“Dysregulation refers to a disruptive pattern of reactivity in the functioning of your nervous system. When it’s triggered, it causes a change from the default, regulated state of your nervous system into a dysregulated state. In other words, things go “out of whack.” Imagine your regulated state as piano music that someone is playing beautifully. Dysregulation is like a cat that jumps onto the keys while the player keeps playing, overlaying the music with wrong notes that clang with random timing. The piano player can’t focus and stops playing. Likewise, dysregulation is an intrusion of disruptive activity in your nervous system that impedes normal functioning.”
