1
Sub cohort 1: Participants in the WHO NOR Solidarity multicenter trial on the efficacy of different anti-viral drugs in SARS CoV-2 infected patients. Eligibility: consenting adults (age ≥18) hospitalized with definite COVID-19 included in the WHO COVID-19 Study. Participants invited to join the study will be those who are admitted to a collaborating hospital; no wider recruitment efforts are expected. |
Other: Observation
The study is a multi-center Norwegian prospective observational clinical study of the occurence of neurological, neuropsychological and psychiatric manifestations and sequelae in patients with COVID-19 at 6- and 12-months follow-up. |
2
Sub cohort 2: Patients with COVID-19 and neurological symptoms related to COVID-19 admitted to the Norwegian Departments of Neurology or other relevant Departments (both hospitalized and outpatient visits) and persons with neurological symptoms participating in other COVID-19 studies and not already participating in the WHO NOR Solidarity multicenter trial. |
Other: Observation
The study is a multi-center Norwegian prospective observational clinical study of the occurence of neurological, neuropsychological and psychiatric manifestations and sequelae in patients with COVID-19 at 6- and 12-months follow-up. |

Sampling Method: | Non-Probability Sample |
Sub cohort 1: Participants in the WHO NOR Solidarity multi-center trial on the efficacy of different anti-viral drugs in SARS CoV-2 infected patients.
Sub cohort 2: Patients with COVID-19 and new neurological, neuropsychological or neuropsychiatric symptoms and/or signs admitted to the Norwegian Departments of Neurology or other relevant Departments (both hospitalized and outpatient visits) or participants from other COVID-19 studies than the NOR Solidarity Study.
Number of participants: Based on the number of included participants in the NOR Solidarity trial and the number of infected individuals we are planning to include 150 participants in the NeuroCOVID-19 study.
Sub cohort 1:
Inclusion Criteria:
- Consenting adults (age ≥18 years) hospitalized with definite COVID-19 included in the WHO: The NOR Solidarity multicenter trial on the efficacy of different anti-viral drugs in SARS CoV-2 infected patients and willingness to participate in the NeuroCOVID study.
Exclusion Criteria:
- If still alive, no willingness and ability to participate in all follow-up examinations.
Sub cohort 2:
Inclusion Criteria:
- Consenting adults (age ≥18 years) with COVID-19 and new neurological, neuropsychological or neuropsychiatric symptoms and/or signs or participants from other COVID-19 studies than the NOR Solidary Study.
Exclusion Criteria:
- If still alive, no willingness and ability to participate in all follow-up examinations.
All participants in both sub cohorts will after the visit by neurologists be assessed by neuropsychologists and psychiatrist at 6- and 12-month follow-up if the following criteria are fulfilled:
- Sufficient Norwegian or English speaking in order to fulfill the tests.
- MoCA score > 18.
- Hospital has C-L psychiatrist/neuropsychologists that participate in the study or collaborate with C-L psychiatrist/psychiatrist/clinical psychologists at nearby hospitals.
