While respiratory and cardiac complications have received substantial clinical attention, the neurological and psychiatric sequelae remain inadequately characterized at a global scale. This study consolidates epidemiological data from 2021-2024 spanning multiple countries and regions to establish a comprehensive prevalence map of neurological and psychiatric symptoms in Long COVID populations.

Key findings reveal brain fog (cognitive impairment) as the most prevalent symptom (32-60% across populations, with Colombia reporting 60%), follow...
