Understanding the Surge in Adult ADHD Prescriptions
The recent study highlighting a dramatic rise in new prescriptions for attention-deficit/hyperactivity disorder (ADHD) medications among adults in Ontario has captured significant attention across Canada. Published in JAMA Network Open
Stimulants like methylphenidate (e.g., Concerta, Ritalin) and amphetamines (e.g., Adderall, Vyvanse) are central nervous system medications that enhance focus and reduce impulsivity by increasing dopamine and norepinephrine levels in the brain. The study's focus on new prescriptions underscores a shift toward greater recognition and treatment of ADHD in adulthood, a condition characterized by persistent inattention, hyperactivity, and impulsivity that interferes with daily functioning.
Pre- and Post-Pandemic Trends in Detail
Prior to March 2020, new adult prescriptions totaled around 107,000 over four years. In the subsequent four years, this number more than doubled to over 220,000, coinciding with widespread lockdowns and shifts to remote work.
The data illustrates a clear inflection point: prescriptions dipped briefly at the pandemic's start due to healthcare disruptions but rebounded sharply, facilitated by virtual care. By 2023, 29% of new prescriptions originated from telehealth visits, a negligible factor beforehand. This reflects broader healthcare adaptations but raises questions about diagnostic rigor in remote settings.
| Period | New Adult Prescriptions (Ontario) | Annual Growth Rate |
|---|---|---|
| 2015-2019 (Pre-COVID) | ~107,000 (4 years) | 7% |
| 2020-2023 (Post-COVID onset) | >220,000 (4 years) | 28% |
Demographic Shifts: Women and Young Adults Lead the Rise
Women, particularly those aged 18-44, accounted for the most striking increases. New prescriptions for females aged 25-44 surged 421.3%, while those for 18-24-year-olds rose 368.7%. By 2023, prevalence among females aged 18-24 reached 6.7%, surpassing males at 5.2%. Women now comprise 59% of new adult stimulant users post-pandemic, up from 48% pre-pandemic.
This reversal challenges historical patterns where boys dominated diagnoses due to hyperactive symptoms. Women more often exhibit inattentive ADHD, overlooked in traditional assessments. Pandemic stressors—juggling remote work, childcare, and isolation—likely unmasked these traits, prompting more women in demanding careers, including academia, to seek help.
- Females 18-24: 6.7% annual prevalence
- Females 25-44: 421% increase in new Rx
- Males overtaken in key age groups by 2023
Why the Surge? Pandemic Stress, Awareness, and Access
Lead author Dr. Daniel Myran, a family physician and ICES scientist affiliated with the University of Ottawa, attributes the trend to multiple factors. Increased online content about adult ADHD, proliferation of private virtual clinics, and reduced barriers via telehealth boosted awareness and access.
Greater recognition of ADHD's heritability means parents diagnosed alongside children seek evaluations. For university students and faculty—often in high-pressure environments—these shifts align with burnout reports. Telepsychiatry, while convenient, demands scrutiny to ensure accurate diagnoses.
Concerns Over Overdiagnosis and Medication Risks
While progress in addressing underdiagnosis is evident, rapid growth sparks worries. Dr. Myran cautions: "The size of the increases also raises concerns about mis- or over-diagnosis, which can result in exposure to adverse side effects." Stimulants carry cardiovascular risks, potential mania induction in undiagnosed bipolar cases, and dependency concerns. Ongoing shortages of drugs like Adderall exacerbate access issues, forcing switches or dose adjustments.
Senior author Dr. Yaron Finkelstein from The Hospital for Sick Children (University of Toronto) emphasizes: "Ongoing research and clear clinical guidance are essential." The study couldn't verify diagnostic appropriateness, highlighting a data gap.

Impact on Canadian Higher Education
University students aged 18-24, a key demographic, face heightened ADHD challenges amid academic demands. Research from Canadian institutions like the University of Waterloo shows ADHD symptoms, especially inattention, predict poorer long-term success, with affected students 2-3 times more likely to underperform or drop out.
Post-COVID, ADHD prevalence in postsecondary settings mirrors national trends, complicating retention and performance. For those pursuing faculty positions or graduate studies, unmanaged ADHD can hinder research output and teaching efficacy.
University Responses: Enhanced Supports and Research
Canadian universities have ramped up ADHD resources. Many, including the University of Toronto and University of Calgary, offer peer support groups, accommodations like extended exams, and counseling. Campus Mental Health initiatives provide ADHD-specific workshops, addressing the post-pandemic mental health crisis where 83% of students seek peer support.
- Drop-in ADHD support groups at multiple institutions
- Accessibility services for exam accommodations
- Virtual coaching for executive functioning skills
UCalgary's pharmacogenomics study aims to personalize ADHD treatments via genetic testing, potentially revolutionizing care for students and staff.
Expert Perspectives from Canadian Academics
Dr. Myran notes environmental shifts like screen time may contribute to symptoms, urging balanced approaches. University of Ottawa's involvement underscores higher ed's role in public health research. SickKids' Finkelstein calls for pediatric-to-adult transition guidelines, relevant as students age into workforce roles like lecturer jobs.
Broader research from McMaster and UBC links ADHD to academic hurdles but highlights medication's benefits when appropriately used, improving focus for thesis writing or lecturing.
Navigating Shortages and Seeking Alternatives
Canada's ADHD medication shortages, ongoing since 2022, compound the surge. Patients face delays, generics unavailability, impacting university schedules. Non-stimulant options like atomoxetine or behavioral therapies offer alternatives. Universities recommend holistic strategies: time management apps, study skills workshops, and mindfulness.
