Temporal lobe epilepsy; (Wikipedia)
Simple Partial Seizures (SPS) involve small areas of the temporal lobe such as the amygdala or the hippocampus. The term "simple" means that consciousness is not altered. In temporal lobe epilepsy SPS usually only cause sensations. These sensations may be mnestic such as déjà vu (a feeling of familiarity), jamais vu (a feeling of unfamiliarity), a specific single or set of memories, or amnesia. The sensations may be auditory such as a sound or tune, gustatory such as a taste, or olfactory such as a smell that is not physically present. Sensations can also be visual, involve feelings on the skin or in the internal organs. The latter feelings may seem to move over the body. Psychic sensations can occur such as an out-of-body feeling. Dysphoric or euphoric feelings, fear, anger, and other sensations can also occur during SPS. Often, it is hard for persons with SPS of TLE to describe the feeling. SPS are often called "auras" by lay persons who mistake them for a warning sign of a subsequent seizure. In fact, they are indeed seizures. Persons experiencing only SPS may not recognize what they are or seek medical advice about them.
