Motivated Decision-Making and Performance

Overview

This proposal aims to understand the neurobiological mechanisms of fatigue in individuals with Post-Acute Sequelae of SARS-CoV-2 Infection (PASC). This knowledge will eventually provide candidate mechanisms to target with pharmacological intervention and inform rehabilitative care for those individuals suffering from symptoms of fatigue in PASC.

Interventions

  • Behavioral Physical Fatigue
    Participants will perform a physically demanding task (grip force exertion task) repeatedly to induce physical fatigue.

Primary outcome measures

  • Comparison between PASC and HC - difference in mean Assessment Error [Time frame: Baseline, during experimental protocol.]
  • Comparing between PASC and HC - difference in BBB permeability [Time frame: Baseline, during MRI acquisition.]
  • Comparing between PASC and HC - Regions of the brain that are sensitive to Assessment error as a function of disease state [Time frame: Baseline, during experimental protocol.]
  • The modulatory effect of BBB permeability on the relationship between Neural Activity and Effort Assessment [Time frame: Baseline, during experimental protocol and MRI aquisition.]
  • Comparing between PASC and HC - Difference in momentary subjective fatigue ratings [Time frame: Baseline and during fatiguing exertions in the experimental protocol.]
  • Comparing between PASC and HC - Difference in Mean Acceptance Rate of Risky Effort Options between rested/baseline and fatigue choices [Time frame: Baseline and during fatiguing exertions in the experimental protocol.]
  • Comparing between PASC and HC - Regions of the brain encoding a difference in effort cost between rested/baseline and fatigue choices [Time frame: Baseline and during fatiguing exertions in the experimental protocol.]
  • The modulatory effect of BBB permeability on the relationship between Neural Activity and change effort-based decision-making [Time frame: Baseline, fatigueing exertion, and during experimental protocol and MRI aquisition]
  • Comparing between PASC and HC - Difference in mean assessment error as a function of time [Time frame: Data collections at months 0, 3, 6, 12]
  • Comparing between PASC and HC - Difference in momentary subjective fatigue ratings as a function of time [Time frame: Data collections at months 0, 3, 6, 12]

Eligibility criteria

Inclusion criteria

  • Age 18 to 75 years old.
  • Have received a clinical diagnosis of post-acute sequelae of SARS-CoV-2 (PASC)/long COVID syndrome using the criteria specified by Thaweethai, et al., 2023 (JAMA). This symptom checklist provides a score based on the number and severity of symptoms. An individual with a score >12 is classified as having PASC.
  • Currently experiencing Fatigue/Brain Fog as assessed with the Post-COVID symptom checklist and the PedsQL questionnaire.

Exclusion criteria

  • Neurological disorders including, but not limited to, stroke, head injury, epilepsy, seizures, brain tumors, brain surgery, Parkinson's Disease, or any other neuromuscular disease (self-report).
  • Diagnosed history of severe psychiatric diseases such as depression and schizophrenia (self-report).
  • Congestive heart failure.
  • Peripheral artery disease with claudication.
  • Cancer.
  • Pulmonary or renal failure.
  • Unstable angina.
  • Uncontrolled hypertension (more than 190/110 mmHg).
  • Severe aphasia.
  • Orthopedic or pain conditions.
  • Have had exposure to metal or metal implants, due to the hazardous effects of the magnetic field.
  • If on immunomodulatory therapy, they must have been on that therapy for at least 6 months before the start of the study.

Healthy age- and sex-matched controls for PASC - Exclusion criteria: Participants with a history of any of the following will be excluded from the study:

  • Hospitalization due to SARS-CoV-2 infection.
  • Neurological disorders including, but not limited to, stroke, head injury, epilepsy, seizures, brain tumors, brain surgery, Parkinson's Disease, or any other neuromuscular disease (self-report).
  • Diagnosed history of severe psychiatric diseases such as depression and schizophrenia (self-report).
  • Congestive heart failure.
  • Peripheral artery disease with claudication.

Criteria are shown verbatim from the registry (in English). Final eligibility is always assessed by the study center.
