04 What is an aura?
Before the onset of a seizure some people experience a sensation or
warning called an "aura". The aura may occur far enough in advance to
give the person time to avoid possible injury. The type of aura
experienced varies from person to person. Some people feel a change in
body temperature, others experience a feeling of tension or anxiety. In
some cases, the epileptic aura will be apparent to the person as a
musical sound, a strange taste, or even a particular curious odour. If
the person is able to give the physician a good description of this
aura, it may provide a clue to the part of the brain where the initial
discharges originate. An aura could occur without being followed by a
seizure, and in some cases can by itself be called a type of simple
partial seizure.
