Cognitive deficits in people who have recovered from COVID-19

The study titled “Cognitive deficits in people who have recovered from COVID-19” provides vital insights into the long-term cognitive effects observed in individuals who have recovered from COVID-19. This research is particularly relevant due to growing concerns about the cognitive consequences of COVID-19, especially in the context of ‘Long COVID’ symptoms persisting into the chronic phase​​. Key Findings of the Study: Implications: This study highlights the importance of considering cognitive deficits as part of the recovery process from COVID-19, especially for individuals who have been hospitalized. The findings underscore the need for further research to understand the full spectrum of…

Selective visuoconstructional impairment following mild COVID-19 with inflammatory and neuroimaging correlation findings

The study titled “Selective visuoconstructional impairment following mild COVID-19 with inflammatory and neuroimaging correlation findings” provides key insights into the cognitive impacts of COVID-19, particularly in cases classified as mild. Here’s a detailed summary: Background: The study addresses the implications of mild COVID-19 cases, which comprise the majority of infections worldwide. While severe cases of COVID-19 have been linked to neurological and psychiatric consequences, the cognitive impact of mild COVID-19 remains under-researched. The study aimed to investigate adults who had recovered from mild COVID-19 by assessing neuropsychological, ocular, neurological tests, immune markers, and neuroimaging. The research found a specific visuoconstructive…

Post-COVID cognitive deficits at one year are global and associated with elevated brain injury markers and grey matter volume reduction: national prospective study

The study, “Post-COVID cognitive deficits at one year are global and associated with elevated brain injury markers and grey matter volume reduction: national prospective study” provides crucial insights into the long-term cognitive impacts of COVID-19. Here is a detailed summary: Abstract and Background: This prospective national longitudinal study investigated cognitive deficits in 351 hospitalized COVID-19 patients compared to 2,927 matched controls. The research found global cognitive deficits associated with elevated brain injury markers and reduced grey matter volume in the anterior cingulate cortex one year post-hospital admission. The severity of the initial COVID-19 infection, psychiatric symptoms post-acute phase, and history…

Severe COVID-19 is associated with molecular signatures of aging in the human brain

The study “Severe COVID-19 is associated with molecular signatures of aging in the human brain” explores the potential link between severe COVID-19 and accelerated aging in the human brain. Here’s a detailed summary: In summary, this study provides evidence that severe COVID-19 is associated with molecular changes in the brain that resemble aging. The findings highlight the importance of neurological follow-up in recovered COVID-19 patients and underscore the potential long-term impact of severe COVID-19 on cognitive function.

SARS-CoV-2 Spike amyloid fibrils specifically and selectively accelerates amyloid fibril formation of human prion protein and the amyloid β peptide

The study titled “SARS-CoV-2 Spike amyloid fibrils specifically and selectively accelerates amyloid fibril formation of human prion protein and the amyloid β peptide” provides groundbreaking insights into the potential link between COVID-19 and neurodegenerative diseases (NDs). Here’s a detailed summary: Background and Objectives: Methodology: Key Findings: Discussion and Implications: In conclusion, this study sheds new light on the potential role of SARS-CoV-2 spike protein in accelerating amyloid formation related to neurodegenerative diseases, offering a novel avenue for understanding and potentially intervening in the progression of these conditions.

Assessment of Cognitive Function in Patients After COVID-19 Infection

The study “Assessment of Cognitive Function in Patients After COVID-19 Infection” by Jacqueline H. Becker and colleagues, published in JAMA Network Open in 2021, investigates the prevalence and severity of cognitive impairments in COVID-19 survivors. This research is crucial as cognitive dysfunction, often referred to as “brain fog,” has been frequently reported by COVID-19 survivors, yet its extent and association with the severity of the disease were not well understood. Key Findings: This study is significant in understanding the long-term cognitive impacts of COVID-19, underscoring the need for further research and potential rehabilitation strategies for affected individuals.

Long COVID is associated with severe cognitive slowing

Here’s a summary of the study “Long COVID is associated with severe cognitive slowing”: Background and Methods: The study investigated cognitive slowing in post-COVID-19 conditions (PCC). Researchers hypothesized that a common deficit in PCC patients might be generalized cognitive slowing. To test this, 270 patients diagnosed with PCC at two clinics in the UK and Germany performed two web-based cognitive tasks: Simple Reaction Time (SRT) and Number Vigilance Test (NVT). Their performance was compared with two control groups: those who had COVID-19 but did not develop PCC (No-PCC group) and uninfected individuals (No-COVID group)​​. Key Findings: Conclusion and Implications: The…

Brain disorders: Impact of mild SARS-CoV-2 may shrink several parts of the brain

The study, titled “Brain disorders: Impact of mild SARS-CoV-2 may shrink several parts of the brain,” presents significant findings on the neurological impacts of COVID-19, particularly in cases of mild infection. Key points include: These findings underscore the necessity for continued research and healthcare support for individuals affected by COVID-19, especially those experiencing long-term neurological and mental health effects.
