Considering both the personal and societal tolls of brain disorders, the Ontario Brain Institute (OBI) and the Institute for Clinical Evaluative Sciences (ICES) partnered to create a comprehensive snapshot of individual brain disorders throughout Ontario. The report encompasses 13 brain disorders and gives estimates for:

  • How many people are living with each disorder and their population data, such as age and sex
  • The number of new cases identified each year
  • An overview of direct healthcare costs associated with each disorder

As a new resource, this report was created with the following objectives:

  • To estimate the prevalence and incidence of brain disorders from population-based health administrative data
  • To provide an overview of costs associated with all publically provided health care services used by individuals with brain disorders
  • To present evidence to inform program and resource planning, policy and decision-making regarding brain disorders in the Ontario health system

As a group, the brain disorders included in this report demonstrate some of the breadth and diversity of conditions affecting Ontarians. Although those included in this report are only a subset of the hundreds of brain disorders, they represent many of the most common and impactful disorders affecting the healthcare system and society. There are many conditions missing, including highly prevalent disorders such as autism, depression, and addiction, but over time methods will be developed to measure these as well.

This report offers the first baseline of that critical information. Its numbers are likely conservative since they aren’t taken from patient or doctor surveys, nor from self-reporting, but from health administrative data collected every time someone interacts with their doctor or visits a hospital.

We hope this report provides valuable information to the public, policy makers, advocacy groups, and the media.

Take a look at some of the data featured in the report through these 13 infographics.



In Ontario:

  • The number of people living with epilepsy equals the population of Pickering?
  • 36% of people with cerebral palsy are 17 or younger?
  • Women represent about 65% of the population living with dementia and Alzheimer’s?
