In June, researchers at La Trobe University found 'toxic clumps of protein', or amyloid assemblies, appearing in the brain after a COVID-19 infection appeared to be similar to those found in Alzheimer's disease and dementia. 'The good news is that the study shows children are not as severely affected on the whole and tend to recovery over a finite time,' he says. Two years after having COVID-19, diagnoses of brain fog, dementia and epilepsy are more common than after other respiratory infections, according to the recent study by the University of Oxford.īut anxiety and depression are no more likely in adults or children two years on, the research published in the Lancet Psychiatry found. 'But there is a spectrum - some are mild and their change in cognition is barely noticeable whilst others are unable to work at all.'Īustralia's Health Department also notes one of the most common neurological symptoms is, 'difficulty concentrating … what's often called brain fog, where people just are unable to think clearly'. Many patients come to see us because they are unable to perform their usual activities including work and study due to their post-COVID neurological effects,' he says. Respiratory Physician Anthony Byrne says brain fog is one of the most common symptoms he's seen-and he works in Australia's first long COVID clinic, at St Vincent's Hospital in Sydney. While brain fog isn't a medical term, it's generally used for certain symptoms that can affect your ability to think.

Yes, some people develop neurological symptoms after being infected. Here's what we know about brain fog and how COVID-19 affects your brain. However, the recent study helps shed light on the risk of neurological disorders after an infection. More than 596 million COVID-19 cases have been recorded globally - including nearly 10 million in Australia - and many of the long-term impacts are yet to be seen. COVID-19 is linked to an increased risk of developing brain fog and dementia after an infection, according to a recent medical study.
