Table 4.

Frequency of different health states (indicating different severity levels) of epilepsy in an onchocerciasis hyperendemic area, associated disability weights for each health state (GBD), and calculation of the weighted mean disability weight across health states (weighted for the proportion of cases in each health state, based on Prischich et al. 2008 [44])

Health state	Proportion of epilepsy patients with health state	Disability weight
Severe epilepsy	37%	0.552
Less severe epilepsy	47%	0.263
Seizure-free, treated epilepsy	16%	0.049
Weighted mean disability weight, weighted by the proportion of cases in each health state		0.336
