Arms	Assigned Interventions
Active Comparator: 1 Levetiracetam 2000mg/day	Drug: Levetiracetam titrate to 2000mg/day over 22 days, maintain until the end of week 26
Active Comparator: 2 Lamotrigine	Drug: Lamotrigine titrate to 200mg over 10 weeks and maintained until end of week 26

Detailed Description:

Epilepsy is the second most frequent neurologic disease (prevalence 0.5 % - 1 % [Brodie et al. 1997]). About 30 % of epilepsy patients (including many children) suffer from intractable seizures [Kwan & Brodie 2000]. Therefore new drugs and an expansion of permission for drugs with limited approval, respectively, are needed.

Levetiracetam is a new potent antiepileptic drug with nearly ideal pharmacokinetic properties and few side effects [Patsalos 2000], but it is approved in Germany only for add-on therapy for patients > 15 years of age with focal epilepsy.

Due to its few cognitive side effects and its efficacy, Lamotrigine is becoming standard therapy for focal and generalized epilepsy for patients from >11 years of age. Its disadvantage is the possibility of severe allergic reactions which limits the speed of dose increment.

Comparisons: Patients with newly diagnosed epilepsy are treated with either Lamotrigine or Levetiracetam. Rate of seizure-free patients in the first 6 weeks of the trial (main outcome criterion) as well as rate of seizure-free patients during the last 16 weeks and the total 26 weeks of the observation period, time until the first seizure appears, time patients take the study medication, safety and quality of life during treatment are compared.

Eligibility

Ages Eligible for Study:	12 Years and older
Genders Eligible for Study:	Both

Criteria

Inclusion Criteria:

Age ≥ 12 years
Body weight ≥ 30kg (patients 12-15 years of age) and ≥ 40kg (patients over 16 years of age), respectively
Either one epileptic seizure with high risk of relapse (partial seizure semiology, MRI lesion or pathological focal EEG findings) or a newly diagnosed epilepsy (≥ 2 unprovoked seizures) with at least 1 seizure within the past 3 months before begin of trial participance
Treatment with no or a maximum of one anticonvulsant drug at the time of inclusion
Fertile women of ≥ 16 years of age must use at least one of the following contraceptives for at least one month prior to initiation of trial participance: Oral contraceptive, contraceptive diaphragm, intrauterine contraceptive device (coil), tube ligation. For girls between 12 and 15 years of age a written confirmation of sexual abstinence, given by a person having the care and custody of the child, is sufficient.
Informed consent by the proband in written form after being informed about character, relevance and consequences of the clinical trial, and additional informed consent given by a person having the care and custody of the child for patients between 12 and 17 years of age, respectively.

Exclusion Criteria:

Patients who suffer from absence seizures or simple partial seizures without motor signs (aura) only
Patients who had a chronic focal epilepsy or an epileptic state in their medical history
Patients with progressive neurological, degenerative or malignant diseases which are clinically relevant from the investigator's point of view (e.g. cardiovascular or endocrinic diseases)
Patients who have been treated with Levetiracetam or Lamotrigine before
Patients with known manifest renal insufficiency (creatinine clearance < 80 mL/min)
Patients with known hypersensitivity to Levetiracetam, Lamotrigine or another component of the trial drugs

Patients suffering from a psychiatric disease or affective disorders (within the past 6 months), which had to be treated with electric convulsive therapy, tranquilizing agents, monoamine oxidase inhibitors or CNS-active sympathomimetics (e.g. methylphenidate)
Patients who were suffering from alcohol- or drug-addiction within the past 12 months
Pregnant or breast-feeding women
Patients who participated in another clinical trial within the past 30 days
