What causes seizures in dogs?Įxcessive excitation in the brain resulting in a seizure can happen due to the following causes: Seizures occur when there is imbalance in these mechanisms, favoring sudden excitation and increased firing of neurons. Normal neuronal activity represents a healthy balance between excitatory and inhibitory influences. Neurotransmitters may excite or inhibit other neurons. The cerebral cortex is made up of a large number of neurons that communicate with each other via chemical messengers called neurotransmitters. Seizures always indicate dysfunction in the forebrain (the cerebral cortex).
