Defensive monotropic mode describes a pattern where monotropic focus, the deep singular attention common in Autistic people, shifts from being interest-driven to functioning as an escape from overwhelm.

Dr. Neff uses this term to describe what many AuDHD people report: retreating into intense focus not for the joy of it, but to quiet the chaos of scattered thoughts, unfinished tasks, and sensory noise. For AuDHD people especially, this pattern can become a cycle. ADHD overwhelm (the “pingy” thoughts, the half-finished to-do list, the mounting emails) drives a person into the calm of deep focus. But while they are submerged, life keeps piling up. When they resurface, there is even more waiting for them, which pulls them back under.

Defensive monotropic mode can look like productivity or impressive discipline. That appearance can mask real attention dysregulation and make ADHD harder to recognize, particularly when focus lands on work that society rewards.
