The rate of recurrence is between 6% and 10% per years. It usually affects patients between the ages of 50 and 70 years, at an average age of 61 years occurrence in patients younger than 40 years of age is rare. Transient global amnesia (TGA) is a clinical syndrome characterized by anterograde amnesia, mild retrograde amnesia, and confusion up to 24 hours. What causes transient global amnesia is not known, but a similar, temporary loss of memory can result from drinking too much alcohol or taking certain drugs. Transient global amnesia (TGA) is a sudden, temporary interruption of short-term memory. TGA has an incidence of 3-8 per 100 000 people per year. Transient global amnesia is a sudden, temporary loss of memory for events during, after, and sometimes before the event that caused the amnesia. Transient global amnesia (TGA) is a neurological disorder whose key defining characteristic is a temporary but almost total disruption of short-term memory. The ability to store new memories gradually recovers and subjects return to normal conditions except for a substantial amnestic gap for the duration of the attack. Focal neurological symptoms and epileptic features are absent and general conditions appear intact. During the attack patients remain conscious and communicative and personal identity is preserved. What causes TGA For years this question has been debated. There are no apparent long-term sequelae, and recurrence is uncommon. Transient global amnesia (TGA) is a clinical syndrome characterized by anterograde amnesia, mild retrograde amnesia, and confusion up to 24 hours. 1,2 As quickly as the amnesic syndrome appears, it resolves, usually within 24 hours. Without warning, the patient suddenly experiences antegrade memory loss. It is associated with retrograde amnesia and repetitive questioning. Transient global amnesia (TGA) is a dramatic event.
