Building Better Brains

Development, Mental Health, and Addiction

Brain Story Video

The Brain Story

The Brain Story is about how brains are built during the early years of life. It is fundamental to our understanding of why some people succeed and others struggle with both physical and mental health problems, including addiction. All teachers, early childhood educators, politicians, family support workers, parents, neighbours, in short: everybody, should know something about brain development.

Are you interested in sharing the brain story in your community?

Brain Architecture

Early experiences build brains

Brain Architecture is a key starting place for understanding the story of early brain development and its consequences for lifelong health. Early positive or negative experiences change the structure and function of our brains; that concept sets the stage for understanding our role as a community in helping kids achieve better lifelong health.

Serve and Return

Positive experiences build strong brain architecture

The interactive serve and return between a child and a caregiver – cooing, making facial expressions, and babbling back and forth – literally builds the architecture of the developing brain. Having a positive, nurturing relationship with a caregiver early in childhood is one of the most important ways to promote healthy social, emotional, and cognitive development. Once we know what kind of experiences build strong brain architecture, we can work together to make sure all families have the support they need to provide those experiences from day to day and from hour to hour.

Executive Function

The “air traffic control centre” of the brain

A child’s behaviour is an expression of executive function skills that develop in specific areas of the brain. We all know that cognitive skills such as arithmetic and reading develop with practice and guidance. But not everyone understands that brain development also includes social and emotional skills, like the ability to pay attention, plan ahead, deal with conflicts, and follow rules. These “executive function” skills also develop through learning and coaching, so it’s important to work with kids and teens to develop the abilities they need to be productive and work well with others. “Air traffic control” is a way of understanding executive function and behaviour as a group of skills that can be developed with adult support in the home, at school, and in the community.


A force that strengthens or weakens brain architecture

In tense situations, the body releases stress hormones as part of its fight-or-flight response. These hormones affect brain architecture in a way that is positive, tolerable, or toxic depending on the frequency and duration of the stress response. Whether or not a stressful even is helpful or harmful depends not just on intensity, but on whether supportive adults are present to buffer the stress response and to teach coping skills.

Positive Stress

Short, stressful events like meeting new people or starting the first day of school are healthy for brain development. They prepare the brain and body for stressful situations later in life.

Tolerable Stress

Tragic, unavoidable events like a natural disaster or losing a loved one aren't good for us. But if supportive caregivers are around to buffer the stress response, these events won't do lasting damage to the brain and body.

Toxic Stress

Ongoing, repeated exposure to abuse or neglect is bad for brain development. If no supportive adults are present to help buffer the stress response, stress hormones will damage developing structures in the child's brain. The result is an increased vulnerability to lifelong physical and mental health problems, including addiction.

Help Your Community Build Better Brains

Sharing the Brain Story with community groups is a great way to raise awareness about early brain development and its connection to adult health. These toolkit materials have been created by the Alberta Family Wellness Initiative (AFWI) to support conversations in professional and public settings.

Become a Brain Story Champion

You can become a Brain Story Champion by presenting these resources in your community. After each presentation, please log your event so we can track our progress.
