Is there a theoretical reason GLP-1 medications might affect focus, separate from ADHD medication?

GLP-1 receptors do exist in some brain regions beyond appetite centers, and there's ongoing broader research interest in GLP-1's potential effects on cognition and neuroprotection generally, but this isn't the same as an established, ADHD-focus-specific effect, it's a much earlier-stage and more general area of research than anything specific to attention or ADHD symptoms. Anyone noticing changes in focus while on both medications should discuss it with their provider rather than attribute it definitively to either drug without more context.
