MINNEAPOLIS — Sufferers with migraine spontaneously described typical signs like ache however solely revealed cognitive signs after being requested additional questions, in keeping with a speaker on the American Headache Society 67th Annual Scientific Assembly.
Exit interviews with sufferers that yield extra complete responses might result in extra individualized therapy, Richard B. Lipton, MD, professor within the The Saul R. Korey Division of Neurology at Albert Einstein School of Medication, informed attendees.
“Folks with migraines could not absolutely report all of their signs, making it difficult to realize a full understanding of the illness and its burden,” Lipton mentioned.
Suppliers usually seize migraine symptomatology by way of spontaneous studies, he mentioned, which can result in under-reporting of signs, or by asking sufferers to finish checklists of signs, which can result in false positives.
“So, the query is, how can we as clinicians and researchers be certain that we are able to seize the complete vary of experiences and nuances in migraine symptomatology?” he mentioned.
The part 2 HOPE trial included 237 sufferers with migraine who obtained 750 mg or 100 mg of Lu AG0922, an investigational humanized monoclonal antibody that targets pituitary adenylate cyclase-activating polypeptide or PACAP to forestall migraine.
After 4 weeks of therapy and an 8-week follow-up, skilled, certified interviewers carried out exploratory exit interviews with 50 sufferers. The interviewers requested probing questions on signs that sufferers didn’t describe spontaneously.
Practically each participant spontaneously reported headache ache, Lipton mentioned. As well as, phonophobia, photophobia and nausea have been spontaneously reported at a really excessive fee.
“It’s the cardinal migraine signs which are more than likely to be spontaneously reported,” he mentioned. “However as we take a look at different signs — issue concentrating, issue remembering, adjustments in temper — these signs aren’t reported fairly often.”
Percentages of spontaneous studies vs. studies after probing included 16% vs. 70% for issue concentrating, 6% vs. 56% for issue remembering, 10% vs. 40% for issue talking or discovering phrases and 16% vs. 34% for mind fogginess.
“General, 88% of individuals in response to probing reported at the least one cognitive symptom,” Lipton mentioned. “Signs appear to cluster collectively inside people.”
Particularly, 24% of sufferers reported one cognitive symptom, 70% reported two or extra of those signs and 48% reported all 4 of those signs.
“I’d argue right here that counting on spontaneous studies could result in underreporting, for instance, with cognitive signs,” Lipton mentioned. “We establish much more symptomology by probing.”
Sufferers additionally have been requested how extreme and bothersome these signs have been on a numerical ranking scale of 0 to 10, with 0 equal to not extreme and 10 equal to very extreme.
Among the many cardinal signs, severity and bothersomeness scores included 8.9 and 9 for head ache (100%); 7.3 and 6.7 for phonophobia (94%); 7.9 and seven.4 for photophobia (90%); and 6.7 and 6.8 for nausea (88%).
Among the many cognitive signs, severity and bothersomeness scores included 6.2 and 6.1 for issue concentrating (84%); and 5.8 and 6.4 for issue remembering (60%).

Different scores included 7.3 and 6.8 for fatigue (84%); 7.3 and seven.7 for vomiting (60%); 7.3 and 6.7 for adjustments in temper/despair (58%); and 5.6 and 5.1 for feeling unusual, similar to sizzling, chilly or dizzy (56%).
“The signs that we seize by probing are literally bothersome to sufferers,” Lipton mentioned.
Moreover, 100% of sufferers mentioned that migraine impacted their day by day efficiency and way of life, together with 88% who mentioned it impacted work, 74% who mentioned it impacted their sports activities or train, and 70% who mentioned it impacted their day by day actions or routine.
Equally, 92% mentioned migraine impacts their relationships and social functioning, with affected areas together with social actions (74%), household (59%), buddies (33%) and partner or accomplice (33%).
Impacts on emotional well being, reported by 86% of sufferers, included temper adjustments (67%), anxiousness (60%), and despair (60%). Sleep disturbances, reported by 76%, included lowered high quality (66%), issue stating asleep (61%) and issue falling asleep (55%).
Lastly, 48% of sufferers reported extra impacts, together with decreased high quality of life (96%), environmental triggers (8%) and a necessity to hold their drugs with them (4%) among the many results of migraine on their lives.
“As we work towards a extra holistic patient-centered method within the evaluation of burden of migraine, the strategy of doing qualitative interviews which are embedded in a scientific trial is one thing that I feel we must always add to our strategies,” Lipton mentioned.
“What we see is, not surprisingly, with the probe, you get extra reporting, and the reporting that you just get is usually of signs that aren’t seen as cardinal migraine signs,” he continued.
Such probing reveals the complete spectrum of the impression of migraine, which might yield extra customized, focused, and complete therapy. Nevertheless, he added, additional research are wanted to show the generalizability of this method to a broader inhabitants with migraine.
“I’m curious how the outcomes would look if we did these interviews on the finish of therapy as a substitute of 8 weeks later and in addition about utilizing the embedded interview as a technique of figuring out what individuals like and what individuals don’t like in regards to the remedy they’re taking,” Lipton mentioned.
