![]() ![]() Our findings indicate that having an episode of TGA does not increase the risk of subsequent cerebrovascular events, seizures, or cognitive impairment.Ĭopyright © 2016 Mayo Foundation for Medical Education and Research. Modified Rankin scale and death rates at last follow-up were also similar between both groups. The TGA recurrence occurred in 5.4% of patients after a median interval of 4.21 years (interquartile range, 2.82-8.44). References Diffusion-Weighted Imaging for the Differential Diagnosis of Disorders Affecting the Hippocampus - Cerebrovasc Dis 2012 33:104115 - DOI: 10. beaches should be regarded merely as transient littoral sys. There was no statistically significant difference between survival curves for the TGA group and the control group using time to any type of cerebrovascular event (log-rank P=.30), time to seizures event (log-rank P=.55), and time to cognitive impair event (log-rank P=.88) as end points. This case demonstrates that MRI plays a useful role in confirming the clinical diagnosis of transient global amnesia. global dune ecosystems are afflicted with analogous normalised degradation and erosion. Previous migraine was more common in the TGA group (42 patients vs 12 patients P<.001). Prevalence of vascular risk factors and history of seizures were similar between both groups. INTRODUCTION Transient global amnesia (TGA) is a clinical syndrome characterized by the acute onset of anterograde amnesia (the inability to form new memories) 1-3. The mean duration of follow-up was 12 years in both groups (range, 0.07-29.93). Glenn A Tung, MD, FACR Deputy Editor: Janet L Wilterdink, MD Literature review current through: Apr 2023. End points were studied using Kaplan-Meier survival plots and log-rank test.Ī total of 221 patients with TGA were identified and 221 age- and sex-matched controls were included in the analysis. End points were cerebrovascular event (stroke or transient ischemic attack), seizure, or cognitive impairment (mild cognitive impairment or dementia) during follow-up. Transient global amnesia (TGA) is a rare but well-described neurological disorder characterised by an acute self-limited episode of dense anterograde amnesia with retrograde amnesia of variable extent. Transient global amnesia was defined clinically. ![]() To study the long-term risk of cerebrovascular events, seizures, and cognitive impairment in patients with transient global amnesia (TGA).ĭata for all patients diagnosed with possible TGA in Olmsted County, Minnesota, between January 1, 1985, through December 31, 2010, were retrieved from the Rochester Epidemiology Project database. ![]()
