There is conflicting evidence as to whether an episode of TGA predisposes to future seizures or dementia. This includes the inability to form new memories and recall events that happened after the amnesia occurred. No apparent increased risk of cerebrovascular events occurs in patients who have had an episode of TGA. Transient global amnesia is defined as a sudden but temporary loss of memory. Recent evidence suggests an association between TGA and migraine headaches as well as takotsubo cardiomyopathy. The lifetime recurrence rate is 2.9% to 23.8%. There is no established treatment for episodes. TGA is self-limited and resolves within 24 hours. The diagnosis is primarily clinical, but recent studies suggest that magnetic resonance imaging may be helpful. 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. Tips to help enhance memory and get support can help people with amnesia and their families cope. There's no specific treatment for amnesia, but treatment can be directed at the underlying cause. Vomiting, headache, blurry vision, dizziness, and nausea may be present. Unlike a temporary episode of memory loss, called transient global amnesia, amnesia can be permanent. Clinically, patients have time disorientation and often ask repeated questions regarding the day's events. These episodes come on suddenly and typically last for a few hours before resolving on their own. Most commonly seen in patients older than 50 years, TGA results from the temporary impairment of short-term memory formation. Transient global amnesia is a temporary loss of some memory.

Transient global amnesia (TGA) is a clinical syndrome characterized by anterograde amnesia, mild retrograde amnesia, and confusion up to 24 hours. Post-traumatic amnesia (PTA) is the time after a period of unconsciousness when the injured person is conscious and awake, but is behaving or talking in a.
