-
It is clear, Ticha is extremely impulsive
-
and the influence of his hyper-activity on his sleeping patterns
-
is being researched.
-
But how does Ticha score on the other two main characteristics of ADHD:
-
reaction speed and attention?
-
Ticha is going to Utrecht for a new examination
-
which seems to suit him very well.
-
Good afternoon!
-
I'm having my ADHD examined at the Trimbos Institute:
-
to what extent I have it and how much it influences
-
my thoughts and actions.
-
And I get to smoke a joint for the examination!
-
That I've never experienced!
-
So it'll be fun.
-
Exciting, you know, I find it very exciting.
-
We're going to do the MOXO test.
-
This is a test, actually still being developed,
-
but intended to investigate ADHD-like behaviour.
-
People with ADHD have problems focussing,
-
and maintaining their attention on something.
-
They are easily distracted by external stimuli.
-
They are impulsive and hyperactive, so
-
they react more and more often
-
than a norm group.
-
For you it is a quite simple, but a rather long test:
-
20 minutes.
-
What you have to do is, as soon as...
-
I have to do a test for 20 minutes.
-
When I have the ace of hearts, at the top and at the bottom,
-
it has to be visible top left and at the bottom.
-
And then I have to press the space bar when I see it.
-
I am distracted more and more.
-
You will be distracted by several things
-
coming into the picture, or that you hear.
-
We'll test the volume.
-
That's fine.
-
This means that you can practise now.
-
This is the card.
-
But there it was, and you didn't press the space bar.
-
This is still just practice.
-
OK, I'll start the test.
-
Hey, you woke me up.
-
What's going on? A bank robbery?
-
Money stolen? A fight about the dog?
-
OK, that was it.
-
We'll do another one this afternoon.
-
I think I was quite sharp.
-
That is my answer to the question.
-
I think so. But I think I'll be sharper after the joint.
-
And who can say this?
-
That, for science, you get to smoke
-
a whole thick joint - on television?
-
Of course, for scientific purposes only.
-
It's not something I enjoy doing.
-
It's only to help you.
-
What is interesting about this marijuana is that
-
when you smoke it, you go find yourself in Jamaica immediately.
-
Very enjoyable.
-
Am I allowed to use the bike?
-
I can't stay in one place for so long.
-
I hope they don't kick us out of here.
-
We're almost there, boys.
-
Almost.
-
Then we're going to do the test.
-
And I'm going to do much better than before.
-
Now that I'm stoned, it feels even longer.
-
It's a very boring test.
-
And 20 minutes ...
-
I thought that there would be more impulses, way more ...
-
OK, that was it.
-
I'm going to look at the results, and then
-
I'll discuss them with you.
-
The data is processed.
-
In terms of reaction time and attention,
-
does Ticha really have ADHD?
-
And what happens to his scores when he smokes a joint?
-
Did it work?
-
Yes, we have the results for you, and ...
-
I'm going to show them to you.
-
I think you will be surprised.
-
Because I have the impression than when one looks only
-
at situations in which there are distractions - and it seems to me
-
that these are quite common in your life - then the test
-
seems to indicate that you are suffering from
-
what we call ADHD-like behaviour.
-
Oh, it's not that bad!
-
It's just too much energy.
-
That is absolutely the case.
-
I could quote you on that.
-
As soon as there are distractions,
-
especially an audiovisual combination, we see him struggling.
-
With or without the joint.
-
If you look at what happens when you have smoked a joint,
-
you see your reaction speed decrease dramatically.
-
You said yourself that you thought you would do better.
-
And afterwards you said you felt more focussed.
-
This is not what the test shows.
-
Yes, it's gone.
-
The reaction speed is completely gone.
-
I thought I would do it quite well.
-
But that was not the case.
