Pregnancy in women with epilepsy is associated with an increased risk of fetal malformation.

    As with cancer, there are variations in the routine treatment of epilepsy in pregnancy. It would be considered unethical to carry out a clinical trial of treatment, but because many pregnancies occur in women already taking a variety of anti-epileptic drugs (for many of which no reliable data on teratogenicity in humans exists) valuable information could become available if only it was collated. It was on this premise that the UK Epilepsy and Pregnancy Register was established.

Few patients have refused or withdrawn consent, and indeed most are delighted that some research is being carried out on this subject.
