How early should families plan the handoff from teen ADHD care to adult care?

Start before the last year

Families should usually begin planning the handoff from teen ADHD care to adult care around ages 14 to 16. The Canadian Paediatric Society describes transition as a planned process that begins in adolescence and continues into early adulthood, not a one-time transfer at 18. It also notes that the age when paediatric care must transfer varies by province or program, often between 16 and 19, which is exactly why leaving this until the final months can create gaps in care.

For ADHD, early planning matters because care often includes regular follow-up, school or work documents, and decisions about whether ongoing support will stay with a family doctor, nurse practitioner, paediatrician, or adult ADHD service. If the teen still needs an assessment or a medication review, it is safer to sort that out before the transfer deadline, not after it.

A simple rule helps: if a teen is old enough to talk about how ADHD affects school, work, sleep, driving, routines, and relationships, they are old enough to start learning how adult care works. Families do not need to step back all at once. The goal is a gradual shift from parent-led care to shared care, then to teen-led care.

Use milestones, not vague plans

The handoff works better when families use specific milestones. General advice like "we’ll deal with it later" often turns into a rushed search for records, referrals, or prescriptions.

If the teen has anxiety, depression, substance-use concerns, or thoughts of self-harm along with ADHD, planning may need to start even earlier because adult services can be split across different programs. If anyone needs help now, call or text 9-8-8 in Canada or call 911 in an emergency.

Keep these records before 18

The most useful transition tool is a small, updated record set the teen and family can actually find. Adult providers often need past information to understand what has already been assessed, what has helped, and what still needs work.

• A one-page health summary: diagnosis, other health conditions, allergies, current clinicians, pharmacy, emergency contact.
• The original ADHD assessment report, if there is one, plus any psychoeducational testing or consultant letters.
• A current medication list with doses, timing, past trials, side effects, and what monitoring has been done.
• Recent follow-up notes or a transfer summary from the current prescriber or clinic.
• School accommodation documents that may still matter for post-secondary planning, if relevant. For province-specific school supports, link to the school-support page rather than rebuilding that guidance.
• Copies of standard letters already paid for or submitted, such as diagnosis letters or healthcare-provider reports, if the family has them.
• A list of community supports: therapist, coach, counsellor, family doctor, walk-in clinic, campus clinic, or local crisis resources.

This record set does not need to be fancy. A paper folder plus a phone note can be enough if it is current. CAMH’s adult ADHD assessment guidance notes that assessment commonly includes rating scales, clinical history, and collateral information, so old reports and a clear timeline can make the first adult visit more efficient.

Build self-management before 18

Before age 18, the teen should start practising the basic tasks adult care expects. The handoff is smoother when the young person can do more than simply attend the appointment.

• Name their diagnosis and describe how symptoms show up at school, work, home, and socially.
• Know the names and purposes of their treatments and supports, including possible benefits, risks, and side effects of stimulant medications or non-stimulant options discussed with their clinician.
• Bring or upload forms, reports, and symptom updates before a visit.
• Book, reschedule, and attend appointments, including virtual visits.
• Request prescription renewals early enough and know what to do if a refill is running low.
• Track sleep, appetite, mood, school performance, work demands, and side effects between visits.
• Use one system for reminders, tasks, and calendars that works for them.
• Understand privacy basics, consent, and when parents may or may not be included in visits.

This does not mean parents stop helping. It means parents shift from doing everything to coaching. A good visit near age 17 might include the parent for part of the appointment, then private time for the teen, then a brief shared wrap-up. That supports autonomy without removing family support too quickly.

If families are also sorting out whether ADHD is the full explanation for current struggles, what is the difference between adult ADHD and executive dysfunction from stress? may help frame the questions to bring into adult care.

Aim for no gap in care

The main goal is to avoid a break in care during a period when school, work, moving, and changing routines already make ADHD harder to manage. A planned handoff lowers the chance that the teen turns 18 with no follow-up booked, no records in hand, and no clear prescriber or clinic.

Ask the current clinic four direct questions by the year before transfer: when care ends, what records can be released, whether a transfer summary can be provided, and which adult follow-up route makes sense for this teen. In Canada, adult ADHD assessment and management may happen in primary care or specialty settings. CAMH notes that screening and assessment tools used in adult care include the Adult ADHD Self-Report Scale and the Weiss Functional Impairment Rating Scale, and it points clinicians to CADDRA-based resources for structured adult assessment.

If the teen may need therapy support during or after transition, non-drug supports can still matter. CADDRA’s practice guidance includes psychosocial approaches such as cognitive behavioural therapy as part of comprehensive ADHD care planning.
