What Is The Concept Of The Upstairs Versus Downstairs Brain When Treating Children With Autism?

What is the concept of the upstairs versus the downstairs brain when treating children with autism?


Upstairs vs. Downstairs Brain

  • Tantrum: (Upstairs Brain)
    • Conscious choice
    • Strategic and manipulative
    • Can reason, make choices
    • Emotions under conscious control
    • STOP when demands are met
  • Sensory: (Downstairs Brain)
    • Flood of hormones
    • Over-ride conscious choice
    • Loss of body control
    • Can NOT be reasoned with
    • Not capable of choices

In the brainstem, our responses are reflexive. When something happens in our bodies, the reflex says, "Get to safety, fight, flight, or freeze.” That is the downstairs brain. A flood of hormones, adrenaline, and cortisol comes in and overrides any conscious choice. When a child is in the downstairs brain, they cannot be reasoned with because it is a hormonal response. Until those hormones are reabsorbed, it is difficult to reason with anyone in the downstairs brain. Let's say your worst fear is snakes. If you were in a small room with boa constrictors, I think you might have a hard time concentrating or having any rational thoughts. Your downstairs brain would be responding in that situation. It is chemically-driven, and there is the minimal capability for higher-level thinking.

The cortex is where connections are made from the lower brain to the upper brain. The hippocampus is located in the cortex, and it is where memories are created and stored. Therefore, we can focus and process effectively when the information is in the cerebral cortex. This is where and when we can make those conscious choices.

When a child comes to you for therapy, understand the child is stuck in the downstairs brain, and your goal is for him to think effectively and make good choices. However, they will not be able to do that if they are in the downstairs brain. You are already setting them up for failure.

Drawing of a sailboat on water heading to rocks

I adapted this image from Dr. Daniel Siegel's and Tina Payne Bryson's book, "The Whole-Brain Child." Let's just say there is no wind; therefore, we have to use our rows. We are sitting in the sailboat, and the wind starts up. We may think, "Oh, thank goodness there's the wind." However, the wind starts to blow us toward the rocks. 

Think about how our children with autism would react by being in that boat. They are paddling and catching a nice breeze. When that breeze picks up, or something happens that is unpredictable in their lives, they are going towards rigidity (rocks). At that point, they want to control everything as they are heading towards that wall. To maintain control, they use routines or actions that help them to maintain organization. Sometimes, they head towards the open ocean (or uncharted water), which is very unpredictable. In that case, they need to row back towards a safe, calm pathway of comfort. They are constantly rowing between chaos and the solid, rigid wall. They become exhausted in rowing so hard that they eventually become tired. I think that is where a lot of our children are right now.

Children often struggle with fidgeting, attention deficits, and immature motor patterns which manifest themselves through frustration, sensory, and behavior issues. The optimal function of our bodies occurs when our sensory and motor systems are strong and able to adapt to the demands of the environment. Lack of movement opportunities and the use of electronic devices at a young age both affect the development of patterns used in the occupation of children. Occupational therapists can easily build-in assessment of body and segmental movement and posture. This session provides strategies for assessment and introduces treatment ideas for using movement to improve performance in occupation.
