I have said, often, repeatedly, that I can’t think through a migraine. One assumes it is the pain level. Or is it the migraine itself?
Well, guess what they did a study on that. How thinking is impacted by a migraine. And we are right… we are dumified by a migraine. Or to put it better there is cognitive dysfunction with migraines, that is not permanent but certainly feels that way when migraines are way more frequent than not.
The study was on migraine without aura. I would assume it is the same with aura, if not worse given aura symptoms.
Thirty-nine patients with episodic migraine (37 females, average 38 years old) were included and 24 completed the study. Participants performed worse during the attack in the majority of cognitive tests, compared to the headache-free status, and significantly so in word reading speed (p = 0.013), verbal learning (p = 0.01), short-term verbal recall with (p = 0.01) and without (p = 0.013) semantic cueing and delayed recall with (p = 0.003) and without (p = 0.05) semantic cues. Differences found were unrelated to age, gender, literacy, condition order, interval between evaluations, anxiety, pain intensity or duration of the attack. PubMed Cephalalgia.
In the end they conclude “Cognitive performance decreases during migraine attacks, especially in reading and processing speed, verbal memory and learning, supporting patients’ subjective complaints. These findings suggest the existence of a reversible brain dysfunction during attacks of migraine without aura, which can relate specifically to migraine or be a consequence of acute pain processing by the brain.”
So either due to the migraine or the pain. Either way, that is a lot of dysfunction. For example, the one damn thing fibrofog doesn’t touch? Processing speed. And migraines do. That is impressive in a bad way. What is processing speed? “Processing Speed is one of the measures of cognitive efficiency or cognitive proficiency. It involves the ability to automatically and fluently perform relatively easy or over-learned cognitive tasks, especially when high mental efficiency is required. That is, for simple tasks requiring attention and focused concentration. It relates to the ability to process information automatically and therefore speedily, without intentional thinking through.” ETFO Like reading comprehension and doing simple math. Ever have a problem doing simple math in your head with a migraine? Processing speed issues. Ever read a sentence and not comprehend it? Or delayed comprehension? Processing speed. Fail to recognize an object? Or delayed comprehension? Processing speed. Copy words and sentences incorrectly? Processing speed. Taking a longer time to respond to a question or respond to written instructions. All processing speed. That system getting glitchy can slow a person right down. I call it having to be really methodical in my steps. Makes my brain feel slower than molasses. Pudding brain, I call it. It can affect how we comprehend in conversations to how overwhelmed we become in by too much information at once. I know with a migraine thinking has to be very This Step and then This Step. So this study is intriguing because it shows the limitations we have cognitively with a migraine. And the frustrations that come with that.
Makes me think it is more than pain when they say it affects processing speed. But that is because I have read the research on FM where pretty much everything from short-term, long-term and working memory is affected by pain, except processing speed.
