COVID-19 Brain Perfusion and Memory Performance Data

78 participants completed neuroimaging and memory tests to explore links between COVID-19 severity, brain perfusion, and cognitive dysfunction. Justin M. Palmer authored this dataset, which includes perfusion MRI measurements and scores from the Mnemonic Similarity Task and Face-Name Associative Memory Exam. The data was last updated on April 10, 2026.

Use Cases

• Analyze relationships between COVID-19 respiratory symptom severity and cortical gray matter perfusion based on participant grouping.
• Model associations between brain perfusion and pattern separation performance based on the Mnemonic Similarity Task scores.
• Compare perfusion differences across arterial territories (anterior, middle, posterior cerebral arteries) based on the MRI mask data.
• Investigate the persistence of perfusion dysfunction over time based on the average 13-month post-infection interval.

Strengths

• Includes data from 78 participants across four distinct COVID-19 severity groups.
• Contains results from two specific memory tests (MST and FNAME) known to be mediated by the hippocampus.
• Perfusion was measured using pseudo-continuous arterial spin labeled (pCASL) MRI, a standardized technique.
• Statistical results are provided, including correlation (r=0.30) and significance (p<0.01) for key relationships.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The 801.1 KB file size suggests a limited scope, likely containing summary results rather than raw participant data.
