The Overlap of Migraine and Transient Global Amnesia: A Case Report and Literature Review on the Concept of "Migramnesia".
Article in Case reports in neurology. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction: The pathophysiological relationship between migraine and transient global amnesia (TGA) remains unclear. We present a case of TGA occurring temporally with a migraine attack and review the existing literature on this potential association, sometimes termed "migramnesia." Case Presentation: A 58-year-old man with a history of episodic migraine with aura experienced a severe typical migraine headache. Approximately 3 h after onset, he awoke with profound anterograde and retrograde amnesia lasting 3 h, meeting clinical criteria for TGA. He had no recollection of the amnestic episode or the preceding headache. Brain MRI was unremarkable. Conclusion: This case adds to the limited number of reports describing a temporal link between migraine and TGA events. A review of the literature reveals conflicting evidence regarding migraine as a risk factor for TGA recurrence. While our case and some studies suggest a plausible association, the evidence is inconsistent. This case highlights the need for further research, including rigorous prospective studies and analyses of potential migraine-related subgroups within TGA populations, to clarify any underlying pathophysiological connections.
