Mid and long-term neurological and neuropsychiatric manifestations of post-COVID-19 syndrome: A meta-analysis

•Question: How commonly are neurological and neuropsychiatric symptoms reported three months or more after acute COVID-19 onset in adults?•Findings: In a meta-analysis of 18 studies encompassing 10,530 patients (hospitalised and non-hospitalised), overall prevalence for neurological symptoms three months after COVID-19 onset was: fatigue (37%), brain fog (32%), memory issues (28%), attention disorder (22%), myalgia (17%), anosmia (12%), dysgeusia (10%), and headache (15%). The prevalence of neuropsychiatric symptoms was sleep disturbances (31%), anxiety (23%), and depression (17%).•Meaning: Given the high prevalence of neurological and neuropsychiatric post-COVID-19 syndrome, randomised controlled trials are necessary to develop intervention strategy to reduce disease burden.
