Transient global amnesia is anterograde and usually retrograde amnesia that begins suddenly and lasts up to 24 hours. It is usually a solitary event. Affected individuals lose memory function for recent events and have a decreased ability to retain new information. Transient global amnesia was defined clinically. Amnesia is only memory loss while dementia features a global loss of higher brain functions. Now on YouTube!Look for a new 5 minute video every Monday .

Transient Global Amnesia: A temporary syndrome where you experience both retrograde and anterograde amnesia. Transient global amnesia (TGA) is a neurological disorder whose key defining characteristic is a temporary but almost total disruption of short-term memory with a range of problems accessing older memories. 1-4 It has an annual incidence of 3.4 to 10.4 per 100,000 people.

Transient global amnesia (TGA) is characterized by the sudden onset of anterograde amnesia, generally lasting up to 24 hours. What is amnesia? Transient global amnesia (TGA) is generally believed to be a transient ischemic attack affecting short-term memory centers. The cumulative hazard ratio of dementia was estimated. Amnesia . A long-term follow-up study was performed on patients with transient global amnesia (TGA) in order to evaluate the prognosis, the recurrence rate and the occurrence of stroke and dementia.
