This video tour* of the brain shows how signals are sent through the nervous system, what causes seizures, and how Keppra can help. As you will see, Keppra works in a way that is unlike any other medication because it affects a site in the brain that no other medicine is shown to affect.
Why Keppra Is Different
The billions of nerve cells (called neurons) that make up the brain communicate with one another through a finely tuned system of electrical and chemical signals. In some people parts of the brain’s communications network can become unstable. When that happens, the orderly flow of messages between neurons may grown in to an uncontrolled storm of activity—known as a seizure. Keppra helps reduce the frequency of seizures and may do this by targeting tiny structures located inside the neuron called vesicles. These structures may help control the flow of signals from one neuron to the next. No other epilepsy medicine has been shown to target vesicles to help control the flow of signals from one neuron to the next.
*This depiction is a hypothesized representation of the mechanism of action of Keppra based on available data; many aspects of the neurotransmission process and many aspects of precisely how Keppra works to control seizures remain unknown.
