Re: Epilepsy in pregnancy.

The article by Tomson and Hiilesmaa (1) provides a nice summary outlining the problems and management of women in epilepsy. The authors probably overlooked the recommendation by the American Academy of Neurology's guidelines on women with epilepsy suggesting supplementing patients on enzyme inducing antiepileptic drugs with vitamin K (2).

Re: Status in pregnancy

Tomson & Hiilesmaa suggest that "refractory status epilepticus in the third trimester of pregnancy could be an indication for a caesarean". This may be true, but one potential pitfall which needs to be considered in this situation is pseudostatus epilepticus in pregnancy. Such a case in which emergency caesarean was considered prior to correct diagnosis has been reported.1 Although published cases are few,2 and the true incidence is unknown, it should be borne in mind that pseudostatus epilepticus occurs predominantly in women of childbearing age, and is commoner than true status epilepticus in specialised neurological practice.

Presentation during pregnancy may put the fetus at “double jeopardy”: on the one hand from cyanosis associated with the seizures which may be associated with fetal hypoxia, necessitating respiratory support and the attendant complications of sedation; and on the other hand, from the understandable anxiety that seizures may reflect neurological complications of eclampsia, requiring prompt operative delivery of the fetus with the attendant risks of prematurity. Hence, this is a condition which both obstetricians and neurologists need to be aware of.
