The Norwegian Study of Nervous System Manifestations and Sequelae After COVID-19

Neurologic, neuropsychological and neuropsychiatric symptoms, signs and diagnoses are increasingly being reported in COVID-19 patients. However, the extent and implications of such "NeuroCOVID" involvement, as well as blood and MRI biomarkers for neurological and psychiatric COVID-19-affection and treatments, warrants further studies. The investigator will perform a national study with clinical and biomarker assessments of NeuroCOVID in approximately 150 Norwegian patients, recruited from ongoing COVID-studies in Norway as well as from neurological departments in Norway. The investigator will define the burden of neurological, psychological and psychiatric complications of COVID-19 disease and identify clinical characteristics and biomarkers for both short- and long-term neurological treatment and rehabilitation. Blood samples for biomarker analyses, brain MRI, clinical neurological, neurophysiological and neuropsychological assessments will be performed at 6 and 12 moths after acute disease,
