Carpay et al developed the Seizure Severity (SS) scale for evaluating impact of seizures on a child. This is completed by the child's parent. The authors are from the Juliana Children's Hospital in Den Haag (The Hague) and other children's hospitals in The Netherlands.



(1) frequency of impaired consciousness

(2) duration of impaired consciousness

(3) overall seizure severity

(4) frequency of jerks or cramps

(5) duration of jerks or cramps

(6) noticeability of altered behavior during a seizure

(7) frequency of confusion during or after attack

(8) frequency of urinary incontinence during seizure

(9) frequency of tongue or cheek biting

(10) frequency of other injury related to the attack

(11) frequency of postictal sleepiness

(12) frequency of postictal nausea, headache, or muscle pain

(13) time to normal function after an attack


Responses are 1 (normal) to 4 (severe), except for the duration of jerks and cramps which ranges from 0 to 5.


total score =

= SUM(points for all 13 parameters)



• minimum score: 13

• maximum score: 53 (Carpay 1997 page 347 says the maximum score is 54)

• The higher the score the more severe the seizure severity.
