A seizure originating in the temporal lobe of the brain may be preceded by an aura or warning symptom, such as:

Hallucinations (including sights, smells, tastes)
Vivid deja vu (a sense of familiarity) or recalled memories or emotions
A sudden, intense emotion not related to anything happening at the time

Causes of Epilepsy
There are around 180,000 new cases of epilepsy each year. About 30% occur in children. Children and elderly adults are the ones most often affected.
There is a clear cause for epilepsy in only a minority of the cases. Typically, the known causes of seizure involve some injury to the brain. Some of the main causes of epilepsy include:
Low oxygen during birth
Head injuries that occur during birth or from accidents during youth or adulthood
Abnormal levels of substances such as sodium or blood sugar
In up to 70% of all case of epilepsy in adults and children, no cause can be discovered.
