PsychCentral: How Does ADHD Affect Your Time Perception?
"If you live with attention deficit hyperactivity disorder (ADHD), you likely know how challenging it is to be on time. Deadlines can also plague people with ADHD. These challenges aren’t a personal failing, and they’re not solely related to inattention, a classic ADHD symptom. A symptom of ADHD called altered time perception or “time blindness” plays a large role. Folks with typical neurology often have an inner sense of how long minutes, hours, and days are, and how much they can do within each time increment. For those with ADHD, time tends to be amorphous, meaning it’s not well defined. It may feel as if time is passing you by."
