## What The Sources Report

- Connections between the gut and brain have been found crucial to maintaining
homeostasis by regulating both the central nervous system and the enteric nervous
system. [Grodzka Olga (2025); evidence level 1]
- In addition to its high prevalence and disability burden, migraine is associated with substantial socioeconomic costs, with estimated direct and indirect expenditures of approximately USD 36 billion annually in the United States. [Koz&#225;k M&#225;rk (2026); evidence level 3]
- Clinically, migraine is characterized by recurrent attacks of moderate-to-severe headache lasting 4-72 h, typically unilateral and pulsating, aggravated by routine physical activity, and frequently accompanied by photophobia and phonophobia; in a substantial subset of patients, attacks are associated with reversible focal neurological symptoms called aura. [Koz&#225;k M&#225;rk (2026); evidence level 3]

## How To Read This Evidence

Evidence level 1 generally reflects systematic reviews or meta-analyses. Level 2 includes randomized trials, guidelines, or public-health guidance. Level 3 usually reflects observational or narrative-review evidence. Level 4 is weaker or early-stage evidence. The level is a sorting aid, not a final quality grade.

## Practical Interpretation

There is at least one systematic-review style source in the current set, so it deserves more weight than single-study evidence. For probiotics migraine meta-analysis, the next editorial step is to add more targeted sources and separate strong findings from early or indirect evidence.

## Limits Of This First Pass

This is a small-batch MVP article. It uses the first ingested sources for this topic and should be expanded with more targeted searches, license review, and human editorial checks before being treated as a definitive review.
