No apparent increased risk of cerebrovascular events occurs in patients who have had an episode of TGA. Recent evidence suggests an association between TGA and migraine headaches as well as takotsubo cardiomyopathy. During an episode of transient global amnesia, a person is unable to create new memory, so the memory of recent events disappears. This confused state isn't caused by a more common neurological condition, such as epilepsy or stroke. Transient global amnesia (TGA) is characterised by a selective disorder of memory with a sudden onset and without any accompanying neurological deficit in. The lifetime recurrence rate is 2.9% to 23.8%. Transient global amnesia is an episode of confusion that comes on suddenly in a person who is otherwise alert. There is no established treatment for episodes. Transient global amnesia (TGA) is a temporary, anterograde amnesia with an acute onset that usually occurs in middle-aged and older individuals. TGA is self-limited and resolves within 24 hours. It often occurs in the context of physical or emotional stress. The term transient global amnesia describes what happens in an attack and was coined in the 1950s because no one could confidently explain the mechanism. The diagnosis is primarily clinical, but recent studies suggest that magnetic resonance imaging may be helpful. The main clinical feature of transient global amnesia (TGA) is an acute anterograde memory disturbance that resolves within 24 h. The pathophysiology of TGA is not well understood but may be related to impaired venous drainage of the hippocampus. A physically or psychologically stressful precipitating event, such as emotional stress, significant physical exertion, exposure to extreme temperatures, high-altitude conditions, Valsalva maneuver, acute illness, or sexual intercourse, is often the cause. Vomiting, headache, blurry vision, dizziness, and nausea may be present. Clinically, patients have time disorientation and often ask repeated questions regarding the day's events. There are no apparent long-term sequelae, and recurrence is uncommon.

1,2 As quickly as the amnesic syndrome appears, it resolves, usually within 24 hours. Without warning, the patient suddenly experiences antegrade memory loss. Most commonly seen in patients older than 50 years, TGA results from the temporary impairment of short-term memory formation. Transient global amnesia (TGA) is a dramatic event. Transient global amnesia (TGA) is a clinical syndrome characterized by anterograde amnesia, mild retrograde amnesia, and confusion up to 24 hours.
