Time blindness is one of the most frustrating and misunderstood symptoms of ADHD. It can lead to chronic lateness, missed deadlines, and difficulty sticking to routines, all of which can severely affect everyday life.

However, it is not your fault–and there are ways to overcome these challenges. Learning about time blindness and ADHD can help people with the disorder understand why it happens. Informing yourself on the condition is a great first step toward managing the symptoms. Keep reading to learn more!

Key Points:

  • ADHD time blindness is due to differences in the brain. It is not the result of carelessness, laziness, or not trying hard enough.
  • Time blindness can affect all areas of a person’s life. We provide examples of what it can look like to help you recognize these patterns in your own life.
  • There are effective strategies to help manage ADHD time blindness, which you can implement on your own or with the help of a mental health professional.

What is Time Blindness?

“Time blindness” refers to difficulty perceiving and managing time. People with ADHD often have trouble estimating how long a task will take or keeping track of time during an activity. Both of these are examples of time blindness.

It’s important to note that ADHD time blindness is not a personality trait or moral failing. It’s not purposeful, and it’s not about a lack of care or not trying hard enough. Time blindness is a very real ADHD symptom, for many people with the disorder, time blindness is a focal symptom.[1]

Why ADHD Causes Time Blindness

Time blindness in ADHD is attributed to differences in the brain:

  • Prefrontal Cortex: The prefrontal cortex affects organizing, planning, focus, and time management (including time perception and time estimation). With ADHD, the prefrontal cortex can show reduced activity, is often smaller, and may develop more slowly. This can lead to poor executive function.
  • Dopamine: Dopamine is a neurotransmitter. It helps regulate the brain’s sense of time and links perception with reward.[2] So, for people with ADHD, fun or rewarding tasks might seem to fly by, whereas uninteresting tasks seem to drag on.
  • Cerebellum: The cerebellum acts as an internal clock, affecting the timing of actions and perception of the timing of stimuli.[3] Research repeatedly shows differences in cerebellar volume and function in people with ADHD.
  • Hyperfocus: People with ADHD can hyperfocus on certain tasks that they really enjoy. They can zone in so much that they lose their sense of time while partaking in that task.

Time blindness can be hard for other people to understand, specifically if they aren’t familiar with ADHD. It can affect virtually every area of your life.

How Time Blindness Affects Daily Life

Some examples of how and where this might show up for you include:

  • Interpersonal Relationships: People in your life may not see you as reliable due to challenges like frequently being late, which can strain romantic relationships, friendships, and family life.
  • Work: You might miss meetings or deadlines, show up late, or overcommit (take on too many projects at once) because tasks seem like they’ll take less time than they actually do.
  • School: For children with ADHD and college students, time blindness can lead to tardiness, failing to turn assignments in on time (or at all), and procrastination.
  • Self-care: An example of how this can impact self-care is not getting enough sleep because you didn’t go to bed early enough, or missing meals because you got fixated and forgot.

Many people with ADHD, especially if it goes undiagnosed and untreated, feel a great deal of shame due to time blindness. The constant stress caused by time blindness can severely impact your self-esteem and overall mental health.

This is why properly identifying ADHD time blindness is important! Acknowledging time blindness is a symptom of your ADHD allows you to stop blaming yourself, replacing the stress and frustration with understanding and compassion. Then, you can effectively start finding the right skills or tools that work for your brain.

Examples of Time Blindness in ADHD

It can be challenging to identify time blindness if you don’t know what it looks like. So, what are some examples? People with ADHD time blindness might:

  • Get “stuck” or fixated on an activity: For example, playing a video game for hours when you only intended to for 30 minutes, not realizing how much time has passed. Hours feel like minutes! This deep absorption in an activity is nicknamed “hyperfocus.” This tends to happen with tasks someone really enjoys.
  • Feel like tasks are taking longer than they are: Opposite to hyperfocus, ADHD time blindness can make it seem like boring or monotonous activities are never-ending. Waiting in line or completing repetitive tasks might make you feel like hours have passed by, but really, you’ve only been there for a few minutes.
  • Underestimate how long a task will take: For example, thinking that you have enough time to go to the store before a dentist appointment, only to be late for the appointment because the store took longer than you realized.
  • Struggle with transitions: Time blindness can make it difficult to transition from one task to another. This can be connected to hyperfocus.
  • Put tasks off: Similar to how one might underestimate how long something will take, you might put off tasks because you overestimate the time or effort they require, leading you to feel overwhelmed and avoid the task.

Though it’s not limited to ADHD, some experience what’s called “waiting mode.” Waiting mode is when you feel frozen in anticipation, unable to act or complete other tasks right now, because you know something’s happening later. With ADHD, waiting mode usually occurs because you fear losing track of time. To compensate for time blindness, you fixate on the event.

Time Blindness in Adults vs Children

Time blindness affects both children and adults with ADHD. However, the consequences and what it looks like can vary based on age.

In children and teens with ADHD, time blindness might entail…

  • Missing curfews.
  • Getting bored or impatient easily.
  • Not completing homework, tests, or school assignments due to losing track of time.
  • Not getting ready on time because they think they have more time than they do, even if they are reminded or told to get ready.
  • Constant “When?” questions (e.g., “When can we go to the park?” “Can we leave now?”)
  • Getting stuck or fixated on rewarding activities, like watching a video or TV show. They might say “five more minutes” without looking up, and when five minutes pass, it could still be tough to get them to break focus.

Adults with ADHD can share similar struggles. But, in adulthood, the stakes can be higher. It might be challenging to get a child with ADHD who is fixated on something to shift gears. However, an adult is usually there to help. Once you grow up, no one’s there to redirect you or remind you that it’s time for lunch.

An adult affected by ADHD time blindness might manifest in ways such as:

  • Difficulty with scheduling. You might double-book or plan too much for one day without realizing it. Some adults with ADHD–especially those with co-occurring anxiety–might feel overwhelmed by the thought of scheduling activities, which could lead them to avoid things like making a doctor's appointment.
  • Thinking you have time to complete multiple tasks when you don’t. You might think you can shower, get dressed, make dinner, eat, and clean up in 30 minutes, when really, finishing all of these things will take much longer.
  • Being late to work or social events, even if you are excited and try very hard to be on time. This is an example of what can happen when you feel like you have more time than you do!
  • Financial difficulties due to poor financial planning or trouble remembering to pay bills.

At any age, learning how to manage time blindness in ADHD can unload a great deal of stress and strain on daily life. The sooner you’re aware of the signs, the better; it means that you can begin to find strategies that work for you. It’s also never too late!

Strategies to Manage ADHD Time Blindness

Widely, experts now agree that ADHD treatment should focus more on time perception.[4] Managing ADHD and time blindness usually requires a multifaceted approach (e.g., combining helpful strategies, like those listed below, with medication and therapy).

  • Log Time Spent on Activities: To help yourself more accurately predict how long tasks take, start logging how long daily life activities take. Keep a written record for a while until you have a reliable timeframe.
  • Add an Extra Half Hour: To prevent lateness, give yourself extra time. For example, if you expect that an activity will take one hour, set aside an hour and a half to do it.
  • Set Consistent Routines: When it comes to things you do regularly–like getting ready for work–sticking to consistent routines can help you manage time.
  • Timers, Calendars, and Alarms: External tools, like timers, calendars, and alarms, are helpful for many people with ADHD. The same is true for lists and apps; everyone’s different, so don’t give up if one tool you try doesn’t work. There are even time-tracking apps you can download made to help people with ADHD manage time blindness.
  • Pause Before Saying Yes: If you know you tend to overbook, double-book, or take on too much, practice saying “I’d love to–let me check my schedule to make sure I can!” before saying yes.

Most importantly, use self-compassion. It takes trial and error to learn how to better manage time blindness, and the process might not be linear. ADHD specialists, like the therapists and psychiatrists at Clarity Clinic, can provide guidance and help you celebrate your successes along the way.

When Time Blindness Signals ADHD

ADHD isn’t the only possible cause of time blindness. So, how do you know when time blindness signals ADHD? You may want to pursue an ADHD evaluation if you experience “red flags” for ADHD time blindness, such as:

  • Poor time estimation (e.g., underestimating how much time a task will take or how much time has passed).
  • Problems with working memory (difficulty holding time-related information in the mind).
  • Difficulty transitioning from one task to another.
  • Trouble planning ahead.

The biggest indicator? If time blindness isn’t the only ADHD symptom you are experiencing, getting a professional's opinion is worth it. A diagnostic evaluation can give you a definitive answer as to whether you have ADHD and direct you toward the next steps.
