kindling effect
The neurobiological phenomenon where repeated episodes of mood disorders become progressively easier to trigger and more severe.
Full Definition
The kindling effect, originally described in epilepsy research, refers to the process by which repeated sub-threshold stimuli eventually produce full-blown episodes with less provocation. In psychiatric medicine, this concept explains how mood episodes in bipolar disorder and recurrent depression may become more frequent, severe, and autonomous over time. Early episodes often require significant stressors to trigger them, but later episodes may occur with minimal stress or even spontaneously. This phenomenon underscores the importance of early intervention and consistent mood stabilization to prevent the progression of mood disorders. The kindling model also helps explain why maintenance treatment becomes increasingly important as patients experience more episodes.
