Cognitive dysfunction during mild to moderate migraine attacks: potential implications for presenteeism.
Article in BMC neurology, 2026. 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
backgroundMigraine-related presenteeism is a global concern, arising when individuals attend work during a headache attack, resulting in reduced performance. To clarify this issue, we investigated the effect of the presence and severity of headache attacks on cognitive function in patients with migraine.
methodsWe conducted a retrospective analysis of prospectively collected cohort data from April to December 2019, enrolling participants aged 18–80 years who met the ICHD-3 criteria for migraine. Participants were categorized into four groups based on headache (HA) intensity at the time of their clinic visit: no HA, mild, moderate, or severe. Cognitive function was assessed using the Digit Cancellation Test (D-CAT) and the Trail Making Test (TMT). Patients with severe HAs were excluded, as pain relief treatment was prioritized. Statistical comparisons were conducted across the remaining groups.
resultsA total of 259 patients were analyzed, including 125 without HAs (HA (−)) and 134 with HAs (HA (+)), of whom 79 were mild and 55 were moderate. The HA (+) group showed significantly lower D-CAT scores compared with the HA (−) group (p < 0.05), while TMT scores did not differ significantly between the two groups. Within the HA (+) group, no significant differences in D-CAT or TMT scores were observed between patients with mild and moderate HAs. Similarly, cognitive scores did not differ between migraine patients with and without aura.
conclusionMigraine patients experiencing a headache attack had reduced cognitive function compared with HA-free migraine patients, and this dysfunction was independent of HA severity. These findings suggest that the presence of a headache attack itself – regardless of its severity – may impair cognitive function and have potential implications for work efficiency and presenteeism.
