Patients with long COVID-19 in the U.S. report far higher rates of brain fog, depression and cognitive symptoms than patients in countries such as India and Nigeria, according to a large international study led by Northwestern Medicine.
The authors note that higher reported symptom burden in the U.S. may reflect lower stigma and greater access to neurological and mental health care, rather than more severe disease.
People with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) and Long COVID experience a disruption to their brain connectivity during a mentally demanding task.
A UCLA-led research team demonstrated that when human immune enzymes break up the spike protein of the virus behind COVID-19, some resulting fragments have the ability to punch holes in membranes of human immune cells.
Those fragments target and kill specific cells based on their shape — the same types of sentinel cells and killer cells depleted in severe COVID-19.
Fragments of protein from the omicron variant showed less activity against the immune cells, a finding that may account for why it’s less dangerous than other strains.
UC San Diego researchers find older women with both depression and anxiety face a 78% higher risk of long COVID, despite similar infection rates. People experiencing mental health illnesses are vulnerable to other diseases and may have trouble following public health guidelines.
In Ontario, primary care home visits, which help older adults who are homebound or have difficulty getting to a clinic, increased during the 2010s but declined after a 2019 policy change reduced payment incentives and the COVID-19 pandemic began. This study examined how primary care home visits for adults aged 65 years and older changed from 2014 to 2024.
