A family history of TGA was identified in 12 individuals (1.3%) with a single episode of TGA and 4 individuals (2.8%) with recurrent episodes of TGA. Acute and subacute temporal lobe abnormalities on results of magnetic resonance imaging were seen rarely and did not require intervention. There were no electroencephalographic findings associated with increased risk of TGA recurrence. 001), and a family history of migraine in 167 individuals (18.5%) with a single episode of TGA and 44 individuals (30.8%) with recurrent episodes of TGA (P =. There was a personal history of migraine in 180 individuals (20.0%) with a single episode of TGA and 52 individuals (36.4%) with recurrent episodes of TGA (P <. Since the first description, dating back over 60 years, several cases have beenreported in the literature. The mean (SD) age at first episode of TGA was 65.2 (10.0) years for individuals with a single episode vs 58.8 (10.3) years for those with recurrent episodes (P <. Transient global amnesia (TGA) is a clinical syndrome characterized by the sudden onset of a temporary memory disorder with a profound anterograde amnesia and a variable impairment of the past memory. The number of recurrences ranged from 1 to 9, with 137 individuals (95.8%) having 3 or fewer recurrences. The 2 groups were similar in age at inclusion, sex, identifiable triggers, and duration of anterograde amnesia. A total of 901 patients (86.3%) had a single episode of TGA and 143 (13.7%) had recurrent episodes of TGA. Of 1044 included patients, 575 (55.1%) were male, and the mean (SD) age at inclusion was 75.0 (11.5) years. The main outcome measure was TGA recurrence. A total of 1491 cases were reviewed and 1044 met diagnostic inclusion criteria for TGA, with the remainder excluded owing to indeterminate or alternate diagnoses or limited information available in the medical record.ĭemographics, precipitating factors, migraine history, imaging and electrodiagnostic findings, and family history of TGA were collected. This retrospective cohort study involved medical record review of patients with isolated or recurrent TGA presenting to the Mayo Clinic in Rochester, Minnesota, between August 1, 1992, and February 28, 2018. To examine risk factors for the recurrence of TGA. However, recurrence rates vary considerably among studies and there are no known risk factors for TGA. If you have a treatable cause of amnesia, then treatment might allow you to regain your memory.īut if you have ongoing amnesia, then apart from treating whatever is causing it, you will need to developing strategies to improve your memory.Transient global amnesia (TGA) is usually considered a benign event with a low recurrence rate. take images of your brain to look for damage.take a blood test to check for infection or vitamin deficiencies.Your doctor will talk to you and examine you.
