Some COVID-19 patients have developed psychiatric symptoms — including psychosis — in the months after getting the disease, according to researchers.
One study published by Lancet found 13% of roughly 200,000 observed COVID-19 patients developed a psychiatric or neurological symptom such as mood disorders, strokes and dementia six months after contracting the disease, Business Insider reported.
Of that group, a smaller portion experienced psychosis, a severe mental disorder in which patients become detached from reality.
“Psychosis is one of medicine’s big enigmas,” Jonathan Rogers, a researcher in the University College London Division of Psychiatry specializing in neuropsychiatric disorders, told Business Insider. “We have a fairly poor understanding of what causes it and how it develops.”
Scientists speculate the stress from the coronavirus and an autoimmune reaction that leads to inflammation in the brain could trigger psychosis.
