White matter changes in recovered COVID-19 patients: insights from DTI, DKI, and NODDI metrics.

Background: COVID-19 affects not only the respiratory system but also the central nervous system, resulting in symptoms such as anosmia and confusion. Understanding the long-term neurological effects of COVID-19 is critical for comprehensive patient care and management.

Purpose: To study the long-term neurological effects of COVID-19, focusing on changes in white matter structural complexity using advanced neuroimaging techniques.
