Clinical Trial Summary

The purpose of this study is to investigate the effects of transcutaneous vagus nerve stimulation (t-VNS) on Long Covid symptoms in females and to identify factors influencing susceptibility and recovery-particularly in the cognitive domain, as over 80% of long-haulers experience "brain fog".

Description:

Long COVID is a post-viral illness estimated to affect 10-30% of COVID-19 patients. Post-COVID symptoms can last for months and affect multiple organs. Major risk factors of long COVID include the female sex and pre-existing anxiety/depression. Because women already have higher rates of anxiety/depression, the combined risks could exacerbate their susceptibility. Based on the rationale that long COVID symptoms significantly overlap with functions of the vagus nerve, which serves as a conduit between the brain and body, the investigators propose to use non-invasive transcutaneous vagus nerve stimulation (t-VNS) as a novel treatment for long COVID in 20 female participants. This pilot study will utilize a holistic approach by integrating neuromodulation, neuroimaging, genetics, blood biomarkers, behavioral assessments, and wearable technology to examine the effects of VNS therapy on post COVID-19 symptoms and to identify factors that influence susceptibility and recovery, particularly in the cognitive domain, as over 80% of long-haulers report experiencing "brain fog" (i.e., cognitive disruptions).

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in Flanker Inhibitory Control and Attention Test (Flanker) scores	Flanker is a non-verbal NIH Toolbox Cognition Battery assessment that measures both a participant's attention and inhibitory control.	At baseline, at week 3, and at week 7
Primary	Change in Picture Sequence Memory Test (PSMT) scores	PSMT is a non-verbal NIH Toolbox Cognition Battery assessment that measures a participant's episodic memory.	At baseline, at week 3, and at week 7
Primary	Change in Dimensional Change Card Sort Test (DCCS) scores	DCCS is a non-verbal NIH Toolbox Cognition Battery assessment that measures a participant's executive functioning.	At baseline, at week 3, and at week 7
Primary	Change in Pattern Comparison Processing Speed scores	Pattern Comparison Processing Speed is a non-verbal NIH Toolbox Cognition Battery assessment that measures a participant's processing speed.	At baseline, at week 3, and at week 7
Primary	Change in List Sorting Working Memory scores	List Sorting Working Memory is an oral NIH Toolbox Cognition Battery assessment that measures a participant's working memory.	At baseline, at week 3, and at week 7
Secondary	Change in Magnetic Resonance Imaging (MRI)	MRI scans will be acquired on a Siemens Magnetom Verio 3T Scanner at Casa Colina Imaging Center to assess structural changes.	At baseline and at week 3
Secondary	Change in resting state Electroencephalograph (EEG) signals	Using a 64-channel EEG system, we will perform resting-state EEG recordings to assess power spectral density changes.	At baseline and at week 3
Secondary	Change in blood marker levels	Blood markers related to COVID-19, inflammation, brain injury, and neuroplasticity will be analyzed using the Ella automated immunoassay system.	At baseline and at week 3
Secondary	Change in BURNS Anxiety Inventory scores	The BURNS Anxiety Inventory is a self-reported rating scale that measures anxiety symptoms.	At baseline, at week 3, and at week 7
Secondary	Change in Becks Depression Inventory (BDI) scores	The BDI is a self-reported rating inventory that measures characteristic attitudes and symptoms of depression.	At baseline, at week 3, and at week 7
Secondary	Change in PROMIS Sleep Disturbance scores	The PROMIS Sleep Disturbance (8b) is a self-reported measure for perception of sleep quality, depth of sleep, satisfaction with sleep, and perception of difficulty getting and staying asleep.	At baseline, at week 3, and at week 7
Secondary	Change in Fatigue Severity Scale scores	The Fatigue Severity Scale is a self-reported 9-item scale which measures the severity of fatigue and its effect on a person's activities and lifestyle in patients with a variety of disorders.	At baseline, at week 3, and at week 7
Secondary	Change in Sniffin' Sticks olfactory performance	The Sniffin' Sticks test (Burghardt®, Wedel, Germany) assesses odor threshold, odor discrimination, and odor identification.	At baseline, at week 3, and at week 7
