The identification of this trigger of TGA may help the clinician in his etiological research.Īt the end of 2019, in China, a cluster of viral pneumonia cases developed, later identified as COVID-19 (Coronavirus disease 2019). Yet, numerous confounding factors cannot be tackled with this approach, and causality cannot be ascertained. Cerebrovascular, inflammatory, or migrainous mechanisms may underlie this association. Our analysis of COVID-19 vaccines-related TGA reports shows significant disproportionality. With an IC025 > 0, COVID-19 vaccines showed a significant ROR (5.1 95%CI 4.4–6.0). Of all TGA cases, 289 were associated with a COVID-19 vaccine, representing the most frequent association. A positive lower end of the 95% CI of the IC (IC025) is used to statistically detect a signal.
Disproportionality analysis relied on the Reporting Odds Ratio (ROR) with its 95% Confidence Interval (CI) and the Information Component (IC). We queried the World Health Organization VigiBase ® for all reports of “Transient global amnesia”, up to 6 December 2021. We aimed to investigate the potential link of TGA with COVID-19 vaccines. TGA is characterized by sudden onset of anterograde amnesia with preservation of other cognitive functions and resolution within 24 h. As their safety continues to be monitored, cases of transient global amnesia (TGA) following mRNA vaccination with elasomeran have been reported.

There is a long list of conditions that can cause amnesia. It is usually temporary, but can be permanent in some situations. It is often a symptom of another condition.
People who have amnesia might also be confused and have trouble learning anything new.īut most people with amnesia still remember who they are, and can often remember events from their childhood.Īmnesia is not a medical condition on its own, but a description of an experience. People with amnesia can struggle to form new memories or remember recent events or experiences.
