I do not routinely recommend imaging or EEG for clinically straight-forward patients with Transient Global Amnesia (TGA), although I suspect I am in the minority. When the diagnosis is in question, or when the symptoms have not resolved, then yes, I would do additional workup, including MRI and EEG....

MRI/MRA with stroke protocol (DWI, ADC) makes sense, even though it is unlikely to be positive. Better safe than sorry!

For straightforward TGA (without atypical features), I do not like routine imaging or an EEG, because it often does not change management. Having said that, >50% of my stroke attendings (n=10) will recommend ordering a fast protocol MRI (which includes DWI and FLAIR) routinely no matter the clini...

TGA is analogous to TIA. I would work up the patient as TIA and follow TIA protocols at your local institute.

As I answered before, other neurologic diseases could present as TGA. Since MRI is now easier to get but still clinically expensive, at least I will do one without contrast. That will depend also upon my level of suspicion.

I am no stroke neurologist, but in my experience in the era of more rapidly available CTH/CTA (+/-CTP), I have skipped MRI especially in the ER presentation. This is for the straightforward TGA case, often a good majority of them are improving already by the time they present. Having a negative CTA ...

I’ve been keeping track, since my residency in 2012, of patients who had a lapse of time and or lapse of memory. The symptoms, in general, were consistent with TGA, typical or atypical, and at baseline when I saw them, 32 patients in total: All had MRI b and EEG; 11 had embolic cortical MC...

Like Dr. @Cara Harth, I do not recommend neuroimaging or EEG for straightforward classic cases of TGA meeting previously reported diagnostic criteria.
