Kindling: Definition, History, and Characteristics
Kindling is a term used to describe the rapid and progressive increase in the intensity of a seizure, or more generally, behavior associated with epilepsy, following successive episodes of a seizure. This phenomenon is thought to be the result of a process of cumulative neuroplasticity, involving the sensitization of neurons to the seizure-inducing stimulus. Although the exact mechanism of kindling is still unknown, it has been extensively studied over the years and has been suggested to play an important role in the development of epilepsy.
Definition
Kindling is used to describe a phenomenon which occurs when a seizure, or behavioral response associated with epilepsy, increases in intensity following successive episodes. It is thought to be the result of a process of cumulative neuroplasticity, where neurons become increasingly sensitive to the stimulus that is inducing the seizure or behavior. This phenomenon has been observed in both animal and human studies and is thought to be a major factor in the development of epilepsy.
History
The concept of kindling was first introduced by Graham Goddard in 1965, who observed that the intensity of seizures in rats increased with successive episodes. Since then, it has been extensively studied in both animal and human models, and has been suggested to play an important role in the development of epilepsy.
Characteristics
Kindling is thought to be a result of an increased sensitivity of neurons to the seizure-inducing stimulus. This is thought to be due to the process of cumulative neuroplasticity, where neurons become increasingly sensitive to the stimulus with successive episodes. The mechanism of kindling is still not fully understood, however, it is thought to play an important role in the development of epilepsy.
