"COVID-19 does not just affect the respiratory system, but also significantly
alters the brain in people who have fully recovered from the infectious
disease, highlighting the long-term neurological impact of the virus.
Researchers from Griffith University’s National Centre for Neuroimmunology and
Emerging Disease (NCNED) used advanced MRI techniques to ascertain the
neurological implications of COVID-19 compared with those who had never been
infected.
The research provided compelling evidence that even in the absence of ongoing
symptoms, prior infection with the virus could leave a measurable imprint on
the brain.
Lead author, Dr Kiran Thapaliya, said: “We used multimodal MRI techniques to
examine both grey and white matter brain regions critical for memory, cognition
and overall brain health and found clear differences across all participant
groups.”
“The unique MRI approach identified significant alterations in brain
neurochemicals, brain signal intensity, and tissue structure not only in
individuals with Long COVID but also in those who considered themselves fully
recovered,” he said.
“The research also reported that altered brain tissue was associated with
symptom severity in individuals with Long COVID, suggesting the virus may leave
a silent, lasting effect on brain health.”
These findings offer vital insights into how COVID 19 affects the central
nervous system and may help explain the cognitive problems, such as memory and
concentration, reported both shortly after infection and months or even years
later."
