The term ‘motor’ and ‘non-motor’ are also used when describing seizure types. 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.
