NeuroEVs – Marker for Stress and Recovery
Proprietary test measuring brain-related vesicles to provide insights into stress and recovery.
Leaky brain? Biological traces of stress in the blood
Prolonged stress not only affects how we feel – it can also leave marks on the body.
Recent research indicates that the brain's supporting cells, astrocytes, under stress can release small signaling carriers into the blood. These are called NeuroEVs and can provide insight into how the brain reacts and recovers after stress.
Stress-related mental health issues, such as burnout syndrome, have long been some of the most common causes of sick leave in Sweden. Burnout can affect people of all ages, and symptoms – fatigue, reduced concentration, and memory problems – can linger long after the acute stress has subsided.
To understand what happens in the brain during prolonged stress, objective measures are needed. This is where NeuroEVs come in as a new way to study the brain's response to stress and recovery - a new tool to use in the toolbox.
Astrocytes communicate with surrounding cells by releasing small extracellular vesicles, known as NeuroEVs. These can provide clues about how the brain is affected during stress and burnout.
What are NeuroEVs?
NeuroEVs are extracellular vesicles released from brain cells, primarily astrocytes.
They function as the body's own messengers, capable of transporting biological information between cells.
In the case of prolonged stress, research has shown that these vesicles can increase in the blood, reflecting changes in brain activity.
Research has shown that levels of NeuroEVs in the blood increase in:
These findings suggest that NeuroEVs may be a promising biological marker for how the brain is affected during chronic stress and how recovery progresses over time.
FBMLabs NeuroEV analysis
FBMLab has developed and refined methods to measure brain-related vesicles with high precision.
Supported by scientific publications, we offer the NeuroEV analysis – a tool to monitor individual changes in the brain's stress response over time.
The analysis is based on:
Standardized blood testing for safe and easy sampling
Flow cytometric detection of astrocyte-derived vesicles
Advanced data processing and reporting of individual profiles
How it works
Free initial consultation – we go through the analysis, and you have the opportunity to ask questions
Sampling – conducted via a regular blood test at one of our sampling sites.
Analysis – samples are analyzed at FBMLab
Results – a detailed report is delivered within approximately 7 days.
The report shows your NeuroEV levels and any trends. For the best overall picture, follow-up is recommended every 6 months.
Medical follow-up
If your levels are elevated, a medical evaluation is recommended via our partner NEM Health (Nordic Executive Medicine). Contact information can be found in your report.
