Clouding of consciousness

Long Covid ‘brain fog’ may be due to leaky blood-brain barrier, study finds. If barrier controlling substances entering and exiting brain is off balance, it can drive changes in neural function.

Understanding the Clouding of Consciousness

The clouding of consciousness, often referred to as "brain fog," is a common symptom experienced by individuals with Long Covid. Recent studies have found that this cognitive impairment may be linked to a leaky blood-brain barrier. When the barrier that controls substances entering and exiting the brain is disrupted, it can lead to changes in neural function, resulting in symptoms such as confusion, difficulty concentrating, and memory problems.

Implications of a Leaky Blood-Brain Barrier

The findings of this study shed light on the potential mechanisms underlying the clouding of consciousness in Long Covid patients. By understanding the role of the blood-brain barrier in neural function, researchers may be able to develop targeted treatments to alleviate cognitive symptoms and improve the overall quality of life for individuals struggling with brain fog.
