LA doctor identifies case of coronavirus-related psychosis in patient

LOS ANGELES (KABC) -- The physical impacts of COVID-19 are playing out in overcrowded hospitals across Southern California, but there are growing concerns over the mental impacts of the virus.

Research is uncovering cases of severe psychosis tied to coronavirus.

A patient in Los Angeles undergoing care for COVID-19 also developed a severe mental disorder.

"We have a patient presently who is being treated for COVID. And while being treated for COVID has psychosis and has emerged with beliefs that are totally bizarre abnormal," Keck Medicine of USC psychiatrist Dr. Steven Siegel said.

Siegel explained people with psychosis experience thoughts and emotions so impaired, they lose touch with reality.

A man in his 20s in Colorado is confirmed to have the COVID-19 variant that was detected in the United Kingdom, Colorado officials announced Tuesday.

"People believe the police are after them or their families are trying to hurt them," he said.

Individual reports of coronavirus-related psychosis have been documented in medical journals. Some experts suspect the cause could be the body's immune system response or inflammation caused by the disease.

Dr. Charles Casassa is a neurologist at Loma Linda University Health.

"We see symptoms that are related to brain inflammation, which can include confusion and rarely psychosis," he said.

Casassa is studying the effects of COVID-19 on patients with epilepsy and found the virus can cause more seizures.

"We have also found that there are some patients who have no history of seizures before that can subsequently get seizures once infected with COVID," he said.

Research on how COVID-19 affects the brain is still in its early days. How long the psychosis episodes may last and who is vulnerable are all questions that need to be answered. However, Siegel says people need to keep in mind that the condition is very rare.

"This is much more the extreme. An extreme rarity than it is something that I think people need to spend their energy worrying about," Siegel said. "It's not likely to happen."
