Brain Health in Ontario: Forming an Integrated Approach

The impact of brain disorders

The World Health Organization (2022) defines brain health as the state of brain functioning across cognitive, sensory, social-emotional, behavioural and motor domains, allowing a person to realize their full potential over the life course, irrespective of the presence or absence of disorder.

Maintaining good brain health benefits our general health, well-being, productivity and creativity. However, there are a number of ways for the brain and spinal cord to become altered. Over a lifetime, one in three people will develop a neurological or neurodevelopmental condition, experience mental health challenges, or acquire a brain injury. The various conditions all result in changes to brain function. As such, it is informative to think about these conditions collectively as brain disorders. This broader grouping unifies an otherwise disparate group of injuries, diseases, and conditions, and brings added awareness and attention to the health consequences and care needs of those affected by all disorders of the brain.

One in three people in Ontario are directly impacted by a brain disorder. These brain disorders range from highly prevalent disorders that impact more than 10% of the population like depression and brain injury (traumatic brain injury and concussion), those that impact 1 to 10% of the population including ADHD, stroke, and dementia, to disorders like cerebral palsy or parkinsonism which directly impact less than 1% of the population.

Nearly every person is impacted by a brain disorder with the appreciation that the one-third of individuals do not live in isolation. Not counted in this number is the impact on family and friends, caregivers, co-workers, and society who support and care for these individuals.

*Data was generated by combining health system data from 2019 (Brain Health in Ontario Project) with other prevalence estimates taken from Autism Ontario (2020), Morkem et al. (2020), Centre for ADHD Awareness Canada, and the Canadian Chronic Disease Surveillance System (2019).

The Brain Health in Ontario Project

The Brain Health in Ontario (BHIO) Project was developed by OBI, using the data sets and analytic services available through ICES, to address knowledge gaps and provide insight into the profile of 13 brain disorders in Ontario as of 2019. The brain disorders assessed were:

cerebral palsy - dementia (including Alzheimer's disease) - epilepsy - malignant brain tumour - motor neuron disease - multiple sclerosis - non-malignant brain tumour - parkinsonism - schizophrenia - spina bifida - traumatic spinal cord injury - stroke & transient ischemic attack - traumatic brain injury (including concussion)

Note, other prevalent brain disorders like autism spectrum disorder, ADHD, depression, anxiety, and mood disorders were not possible to measure using health system administrative data and are not included in this project or the following data.

Explore key findings on 13 brain disorders

For each of the 13 disorders assessed in the BHIO project, we explored:

  • age range of people with the disorder
  • sex ratio of people with the disorder
  • how many people are living with the disorder from 2011 - 2019
  • number of new cases identified each year
  • what other brain disorders commonly co-occur
  • overlap with mental health and addictions health system use
  • direct costs associated with health system use
