When most people think of ADHD, they picture a hyperactive child who can’t sit still: bouncing in their chair, interrupting others, always on the move. That’s the version we hear about in school meetings and parenting blogs. But that’s just one part of the story. ADHD isn’t one-size-fits-all, and there’s a whole type that often goes unnoticed, especially in adults.
At Thrive Counseling Services, we see what happens when that quiet version of ADHD gets overlooked. It’s time to talk about it.
The Three Types of ADHD
ADHD stands for Attention-Deficit/Hyperactivity Disorder. Years ago, you might have heard the term “ADD” (without the “H”), but that label has since been folded into the broader ADHD diagnosis. The current diagnostic model identifies three main subtypes:
- Inattentive Type: Difficulty focusing, forgetfulness, easily distracted, struggles with organization.
- Hyperactive-Impulsive Type: High physical energy, impulsivity, difficulty waiting or staying seated.
- Combined Type: Symptoms of both inattention and hyperactivity/impulsivity.
The one we don’t talk about enough? Inattentive Type.
Why Inattentive ADHD Gets Missed
This quieter version of ADHD doesn’t fit the stereotype. It doesn’t always disrupt classrooms or meetings. It’s the client who zones out during conversations, loses keys constantly, or forgets what they were saying mid-sentence. They might be seen as spacey, forgetful, or even lazy, but not as someone with a diagnosable condition.
And here’s the kicker: this type often gets diagnosed much later in life — if at all. Many adults come into our offices thinking they’ve just been battling anxiety for years, when in fact, it’s unrecognized ADHD. They didn’t bounce off the walls as kids, so no one ever looked deeper.
The Overlap with Anxiety
It’s very common for inattentive ADHD to show up alongside anxiety. When your brain doesn’t slow down, it can feel like you’re always dropping the ball, missing something, or scrambling to catch up. That chronic overwhelm looks a lot like anxiety, and is often misdiagnosed as such.
At Thrive, we pay close attention to these patterns. When someone shares that they’ve been on anxiety medication but still feel like something’s off, we start asking different questions. We often refer clients for a QB test or collaborate closely with our psychiatric provider to explore a potential ADHD diagnosis. From there, we tailor support, whether that’s therapy, medication, or a combination of both.
What Inattentive ADHD Looks Like in Adults
Adults with this subtype may struggle with:
- Following through on tasks or completing projects
- Losing items like phones, keys, or paperwork
- Forgetting appointments or deadlines
- Feeling mentally “foggy” or disorganized
- Zoning out during conversations or meetings
They’re often people who’ve had to work twice as hard to stay afloat, but never realized why. Receiving a correct diagnosis feels like a puzzle piece finally fitting into place.
Treatment That Makes Sense
Inattentive ADHD is manageable. At Thrive, we integrate evidence-based therapy with optional medical management to create personalized treatment plans. Internal Family Systems (IFS) therapy helps clients better understand the parts of themselves that are trying so hard to function while feeling overwhelmed. Sometimes, medication becomes part of the plan. In many cases, it’s a game-changer.
We believe in creating a full-circle support system: one where clients don’t have to navigate their care alone.
You’re Not Broken—You’ve Just Been Missed
For many adults, finding out they have inattentive ADHD comes with a deep sense of relief. Suddenly, the pieces fit. The inner critic starts to quiet. Life begins to feel a little more manageable.
