Please obtain accurate information and advice from your GP, epilepsy specialist doctor or nurse before making any changes to your epilepsy medicines. This is so important as untreated epilepsy can lead to increased risk of serious harm from uncontrolled seizures. Information on why women with epilepsy are advised to plan pregnancy, on this page.
It is advisable that you receive support during the child-bearing years. It is important not to stop anti-epileptic drugs without seeking accurate advice from a doctor or epilepsy specialist due to risks of untreated epilepsy. If your diagnosis has not been reassessed in adult years, please discuss this with your GP before considering pregnancy. Join the big conversation Facebook support group women with epilepsy
It is important that you have the opportunity of having a medication review before pregnancy. However the type of epilepsy can limit choice of treatment. Some epilepsies, particularly generalised (genetic) may only respond to valproate. All women should receive accurate information about the possible effects of their antiepileptic drugs on a developing baby before they become pregnant.
Many women with epilepsy are understandably anxious about pregnancy. To help with your decision making, you should be provided with accurate evidence based advice about fertility, contraception, pregnancy, breast feeding and safe parenting. Feel reassured that the majority of women with epilepsy have normal pregnancies and birth healthy babies.
Epilepsy is a serious neurological disease in which unprovoked, unpredictable seizures occur as a result of sudden bursts of excessive electrical activity in the brain.
The diagnosis should either be made by a specialist paediatrician in childhood or a medical practitioner also with training and expertise in epilepsy, in adulthood, following at least two unprovoked (or reflex) seizures occur more than 24 hours apart; or following one unprovoked seizure and a probability of further seizures similar to the general risk of recurrence (at least 60%) after two unprovoked seizures occurring over the next two years; or a diagnosis of an epilepsy syndrome .
Epilepsy is usually diagnosed before age 20 and over age 65; but can occur at any time. The symptoms are individual to the person they are affecting and dependant on where in the brain they start, and where the abnormal electrical activity spreads within the brain. If a seizure starts in one part of the brain, it is called focal and if it involves most of the brain at the outset of the seizure, it is called generalised. Sometimes people can have a combination of seizure types or their epilepsy cannot be classified. Further information about what epilepsy is, how it is diagnosed and treated and information to help you take control of your condition, can be obtained from these excellent support groups: Epilepsy Action, Epilepsy Society, Epilepsy Research, SUDEP Action, Epilepsy Scotland

No, seizures can be caused by a number of conditions including: syncope (fainting) due to a drop in blood pressure, lack of oxygen (anoxia) or a cardiac condition such as long QT wave. Syncope and non epileptic attack disorder characterised by disassociative seizures (also called non-epileptic seizures) are the leading causes of epilepsy misdiagnosis. If you have been diagnosed with a psychological cause for your seizures, do access excellent information and support from NEAD. Please note that some people with known epilepsy can also experience non-epileptic seizures. Other causes of misdiagnosis include migraine, sleep disorders and paroxysmal movement disorders 
Metabolic disorders such as diabetes related to very low or high blood sugar; low sodium (salt); hypercalcaemia (high blood calcium levels) and thyroid dysfunction can provoke seizures. Many prescribed and unprescribed drugs, alcohol, some homeopathic drugs and recreational drugs can also lead to seizures.
Febrile convulsions (seizures usually related to raised temperature in the very young), stroke, head injury/trauma, meningitis, encephalitis, eclampsia, (a rare but serious cause of seizures in pregnancy), brain tumour, cerebral malaria, electric shock  and toxic shock syndrome are examples of conditions that can present with convulsive or non-convulsive seizures. This does not necessarily mean the person will go onto develop epilepsy however; having a history of any of these causal conditions can significantly increase the risk of developing epilepsy.
Yes; about 2,500 births occur annually to women with epilepsy in the UK.
The majority of women treated with antiepileptic drugs (AEDs) have good seizure control. However, it is important the GP refers you to a specialist if your epilepsy diagnosis and treatment has not been reassessed recently by an expert medical practitioner in epilepsy; if you are taking sodium valproate; if you have uncontrolled seizures despite taking medication; if you are taking more than one AED; if you have nocturnal seizures; if you have a history of prolonged seizures or if you have been more than two years seizure free whilst taking AEDs. If you do not meet any of these criteria, you can still ask for an expert opinion. A reassessment will provide advice to enable you to make a shared informed decision about your future treatment and management in preparation for pregnancy and parenting.
The majority of women have a healthy baby following a normal pregnancy and labour but it is important to reduce the risk of harm through careful pregnancy planning. AEDs can be associated with an increased risk of birth defects. The risk of these problems is often low but will depend on the type and number of AEDs prescribed; the dosage, family history of congenital malformations and other conditions such as thyroid disease and diabetes. Alcohol [4.5] and smoking  are also linked to an increased risk of congenital malformations and other complications in pregnancy. The risk of congenital malformations and a fetal anticonvulsant syndrome which can include developmental problems and intellectual disabilites, is particularly increased in women prescribed sodium valproate in pregnancy. Please click on MHRA valproate guide for patients for further information if you are taking sodium valproate. Please note the brand names for sodium valproate and valproic acid are: Epilim, Epilim Chrono, Epilim Chronosphere, Episenta, Epival, Depakote and Convulex.
Do not suddenly stop AEDs without seeking urgent medical advice from your GP/epilepsy specialist. Suddenly stopping AEDs can be associated with uncontrolled seizures resulting in serious harm and in rare cases, sudden unexpected death.
Some AEDs induce enzymes in the liver which reduce the effectiveness or oral contraceptives, the implant, emergency contraception, hormonal patches and the reliability of natural methods of contraception. In addition, the combined oral contraceptive can reduce the effectiveness of lamotrigine. Therefore, it is strongly recommended that you seek advice from your GP or contraception and sexual health clinic in advance of sexual activity to reduce the risk of unplanned pregnancy. Click on: Care of baby & you for more detailed contraception advice and Epilepsy Action contraception advice. Advice for your professional from: Drug interactions with hormonal contraception, Click: CEU Clinical Guidance
It is currently recommended in national guidelines in the UK that if you take antiepileptic drugs that your GP prescribes folic acid 5 milligrams once daily for three months before you stop contraception or if there is risk of unplanned pregnancy. The advice recommends that you continue this until you are 12 weeks pregnant as it is thought to reduce the risk of neural tube defects, including spinal bifida . This dosage of folic acid cannot be bought over the counter; it has to be prescribed by your GP who will ensure this is a safe drug and dosage for you to take with your antiepileptic drug regime. There is data that folic acid taken in pregnancy may reduce the risk of a child having autism in women taking AEDs however, further research is required in this area . Further research is also required into what is the safest dose of folic acid to recommend women with epilepsy take during pregnancy and whether the higher prescribed dose is safe and offers any extra protection [9,10].
