1
ADHD is often explained in one sentence.
2
You don't have enough dopamine.
3
So the solution sounds simple.
4
Increase dopamine, take a stimulant, improve focus.
5
And for many people, stimulants can be life-changing.
6
But here's the clinical problem.
7
If ADHD were only a dopamine deficiency, treatment would be straightforward.
8
Give the medication, increase the dose, restore attention, problem solved.
9
But that is not what we see in real life.
10
We see people who focus better, but sleep worse.
11
People who become more productive but also more anxious.
12
People who can start tasks but crash later in the day.
13
People who say the medication works but I feel wired.
14
This is where ADHD treatment becomes more interesting and relevant.
15
Because the aim is not simply to stimulate the brain.
16
The aim is to regulate the system so the person can think, sleep, feel, plan, act, recover, and function.
17
So in this video, I want to explain why ADHD treatment is not just about more dopamine.
18
It's about signal clarity and reducing background noise.
19
It's about sleep.
20
It's about emotional regulation.
21
And it's about knowing when to stimulate and when to calm the system down without the medication.
22
I'm Dr. Sunil Rege, consultant psychiatrist and educator.
23
As someone who's developed over 30 hours of educational material on the academy by psych scene for ADHD-specific training,
24
now used by clinicians, governments, institutions, I've realized one important thing.
25
Is that ADHD requires a broader lens.
26
So let's start off with what ADHD isn't.
27
The common explanation of ADHD is attractive because it's simple.
28
ADHD equals low dopamine.
29
Stimulants increase dopamine.
30
Therefore, stimulants treat ADHD.
31
Now, there is a small piece of truth in this, but applying this formula generically can be a recipe for disaster.
32
Dopamine is involved in a range of functions.
33
In motivation, salience, reward prediction, the ability to learn, effort allocation, and the appropriate selection of action.
34
Noradrenaline is involved in alertness, vigilance, attention and cognition under stress.
35
Both these neurotransmitters play an important role in the frontostriatal systems.
36
And what stimulant medications do is they can improve attention, reduce impulsivity and improve executive functioning.
37
But what's important here is to recognize that they don't do this directly by targeting attention.
38
What they do is that they increase arousal and salience.
39
They increase the brain's ability to tag what's important and therefore help the individual stay with that task longer.
40
That's what stimulants do.
41
But the mistake that often occurs when thinking about stimulants is that more stimulation always means better regulation.
42
That is not how the prefrontal cortex works.
43
The prefrontal cortex works on an optimal Goldilocks curve.
44
Too little and you have the symptoms of inattention, impulsivity, the ADHD construct.
45
Too much and you have cognitive rigidity,
46
inflexibility, hyperarousal and stimulus bound responses where the individual gets distracted by multiple stimuli.
47
So stimulants work best within a range and the optimal level differs from person to person.
48
So the clinical question in treating ADHD is not, how do we push dopamine higher?
49
The better question is, what state is this nervous system in and what does it need to function?
50
So if treatment of ADHD isn't just about stimulation, what is the main aim?
51
You see, ADHD is a regulation issue across multiple systems.
52
Regulation of attention, effort, motivation, emotion, sleep-wake rhythm, action.
53
And this is why ADHD affects so many areas of life.
54
And this is why treatment has to go beyond just increased dopamine because attention, for example, depends on state.
55
And the state that matters most is the underlying state of arousal.
56
Because as I mentioned before, what stimulants do is they enhance this arousal state and thereby increase attention.
57
So if the person is sleep deprived, the arousal is already high.
58
The stimulant may temporarily increase alertness, but it may also worsen the sleep cycle.
59
Similarly, if the person is anxious or hyper aroused, the stimulant may improve task initiation, but also increase internal tension.
60
If the person has emotional dysregulation, the stimulant may suddenly sharpen cognition with the patient saying, my internal chatter has stopped,
61
but may exacerbate anger outbursts.
62
Or if the person is exhausted, overwhelmed, or running on chronic stress,
63
heightened arousal, more stimulation will push them to the opposite pole of the Goldilocks curve.
64
And this may create short-term performance the long-term destabilization, where the crash and burn cycles become more frequent.
65
Now for each of this concept, if you want to go deeper, check out the ADHD playlist here, because each of these concepts,
66
concepts of performance debt, interceptive blindness and burnout,
67
masking, or optimal treatment, I've covered all of these in individual videos, which you can find in the playlist here.
68
So what I'm trying to highlight here is that ADHD treatment needs a sequence.
69
And the first step of the sequence is to understand the state within which the person is operating.
70
Then regulate the system.
71
And the third step is stimulate if needed.
72
And I say this because certain regulation strategies, such as improving sleep itself, acts as a stimulant.
73
More detail again in this video here where you can understand sleep cycles
74
and how to maximize sleep cycles to improve your cognition.
75
So let's think about using stimulants appropriately.
76
We know that stimulants increase dopaminergic and noradrenergic signaling.
77
When prescribed appropriately, they optimize arousal and therefore can improve focus,
78
reduce impulsivity and help the person engage with the task longer.
79
Key word I want to highlight here is arousal.
80
Arousal creates noise.
81
Stimulants increase the signal and reduce the background noise.
82
But if the signal is increased too much, it gets converted into noise simply because the volume's too loud.
83
And when the volume's too loud, that's exactly when patients say, I can focus, but I feel tense.
84
I get things done, but I crash.
85
My sleep's all over the place.
86
In some cases, the patient thinks they're going okay,
87
but the family members are concerned because the individual spends excessive time cleaning or is really irritable and snappy with the kids.
88
So at this point, you might ask, are there any medication strategies to help improve control and to regulate the system?
89
Yes, there are.
90
This is where medications, specifically alpha two agonists, such as clonidine and guanfacine become really, really useful.
91
Again, I've covered this in more detail in the video here.
92
These agents do not increase dopaminergic or noradrenergic neurotransmission.
93
What they do is they can reduce arousal and therefore can support prefrontal regulation,
94
emotional control, impulse control, and sleep.
95
There are subtle differences between the two.
96
Guanfacine is a more selective post-synaptic alpha-2a effect, and therefore they can be helpful to reduce anxiety,
97
impulsivity, emotional reactivity, and provide a certain benefit for cognition.
98
Whilst clonidine is an alpha-2 presynaptic agonist, in simple terms, what it does is it steps on the brake,
99
thereby reducing noradrenologic neurotransmission, which can be really helpful
100
when there are sleep onset issues and sleep maintenance issues because of vivid dreams and nightmares.
101
Because clonidine improves non-REM sleep and can reduce or even treat restless REM sleep.
102
Clonidine is also indicated if there is hyperarousal as part of PTSD or trauma related aspects,
103
in ticks or evening rebound symptoms that occur post-stimulant, clonidine can work really well here.
104
So the key point I want to convey is this, treating ADHD is not about increasing activation.
105
Sometimes it's about reducing the interference, the noise that prevents the prefrontal cortex from functioning properly.
106
A regulated brain can often think better, inhibit better, wait better, choose better, and recover better.
107
As always, when I discuss medication, it's important to recognize this is an educational video only.
108
So none of what I cover here should be construed as medical advice.
109
In clinical practice, I often use a synergy of a stimulant and non-stimulant, which provides optimal regulation.
110
For others, a single medication may be sufficient.
111
The art is matching the treatment to the person's patent.
112
Since we're talking about treatment, let's think about how we translate this into a clinical model.
113
I think of ADHD treatment in phases.
114
Ultimately, it's a lifespan condition, and therefore we need to optimize treatment across the lifespan.
115
There'll be different phases, different environmental demands.
116
So it's not just simply about medication.
117
It's medication plus other psychosocial type lifestyle strategies.
118
So let's look at a practical sequence.
119
And first, clarify the pattern before changing medication or introducing medication.
120
Understand the profile.
121
ADHD is a condition that affects multiple domains.
122
Cognition, activity, emotional hedonics, specifically reward sensitivity,
123
behavioral activation, behavioral inhibition, fight and flight responses, and sleep.
124
So ask the question, what are the main domains affected?
125
Sleep, hyperarousal, rebound, anxiety, executive dysfunction, etc. The word ADHD is not enough.
126
Two people can have the same diagnosis but need different treatment strategies.
127
So as part of the pattern, it's important to formulate.
128
Consider other comorbidities because they will form an important part of noise.
129
The second part of the sequence, stabilize the foundations.
130
Basic aspects, sleep, nutrition, routine,
131
movement, environmental structure, and reducing as much as possible unnecessary noise, arousal.
132
We're not looking at one or the other, lifestyle advice versus medication.
133
It's looking at medication plus lifestyle.
134
Simply because if the context of the environment is chaotic, the medication is going to have to fight harder.
135
And the issue is when we think about fighting harder, it does not simply mean increasing the dose because stress increases arousal.
136
If we increase the dose, we increase arousal and worsen cognition.
137
So we've got to focus on reducing arousal and managing the environment.
138
Third step, think about the targets that you're looking to address with the stimulant.
139
Remember, the goal is not to feel driven.
140
The goal is to improve and regulate attention,
141
task completion, impulse control, and daily functioning without destabilizing sleep, appetite, emotional tone, or relationships.
142
I often say treatment is about the whole day and sleep included.
143
It's really a 24-hour cycle.
144
And that means that dose, timing, formulation, and duration matter.
145
In many cases, a lower dose works better than a high dose.
146
A long-acting medication is preferable than a short-acting medication.
147
Short-acting medications can sometimes be used as short-term augmentation agents.
148
And an important part to consider is that dose adjustments may be needed over time.
149
Other comorbidities may occur and need to be treated over time.
150
The lens is never just ADHD.
151
The fourth step in the sequence, consider regulation-based medication when indicated.
152
If the person has prominent hyperarousal, emotional reactivity, impulsivity, sleep problems, ticks, evening rebound, or even aggression,
153
non-stimulants such as alpha 2 agonists may be worth considering clinically.
154
And this step may come even earlier than the stimulant in some patients.
155
In my practice, I often consider sleep first as a fundamental foundation of psychiatric treatment.
156
Now, both clonidine and guanfacine require specific monitoring, blood pressure, sedation, dizziness, fatigue, timing, all of these aspects need to be monitored closely.
157
So based on what I've said, you might recognize that one or two appointments is really not sufficient to stabilize medication.
158
ADHD is a lifespan condition and requires a lifespan approach.
159
If you're a clinician watching this video, I'd encourage you to look at the academy course, the comprehensive ADHD curriculum.
160
This course bridges the gap between academia and real life practice.
161
The foundation of diagnosis here is a nine-step plan.
162
Applying this nine-step strategy ensures that your diagnostic process and treatment is individualized to your patient.
163
So if there's one thing to remember from this video, it's this.
164
ADHD is not simply a low dopamine state.
165
Dopamine and noradrenaline matter, but the goal is not to push them higher without limit.
166
The goal is regulation.
167
Stimulants can be highly effective, but they work best when sleep, arousal, emotion, and daily rhythm are considered.
168
If the system is already overloaded, more stimulation will simply create more noise without better control.
169
Non-stimulants such as clonidine and guanfacine can be useful in selective patients because they target arousal,
170
impulse control, emotional reactivity, and sleep,
171
not through pushing dopamine, but through other mechanisms that provide regulatory benefits.
172
And don't forget sleep.
173
It's one of the most important treatment targets in ADHD.

Why Practice Speaking with This Video?
This video is a goldmine for english speaking practice—it’s conversational, informative, and packed with natural phrasing that mirrors real-world discussions. Whether you’re prepping for IELTS speaking practice or just want to sound more confident, the clear, deliberate tone of Dr. Rege’s explanation makes it perfect for shadow speech. Shadowing (repeating aloud as you listen) helps you master rhythm, pauses, and emphasis—skills that turn "good" English into "natural" English. Plus, the topic is engaging, so you’ll stay motivated while building fluency!
Grammar & Expressions in Context
Let’s break down 3 key structures to boost your speaking:
- "If ADHD were only a dopamine deficiency, treatment would be straightforward." This second conditional (if + past simple, would + verb) is ideal for discussing hypothetical situations—critical for IELTS tasks. Practice it by replacing "ADHD" with topics like "stress" or "technology."
- "What stimulants do is they increase arousal and salience." The structure "What [X] do is [Y]" adds clarity when explaining processes. Use it to describe how tools (like a shadowing app) work: "What a shadowing app does is it helps you match native speakers’ pace."
- "The aim is not simply to stimulate the brain; the aim is to regulate the system." Parallel structure ("The aim is not…; the aim is…") makes your speech more persuasive. Try it with goals: "My goal isn’t just to learn words; my goal is to use them confidently."
Common Pronunciation Traps
Watch out for these tricky words in the video:
- "Dopamine" (doh-puh-meen): Don’t rush the "meen"—stress the second syllable. Mispronouncing it can confuse listeners in discussions about mental health.
- "Noradrenaline" (nor-uh-dren-uh-lin): Break it into 5 syllables. Practice saying it slowly, then speed up to match the video’s flow.
- "Prefrontal cortex" (pree-frun-tuhl kor-teks): The "pre" is short, and "cortex" rhymes with "corrects." Get this right, and you’ll sound sharp in academic or casual talks.
Remember, shadowspeaks isn’t about perfection—it’s about progress. Hit play, pause, repeat, and let this video guide you to clearer, more confident English!
Grammar in this video
The structures the speaker uses most, with the exact words from the video:
| Structure | In the video |
|---|---|
| Passive voice be + past participle — the focus is on what happens, not who does it | is often explained · is involved · is increased |
| Present perfect have/has + past participle — a past action that still matters now | I've realized · has stopped · I've covered |
| Relative clauses who / which + clause — extra information about a person or thing | people who focus · People who become · People who can |
What is the Shadowing Technique?
Shadowing is a science-backed language learning technique originally developed for professional interpreter training and popularized by polyglot Dr. Alexander Arguelles. The method is simple but powerful: you listen to native English audio and immediately repeat it out loud — like a shadow following the speaker with just a 1–2 second delay. Unlike passive listening or grammar drills, shadowing forces your brain and mouth muscles to simultaneously process and reproduce real speech patterns. Research shows it significantly improves pronunciation accuracy, intonation, rhythm, connected speech, listening comprehension, and speaking fluency — making it one of the most effective methods for IELTS Speaking preparation and real-world English communication.
