About this study

Official title: Cortical Excitability and Neuropsychological Behavior Changes Following COVID-19 Infection in the Human Brain

The global COVID-19 pandemic has now led to millions of infections worldwide. It produces long-lasting changes in the general physiology of multiple organs, including the brain. Thus, this study aimed to comprehensively understand the cortical excitability and neuropsychological behavior changes in patients following SARS-CoV-2.

Read the detailed description

The global COVID-19 pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has led to millions of infections and deaths worldwide. However, many issues about the nature of some long-term infection-related symptoms have not yet been well clarified.

Several lines of evidence have shown that SARS-CoV-2 can attack multiple organs such as the lungs, heart, kidneys, liver, as well as brain. The pathophysiologic analyses have shown the impact of SARS-CoV-2 on the brain, including the virus-induced neuroinflammation, the immune reactions, and the possible presence of the coronavirus in the central nervous system in the COVID-19 cases. Indeed, patients who recovered from COVID-19 may experience several long-term symptoms related to brain health, such as fatigue, cognitive and attention deficits, anxiety, and depression, which can affect their ability to work or even daily life. Therefore, the neuropsychological behavior changes in patients following SARS-CoV-2 infection remain an ongoing study area.

In parallel, studies have shown that behavioral abnormities in COVID-19 patients are often accompanied by cortical changes. Utilizing magnetic resonance imaging, a more significant reduction in grey matter thickness and tissue contrast in the orbitofrontal cortex and parahippocampal gyrus has been identified. Other studies confirmed impairment of frontoparietal cognitive functions and frontoparietal hypometabolism by 18F-fluoro-2-deoxy-d-glucose positron emission tomography15. In addition, electroencephalogram abnormalities were also seen in patients who survived from COVID-19. In recent decades, transcranial magnetic stimulation (TMS) has been recognized as a promising and noninvasive adjuvant diagnostic tool enabling assessment of the excitatory and inhibitory properties of the motor cortex as well as brain connectivity17,18. However, the evidence of inhibitory or excitatory changes of intracortical networks in patients recovered from COVID-19 is still scarce.

In this study, we aimed to investigate whether deficits in response inhibition and decision-making could be found in patients following mild SARS-CoV-2 infection. Moreover, we also focused on the neurophysiological evaluation of excitability and neurotransmission within the primary motor cortex (M1).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The cortical excitability changes following COVID-19 infection.

    This was assessed by single/paired pulse TMS procedures.

    Measured: January 2023 to March 2023

Secondary outcomes (1)
  1. The neuropsychological behaviors following COVID-19 infection.

    These were assessed by Stop-signal task (SST) and Choice under risk and ambiguity task (CRA).

    Measured: January 2023 to March 2023

Questions about this trial

What is this clinical trial studying?

An observational study of COVID-19, run by RenJi Hospital.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 27 Jul 2023. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Liqun Yang, MD (+86-15921969001, lqyang72721@126.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The cortical excitability changes following COVID-19 infection. (time frame: January 2023 to March 2023). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05961618, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Jul 2023.
