“…Indeed, many patients with TGA fall out of this categorization and are described as single reports in the current literature. The patients with TGA but with structural brain lesions, such as cerebral ischaemia, meningioma, EEG recording abnormalities, viral encephalitis or drug intoxication, have been sometimes described as isolated cases, but their role in the overall spectrum of TGA has never been considered [21][22][23][24][25][26][27][31][32][33][34][35][36][37][38][39]. This is probably because most works that focused on the aetiology of TGA excluded patients with brain structural lesions considering them as confounders in an aetiological study.…”

“…Other case reports support an arterial insufficiency etiology, describing TGA symptomatology secondary to vascular disease processes. 76 – 80 Intriguingly, aortic dissection, a potentially critical break in the lining of the main arterial outflow from the heart classically associated with severe chest pain and frequently a devastating diagnosis, has been reported to present with TGA-like symptoms in nine cases, five of whom were without chest pain, 78 although the latter could be attributed to the patients’ altered mental status. Regardless, recognition of painless aortic dissection in the differential of TGA is imperative.…”

Transient global amnesia (TGA) is a clinical syndrome characterized by the sudden onset of an extraordinarily large reduction of anterograde and a somewhat milder reduction of retrograde episodic long-term memory. Additionally, executive functions are described as diminished. Although it is suggested that various factors, such as migraine, focal ischemia, venous flow abnormalities, and epileptic phenomena, are involved in the pathophysiology and differential diagnosis of TGA, the factors triggering the emergence of these lesions are still elusive. Recent data suggest that the vulnerability of CA1 neurons to metabolic stress plays a pivotal part in the pathophysiological cascade, leading to an impairment of hippocampal function during TGA. In this review, we discuss clinical aspects, new imaging findings, and recent clinical–epidemiological data with regard to the phenotype, functional anatomy, and putative cellular mechanisms of TGA.

“…Furthermore, posterior circulation angiography is associated with TGA more often than anterior circulation angiography, suggesting that disturbance or injury to the posterior circulation supplying the hippocampus contributes to TGA. Cerebral angiography-related microembolism, vasospasm, hypoperfusion, and contrast dye neurotoxicity have also been suggested as mechanisms underlying the development of TGA [7]. Acute pain due to arterial puncture or anxiety related to the procedure may involve the Valsalva-associated activities or stress responses leading to increased cortisol levels.…”

“…Therefore, they may act as predisposing conditions for TGA. In particular, we previously reported a case of cerebral angiography and stenting-related TGA [7] and additionally experienced 2 cases of gastroscopy-related TGA. In the present study, we performed an extensive literature search using PubMed to find reports of medical procedurerelated TGA.…”

Background: Transient global amnesia (TGA) is an interesting clinical syndrome characterized by sudden memory loss for recent events and an inability to retain new memories usually lasting several hours and recovering spontaneously. We conducted a literature search of medical procedure-related TGA and its predisposing conditions. Methods: We performed PubMed searches using the keyword “transient global amnesia” combined with “procedure,” “test,” “therapy,” or various other individual medical procedures. In addition, we described 2 cases of gastroscopy-related TGA. Results: Eighty-nine patients with medical procedure-related TGA in 49 articles were summarized. The most common procedure was cerebral angiography (n = 45), followed by coronary angiography (n = 10) and general anesthesia (n = 9). After categorization, neurological procedures were most common (n = 46, 51.7%), followed by cardiac (n = 17, 19.1%), anesthetic (n = 11, 12.4%), gastrointestinal (n = 4, 4.5%), and pulmonary (n = 2, 2.2%) procedures. Conclusions: Diverse cases of medical procedure-related TGA have been reported in the literature. Valsalva-associated activities, emotional stress with anxiety, and acute pain were predisposing conditions. An understanding of medical procedure-related TGA may be important for clinicians who perform such medical procedures.
