Do I Have ADHD? Signs in Adults You Shouldn’t Ignore

If you’ve ever asked yourself, “Is this ADHD, or am I just disorganised?”, you’re not alone.

ADHD—Attention Deficit Hyperactivity Disorder—isn’t just a childhood condition. It’s estimated that over 1.5 million UK adults live with ADHD, many without a formal diagnosis. For many, the signs are subtle, masked by coping strategies or mislabelled as anxiety, depression, or burnout.

This article explores the signs of ADHD in adults, how it presents differently than in children, and how you can take the first steps toward understanding your brain better.

Why ADHD Often Goes Undiagnosed in Adults

Most adults with ADHD weren’t diagnosed as children. Why?

Because symptoms often don’t look like hyperactivity or disruption. Instead, they show up as:

• Chronic lateness

• Struggles with motivation

• Emotional overwhelm

• Burnout from constant overcompensation

Many high-functioning adults develop masking strategies—systems, lists, last-minute panic productivity—that help them survive but hide the underlying executive dysfunction.

Women and AFAB individuals, in particular, are often misdiagnosed with anxiety, depression, or BPD before ADHD is considered.

10 Common Signs of ADHD in Adults

Below are patterns frequently reported by undiagnosed adults. If several of these feel familiar, it may be worth exploring further:

1. Procrastination—Even on Important Tasks

You want to do it. You need to do it. But you can’t start.

2. Constant Forgetfulness

Keys, wallet, phone, appointments—you lose track of them all.

3. Time Blindness

You underestimate how long tasks take—or lose entire hours without noticing.

4. Emotional Reactivity

You feel easily overwhelmed, frustrated, or anxious, often without clear triggers.

5. Chronic Disorganisation

Despite best efforts, your environment feels chaotic.

6. Hyperfocus on the Wrong Things

You get lost in a task for hours—but it’s never the one you planned to do.

7. Low Frustration Tolerance

Small delays or disruptions feel emotionally explosive.

8. Trouble Finishing What You Start

Big ideas, half-started projects, and open tabs follow you everywhere.

9. Poor Sleep Regulation

Difficulty falling asleep, waking at random hours, or staying up all night hyperfocused.

10. Feeling “Different” But Can’t Explain Why

You’ve always sensed that your brain works differently—but couldn’t put it into words.

ADHD Is More Than Just “Being Distracted”

At its core, ADHD is a neurodevelopmental condition that affects the brain’s ability to manage:

• Focus and attention

• Task initiation and completion

• Emotional regulation

• Impulse control

• Working memory

There are three presentations:

• Inattentive – daydreaming, disorganisation, forgetfulness

• Hyperactive-Impulsive – restlessness, impulsivity, talking over others

• Combined – traits of both types

ADHD is listed in the DSM-5 and recognised in UK clinical guidelines (NICE). It’s not a behavioural issue—it’s neurobiological.

How to Get Assessed for ADHD (UK)

If you resonate with the above signs, there are two main pathways to diagnosis:

🔹 NHS Referral

• Speak to your GP

• Waiting times can exceed 1–3 years

• Requires completion of screening forms (e.g. ASRS, DIVA)

🔹 Private ADHD Assessment

• Faster access (often within 2–6 weeks)

• Typically includes structured clinical interview, rating scales, and full report

• May cost £500–£1,200 depending on provider

Start With a Self-Check

You don’t need to commit to an assessment today. Start small.

Final Thoughts

If you’ve made it this far, you probably don’t need more convincing that something’s not working.
But here’s the good news: there’s nothing wrong with you. Your brain is just wired differently.

Understanding ADHD is the first step toward working with your brain, not against it. Whether you choose a self-assessment, a tracker, or a professional evaluation—take the next step. Your clarity starts there.
