Research Summary:
A recent study published in Brain reveals that individuals suffering from long-term COVID-19 may experience significant cognitive issues for over a year. Conducted during the first wave of the pandemic, the research compared patients with ongoing symptoms to those who had fully recovered. Out of 105 patients, 83 reported long-term neurological symptoms such as memory loss and difficulty concentrating. Common complaints included severe fatigue (82%), headaches (72%), anxiety (58%), limb weakness (57%), insomnia (57%), and depression (46%).
Key Findings:
Key findings indicated that nearly half of those with long COVID had noticeable memory problems, including difficulties with verbal and visual memory. Approximately 27% of patients exhibited significant issues with attention, verbal working memory, processing speed, and verbal fluency. Furthermore, 20% of those affected had severe cognitive impairment. Brain scans revealed that patients with long-term COVID showed noticeable changes in brain structure, particularly in areas associated with memory and attention. These changes were more prevalent in patients who had severe initial infections.
Conclusion:
The study underscores the serious and lasting impact of long-term COVID-19 on cognitive functions. It highlights the importance of recognizing and addressing these long-term symptoms and emphasizes the need for ongoing support and treatment for affected individuals.
