News Release 8-Jul-2026 Eye problems after COVID-19 can now be explained https://www.eurekalert.org/news-releases/1134768 "The impaired pupil function was furthermore linked to headaches, difficulty reading text & in focusing the eyes" It would be interesting to know how many had general fatigue, PEM, etc. People with ME/CFS can suffer from eye problems.

Eye problems after COVID-19 can now be explained

Mild COVID-19 can cause severe and long-lasting eye problems, according to a study from Linköping University, Sweden. The study also explains why it has been difficult for sufferers to get help: the abnormal eye behaviour cannot be detected by standard methods. The researchers have developed a diagnostic model to detect COVID-related eye problems.

Wearable Heart Rate Variability Monitoring, Autonomic Dysfunction and Post-exertional Malaise in Long COVID: An Observational Study - Sports Medicine

Objectives Patients with long coronavirus disease (COVID) experience disabling fatigue, autonomic dysfunction, reduced exercise capacity and post-exertional malaise (PEM). Heart rate variability (HRV) can evaluate autonomic function and monitor overexertion, potentially helping to mitigate PEM. This study aimed to use continuous multi-day HRV recordings to monitor overexertion and study autonomic function in long COVID. Method Heart rate and HRV were continuously measured in 121 patients with lo

Even if a complete neuron doesn't die, if a huge chunk of the synapses are destroyed, whatever that neuron was doing before, it's doing a fraction afterwards: a measurable, consistent, and symptom-correlated loss of dopamine nerve terminals averaging 18 percent across the long COVID group. with localized damage to areas that match Long COVID symptoms: “In other illnesses this magnitude of loss is associated with symptoms: loss in one region is associated with trouble with motivational energy problems, loss in another region is associated with some slowness of movement, and loss in a third region is associated with memory trouble.” in short, the terminals are gone, the loss is measurable, and it correlates with the symptoms patients have been reporting for years. https://tech-paper.com/scientists-finally-have-a-biological-explanation-for-why-long-covid-patients-lose-motivation-and-cant-think-clearly-they-scanned-their-brains-and-found-the-dopamine-system-was-physically-damaged/ #neuroscience #neurology #science #LongCOVID #PASC #health

Long COVID symptoms linked to measurable damage in the brain's dopamine system

A recent study provides evidence that people experiencing long COVID show a measurable reduction in the brain’s dopamine-releasing neurons. These physical changes tend to be associated with persistent symptoms like apathy, memory problems, and slowed physical movements.

Researchers tested undergrads while measuring brain blood flows. Their brain scans looked like people in their 60s: previously infected students exhibited distinct prefrontal haemodynamic patterns during cognitive engagement, reminiscent of those observed in adults four decades older, and this appeared to be especially true if they reported experiencing brain fog due to COVID-19. Over a third of them showed objective cognitive impairment: 37.33 % of participants who reported previously having COVID-19 displayed objective cognitive impairment [...] (assessed via computerised testing), And neuron death is irreversible: This may indicate microglial hyperactivation, theoretically driven by elevated oxidative stress from dysfunctional mitochondria—a possible contributor to cell death and cognitive impairment https://www.sciencedirect.com/science/article/pii/S0889159124007311 h/t @PatrickWirth@mstdn.ca #COVID #SARSCoV2 #LongCOVID #COVID19 #BrainFog #PASC
