Spectral asymmetries could be used in the future to recognize cases of amnesia with a high risk of epilepsy. These differences involve key areas of the memory network located in the mesial temporal lobe. We present original evidence of an increase in beta power in the affected hemisphere (AH) of TEA as compared to TGA. Significant results corresponded to the uncus and para-hippocampal gyrus, respectively Brodmann's Areas: 36, 35, 28, 34. We found a significant increase in beta band power over the affected hemisphere of TEA patients. We used an inverse problem solution to localize the source of spectral differences. EEGs were analyzed with eLORETA to evidence power spectral contrast between the two conditions. ![]() Understanding of the pathophysiological mechanisms and neuropsychological profiles of these fascinating syndromes is growing. A diagnosis of transient global amnesia (TGA) was made and she was reassured that the problem was unlikely to recur. All patients recorded EEGs after symptoms offset. An isolated and self-limiting impairment of conscious memory can occur in a variety of clinical contexts including transient global amnesia, transient epileptic amnesia, and psychogenic amnesia. 11 females/4 males) were retrospectively identified in our clinical records. 11 female/4 male 10 left and 5 right temporal epileptic focus) and 15 patients affected by TGA (65.8 7.2 y.o. Fifteen patients affected by TEA (64.2 5.2 y.o. Patients with recurrent TGA had a more frequent history of migraine than patients without recurrence (37.5 vs. It usually happens in people who are middle-aged or elderly (most commonly after the age of 60). Eight percent of patients had TGA recurrence. In this study we use power spectral analysis empowered by exact Low Resolution Brain Electromagnetic Tomography (eLORETA) to evidence the differences between TEA and TGA. Transient global amnesia (TGA) is a mysterious syndrome causing a relatively brief inability to form new memories. ![]() In a real-life scenario, differential diagnosis between these two conditions can be hard. Abstract : Transient epileptic amnesia (TEA) is a rare epileptic condition, often confused with transient global amnesia (TGA).
