When ADHD Doesn’t Quite Fit: Understanding Cognitive Disengagement Syndrome

If I’m being honest… daylight savings hit hard this year.

Not just for me, but for my clients too.

Over the past week I’ve had several clients walk into sessions looking like their brain battery was hovering around 10%. Slower thinking. More staring into space. A lot of “wait… what was I doing again?”

And honestly? Same.

But what really caught my attention was how many clients said some version of the same thing:

“I don’t know why, but I feel like I can’t keep my eyes open.”

“My brain is moving sloooooow.”

“I’m trying to focus but everything feels foggy.”

One client even paused mid-sentence and said, “Hold on… my brain just completely left the chat.”

Hearing this same pattern from several clients in the same week made me pause and wonder if something more might be going on than just daylight savings fatigue. Around the same time, a parent asked me a thoughtful question.

She said, “Do you work with kids who don’t have an ADHD diagnosis but have Cognitive Disengagement Syndrome?”

Before going any further, it’s important to say that I’m not diagnosing anyone with anything. As a coach, that’s not my role. But sometimes patterns that show up in coaching conversations can remind me of research or topics that may help families better understand what they’re seeing.

So what’s going on when a brain feels like it’s moving through molasses?

This conversation reminded me of some research I’ve been reading about a pattern called Cognitive Disengagement Syndrome, which was previously known as Sluggish Cognitive Tempo.

What is Cognitive Disengagement Syndrome?

Cognitive Disengagement Syndrome (CDS) is a pattern of attention difficulties that researchers believe may be distinct from ADHD, although the two can sometimes overlap.

For many years this pattern was referred to as Sluggish Cognitive Tempo. In 2023, researchers recommended the term Cognitive Disengagement Syndrome to better reflect the idea that the brain is disengaging from tasks or the surrounding environment.

Researchers describe CDS as including symptoms such as:

• mental fogginess

• frequent daydreaming

• slow processing speed

• low mental energy

• staring off into space

• difficulty sustaining attention

Teachers sometimes describe these individuals as:

“He’s in his own world.”

“She takes a long time to get started.”

“He just stares at the paper.”

Unlike many individuals with ADHD, these individuals are rarely disruptive.

In fact, they’re often the quiet person sitting with an assignment in front of them while everyone else seems to already be halfway finished.

Parents sometimes search things like “why does my child seem like they’re in their own world?”, and research on Cognitive Disengagement Syndrome is beginning to offer one possible explanation.

It’s a description many parents and teachers recognize immediately.

How CDS Differs from ADHD

Cognitive Disengagement Syndrome and ADHD both involve attention challenges, but the way those challenges show up can look different.

Individuals with ADHD often experience difficulty regulating attention, behavior, and activity level. This may show up as:

• difficulty sustaining attention on effortful tasks

• shifting attention quickly between things in the environment

• impulsive responses

• challenges with planning, organization, or follow-through

Individuals with Cognitive Disengagement Syndrome tend to experience challenges related more to mental engagement and alertness, such as:

• slower processing speed

• mental fogginess

• difficulty maintaining mental energy during tasks

• frequent daydreaming or mind wandering

• appearing mentally “checked out”

Many people with CDS are often described as quiet, thoughtful, or introspective, whereas ADHD can sometimes involve higher outward energy.

Neither pattern is better or worse. They simply reflect different ways attention can be regulated in the brain.

Some individuals may even show characteristics of both patterns, which can make it harder for families to fully understand what they are seeing.

And when you’re a parent trying to figure out what you’re seeing, that can feel confusing.

The Clients Who Often Remind Me of This Pattern

When I read descriptions of Cognitive Disengagement Syndrome (CDS), it reminds me of some of the thoughtful, quieter clients I work with.

They’re rarely the ones bouncing off the walls.

They’re the ones who sit quietly while everyone else seems to already know what to do.

They’re the ones who pause, think, and then answer in a way that makes you realize they were actually processing something pretty deeply.

Many of them are incredibly thoughtful, creative, and observant.

But when their brain moves at a different pace than the environment around them, it can sometimes look like disengagement or lack of effort.

And that’s usually not what’s happening at all.

In fact, many parents tell me something similar:

“My child is incredibly bright… it just sometimes takes their brain a little longer to get going.”

Why Coaching Can Be a Helpful Part of the Support System

One thing I often share with parents in these conversations is this: even though Cognitive Disengagement Syndrome isn’t the same as ADHD, many of the day-to-day challenges can look similar.

At the same time, many individuals who show CDS traits are often thoughtful, observant, and reflective thinkers. They may process information more slowly, but that slower pace can also allow for deeper thinking and creativity.

Where they often need support is with the pace and structure of everyday demands, especially in environments that move quickly.

Clients who show CDS traits may struggle with things like:

• getting started on tasks

• maintaining mental momentum

• organizing information

• sustaining attention

• feeling cognitively overwhelmed

Many of these challenges fall within the umbrella of executive functioning skills, which is where coaching can be especially helpful.

Coaching focuses on building structure around the brain. Instead of expecting someone to manage everything internally, coaching helps clients develop practical systems that support how their brain works. This might include things like:

• predictable routines

• clear starting points for tasks

• breaking larger assignments into manageable steps

• visual organization tools

• external accountability

In other words, we create scaffolding around the brain so a person doesn’t have to rely on mental energy alone.

For individuals whose attention tends to drift or disengage, that external structure can make a meaningful difference. When the environment provides the right supports, many of these individuals are able to bring their thoughtfulness, curiosity, and creativity much more fully into their work.

At the same time, coaching is often one piece of a larger support system. Depending on what a child is experiencing, families may also explore options such as educational evaluations, school accommodations, therapy, or consultation with medical professionals. Understanding how a child’s brain processes information can help families decide which combination of supports may be most helpful.

The Bigger Picture

Whether the label is ADHD, Cognitive Disengagement Syndrome, or something else entirely, the most important question isn’t the diagnosis itself.

It’s this: What helps this brain function best?

Many of the clients I work with who show these patterns are incredibly thoughtful and perceptive.

They may simply need the right supports to help their brain stay engaged and moving forward.

And with the right structure, strategies, and understanding, many of them do incredibly well.

One Final Thought

If daylight savings taught us anything this week, it’s that every brain functions differently depending on energy, sleep, and cognitive load.

Some brains bounce back quickly.

Others need more time, more structure, and more support to get moving.

And sometimes what looks like a disengaged brain is actually a thoughtful brain that simply needs the right scaffolding to stay engaged.

When we understand how a brain works, we stop asking “why aren’t they trying harder?”

And we start asking a much better question: “What support will help this brain thrive?”

And sometimes the answer isn’t pushing harder…

it’s simply building the right scaffolding for the brain that’s already there.

If your brain wandered off somewhere during this article…honestly, that would be extremely on theme.
