Long-Term Sequelae in Young Convalescent COVID-19 Patients

Area of Science:

• Neurology
• Infectious Diseases
• Neuropsychology

Background:

• The acute effects of SARS-CoV-2 infection are known, but long-term central nervous system complications remain largely uncharacterized.
• Post-viral neuropsychological sequelae, commonly termed 'brain fog,' are increasingly reported in COVID-19 survivors.
• Cognitive difficulties impact daily functioning, including workplace engagement.

Observation:

• This study details three patients under 60 evaluated at a Memory Disorders Clinic after SARS-CoV-2 infection.
• Characterization of long-term neuropsychological symptoms and cognitive deficits following COVID-19.
• Analysis of neuropsychological test results and brain MRI findings in affected individuals.

Findings:

• Patients presented with persistent inattention, executive dysfunction, and memory impairment.
• Neuropsychological testing revealed objective cognitive deficits.
• Brain MRI findings were evaluated in conjunction with clinical and cognitive assessments.

Implications:

• Understanding the long-term neurological impact of COVID-19 is crucial for patient care.
• Further research is needed to elucidate the mechanisms behind 'brain fog' and other cognitive sequelae.
• This characterization aids in diagnosing and managing persistent post-COVID-19 neurological conditions.
