Covid-related loss of smell tied to changes in the brain
A study of 73 COVID-19 patients found that loss of smell is associated with significant brain changes, including decreased activity and structural alterations, highlighting the need for further research.
Read original articleA recent study involving 73 adults recovering from COVID-19 has found that those who experienced a loss of smell exhibited significant behavioral, functional, and structural changes in the brain. Conducted in Chile, the research included cognitive assessments, decision-making tasks, and MRI scans, comparing COVID-19 patients to a control group of 27 individuals with other infections. The study revealed that 30.1% of COVID-19 patients reported attention and memory issues, with some experiencing persistent smell impairment. MRI results indicated that loss of smell correlated with decreased brain activity during decision-making, loss of white-matter integrity, and thinning of the outer cerebrum layer. The authors suggest that anosmia could serve as a potential marker for virus-induced neuronal damage and identify individuals at risk for further brain alterations. They emphasize the need for further research to understand the relationship between loss of smell and brain changes, as well as to explore potential treatment targets.
- Loss of smell in COVID-19 patients is linked to brain changes.
- The study involved cognitive testing and MRI scans of 73 COVID-19 patients.
- 30.1% of participants reported attention and memory problems.
- MRI findings showed decreased brain activity and structural changes in those with smell loss.
- Further research is needed to explore the implications of these findings.

Other than a few weeks of feeling tired one time, I've never actually managed to test positive. This is after living in new york for the past four years.
Anyone else had this experience? The only palpable side-effect or long-lasting effect has been increased noise sensitivity, tinitus in one ear seemingly out of nowhere and now I have mild exima which never was an issue in years past.
At the time of my first infection, I was experiencing, like many, a real series of rather difficult life problems as well as major events. I'd say that could be partly to blame, but the COVID definitely diminished my cognitive abilities as well as my memory. I had what is commonly known as mental fog. Here I am, having studied all my life, doing art, design, programming and build many great stuff with passion, speed of execution and a mastery that I'd describe as fairly good, unable to learn anything new and in a permanent state of anxiety. I haven't coded anything good for 3 years now, and my physical health is deteriorating despite my continuous physical and mental efforts.
I forced myself to take a job well below my capabilities which, even so, sometimes poses certain difficulties for me. Telling myself that it would pass and I'd soon be back into it in no time, but it's quite the opposite that's happening. I'm getting dumbed down and sinking around juniors who are now far superior to me in terms of how. Where I live, COVID seems to have been relegated to an old story that no one wants to talk about anymore. The doctors are burnt out and none of the ones I've consulted seem to be able to diagnose long COVID or that sort of thing. I'm beginning to harbor a deep resentment towards this illness, seeing it as the major trigger that screwed up my career. A career that was so difficult to build because I put my know-how ahead of my network.
I've overcome so many hardships in the past. Since 2020, I've been unable to bounce back. I'm simply disgusted.
If you recognize yourself in this profile and impostor syndrome no longer seems so theoretical, I'd really appreciate not feeling lonely.
