A
brief temporary alteration in movement,
sensation or
autonomic nerve function caused by
emergency electrical activity in a
localised area of the brain. Focal
seizures (i.e. Partial or Jacksonian seizures) generally
reason no
change in
awareness or alertness. An example of a
focal (partial)
seizure would be rhythmic
muscle contractions in one
area of the body:
lip smacking,
mouth movements, drooling,
head turning,
eye movements or
seemingly purposeful movements (for example
picking at clothes). Another presentations may be strictly
sensory with
emergency numbness,
tingling or a crawling
sensation to the skin. More unusual symptoms include changes in speech, thought, personality, mood,
sensation of
deja vu or hallucinations.
