Time Blindness

Time blindness is a term popularized by Dr. Russell Barkley to describe the significant difficulty people with ADHD have perceiving, estimating, and managing time accurately. It's one of the most impactful — and least understood — manifestations of the condition.

People with time blindness experience time differently: there's 'now' and 'not now' — events that haven't arrived yet feel equally distant, whether they're tomorrow or three weeks away. This produces shock when deadlines arrive ('but it felt like there was so much more time'), systematic underestimation of how long tasks will take, and difficulty planning ahead.

Time blindness also affects punctuality: the person genuinely doesn't notice they're running late, that 30 minutes have passed, or that they should have left 20 minutes ago. Others often read this as disrespect, when it's a real neurological limitation.
