Payments from drug & device makers
What this record shows
This record is dominated by speaking fees: $184,469 of the $293,558 with a category attached, or 62.8%. 10 manufacturers reported payments, led by Biogen at 35.1% of the total. Reporting peaked in 2019 at $115,466 and has fallen 97.1% since, to $3,364 in 2025. Among neurology clinicians in IL with any reported payments, this total sits in the top 5% — high for the specialty, which is a reason to read the composition above rather than the number alone.

What the payments were tied to
Products named in the reported payments. Only payments of $100 or more are attributed here — the typical reported payment nationally is a meal worth about $16, and listing those product-by-product would be noise.
