Sir, We read with great interest the letter of McCorry and Crowley concerning an attack of transient global amnesia (TGA) considered secondary to herpes simplex viral encephalitis. Some features of the reported attack are unusual. The patient was a relatively young person: 39 years compared with an average age of 61 with TGA. At the beginning the patient suddenly became ‘distressed’; he realize...

We describe the case of a 79-year-old patient referred for suspected transient global amnesia, after an episode of anterograde amnesia which lasted 90 min. An EEG, performed after the episode, showed bilateral temporal electrographic seizures, orienting the diagnosis toward a transient epileptic amnesia. Transient epileptic amnesia is defined by temporal lobe epilepsy characterized by recurrent...

In this longitudinal study multichannel MEG was used to localize and to quantify focal pathological spontaneous neuromagnetic activity in six patients with transient ischemic attacks (TIA) and two patients with transient global amnesia (TGA). Slow (2-6 Hz) and beta (14-30 Hz) activity were monitored up to 10 weeks. Results were compared with normative data, and changes over time were statistica...
