Observable manifestations are also used when describing seizure types; these may be motor or non-motor. Motor relates to physical movement or motion, and seizures involving motor activity may include either an increase or decrease in muscle tone, leading to muscle twitches, jerks or contractions. Non-motor onset seizures don’t involve muscle action but may include behavioural, emotional and/or sensory activity or actions.
Some people experience non-epileptic seizures, which don’t fit into these three categories.
