PARTIAL (FOCAL) SEIZURE PARTIAL SEIZURE begins focally and results from abnormal electrical discharges in a circumscribed portion of the brain. The partial seizure may be clinically manifested by a comparably restricted disturbance of cognition, behavior, sensation or movement (Marrlow and Redding, 2009).
1. Simple Partial Seizures: Simple partial seizures are defined as abnormal neuronal discharges occurring in only one hemisphere of the brain (partial) in which consciousness is preserved (simple). These episodes usually last a few seconds but can last longer, and are often referred to the individual as an “aura” that portends a second seizure type. Depending on the part of the brain afflicted by the excessive firing, the symptoms of the aura are varied and may include paresthesias, hallucinations, dysphagia, sweating, flushing, or motor disturbances, such as jerking (Clore, 2010).

2. Complex Partial Seizures (Temporal Lobe): A complex partial seizure (CPS) occurs when epileptic activity spreads to both temporal lobes in the brain. A complex partial seizure often occurs after a simple partial seizure. In some children, they lead to tonic-clonic …show more content…

Partial seizures with secondary generalization: Spreading of the epileptiform discharge during CPS can result in secondary generalization with a tonic-clonic convulsion. During the spread of the ictal discharge throughout the hemisphere, contra lateral versive turning of the head, dystonic posturing, and tonic-clonic movements of the extremities and face, including eye blinking, may be noted (Kliegman et al, 2011 and Devinsky et al., 2014).

II- GENERALIZED SEIZURES A generalized seizure is one in which the neuronal discharge occurs in both hemispheres of the brain and may involve a depressed level of consciousness (Blumstein & Friedman, 2007 and American Epilepsy society, 2015).There are two main categories of generalized seizures: convulsive and non-convulsive (Clore, 2010).
