The cause of TGA is however still unknown. TGA is thought to result from a temporary hippocampal dysfunction supported by the clinical presentation and MRI findings. Our findings regarding age, sex distribution and precipitating events were in accordance with other studies. MRI showed restricted diffusion in the hippocampal area in 10.3% of cases.ĭISCUSSION: TGA is not a rare but a benign syndrome. In 96% of patients a computerized tomography was performed (no sign of acute changes were found), and magnetic resonance imaging (MRI) in 36.2% of cases. Possible precipitating events were found in 53.7% of cases, with physical activity being the most common one (24.4%), followed by sudden temperature change and emotional stress. The sex distribution was equal (49.9% female). 6) mild memory disturbance due to known physiological condition (F06. The mean age was 64.1, with 50% of subjects between 58-70 years old. Amnesia Amnestic disorder Memory loss Post-traumatic amnesia Posttraumatic amnesia amnestic disorder due to known physiologic condition (F04) amnestic syndrome due to psychoactive substance use (F10-F19 with 5th character. RESULTS: Overall, 348 attacks of TGA were identified with a mean frequency of 29 attacks/year, where 9.9% had an earlier history of TGA. Statistical processing was performed with Excel and Rstudio. Medical records were reviewed, and information about year and age at diagnosis, sex, symptoms, precipitating events, imaging results and risk factors were collected. METHODS: We retrospectively analysed the medical history of patients with a diagnosis of TGA (ICD-10 G45.4) at the University Hospital in Iceland in 2010-2021. The aim of this study was to study TGA in the greater Reykjavik-area. Transient total amnesia (TGA) is a neurological disorder characterized by a temporary but near-total destruction of short-term memory, with various problems. TGA appears without other focal neurological symptoms.
