One disease, many faces – typical and atypical presentations of SARS-CoV-2 infection-related COVID-19 disease

This study titled “One disease, many faces – typical and atypical presentations of SARS-CoV-2 infection-related COVID-19 disease” by Philips CA et al., published in the World Journal of Clinical Cases provides a comprehensive review focusing on the various clinical presentations of COVID-19, emphasizing the disease’s multisystem impact and the diverse symptoms beyond the commonly known respiratory manifestations. Abstract Summary: The review acknowledges that while COVID-19 is primarily known for respiratory symptoms, there is significant evidence of a wide range of clinical presentations. This review aims to provide an in-depth analysis of these varied presentations, which is crucial for frontline clinicians…

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…

Assessment and Characterization of COVID-19 Related Cognitive Decline: Results from a Natural Experiment

The study titled “Assessment and Characterization of COVID-19 Related Cognitive Decline: Results from a Natural Experiment” focused on the impact of COVID-19 on cognitive function, particularly in patients with Post-Acute Sequelae of SARS-CoV-2 (PASC) or severe COVID-19. The study used a longitudinal cohort design, comparing cognitive performance in 276 COVID-19 patients with 217 controls across four domains sensitive to neuroinflammation or vascular disease, using data collected both before and after the pandemic began in 2015​​. Key Findings: Study Strengths and Limitations: The study employed the Cog State brief battery test to assess cognitive function, which is sensitive to neuroinflammation and…
