A new study led by the Stanford University School of Medicine is offering new insights into long COVID-19 symptoms, with evidence suggesting the brain fog experienced by some patients bears striking similarities to the cognitive impairment seen in cancer patients following chemotherapy.
such as attention, concentration, memory and executive functioning issues that could potentially last two months or longer after mild infection, the researchers say.They say chemotherapy can impair the brain's white matter, regions with insulated nerve fibres that quickly transmit signals with the help of a fatty coating called myelin.
The study's authors say the effect of newer COVID-19 subvariants, such as Omicron, as well as breakthrough infections in vaccinated people, remains to be fully determined. The effects on the brain from a respiratory COVID-19 infection in children and older people also requires more research, they said.
Her team is currently conducting research on medication that could alleviate brain fog after chemotherapy, which she says could prove helpful following a COVID-19 infection.
