🧭 ADHD and Time Blindness: Why Time Feels “Different” for Adults With ADHD

If you live with ADHD, you’ve probably asked yourself:

• “Where did the time go?”

• “Why do I always think I have more time than I do?”

• “How can five minutes turn into 45?”

This isn’t irresponsibility — it’s time blindness, a neurological difference deeply connected to ADHD.

Research from Russell Barkley, PhD and Peg Dawson, EdD shows that ADHD affects the brain networks responsible for time perception, time estimation, and time-to-action planning.

At ADHD Philadelphia, we help adults across Pennsylvania and Delaware understand how ADHD shifts their sense of time — and how to build a better relationship with it.

🧠 Why Time Blindness Happens in ADHD

1️⃣ The Brain’s Internal Clock Runs Differently

The prefrontal cortex helps track time and maintain temporal awareness.
In ADHD, this region activates less consistently, making time feel:

• Too fast

• Too slow

• Or completely invisible

This is why adults often say:
“I didn’t realize how much time had passed.”

2️⃣ The Default Mode Network Takes Over

The DMN (daydreaming network) becomes overactive in ADHD.
Once it “steals” attention:

• Time slips by

• Tasks feel overwhelming

• Momentum disappears

This creates the famous ADHD time loop:
“I’ll start soon… wait, how is it already afternoon?”

3️⃣ Working Memory Doesn’t Hold Time Very Well

According to Barkley, working memory is like a mental whiteboard.
In ADHD, that whiteboard erases itself quickly.

So the brain loses track of:

• Deadlines

• Start times

• The order of tasks

• Whether something is urgent or not

4️⃣ Dopamine Drives “Now” vs. “Not Now” Thinking

The ADHD brain lives in two time zones:
Now and Not Now.
This leads to:

• Overestimating how long tasks will take

• Underestimating how long you’ve been scrolling

• Feeling like time is either abundant or gone instantly

Dopamine heavily influences this “temporal distortion.”

🔧 3 Tools to Improve Time Awareness

1️⃣ Use External Time Anchors

Because internal time is unreliable, external cues make a huge difference.
Use:

• Visual timers

• Alarms

• Hourly chimes

• Smart watches

• Color-coded calendars

External time = better time.

2️⃣ Break the Day Into “Time Blocks”

Research from Dawson shows that ADHD brains thrive on structure.
Try:

• Morning block

• Work block

• Recovery block

• Evening block

Time becomes easier to feel when broken into meaningful sections.

3️⃣ Use the “5-Minute Landing”

When switching tasks, give yourself 5 minutes to land.
During this time:

• Close out the previous task

• Prepare the next one

• Check the clock deliberately

This protects against time loss during transitions — a major ADHD vulnerability.

🌱 Time Blindness Is Treatable

With awareness, structure, and the right treatment, adults with ADHD can develop a healthier relationship with time — one that feels grounded, predictable, and manageable.
