Genetic risk perception and reproductive decision making among people with epilepsy

We investigated estimated offspring risk among people with epilepsy and factors important in the family-planning process. Data were collected for 88 participants using a questionnaire assessing perceived risk of offspring to develop epilepsy, importance of factors in the reproductive decision-making process, decision to have fewer children, and association between risk perception and family planning decisions. Thirty-four percent of participants had fewer children because of their epilepsy. Concerns about the ability to care for a child (p < 0.0001) and passing epilepsy onto a child (p = 0.003) were associated with the decision to have fewer children. The mean estimated risk of offspring to develop epilepsy was 26%, a 4-fold increase over estimated population risks. Genetic counseling may be beneficial for people with epilepsy, given the considerable overestimation of offspring risk.
