Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: For patients: * Men and women aged between 18 and 40 * Person affiliated to social security or beneficiary of such a regime * idiopathic generalized epilepsy treated with lamotrigine, an association of lamotrigine, topiramate, levetiracetam, lamotrigine or levetiracetam alone (group patients) for at least 14 days without changing doses The idiopathic generalized epilepsy is defined by generalized seizures: generalized tonic-clonic seizures, absences or myoclonic seizures, excluding any other type of seizure, and electroencephalographic appearance following: presence of interictal EEG discharge generalized to type of spikes, spike-wave or wave polyspikes generalized, sporadic or rhythmic\> or = 3 Hz background activity is normal. For healthy volunteers: * Men and women aged between 18 and 40 * Person affiliated to social security or beneficiary of such a regime Exclusion Criteria: * Topic wrongly included * Deflecting protocol that can skew the primary endpoint * Primary endpoint missing * If the investigator considers the health of the subject is incompatible with the continuation of the study. Criteria for non-inclusion * For patients: * The presence of interictal focal discharges on EEG previous * The emergence of partial seizures * Restless Leg Syndrome * All non-antiepileptic treatment may affect levels of dopamine * Current use of illicit drugs. * A person deprived of liberty by judicial or administrative person being a measure of legal protection. * Pregnant, parturient, lactating mother. * For women, lack of effective contraception * For healthy volunteers: * Any medical treatment associated * Current use of illicit drugs * Pregnant, parturient, lactating mother * For women, lack of effective contraception * A person deprived of liberty by judicial or administrative person being a measure of legal protection.
