Global amnesia event8/25/2023 ![]() , The onset of symptoms is sudden and unpredictable. , On examination of TGA patients, no symptoms and signs of neurological deficit are found. Typical features of TGA include anterograde amnesia (from a few to several hours, most often from 4 to 8) accompanied by repetitive questioning and disorientation with respect to time and place, but the preserved ability to recognize oneself and other people. Transient global amnesia (TGA) is a temporary short-term memory loss reversible within 24 hours. Transient Global Amnesia - Risk Factors and Putative Background.

The role of autoimmune thyroiditis in the possible pathogenesis of TGA deserves further investigation. Keywords: Autoimmune thyroiditis, migraine, transient global amnesia, vascular risk factor Key Messages: The putative background of TGA is most likely cerebrovascular. Among comorbidities, autoimmune thyroiditis deserves further investigation with regard to its potential links with TGA. No evidence has been provided for the association between TGA and epilepsy or migraine. Electroencephalography abnormalities were observed in 10 (17.6%) of patients.Ĭonclusion: Our findings suggest a putative cerebrovascular background of transient global amnesia. Doppler ultrasonography of carotid arteries revealed abnormalities in 29 patients (51.8%). One patient (1,8%) suffered from migraine. In 92.9% patients chronic diseases were found, included: Hypertension (60.7%), dyslipidemia (48.2%), autoimmune thyroiditis (17.9%), and ischemic heart disease (14.3%). 35.7% patients had TGA in summer and 26.8% in winter months. The potential triggers or events before episode could be recognized in 22 patients (39.3%). Results: A total of 52 patients (92.9%) underwent their first-ever episode of TGA. Materials and Methods: A total of 56 patients (42 women and 14 men) with TGA hospitalized from 2008 to 2016 in the Department of Neurology, Wrocław Medical University. We analyzed clinical characteristics, neuroimaging, and electrophysiological findings as well as comorbidities and seasonal variation in TGA patients with regard to possible background of the syndrome. Etiology of TGA remains unclear with various hypotheses. Afterward, my son insisted that I get the cut stitched and walked me to the emergency room, where the intake doctor ruled out any medical explanation for my fall and told me to take it easy for the rest of the day.Objectives: Transient global amnesia (TGA) is a temporary short-term reversible memory loss. I had not hit my head and had no headache or bruises, but probably cut my chin on the bike basket.ĭuring the intervening minutes, although I remember none of this, I had apparently walked the bike to my house, brought in my backpack and helmet and put a package of spinach into the refrigerator. I do recall feeling great as I started a slow uphill ride on my block, something I do daily, and then remember nothing else until about 30 minutes later, when I left my house to retrieve my bicycle while holding a wet paper towel under my bleeding chin. I was not dizzy, there was no obstacle I might have hit, and I have no memory of almost falling. I now wonder if what I thought was a mild concussion was really TGA when on a beautiful September morning in 2017 I seem to have fallen off my bike for no apparent reason after swimming laps.
