Madrid, 2025-03-11 – A multidisciplinary team at the Hospital Clínico san Carlos has discovered a direct correlation between cognitive, cerebral, and immunological alterations in patients suffering from persistent COVID and an increased volume in the choroid plexus. Published in ‘Molecular Psychiatry’, this finding offers new avenues for understanding the long-term effects of the disease.
Understanding the Study on Long COVID and Cognitive Impairment
The research aimed to investigate how alterations in the choroid plexus relate to the cognitive, cerebral, and immunological problems experienced by long COVID patients. These individuals, still experiencing symptoms well after the initial infection, often report cognitive decline. The study seeks to understand the underlying mechanisms of this debilitating condition.
The Role of the Choroid Plexus
The choroid plexus, a crucial brain structure, is responsible for several key functions, including producing cerebrospinal fluid and transporting molecules within the central nervous system. It is also believed to act as an entry point for inflammatory cells into the brain, making it a focal point in studies of persistent COVID, especially since its epithelium is vulnerable to SARS-CoV-2 during the acute phase.
Study Details: Participants and Methodology
The study included 129 patients with persistent COVID who, after an average of 14 months post-infection, continued to exhibit symptoms such as fatigue, sleep and olfactory disturbances, and cognitive difficulties, especially in attention, details processing speed, and episodic memory. A control group of 36 healthy individuals was also included. Participants underwent neuropsychological tests, advanced neuroimaging, and immunological marker analysis.

Key Findings and Expert Insights
According to jordi Matías-Guiu Antem, neurologist at the Hospital Clínico San Carlos and director of the study, the results “have revealed an increase in the volume of the choroid plexus in people with persistent COVID compared to healthy patients in the study. This increase was also associated with cognitive dysfunctions and cerebral changes, both structural and functional.” This suggests a potential link between changes in the choroid plexus and neurological issues in these patients.
This research is part of an ongoing inquiry at the Hospital Clínico San Carlos into the long-term effects of persistent COVID.maría Díez Cirarda,neuropsychologist and lead author of the study,suggests that “the integrity of the choroid plexus could play a relevant role in the pathophysiology of cognitive deficits and brain changes observed in people with persistent COVID.” She adds that “the previously documented function of the choroid plexus in maintaining cerebral homeostasis and regulating the entry of immune cells into the brain supports the presence of neuroinflammatory mechanisms in this disorder.”
The Role of Neuroinflammation
While the exact mechanisms remain unclear, neuroinflammation and immunological mechanisms are believed to play a crucial role in the brain damage observed in patients with persistent COVID. Matías-Guiu Antem concludes, “in our study, the volume of the choroid plexus has been proposed as a marker of neuroinflammation in conditions mediated by the immune system. Neurological involvement is increasingly recognized, but questions remain about the mechanism, and these results are novel as they bring us closer to a potential mechanism that explains this neurological damage.”
Implications for Future Research and Treatment
This revelation not only provides a new way to understand the neurological effects of persistent COVID but also opens doors for future research that could lead to new treatment strategies for patients suffering from long-term sequelae.
Summary of Key Findings
| Finding | Description |
|---|---|
| Increased Choroid Plexus Volume | Patients with persistent COVID showed a larger choroid plexus volume compared to healthy controls. |
| Cognitive Dysfunction | The increased volume was associated with cognitive impairments, including issues with attention and memory. |
| Neuroinflammation | The study suggests that neuroinflammation, mediated by the immune system, plays a important role in these neurological changes. |
Further studies are needed to fully elucidate the mechanisms behind these changes and to develop targeted therapies for individuals experiencing neurological symptoms post-COVID-19.

Frequently asked Questions About Long COVID and the Choroid Plexus
What is the key finding of the recent study on Long COVID and the choroid plexus?
The key finding is that patients with persistent COVID exhibit an increased volume in the choroid plexus compared to healthy individuals. This increased volume is also associated with cognitive dysfunctions and structural/functional cerebral changes, suggesting a link between choroid plexus alterations and neurological issues in long COVID.
What role does the choroid plexus play in Long COVID?
The choroid plexus, responsible for producing cerebrospinal fluid and transporting molecules in the central nervous system, is believed to act as an entry point for inflammatory cells into the brain. In Long COVID,the study suggests that changes in the choroid plexus contribute to neuroinflammation,potentially leading to cognitive deficits and brain changes.
What cognitive impairments were observed in Long COVID patients in this study?
Long COVID patients in the study experienced cognitive difficulties, particularly in attention, details processing speed, and episodic memory. These impairments were associated with the increased volume observed in the choroid plexus.
How does neuroinflammation relate to the neurological symptoms of Long COVID?
Neuroinflammation, which is inflammation within the brain, is believed to play a crucial role in the brain damage observed in patients with persistent COVID. The increased volume of the choroid plexus is proposed as a potential marker of this neuroinflammation, suggesting that the immune system’s response may be contributing to the neurological symptoms.
What are the implications of this study for future treatment of Long COVID?
This study provides a new understanding of the neurological effects of persistent COVID and opens doors for future research. It may lead to the advancement of targeted treatment strategies that address neuroinflammation and protect the integrity of the choroid plexus in patients suffering from long-term sequelae of COVID-19.
How was the study conducted, and who were the participants?
The study included 129 patients with persistent COVID and a control group of 36 healthy individuals. Participants underwent neuropsychological tests, advanced neuroimaging, and immunological marker analysis. The Long COVID patients had been experiencing symptoms for an average of 14 months post-infection.
What is the significance of targeting the choroid plexus in Long COVID research?
Targeting the choroid plexus is significant because of its role in maintaining cerebral homeostasis,regulating the entry of immune cells into the brain,and producing cerebrospinal fluid. Understanding its involvement in Long COVID could provide insights into neuroinflammatory mechanisms and lead to new therapeutic approaches.
While the study focused primarily on the volume of the choroid plexus as a marker of neuroinflammation, it also included immunological marker analysis. Further research is needed to identify more specific biomarkers that could help diagnose and monitor neurological involvement in Long COVID. This is an area of ongoing inquiry by the research team involved.
What are the next steps in researching the link between Long COVID and the choroid plexus?
Next steps include further elucidating the mechanisms behind the observed changes in the choroid plexus and developing targeted therapies for individuals experiencing neurological symptoms post-COVID-19. This may involve more detailed examination of the cerebrospinal fluid and its contents, and also longitudinal studies to track changes over time.
What kind of advanced neuroimaging was used in the study?
While the article simply mentions “advanced neuroimaging,” studies of this type often employ techniques such as magnetic Resonance Imaging (MRI) to assess brain structure and function, and possibly Positron Emission Tomography (PET) to look at metabolic activity. These techniques allow researchers to visualize the choroid plexus and other brain regions in detail.
