![]() ![]() There is conflicting evidence as to whether an episode of TGA predisposes to future seizures or dementia. 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. It’s as if the brain is on overload and takes a break to. The lifetime recurrence rate is 2.9% to 23.8%. A diagnosis of exclusion: transient global amnesia, often called TGA.It is a temporary lapse in memory that can never be retrieved. During an episode of transient global amnesia, your brain refuses to make new memories so recall of recent actions and events simply vanishes. Finally, transient Global Amnesia can be iatrogenic, that is to say, linked to the intake of certain substances such as alcohol. Transient global amnesia is a sudden, temporary episode of memory loss that can’t be attributed to a more common neurological condition, such as epilepsy or stroke. There is no established treatment for episodes. This sudden loss of memory mainly affects people between the ages of 50 and 70 and can occur after. 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. 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. 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. Transient global amnesia is a sudden, temporary loss of memory for events during, after, and sometimes before the event that caused the amnesia. 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. 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 clinical syndrome characterized by anterograde amnesia, mild retrograde amnesia, and confusion up to 24 hours. ![]()
