Adult ADHD in British Columbia: Signs, Late Diagnosis, and How to Get Assessed

Adult ADHD in British Columbia: Signs, Late Diagnosis, and How to Get Assessed

Contributed by Patricia on July 20, 2026

Maybe it is the feeling of being smart and capable and still, somehow, always running behind. Maybe it is a lifetime of being told you are not living up to your potential, or the exhaustion of holding it together in ways nobody else seems to notice. Or maybe someone close to you was recently diagnosed, and their description of what it feels like inside their head sounded uncomfortably familiar. For a lot of adults, the road to asking "could this be ADHD?" starts with one of these moments, not with a headline.

If that sounds like you, you are not overreacting, and you are not imagining a problem where none exists. You are also not alone in asking the question right now: a growing number of adults across British Columbia, especially women, are getting an ADHD diagnosis for the first time well into adulthood.

Short answer: In British Columbia, adults can be assessed for ADHD by a registered psychologist, and a physician referral is not required to book. The process involves an intake conversation, standardized rating scales, a structured clinical interview covering both childhood and adult functioning, and a written diagnostic report. At Pacific Maple Psych Centre, adult ADHD assessments typically begin within one to seven weeks of booking. You can request an appointment directly through our psychological assessment page.

What Adult ADHD Actually Looks Like

The image most people carry of ADHD, a child who cannot sit still and blurts out answers in class, describes only one presentation of the condition, and it is the one that is easiest to spot from the outside. Adult ADHD, and ADHD in women and girls specifically, tends to look different, which is a major reason it goes unrecognized for so long.

Common signs of adult ADHD include:

None of these signs on their own confirms ADHD. Many overlap with anxiety, depression, or simply the demands of a busy life. That overlap is precisely why a proper assessment, rather than a self-checklist or a social media video, matters.

Why So Many BC Adults Are Being Diagnosed Later in Life

A few overlapping factors explain the pattern the BC data shows.

Masking, Especially Among Women

Women with ADHD are more likely to present with inattentive symptoms, such as distraction, forgetfulness, and disorganization, than with the hyperactive or impulsive symptoms more commonly seen in boys. Inattentive symptoms are quieter and easier to overlook. On top of that, many girls grow up absorbing social expectations to appear organized, agreeable, and in control, which pushes them toward masking rather than being noticed and referred for assessment. That effort to mask can hold up for years, sometimes decades, until the coping strategies stop being enough.

The Pandemic Removed External Structure

Many adults with previously undiagnosed ADHD had, without realizing it, been relying on external scaffolding: commutes with fixed start times, in-person supervision, coworkers nearby to notice a missed deadline, a school or office schedule imposed from outside. When the pandemic dissolved that structure, symptoms that had been quietly managed for years became suddenly, undeniably disruptive. The dramatic jump in diagnoses right as the provincial state of emergency ended is consistent with this explanation.

Reduced Stigma and Greater Awareness

Public understanding of what ADHD actually looks like in adults, as opposed to the childhood stereotype, has expanded considerably in recent years. As more people encounter accurate descriptions of adult and female ADHD presentations, more of them recognize themselves in it and seek out an assessment they might not have considered before.

Frequent Misdiagnosis Along the Way

It is common for adults, and particularly women, to be treated for anxiety or depression for years before ADHD is identified as an underlying factor. Those conditions often coexist with ADHD, and treating them alone without addressing the attentional piece can leave someone still struggling despite doing everything a previous treatment plan asked of them.

The Numbers Behind What You Might Already Suspect

If it feels like you are hearing about adult ADHD, and adult diagnosis, more than you used to, that is not just a perception. A population-based study published in The Lancet Regional Health – Americas in September 2025 examined linked administrative health data for adults across British Columbia between January 2013 and November 2023, and the numbers are striking.

Before the pandemic, the average rate of newly diagnosed adult ADHD in BC sat at 8.8 cases per 100,000 people each month, a relatively stable baseline. During the pandemic itself, that rate climbed to 19.2 per 100,000. But the more striking shift happened afterward: when the provincial state of emergency ended in mid-2021, the monthly diagnosis rate jumped by more than 107% in a single month, then continued climbing. In the years since, the post-pandemic average has settled at 34.8 cases per 100,000 monthly, a nearly four-fold increase over pre-pandemic levels.

Just as notable is who is driving that increase. The researchers found that diagnosis rates grew faster among women than men throughout the study period, to the point where rates in women eventually surpassed those in men entirely. This matches a broader pattern researchers have documented internationally: ADHD has historically been studied, and diagnosed, using a template built around how the condition tends to present in boys. Many women simply were not recognized under that template, sometimes for decades. If you spent years wondering why your version of "distracted" or "disorganized" never quite matched the picture in your head of what ADHD was supposed to look like, this is a large part of why.

What a Formal ADHD Assessment Involves

A thorough adult ADHD assessment is more involved than a questionnaire, and that is by design. ADHD shares symptoms with several other conditions, so a careful process helps ensure the diagnosis, or the ruling out of one, is accurate.

At a general level, the process usually includes:

  1. An intake conversation to understand your current concerns, history, and goals for the assessment.
  2. Standardized rating scales completed by you, and sometimes by someone who has known you since childhood, to capture symptoms across settings and time.
  3. A structured clinical interview covering both your current functioning and your developmental history, since ADHD is a lifelong pattern rather than something that begins in adulthood.
  4. Screening for co-occurring conditions such as anxiety, depression, and learning disorders, which can overlap with or be mistaken for ADHD.
  5. A written report summarizing the findings, clarifying whether diagnostic criteria are met, and outlining recommendations for treatment, accommodations, or next steps.

A registered psychologist can conduct this full diagnostic assessment and provide a formal report. If medication becomes part of your treatment plan, that piece is prescribed by a physician or psychiatrist, so many people coordinate their assessment results with their family doctor once the report is complete.

A note on next steps: An ADHD diagnosis, whenever it arrives, does not erase the years spent managing without one. Many adults describe a mix of relief and grief after finally being assessed: relief at finally having language for a lifelong pattern, and grief for the years spent believing the difficulty was a personal failing rather than a treatable, well-understood condition.

Common Questions About Adult ADHD in BC

How do I get tested for ADHD as an adult in BC?

Adults in British Columbia can book an assessment directly with a registered psychologist, and a physician referral is not required to start the process. The assessment includes an intake conversation, standardized rating scales, a structured interview covering childhood and current functioning, and a written report. At Pacific Maple Psych Centre, adult ADHD assessments typically begin within one to seven weeks of booking through our psychological assessment page.

Has adult ADHD diagnosis actually increased in British Columbia?

Yes. A population-based study using linked BC administrative health data from 2013 to 2023 found that newly diagnosed adult ADHD rose from a pre-pandemic average of 8.8 cases per 100,000 people monthly to a post-pandemic average of 34.8 per 100,000, a nearly four-fold increase. The rate of increase was faster among women, whose diagnosis rates eventually surpassed those of men.

What does ADHD look like in adults, compared to children?

Childhood ADHD is often associated with visible hyperactivity. In adults, it more often shows up as internal restlessness, chronic time blindness, difficulty starting or finishing tasks, disorganization, emotional reactivity, and a pattern of working much harder than others to reach the same result. Many adults, especially women, mask these symptoms for years before seeking assessment.

Why are so many women being diagnosed later in life?

Women are more likely to present with inattentive symptoms than hyperactive ones, which are easier to overlook or misattribute to anxiety or depression. Many also develop strong masking strategies through childhood and early adulthood, delaying recognition. The loss of external routine during the pandemic, combined with growing public awareness of what adult and female ADHD actually looks like, has led many women to recognize the pattern in themselves for the first time.

If parts of this article felt familiar, whether it is the constant mental to-do list, the exhaustion from keeping it together, or a lifelong sense of working harder than everyone around you for the same result, a formal assessment can offer real clarity. Pacific Maple Psych Centre offers adult ADHD assessments in Vancouver, typically starting within one to seven weeks of booking.
