How does trauma affect neuroplasticity?

Trauma has a significant impact on neuroplasticity, especially in children. Andrew Huberman explains that children who have experienced trauma or significant stress often find it difficult to engage in play, which in turn hampers their ability to access neuroplasticity later in life. This inhibition is particularly linked to high levels of adrenaline, which blocks the circuits that generate play behavior. Trauma and stress essentially suppress the neural circuits that could otherwise help in facing the challenges and engaging freely in playful activities, which are crucial for neuroplastic development 1.

However, Dr. Huberman also highlights that this effect is not permanent. There are existing trauma therapies, such as EMDR, exposure therapy, cognitive behavioral therapy, ketamine treatments, or transcranial magnetic stimulation, which can be effective. These therapies often involve re-engaging in “play” at a more neurobiological level to explore different emotional experiences tied to the traumatic events, thereby helping to reopen the windows of plasticity and allow healing and developmental growth 1.
