During a TGA episode, you can’t form new memories (a condition called anterograde amnesia ), and you have difficulty recalling recent memories (a condition called retrograde amnesia). We did not identify any precipitating events prior to the onset of transient global amnesia.Ĭopyright © 2022 Elsevier Inc. Transient global amnesia (TGA) is a rare medical condition in which you experience a sudden episode of memory loss. In addition to hypertension, individuals with transient global amnesia had similar cardiovascular risk factors as the general population. We found that nearly 50% of patients with transient global amnesia had hyperintense hippocampal brain magnetic resonance imaging lesions. There was no higher incidence of migraine in transient global amnesia patients (13%). Stress and exercise preceded the onset of transient global amnesia only in 13% and 16% of patients, respectively. The incidence of hypertension in patients with transient global amnesia was higher than in the general population. The major pathogenetic theories of TGA (epileptic, thrombotic and migrainous) were investigated through the study of clinical histories and risk factors and the recurrences of. Most lesions were located in the CA1 subfield. Fifty-five patients admitted to hospital for pure transient global amnesia (TGA) were studied and followed up for a period ranging from 12 to 67 months. Of those, 65% had unilateral lesions, 82% were left-sided, and 28% were right-sided. In most cases, transient global amnesia is benign, and the etiology remains unknown. ![]() Hippocampal brain magnetic resonance imaging lesions were detected in 47% of patients with transient global amnesia. Transient global amnesia (TGA) is a fairly common occurrence in patients arriving to the emergency department. quent among patients with opioids as their main toxic agent. The incidence of brain magnetic resonance imaging lesions was analyzed for the coexisting cardiovascular risk factors and precipitating events. abuse worldwide necessitates novel monitoring sources. In this retrospective, an observational study we assessed brain magnetic resonance imaging in 38 consecutive patients with transient global amnesia. ![]() ![]() Magnetic resonance of the brain including diffusion-weighted imaging of patients with transient global amnesia revealed the presence of punctate hyperintense signal abnormalities in the hippocampus.Īnalysis of the presence of hippocampal lesions in brain magnetic resonance imaging in patients with transient global amnesia and the possible influence of additional factors on their appearance. Transient global amnesia is a benign syndrome characterized by a sudden onset loss of anterograde amnesia with full recovery.
