For decades, ADHD diagnosis has relied heavily on what patients say about themselves.

And that is precisely where the problem begins.

• Memory is imperfect
• Insight varies
• Symptoms overlap with anxiety, depression, personality traits
• And at times, symptoms may be unintentionally or intentionally exaggerated

In fact, modern research highlights that adult ADHD diagnosis is particularly vulnerable to subjective bias, making accurate identification challenging.

This is why psychiatry is now moving toward objective, multimodal diagnostic models.

The Shift: From Self-Report to Measurable Psychiatry

At institutions like the National University of Singapore, researchers have already demonstrated a new model of ADHD diagnosis that integrates:

• Clinical interview
• Questionnaires
• Objective tests (brain-based + behavioural)

Their approach combines:

• Brain function measurement
• Eye movement tracking
• Continuous performance testing

— all alongside traditional psychiatric evaluation.

Why?

Because no single method is enough.

Each modality captures a different layer:

• Subjective experience
• Behavioural performance
• Neurophysiological function

And when combined, diagnostic accuracy improves significantly.

What We Have Brought to Chennai

At Apollo Clinic Velachery, this multimodal, objective framework is now clinically implemented, adapted to real-world psychiatric practice.

Not as a replacement for clinical judgement —
but as a reinforcement of it.

Step 1: Structured Clinical Interview (The Foundation)

A detailed, structured clinical interview

This includes:

• Developmental history (childhood onset)
• Functional impairment across settings
• Academic / occupational trajectory
• Comorbidities (anxiety, depression, substance use)
• Personality patterns

We also apply:

• DSM-5 / ICD-11 criteria
• Standardised rating scales

👉 This ensures that diagnosis is clinically valid and guideline-based

But here is the key shift:

We do not stop at self-report.

Step 2: Continuous Performance Test (CPT) – Measuring Attention Objectively

CPT evaluates:

• Sustained attention
• Impulsivity
• Reaction time variability

Patients cannot “fake consistency” here.

Typical ADHD patterns include:

• Increased commission errors
• Missed targets
• Fluctuating reaction times

These are quantifiable markers, not opinions.

Step 3: QEEG – Looking at Brain Function

QEEG provides:

• Objective mapping of brain activity
• Insights into frontal lobe function
• Network-level dysregulation

Research shows that neurophysiological tools like EEG and fNIRS can enhance diagnostic differentiation and monitoring, especially when combined with clinical assessment.

This helps answer critical questions:

• Is this ADHD or anxiety?
• Is this depression-related cognitive slowing?
• Is this medication effect?

Why This Matters: Eliminating False Positives

One of the concerns raised even in international research is:

👉 Overdiagnosis due to exaggerated self-reporting

There is documented concern that individuals may:

• Overestimate symptoms
• Seek diagnosis for performance enhancement
• Or misattribute other issues to ADHD

A purely interview-based system may struggle here.

But a multimodal system:

• Cross-validates findings
• Identifies inconsistencies
• Improves diagnostic confidence

Single Visit — Not Shortcut, But Integration

The NUS model demonstrates that a full ADHD assessment can be completed in ~90 minutes when structured properly.

Similarly, by integrating:

• Clinical interview
• CPT
• QEEG

👉 We are able to arrive at a high-confidence diagnosis within a single visit

This is not:

• Rushed
• Superficial
• Or shortcut-based

This is:

Parallel processing of multiple diagnostic layers

From Diagnosis to Treatment (Same Day, When Indicated)

Once diagnosis is established:

• A structured formulation is made
• Comorbidities are addressed
• Treatment is initiated

Including medications like Methylphenidate
— prescribed strictly as per regulatory guidelines

Precision Psychiatry — Now a Reality

What was once confined to research labs in Singapore is now:

👉 Clinically available in Chennai

A model where:

• Psychiatry is not just descriptive
• But increasingly measurable, objective, and precise

Who Should Consider This?

• Adults unsure about ADHD diagnosis
• Patients with partial / unclear previous assessments
• Individuals with overlapping anxiety or depression
• Students and professionals needing clarity before treatment
