Brain structural and functional damage network localization of COVID-19 survivors

Area of Science:

• Neuroscience
• Neurology
• Medical Imaging

Background:

• Inconsistent findings exist regarding structural and functional brain changes in COVID-19 survivors.
• Research is shifting towards understanding diseases via neural networks rather than discrete brain areas.
• Network-level analysis of COVID-19 neurological deficits remains underexplored.

Purpose of the Study:

• To identify structural and functional impairments in COVID-19 survivors.
• To map these impairments onto a coordinated brain network.
• To bridge the gap in network-level localization of COVID-19-related brain changes.

Main Methods:

• Synthesized data from 19 studies (23 contrasts) involving 703 survivors and 596 controls.
• Utilized connectivity-based mapping to project identified regions onto resting-state fMRI data.
• Reconstructed a coordinated brain network associated with neurological abnormalities.

Main Results:

• Structural and functional alterations in COVID-19 survivors were mapped to a distributed brain network.
• Key affected networks include the default mode and limbic systems.
• Identified common and distinct neural correlates for structural and functional impairments.

Conclusions:

• Elucidates the neuropathology of COVID-19 using a network-based framework.
• Provides insights into the distributed neural correlates of neurological deficits in survivors.
• Supports the development of targeted therapeutic interventions for affected individuals.
