Dysregulation

Dysregulation refers to a loss of stable control within a biological system over time. It describes how a system behaves — its reactivity, timing, and ability to return to baseline — rather than a lack of effort, weak character, or poor self-discipline. Rather than maintaining steady, well-timed responses, a dysregulated system may: become overactive/underactive, be too easily triggered/ slow to recover, remain active longer than needed, shift unpredictably between states, or become poorly coordinated with other systems. In mental health, dysregulation is often more important than absolute levels. The issue is not simply too much or too little of a signal, but how that signal is generated, sustained, and brought back into balance over time. In bipolar disorder, dysregulation can affect multiple systems at once — including mood, energy, sleep, stress response, and motivation. Feedback mechanisms that normally fine-tune these processes may be less efficient or more sensitive, leading to shifts that unfold across hours, days, or longer periods. Also see Regulation
