The current study looked at data from 921 adults hospitalized at Boston Medical Center for Covid-19 from April 15 to July 1, met 74 requiring examination by a neurologist. The patients involved in the study were average age of 64 jare, en 47 already had a history of neurologic disease.
Focusing on patients with existing neurological manifestations, the researchers found that 18 had been admitted to the hospital due to strokes after contracting Covid-19, 15 had seizures and 26 had a form of brain dysfunction causing confusion and delirium. Another seven had movement disorders, and three patients had suffered traumatic brain injuries related to falls at home after coming down with Covid-19.
Ten of the people in the study group died, from causes including multi-organ failure. Many of the survivors who had entered the hospital with a mild neurological disability were discharged with moderately severe disability, the study found.
A study in a low-income community
One important aspect of the study was in portraying how Covid-19 and its aftermath impact low-income areas and communities of color, said Anand, who is a member of the American Academy of Neurology.
Boston Medical Center, which is located in the city’s South End, serves a neighborhood where over half of patients live in households with income less than $ 25,000, two-thirds are racial or ethnic minorities and 72% of hospital visits are by low-income or elderly patients who rely on government-provided insurance coverage.
“We were in the unique position of caring for patients who were disproportionately affected by Covid-19 and just wanted to paint a fuller picture of what the neurologic complications are in this critical set of patients,” Anand said.
During the time covered by the study, the hospital had the second-highest Covid-19 case count of any hospital in Massachusetts, a state that itself was third in the nation for overall cases and cases per capita.
“Neurological complications of Covid-19 may arise from direct effects of the virus, but are more typically a reflection of the nervous system’s response to the infection,” het dr. Orly Avitzur, the president-elect of the American Academy of Neurology and editor in chief of the organization’s Brain & Life magazine, via e-pos. She was not involved in the study.
Byvoorbeeld, low oxygen levels, which are common in Covid-19 patients, can cause encephalopathy, or brain damage that could prove permanent, verduidelik sy. And those with severe cases of Covid-19 cases can have surges of immune signaling proteins called cytokines, which can cause alteration of consciousness of confusion with effects lasting months, if not longer, after the initial infection.
Avitzur noted that the study at Boston Medical Center only analyzed neurological patients during their hospitalization or 30 days prior to admission, so future research is required to assess the long-term consequences of these effects on Covid-19 survivors.
“With nine months into this pandemic, we cannot yet predict the course of the long-term effects,” sy het gese. “We are likely to be gathering these data for years to come.”
She cited a similar studeer published by Spanish researchers in August showing that
57% of those with Covid-19 experienced at least one form of neurologic symptom
, including myalgias
, headaches and disorders of consciousness
Disorders that change you as a person
Of the 64 survivors with neurological complications that were discharged from the hospital in the Boston study, 27 of them returned home. Sommige 20 patients required ongoing care at skilled nursing facilities, insluitend 11 who had been living at home prior to hospitalization. Another nine were sent to acute rehab centers, three needed care at long-term acute hospitals and five patients entered hospice care.
“A lot of patients had Covid-caused complications of critical illness systemically,” Anand said. “People’s journey is not over when they leave the hospital.”
And it’s unclear how long these alterations to their lives might last.
“Beyond just the question of surviving or not surviving, there’s this kind of vast grey area of when do you get to be the person you were before you were ill?” Anand said.
It’s unclear whether some will get their life as they knew it back again.
“For so many people, that’s just as important as the question of survival or not,” sy het gese.
