Understanding ADHD in Teens: what’s really going on
A teenager with ADHD can be completely absorbed in something one minute, unable to start something else the next, overwhelmed by what seems like a small request, or suddenly unable to cope with something they managed perfectly well last week. For parents, that inconsistency can be one of the hardest things to understand.
In our latest live session, Nurse and ADHD and Executive Function Coach Liz Ambler helped us look beneath some of the behaviours we see and understand a little more about what might actually be going on.
We’ve talked about ADHD several times over the past year, so rather than covering all the same ground again, here are some reminders, alongside some of the new ideas Liz shared tonight.
First, Remember What's Underneath the Behaviour
ADHD affects executive functioning, the skills we use to start tasks, organise ourselves, manage time, regulate emotions, remember information and move from one thing to another. So when a teenager procrastinates, forgets, becomes frustrated, avoids something or simply appears unable to get going, a useful question remains:
“What’s getting in the way?” rather than “Why won’t they just do it?”
And as we heard again tonight, ADHD and ordinary teenage development can be difficult to separate. Hormones, tiredness, school, friendships and the increasing demands of adolescence can all add to what is already going on.
Overwhelm, Shutdown, Meltdown or Burnout?
One of Liz’s really useful distinctions was that these are not all the same thing, and understanding what is happening can help us respond differently.
Overwhelm happens when the nervous system is taking in more than it can process. That might be noise, people, emotions or simply too many decisions. Reduce the input, reduce the choices and allow some processing time. Recognising overwhelm, shutdown…
Shutdown is the nervous system saying “no more”. Your teenager might become very quiet, still, glazed or find it difficult to speak. This is a time for space, silence and fewer demands, rather than lots of questions about what is wrong. Recognising overwhelm, shutdown…
Meltdown or emotional dysregulation is when everything has reached capacity and spills over. It might look like crying, shouting or lashing out. Liz stressed that this isn't simply a tantrum. Keep communication minimal, concentrate on safety and help them regulate rather than trying to reason with them. Recognising overwhelm, shutdown…
Burnout builds over a much longer period, often following repeated overwhelm or prolonged masking. A teenager may seem to be running on empty, lose some of their usual ability to function and become more sensitive to things around them. Rest, reduced demands and time become particularly important. Recognising overwhelm, shutdown…
Sometimes Helping Can Become Another Demand
This was such a simple point from Liz. When your teenager is already overwhelmed, even a caring “What's wrong?”, “What can I do?” or “How can I help?” can become one more thing their brain has to process. Sometimes the best response is simply to be there and be quiet.
Then, when everyone is calm, ask what would actually help next time. Do they want you nearby? Do they want space? Is touch helpful or not? Agreeing this beforehand gives you both something to work from when thinking clearly is much harder. Pasted text
Validate, Acknowledge, Normalise
Liz gave us a useful little tool: VAN.
Validate: “I can see that made you really angry.”
Acknowledge: “You must have felt really left out.”
Normalise: “I'd probably feel like that too.”
You aren't necessarily agreeing with everything that happened. You're recognising the feeling without judgement. Liz also made the important point that some teenagers will find even this annoying in the moment, so, as ever, know your teenager. Pasted text
Praise Doesn't Always Feel Like Praise
We often talk about building the self-esteem of teenagers with ADHD, but Liz added an interesting twist: not everybody likes being praised. Some teenagers feel uncomfortable being singled out. Instead of “You did that brilliantly”, try focusing on what happened:
“That went really well, didn't it?”
Then perhaps ask what they think helped. It shifts the attention away from them personally and helps them begin to recognise for themselves what worked. Don't let praise wipe out the difficulty. “I know that was really hard for you, and look what you managed” acknowledges both.
It Isn't Always a Motivation Problem
This was one of the most useful parts of tonight. A teenager can desperately want to do something and still be unable to start. They can even struggle to move from one activity they enjoy to another activity they enjoy. Liz explained that what looks like poor motivation can actually be difficulty with task initiation and transitions.
Moving from one thing to another isn't necessarily one simple step. They have to stop what they're doing, mentally let go of it, work out what's next, make the transition and then get started. That's a lot of executive functioning.
When “Just Do It” Really Isn't That Simple
Liz described three forms of ADHD paralysis:
Task paralysis: knowing what you want or need to do but being unable to start
Mental paralysis: having so much going on that your brain becomes overwhelmed and freezes
Choice paralysis: having so many options that your brain effectively times out. ADHD paralysis v2 Sept 2026
So when we're thinking “Just get started!”, they may be thinking exactly the same thing themselves.
Some of Liz's suggestions were reassuringly simple:
Try it for just five minutes
Break something into manageable chunks
Use a timer
Try a body double, simply having somebody else nearby while they get started
Put some music on
Change the environment
Get up and move
Tick things off as they're completed
Use small rewards, including simply recognising the satisfaction of having done it. ADHD paralysis v2 Sept 2026
And if you've agreed they only need to do something for half an hour, resist “You've done so well, why don't you carry on?” Keeping your word helps preserve trust.
Build a Toolkit, Not One Perfect Strategy
Something works brilliantly for two weeks and then suddenly doesn't. That doesn't mean it has failed forever.
Liz suggested thinking of strategies as a toolkit. If the timer isn't working today, put it back in the box and try movement, music, body doubling or something else. It may work again another time.
That takes some pressure off parents too. You don't have to discover the magic strategy that fixes everything.
Try a Building Block Audit
This was probably our favourite takeaway from tonight. Liz talked about the foundations that support executive functioning and general wellbeing:
Fun. Joy. Calm. Sleep. Food. Safety. Exercise. Connection.
Her suggestion was to turn these into a simple Building Block Audit. Then, sit down together and score each one from 1 to 5.
Which blocks feel strong at the moment?
Which feel a little “squashy”?
Where is the foundation wobbling?
Then think about what could help strengthen a weaker block.
If connection is low, perhaps they haven't seen friends outside school recently. If fun is missing, what do they actually enjoy? If exercise is low, don't impose the activity you think they should do; find something that works for them.
You could even create a little menu of things that help for the times when one of those blocks starts dipping.
Importantly, Liz suggested doing this as a family, not turning it into another exercise aimed solely at the teenager with ADHD. Pasted text
Notice, Name, Nurture
The Building Block Audit also helps teenagers begin to notice their own patterns. Perhaps they're more irritable when they haven't eaten properly. Maybe they're grinding their teeth when stressed. Perhaps connection has disappeared because they've stopped seeing friends.
The idea isn't to analyse everything endlessly. It's to start noticing what's depleted and what might help replenish it. That awareness is a skill in itself.
What About Screens?
Liz was very clear that she isn't a screen-time expert, but her point was useful: screens can be difficult for everyone to put down, and the dopamine-seeking nature of ADHD may make that pull particularly strong. Again, don't make it all about your ADHD teenager. Try family boundaries. Phones away at certain times. A phone box at dinner. And think about what could replace the scrolling, rather than simply removing it.
Don't Make Everything About ADHD
Perhaps Liz's loveliest final message was this:
Don't single them out. Try the Building Block Audit together. Put everyone's phones away. Get everyone moving. Think about sleep, connection and fun as a family.
Your teenager may have an ADHD brain, but not every conversation, boundary or family strategy has to remind them of it.
Sometimes the most supportive thing we can do is simply make something the way our family does things, rather than another thing they have to do because they have ADHD.
