Can Migraine Affect Your Concentration Even When the Pain Is Mild?
You’re at work. You can still function. The migraine isn’t “that bad”…
…but is your brain working at its usual level?
A new study published in BMC Neurology found that people experiencing mild to moderate migraine attacks showed reduced cognitive performance compared with people with migraine who were headache-free.
🧠 What did researchers discover?
The study included 259 people with migraine. Those experiencing a headache attack performed significantly worse on a test of attention and information-processing speed.
And here’s the interesting part:
➡️ Cognitive performance was reduced during mild as well as moderate migraine attacks.
➡️ There was no significant difference between mild and moderate attacks.
➡️ This suggests that the migraine attack itself may affect cognitive function, rather than cognitive effects simply increasing as headache pain becomes more severe.
This may help explain why someone with migraine can be physically present at work but find it harder to concentrate, process information or work as efficiently as usual—a phenomenon known as presenteeism.
Importantly, the researchers did not directly measure workplace productivity, so more research is needed to establish exactly how these cognitive changes translate into work performance.
💡 The takeaway: Migraine is not simply about the intensity of head pain. Even a relatively mild attack may have effects on how the brain functions.
