Dr. Ursula Davatz views psychiatric conditions not as fixed diseases like a liver cirrhosis or a heart attack, but rather as functional diagnoses of the brain. This means the brain’s functioning can change, and there isn’t a clear boundary between one „disease“ and another. She emphasizes that the brain always functions holistically and is interconnected with the body, also directing bodily organs.

Dr. Davatz utilizes Paul D. MacLean’s „Triune Brain“ model to explain brain function. This model divides the brain into three main parts:

  • The emotional brain (limbic system): Represented by the thumb in her hand model, this part is stronger, more reactive, and more sensitive in individuals with ADHS/ADS. It functions somewhat like fluid media (air and water), where movements or „waves“ of excitement can be larger and last longer.
  • The cerebrum (Grosshirn): Represented by the fingers, this is where signals from the emotional brain are ideally processed cognitively and stored as memories without emotions. In ADHS/ADS children, the emotional system remains more strongly connected to the cerebrum, meaning they have to process more impressions, which can make them tired.
  • The reptilian brain (primitive brain): Represented by the wrist, this ancient part of the brain controls vegetative nerve centers such as heart rhythm, breathing, sleep-wake cycles, and motor skills, including the cerebellum.

In individuals with ADHS/ADS, when the emotional brain (limbic system) becomes overloaded, it sends signals both up to the cerebrum and down to the reptilian brain.

  • System Overload / System Overflow: If the emotional brain is under too much stress, it can lead to „System Overload“ and subsequently „System Overflow“. When „System Overflow“ occurs, it can result in thought disturbances. Alternatively, signals can go to the reptilian brain, triggering primitive reflexes like running around, screaming, or the „fight, flight, freeze, or teasing“ responses.
  • Impact of Stress: Due to their highly excitable and reactive emotional systems, individuals with ADHS/ADS are more sensitive to stress. When stressed, their emotional brain creates a larger and longer-lasting „wave“ of excitement.

This heightened excitability means that ADHS/ADS brains require more energy for concentration compared to neurotypical brains. While the brain typically matures by age 25, in individuals with ADHS/ADS, this process may take a bit longer, allowing them to remain „childish“ and creative. However, this sensitivity also means they are more susceptible to illness if raised too restrictively. Over-regulation or attempts to educate them when they are in a state of „high arousal“ (over-excited) are ineffective because the cerebrum loses control, and the reptilian brain takes over with its reflexes. Instead, it’s crucial to allow them to calm down before engaging in rational discussion and to validate their emotions.

Dr. Davatz highlights that the reactions seen in ADHS/ADS individuals are essentially feedback that something is not quite right. This understanding of brain function is central to her approach, which focuses on coaching the environment and caregivers to interact more skillfully with neurodivergent individuals rather than primarily treating the child or teenager directly. She also emphasizes that viewing ADHS/ADS as a „neurodiversity“ or „otherness“ rather than solely a „disability“ acknowledges its potential strengths, such as creativity.
