# AI analysis of 43,000 health records reveals migraine's systemic signature and four subgroups

NTNU AI study of 43,000 health records finds migraine leaves bodywide traces and has four subgroups.

Researchers at NTNU developed an AI model that used 60 non-headache variables such as age, sex, constipation, medication use, and back pain, and the model distinguished people with migraine from those without headaches. [^1]

The NTNU researchers' AI analysis identified four distinct subgroups of migraine: an all-male group, a group with prominent neck pain, a group with musculoskeletal pain, anxiety, and depression, and a group with classic migraine including aura. [^2]

Anker Stubberud said the AI model's ability to identify migraine without headache data suggests the condition leaves biological traces that extend far beyond the attacks. [^3]

Anker Stubberud, a physician and headache researcher at NTNU, said there are no blood tests or biological tests for migraine and that AI could help make correct diagnoses. [^4]

Humans developed writing approximately 5,500 years ago, a skill that was key to the development of civilization and allowed us to record our history. [^5]

The study noted that the presence of oscillations in theta and alpha bands increases, which is linked to working memory, sustained attention, and the acquisition of new learning. [^6]
