Study design
- Researchers performed a cross-sectional analysis of the prevalence of psychiatric and neurologic complications in patients with COVID-19 across multiple centers in United Kingdom. Data were collected through the anonymous online reporting portals of several major neurology and psychiatric associations. Retrospective reporting was allowed.
- Evidence of SARS-CoV-2 infection was defined as:
Confirmed COVID-19 (114 cases) if polymerase chain reaction (PCR) of respiratory samples (eg, nasal or throat swab) or CSF was positive for viral RNA or if serology was positive for anti-SARS-CoV-2 immunoglobulin M (IgM) or immunoglobulin G (IgG).
Probable COVID-19 (6 cases) if a chest radiograph or chest CT was consistent with COVID-19 but PCR and serology were negative or not performed.
Possible COVID-19 (5 cases) if the disease was suspected on clinical grounds by the notifying clinician, but PCR, serology, and chest imaging were negative or not performed.
Outcomes
- Sixty-two percent of patients presented with cerebrovascular events (intracerebral hemorrhage, ischemic stroke, vasculitis, or other). Thirty-one percent of patients presented with altered mental status (AMS), and 5% had peripheral neurologic disorders.
- Of those with AMS, 18% (7 patients) had encephalitis, 23% (9 patients) had unspecified encephalopathy, and 59% (23 patients) had a psychiatric diagnosis as classified by the notifying psychiatrist or neuropsychiatrist. Ten patients (43%) of the 23 patients with neuropsychiatric disorders had new-onset psychosis, while only 2 patients had an exacerbation of a preexisting mental illness.
