An unusual sensation (aura) may precede a temporal lobe seizure, acting as a warning. Not everyone who has temporal lobe seizures has auras, and not everyone who has auras remembers them. The aura is actually the first part of a focal seizure before consciousness is impaired. Examples of auras include: 
A sudden sense of unprovoked fear or joy
A deja vu experience — a feeling that what's happening has happened before
A sudden or strange odor or taste
A rising sensation in the abdomen, similar to being on a roller coaster
 Sometimes temporal lobe seizures impair your ability to respond to others. This type of temporal lobe seizure usually lasts 30 seconds to two minutes. Characteristic signs and symptoms include: 
Loss of awareness of surroundings
Staring
Lip smacking
Repeated swallowing or chewing
Unusual finger movements, such as picking motions
 After a temporal lobe seizure, you may have: 
A period of confusion and difficulty speaking
Inability to recall what occurred during the seizure
Unawareness of having had a seizure
Extreme sleepiness
 In extreme cases, what starts as a temporal lobe seizure evolves into a generalized tonic-clonic (grand mal) seizure — featuring convulsions and loss of consciousness.
