in this study, or planning to participate in another interventional clinical trial of an investigational therapy during this study,
- Use of Bacopa within 6 weeks prior to the enrollment in this study,
- Diagnosed bleeding disorder or current use of anticoagulants and/or antiplatelets, except for low dose nonsteroidal anti-inflammatories (NSAIDS).

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
