What ADHD actually is

Attention-deficit/hyperactivity disorder is a neurodevelopmental condition, which means it affects how the brain develops rather than being something a person picks up along the way. It shows up in two broad clusters: inattention — difficulty sustaining focus, organising, remembering and finishing things — andhyperactivity and impulsivity — restlessness, difficulty waiting, and acting or speaking before thinking it through. Some people have mostly one cluster, some have both.

Two things distinguish ADHD from ordinary distraction. The pattern ispersistent, present from childhood rather than appearing during one stressful year; and it is pervasive, showing up across several areas of life rather than in one difficult job or one difficult classroom. It also has toget in the way of school, work, relationships or daily functioning. A busy week is not ADHD. A decade of the same difficulties across every setting might be.

Signs of ADHD in adults

Adult ADHD often looks less like the hyperactive child stereotype and more like a quiet, exhausting struggle with getting things done. Commonly reported experiences include:

• Reading a page or sitting through a meeting and absorbing nothing
• Starting projects with enthusiasm and stalling before the boring final details
• Chronic lateness, missed deadlines and forgotten appointments despite genuinely caring
• Losing keys, phones, wallets and documents repeatedly
• A restless internal motor that makes sitting still or unwinding uncomfortable
• Interrupting, finishing other people’s sentences, or blurting out thoughts
• Being called lazy, scattered or unreliable while working harder than everyone around you

Many adults reach a diagnosis only after their own child is assessed, or after years of being treated for anxiety or depression that were partly downstream of undiagnosed ADHD.

Signs of ADHD in children

In children, the same underlying difficulties show up against the structure of school and family life. Parents and teachers often notice:

• Careless mistakes in homework, or work that is unfinished rather than wrong
• Not seeming to listen even when spoken to directly
• Losing school materials constantly and needing reminders for every routine
• Leaving their seat, fidgeting, climbing or running when expected to stay put
• Talking a great deal, interrupting, and finding it hard to wait their turn
• Friendship difficulties that stem from impulsiveness rather than unkindness

Two cautions matter here. First, these behaviours are normal in small amounts at every age — frequency and impact are what count. Second, a child can be bright, capable and academically fine and still have ADHD; inattentive presentations in particular are missed for years, especially in girls.

What this self-check can and cannot tell you

It can tell you whether the pattern you are describing resembles the one clinicians look for, and whether a full assessment is a reasonable use of your time and money. That is genuinely useful, and it is what screening instruments are designed for.

It cannot diagnose ADHD or rule it out. It sees only a handful of answers from a single point in view. It knows nothing about your developmental history, your sleep, your thyroid, your mood, your medication, or how you were as a seven-year-old. A clinician weighs all of that, which is precisely why a diagnosis takes a consultation rather than a questionnaire.

How this self-check is scored

Both questionnaires and both scoring thresholds are published, and we have not adjusted either of them.

Adults — WHO ASRS-v1.1 Part A

Six questions. On the first four, an answer of Sometimes, Often orVery Often counts as one point on questions one to three, while question four counts only from Often. On the two hyperactivity questions, only Often orVery Often counts. A total of4 or more out of 6 is the point at which symptoms are considered highly consistent with adult ADHD and further clinical evaluation is warranted.

Children 6–17 — NICHQ Vanderbilt Parent Rating Scale

Eighteen symptom questions, nine on inattention and nine on hyperactivity and impulsivity, each rated Never, Occasionally, Often or Very Often. An answer of Often or Very Often counts. The threshold is6 or more counted items within a single domain, plus at least one area of daily life — school, family, friendships or organised activities — rated as somewhat of a problem or problematic. Both parts are required, because a diagnosis needs functional impact and not symptoms alone.

What a real ADHD assessment involves

An assessment is a structured conversation, not a test you can fail. A psychiatrist or clinical psychologist will typically take a developmental history going back to early childhood, ask how the difficulties play out across work or school, home and relationships, screen for the conditions that imitate or accompany ADHD, and review school reports or family recollections where those are available. For a child, input from school is normally part of the picture. Rating scales like the ones on this page are used inside that process as one input among several — never as the deciding factor.

Conditions commonly mistaken for ADHD

This is the single most important reason not to treat a screening score as an answer. Poor concentration, restlessness and forgetfulness are produced by a long list of other things, many of them very treatable:

• Anxiety disorders — worry consumes the same attention ADHD needs
• Depression — blunts motivation, memory and concentration
• Sleep disorders, including sleep apnoea and chronic sleep deprivation
• Thyroid problems, anaemia and vitamin deficiencies
• Trauma and chronic stress, which look strikingly like ADHD in children
• Learning disorders such as dyslexia, where avoidance is mistaken for inattention
• Hearing or vision problems, a routinely missed cause in young children
• Substance use and some prescribed medications

Several of these can also coexist with ADHD, which is another reason the sorting has to be done by a clinician.

How to get assessed in India

An ADHD assessment is carried out by a psychiatrist or a clinical psychologist. For a child, a child and adolescent psychiatrist is the right specialist. In-person waiting lists can run to months in many Indian cities, which is where an online consultation helps: on Medeze you can book a video consultation with an internationally-trained psychiatrist or clinical psychologist directly, without a referral and without intake forms.

Two practical things make a first appointment far more productive. Print the summary from this self-check and bring it. And bring anything that documents the early years — school reports, report cards, or simply a parent or sibling willing to describe what you were like as a child.
