Can you have ADHD and anxiety at the same time?

Having both conditions at once is common, not unusual

ADHD and anxiety disorders are among the most frequently co-occurring conditions in both youth and adults. Neither diagnosis excludes the other, and a clinician assessing for ADHD is expected to also screen for anxiety, and vice versa, rather than treating whichever symptom is more obvious as the whole picture.

This overlap is well recognized enough that structured ADHD assessment tools built for Canadian practice include anxiety screening as a standard component, not an optional extra a clinician adds only if something seems off.

If you've spent years assuming your restlessness or racing thoughts were purely anxiety, or purely ADHD, it's worth knowing that a combined picture is common enough that clinicians expect to see it regularly, not as a rare or complicated exception.

Each condition can make the other harder to live with

Untreated ADHD can generate real anxiety, missed deadlines, forgotten commitments, and repeated small failures build worry over time, while an anxiety disorder can worsen ADHD-related difficulties by adding rumination and avoidance on top of existing attention and organization challenges. This interaction is one reason people with both conditions sometimes describe their symptoms as feeling more intense than either alone would explain.

For example, someone might avoid starting a task specifically because they're anxious about doing it imperfectly, which then triggers the classic ADHD pattern of last-minute rushing, which in turn creates more anxiety about the outcome. Recognizing this cycle as the interaction of two conditions, rather than a single character flaw, is often a meaningful shift for people who've lived with it for years.

This cycle can also affect sleep, since a mind occupied by both unfinished tasks and worry about them often has a harder time settling at night, which then leaves less capacity the next day to manage either condition well.

A diagnosis is made for each condition on its own criteria

Rather than picking one diagnosis to explain everything, a proper assessment applies the specific criteria for ADHD, developmental history and childhood onset, and the specific criteria for the anxiety disorder in question separately. Both can be confirmed if both are genuinely present, which is a normal and expected outcome rather than an unusual finding.

This matters because a clinician who stops investigating once one diagnosis seems to fit risks missing a second, genuinely present condition, leaving it untreated even after the more obvious one is addressed.

Virtual assessments handle this sensitive history under the same privacy protections as in-person care

Discussing anxiety symptoms, family history, or other sensitive details during a virtual appointment in Ontario is protected under the same provincial health privacy law, PHIPA, that applies to in-person care, according to Ontario's Information and Privacy Commissioner. This means the format of the appointment, video rather than in-person, doesn't reduce the confidentiality protections around what you share.

This is worth knowing for anyone hesitant to bring up anxiety symptoms in detail out of concern about privacy, since the legal protections around your health information are the same regardless of whether the appointment happens in an office or over video.

Treatment usually addresses both conditions, not just one

Because the two conditions interact, a plan that only treats ADHD or only treats anxiety often leaves something unaddressed. Adults in Ontario can access free, publicly funded cognitive behavioural therapy for anxiety through the Ontario Structured Psychotherapy program alongside ADHD-focused care. Related questions people ask include how ADHD is diagnosed when anxiety is also present and what medication approach is typically suggested when both are present. If anxiety ever feels overwhelming, call or text 9-8-8, Canada's Suicide Crisis Helpline, or call 911.

Some people also find ADHD coaching or cognitive behavioural therapy through Finding Focus's therapy program, delivered by a Registered Social Worker for adults in Ontario, useful for building the day-to-day strategies that address the ADHD and anxiety interaction directly, alongside whatever medication plan is in place. Sessions run 50 minutes, starting from $149, paid per visit with no membership required.
