Epilepsy (seizure disorder, fits) is a neurological disorder characterized by recurrent instances of seizure or tremors.Seizures occurs when the electrical discharges of a large number of neurons become abnormally linked together, creating a storm of electrical activity in the brain. This resulting from an imbalance between the excitatory and inhibitory processes in the brain, which could be either decrease the inhibitory neurotransmission which is primarily mediated by gamma-amino butyric acid (GABA), or increase the excitatory neurotransmission which is primarily mediated by glutamate, this will lead to prolonged depolarization of the neuronal membrane.
Due to influx of extracellular Ca++, which leads to the opening of voltage-dependent Na+ channels, influx of Na+, and generation of repetitive action potentials. These are due to abnormal excitation from brain. Epilepsy treatment methods are aimed at controlling the disease. All of the epilepsy cases are not alike. Idiopathic (60 -70%), there can be apparent reasons like stress, brain injury, genetic conditions and parasitic infection of brain.It is also observed that instance of epilepsy can occur without any solid provable reason.
