Description

Epilepsy is the most common neurological disease comprises a heterogeneous group of

disorders, characterized by recurrent and unprovoked seizures due to the huge electrical

discharges of large synchronized neurons. This hypersynchronous neuronal activity

produces sustained action potential and repolarisation followed by hyperpolarisation,

designated as Paroxysmal Depolarization Shift (PDS), as illustrated in Fig. 1.1. This

abnormal activity changes the frequency and amplitude characteristics of the normal

EEG and produces sustained oscillations with high amplitude and low-frequency spikes

and slow-wave complexes. This huge potential affects the normal function of the

neuronal network which leads to the loss of consciousness and involuntary body

movements.


The cerebral cortex of the brain consists of many layers of neurons that are

responsible for action potential propagation. There are two types of neurons named

the Principal or Projection neurons and the Inter neurons or local neurons. The

principal neurons are producing excitatory synaptic potential and the inter neurons

produces inhibitory synaptic potential.


In the neuronal network connection, both neurons are interconnected and the response of these neurons are summed up to

activate the neighbour neurons. The inter neuron is connected with the projection

neuron and provides feed-forward inhibition; The projection neuron is connected with

inter neuron and then the inter neuron induces feed-back inhibition on projection

neuron. Thus the combined activity of these two neurons control the synchronous

activity of large neurons population. Moreover the inhibition and excitation of neurons

are the electro-chemical processes.

Seizure may develop as a result of inheriting a mutation in a molecular mechanism

that regulates neuron behavior, or organization of neuronal network. Alternatively, it

may develop as a result of brain trauma such as a severe blow to the head, a stroke, a

cerebral infection, or a brain malignancy. The symptomless gradual transformation

from normal neuronal network to abnormal neural network is the period called as

silent period. During the silent period, the changes occur in the organization of

axons, loss of specific neuron (in particular inter-neurons and projection neurons

driving inter-neurons), sprouting of axons to elicit large population of neurons and

voltage-gated and ligand-gated channels property changes. This extensive change in

synchronisation results permanent changes in the physical and biochemical structure of

brain cells.
