consciousness is usually partially or completely lost
postictal alternation of consciousness is usually brief, may last several minutes

Question 20

Tonic clonic seizure

Answer 20

grand mal

sudden LOC with arrested respirations
clonic phase involves increased muscle tone followed by bilateral rhythmic jerks lasting 2-3 minutes, followed by flaccid coma
urinary or fecal incontinence may occur
postictal state is characterized by deep sleep for up to an hour, headache, disorientation, muscle discomfort, nausea–can last for a minute to hours

Question 21

Atonic seizure

sudden loss of muscle tone

may result in head drop or falling to the ground
