Long COVID or Post-acute Sequelae of COVID-19 (PASC): An Overview of Biological Factors That May Contribute to Persistent Symptoms

The study titled “Long COVID or Post-acute Sequelae of COVID-19 (PASC): An Overview of Biological Factors That May Contribute to Persistent Symptoms” delves into the complexities and potential mechanisms underlying the long-term health consequences of COVID-19, also known as Long COVID or Post-acute sequelae of COVID-19 (PASC). Here’s a detailed summary: Introduction to PASC: PASC refers to a range of persistent symptoms experienced by a subset of patients following acute SARS-CoV-2 infection, lasting for many months. The symptoms vary widely among individuals, suggesting the involvement of different underlying biological factors which are not mutually exclusive. The paper explores various mechanisms,…

Microstructural brain abnormalities, fatigue, and cognitive dysfunction after mild COVID-19

The study titled “Microstructural brain abnormalities, fatigue, and cognitive dysfunction after mild COVID-19” aimed to investigate cognitive dysfunction and brain changes in individuals who experienced mild SARS-CoV-2 infection. A total of 97 unvaccinated individuals, with a median age of 41 years, were examined approximately 79 days (median) after their COVID-19 diagnosis. The participants underwent semi-structured interviews, neurological examinations, 3T-MRI scans, and neuropsychological assessments. The study excluded individuals with current or a history of psychiatric symptoms, including anxiety and depression, to avoid biases related to brain changes and cognitive dysfunction associated with these conditions. Key Findings: Conclusions: The study suggests that…

SARS-CoV-2 infection causes dopaminergic neuron senescence

The study “SARS-CoV-2 infection causes dopaminergic neuron senescence” provides critical insights into the impact of COVID-19 on the nervous system, especially regarding dopaminergic (DA) neurons, which are crucial for motor control and reward systems. Here’s a detailed summary: Study Overview: Key Insights and Findings: Conclusions and Implications: The study highlights the vulnerability of DA neurons to SARS-CoV-2 and the resultant cellular senescence, shedding light on the potential neurological complications in COVID-19 patients. The identification of FDA-approved drugs that can mitigate these effects emphasizes the possibility of repurposing existing drugs to manage neurodegenerative symptoms in COVID-19 patients. However, further research and…

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…

Mid and long-term neurological and neuropsychiatric manifestations of post-COVID-19 syndrome: A meta-analysis

The study titled “Mid and long-term neurological and neuropsychiatric manifestations of post-COVID-19 syndrome: A meta-analysis” offers crucial insights into the long-term effects of COVID-19. Here’s a detailed summary: Background: The study addresses the prevalence of neurological and neuropsychiatric symptoms persisting or developing three months after the onset of COVID-19, contributing to the global healthcare burden. It aims to synthesize and quantify these symptoms via meta-analysis​​. Objective and Methods: The study focused on evaluating the prevalence of neurological and neuropsychiatric symptoms three months post-acute COVID-19 infection. It analyzed 18 studies encompassing a total of 10,530 patients, comparing symptoms in hospitalized and…
