Neuropsychiatric Impairments

Long COVID Study On Neuropsychiatric Impairment

Investigating Neuropsychiatric Impairments In Long COVID: A Groundbreaking Study


In a recent YouTube video, Dr. Misha Kogan, an expert in Integrative Medicine, introduced Dr. Alba Azola, Director of Long COVID at Johns Hopkins and an Assistant Professor in the Department of Physical Medicine and Rehabilitation. Dr. Azola shared exciting news about a new study she is leading, focusing on the neuropsychiatric effects of long COVID. The study aims to explore the role of blood-brain barrier disruption and its contribution to inflammatory states in patients experiencing lingering symptoms. Let’s dive into the details of this groundbreaking research.

Understanding the Study

Dr. Azola’s study is a collaborative effort between the Department of Neurology and Infectious Disease. The researchers are leveraging techniques previously employed to examine Neuropsychiatric impairments post-HIV and applying them to long COVID patients. The study focuses on individuals experiencing Neuropsychiatric sequelae, which includes cognitive impairments, depression, and anxiety. The primary hypothesis centers around the disruption of the blood-brain barrier, leading to the migration of immune cells into the brain and subsequent inflammation.

The study involves two visits. During the first visit, participants undergo blood work, including specific tests for cytokines not commercially available. These tests help identify biomarkers associated with blood-brain barrier permeability and inflammatory states. Additionally, a psychologist administers an extensive cognitive assessment to assess cognitive function, depression, and anxiety levels. The second visit involves an MRI study at the Kennedy Krieger Institute (KKI) to quantify the disruption of the blood-brain barrier.

Comparing Patient Groups

The study aims to compare two groups of patients: those with long COVID symptoms and those who have recovered from COVID-19 and do not exhibit lingering Neuropsychiatric impairments. By examining these two groups, researchers can better understand the specific role of blood-brain barrier disruption in long COVID patients.

Inflammatory Marker Testing

To assess blood-brain barrier permeability and inflammation, the study measures various inflammatory markers. These markers include CCL2, CXCL12, VEGF, TNF-Alpha, IL-6, CCL19, Mig, and CXCL9. The extensive list of tests provides a comprehensive understanding of the biomarkers associated with long COVID and its Neuropsychiatric sequelae.

Patient Participation and Sponsorship

Patient participation is crucial for the success of this study. The study is fully sponsored by the National Institutes of Health (NIH), ensuring that patients do not incur any costs associated with the blood work, MRI, or other assessments. By participating, patients contribute to expanding knowledge and understanding of long COVID, ultimately paving the way for targeted treatments and improved patient care.

Study Logistics and Progress

The study visits take place at the Main Campus and KKI. Patients receive comprehensive neuropsychological assessments and MRI scans to evaluate brain health. The research team has already begun recruiting patients and anticipates enrolling three to four patients per week. Although the study was funded in May, the research timeline was delayed, but efforts are underway to accelerate recruitment and progress.


Dr. Alba Azola’s study investigating the neuropsychiatric impairments in long COVID patients marks an important step towards understanding the underlying mechanisms and potential treatments for these lingering symptoms. By exploring the disruption of the blood-brain barrier and its role in inflammatory states, researchers aim to provide insights into the pathophysiology of long COVID. Patient participation is vital to the success of the study, and those involved will contribute to advancing medical knowledge and improving patient outcomes.
