INTRODUCTION
The coronavirus disease 2019 (COVID-19) pandemic has caused millions of infections and deaths globally. Post-COVID-19 syndrome, or long COVID is characterized by lingering symptoms such as chronic fatigue, headaches, and sleep disturbances. This study aimed to investigate the correlation between these symptoms and T2-hyperintense white matter lesions detected on magnetic resonance imaging (MRI) of the brain and spine in patients with post-COVID-19 syndrome.

METHODS
This retrospective, single-center study analyzed a sample of 96 patients from Bern University Hospital in Switzerland who presented with suspected post-COVID-19 syndrome between 2020 and 2022. Patients completed self-report questionnaires evaluating fatigue, emotional wellbeing, and daytime sleepiness. Brain and spine MRIs were independently rated by 2 neuroradiologists for T2-hyperintense lesions. The correlation between these lesions and symptoms of fatigue and headache was assessed.

RESULTS
The cohort consisted predominantly of women (73%) with an average age of 46 years. Chronic fatigue (90%), sleep disorders (51%), and headache (57%) were the most prevalent symptoms. The fatigue questionnaires indicated high levels of fatigue. Brain MRI revealed T2-hyperintense lesions in 72% of patients, whereas spine MRI showed these lesions in only 16%. There was no statistically significant correlation between the presence of cerebral T2-hyperintense lesions and symptoms of fatigue (p = 0.815) or headaches (p = 0.178). Similarly, no significant correlation was found when considering numbers of pathological brain lesions (fatigue: p = 0.557; headaches: p = 0.820).

CONCLUSION
While T2-hyperintense lesions are common in patients with post-COVID-19 syndrome, their presence does not correlate significantly with symptoms of fatigue or headaches. These findings suggest that T2-hyperintense brain lesions may not be directly related to the subjective experience of these symptoms. Further research with larger sample sizes and adjustment for potential confounding factors is necessary to better understand the relationship between MRI findings and post-COVID-19 syndrome symptoms.

73% female, 16% hospitalised, 1% intubated. Presenting to neuro clinic. 90% with fatigue, 51% with sleep disorders, 57% with headache, 32% with dizziness.

The most common finding in brain MRI in our study was the presence of T2-hyperintense lesions in subcortical and periventricular areas, which is in line with the current literature. These lesions have previously been reported in patients suffering from persistent fatigue after hospitalization for COVID-19, as well as in those with post-COVID-19 “brain fog”. However, these lesions tend to be frequently encountered in other unrelated settings such as post-infectious and inflammatory conditions

Our findings suggest a need to re-evaluate the role of MRI in managing patients with post-COVID-19 syndrome. The absence of a clear structural correlation with common symptoms such as fatigue and headaches indicates that MRI findings, while useful in excluding structural brain abnormalities, may not provide actionable insights for guiding therapeutic interventions. As such, the nonspecific nature of white matter lesions calls for a cautious approach when attributing patient symptoms to these findings.

While more complex imaging protocols such as fMRI or advanced diffusion techniques may be more sensitive to subtle brain changes, in our experience their application in clinical practice remains limited. Other options, such as detailed clinical assessments and the use of validated questionnaires for symptom tracking, may be a more effective strategy in guiding therapy for patients presenting with post-COVID-19 syndrome (39), than using MRI as a routine follow-up tool. This could shift the focus of treatment strategies from purely neurological investigations to a more multidisciplinary approach including neuropsychiatric, psychological, and rehabilitative care.
