Transient Global Amnesia
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. During an episode of transient global amnesia, your recall of recent events simply vanishes, so you can’t remember where you are or how you got there.

- Clinical manifestation and imaging characteristics of transient global amnesia: patent foramen ovale as an underlying factorby Sang-Mi Noh on October 14, 2021
Transient global amnesia is not rare, but its etiology remains unknown. Cerebral ischemia is a suspected cause because high signal intensity is observed on diffusion-weighted brain magnetic resonance imaging; however, previous studies have not established it as a cause. Of the 128 patients (114 females) enrolled in this study, 82 (64.6%) experienced extreme stress before transient global amnesia. The number of female patients with patent foramen ovale was more than that of males. The patent...
- Acute coronary syndrome and transient global amnesia with sumatriptanby Edward Lee on October 9, 2021
Triptans are potent serotoninergic vasoconstrictors. They are generally avoided in elderly patients age greater than 65 or in patients with a history of CAD. Although there are reported cases of Acute Coronary Syndrome (ACS) or Transient Global Amnesia (TGA) in patients after ingesting therapeutic doses of triptan or dihydroergotamine, this is the first case report, up to our knowledge, of a patient, who had no previous cardiac history, that was diagnosed with both ACS and TGA. A 59-year-old...
- Non-pharmacological intervention in post-traumatic amnesia, a systematic reviewby E Vilageliu-Jordà on September 27, 2021
CONCLUSIONS: According to the results obtained, there is evidence that non-pharmacological interventions have positive effects on reducing the cognitive-behavioural signs and symptoms associated with post-traumatic amnesia.
- Sensitivity of diffusion-weighted magnetic resonance imaging in transient global amnesia as a function of time from symptom onsetby Matthew L Wong on September 13, 2021
CONCLUSION: DW-MRI lesions are uncommon in patients with TGA early after symptom onset, but the sensitivity (i.e., positivity rate) of DW-MRI increases with time. Despite the limited quality of existing evidence, obtaining an early DW-MRI in patients with clinical diagnosis of TGA in the acute setting is likely a low-yield test.
