Neurons are cells that exchange electrical impulses through chemical signals in the form of neurotransmitters. These neurotransmitters then either send or stop the messages, neuron to neuron across gaps called synapses, throughout the brain. There are two types of neuron: those that form excitatory synapses and those that form inhibitory synapses. A seizure develops when there are simultaneous hyperexcitation and hyper synchronization of a neuronal network. Seizures are episodes of paroxysmal neurological dysfunction due to abnormal and excessive neuronal discharge, which results in a sudden change in behavior, sensory perception, or motor activity, either with or without impairment of consciousness (Spray 2015).

The symptoms include involuntary twitching of the muscles, changes in the vision,
