Brief Summary:


The cause of fatigue is not well understood. It can be felt differently by different people. Some people think there are different types of fatigue, with different causes. Researchers think a therapy to treat one type of fatigue in one condition should be able to treat that type of fatigue in other conditions.


To understand the types of fatigue.


Adults 18 and older who have felt fatigue for more than a month, and non-fatigued adults


Participants will be screened with a physical exam, their medical history, a vision test, and blood and urine tests.

Participants will begin to track the foods they eat.

This study will involve up to 10 visits. Each visit will last no more than 4 hours.

In Stage 1, participants will have an interview, fill out questionnaires, and play computer games. They will take walking and handgrip tests. They will give blood, urine, and saliva samples. They will wear a wrist monitor at home for 7 days and write down their activities. They will be put into a group: fatigue or non-fatigued control.

In Stage 2, participants will answer questionnaires and give a blood sample. They will have heart tests. They may take exercise and lung function tests that include wearing a nose clip. They may have an optional brain MRI: They may wear an electrode cap on their head during the scan to measure brain activity. They will lie on table that slides into a cylinder. They may perform tasks in the scanner.

After the study, participants might be contacted about other studies.

Primary Outcome Measures :
  1. The primary outcome will be the fatigue level using the Fatigue Numeric Rating Scale (FNS) score. [ Time Frame: Stage 1 ]

Secondary Outcome Measures :
  1. Secondary outcomes of the study will obtain common fatigue dimension information from participants that will allow us to better define phenotypic clusters that ultimately can be used for hypothesis generation, these include patient-reported outc... [ Time Frame: All time points ]

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes
Sampling Method:   Non-Probability Sample
Study Population
Participants will be recruited via a stepwise approach. Limited recruitment will occur during the first 6 months to 12 months after initial IRB approval, as part of the feasibility assessment. During this time, NIH investigators such as those from NINR, the NIDCR Sjogren s Clinic, and the 16-N-0058 study (Myalgic Encephalomyelitis/Chronic Fatigue Syndrome) will be informed about the study. These investigators will not actively recruit their own patients for the study but will be asked to post a recruitment flyer in their clinics. After the first year, the study will open to the general population.

All Participants

  • Adult participants aged greater than or equal to 18 years at the time of enrollment;
  • Able to provide written informed consent;
  • Willing and able to complete study procedures;

    • Must be right-handed to participate in the Functional Magnetic Resonance Imaging (fMRI) technical development sub-study.;

Fatigued Participants

-In addition to the above, must experience fatigue for more than a month.


Exclusion from study entry:

  • Not fluent in English;
  • Have medical health issues that create additional and substantial adverse risks related to study procedures. Medical examples are the acute complications of medical disease, such as unstable hypertension, diabetic ketoacidosis, symptomatic hyperthyroidism, and unstable angina.
  • Have a psychiatric condition that prevents participant from being able to reliably report the fatigue experience (e.g., a psychotic disorder with severely disorganized thinking);
  • Current substance use disorder within the last five years as diagnosed on the Structured Clinical Interview for DSM-5 (SCID-5) or positive urine toxicology results at enrollment and before Stage 2. Prior marijuana use within the past five years will not be an exclusion;
  • Categorized as a high-risk drinker (greater than or equal to 5 drinks/day and greater than or equal to 15 drinks/week for men, greater than or equal to 4 drinks per day and greater than or equal to 8 drinks per week for women). ( Dietary Guidelines for Americans 2015-2020", U.S. Department of Health and Human Services and U.S. Department of Agriculture).
  • NIH Employees
  • Pregnant or lactating women
  • Ongoing medical condition that is deemed by the Principal Investigator to interfere with the conduct or assessment of the study or safety of the participant.

Exclusion from Stage 2 Tests:

  • fMRI Technical Development Sub-Study

    • Implanted cardiac pacemakers, metal aneurysm clips;
    • Broken bones repaired with metal pins, screws, rods, plates;
    • Prosthetic eye implants,
    • Transdermal medications or infusion pumps;
    • Bullet fragments or other metal pieces in body from old wounds;
    • Significant work exposure to metal particles;
    • Clinically relevant claustrophobia;
    • Unable to lie comfortably on back for up to 4 hours;
    • Left-handed
  • EEfRT and Stroop Test

    • Severe essential hand tremor or severe hand pain (e.g., severe arthritis or severe carpel tunnel) that makes it difficult to perform rapid keyboard presses will be an exclusion from the EEfRT and Stroop Test.
    • Color-blindness, verified by scoring greater than or equal to 14 on the Ishihara card test, will exclude a participant from taking the Stroop test. The Ishihara card test will be administered only if the participant states he or she is color-blind.
  • Tilt Table Test

    --Beta blocker medications

  • CPET

    • Any neuromuscular conditions (e.g., multiple sclerosis, Parkinson s disease) with significant mobility impairment that prohibits treadmill or bike performance, or any medical condition (e.g., congestive heart failure, coronary artery disease, chronic obstructive pulmonary disease [COPD], severe osteoarthritis and poorly controlled asthma) that would make it risky for the participant to exercise (e.g., exercise-induced angina and asthma), will exclude a participant from the CPET.
