How do specialists explain the blank stare moments in ADHD?

What people describe as zoning out or blank staring is often an attention freeze or micro shutdown. The brain becomes overloaded or disengages briefly when it cannot process incoming information fast enough. This can happen during conversations, meetings, or emotionally charged moments. It is not intentional and not the same as daydreaming. These moments are more likely under stress, fatigue, or sensory overload. The brain is essentially pausing to protect itself. Understanding this can help reduce shame and support strategies like slowing conversations or allowing brief mental resets.
