Study Arms (1)

Adults with epilepsy

Adults over 18 years of age, with an unprovoked seizure in the last year or epilepsy, resident in VGR at the time of inclusion. Languages available: Swedish, English, Arabic. Based on the clinical information, patients can be categorized into relevant groups; single seizure, seizure-free with epilepsy, and drug-resistant epilepsy. Subgroups may also be selected based on age, sex, epilepsy sub-diagnosis, cause of epilepsy, use of a particular antiepileptic drug, or experience of a particular side effect.

Other: Seizure statusDiagnostic Test: TestsOther: EpilepsyOther: Demographics and psychosocialOther: Health care

Interventions

We will collect information on first seizure ever, last seizure ever, number of seizure in last two months.

Adults with epilepsy
TestsDIAGNOSTIC_TEST

We will collect results from imaging, electroencephalogram, and laboratory tests.

Adults with epilepsy

We will collect information on risk factors of epilepsy, cause of epilepsy, epilepsy type/syndrome, medications tried, if the epilepsy is drug resistent, side effects of antiepileptic drugs.

Adults with epilepsy

We will collect information on age, sex, date of death if applicable, marital status, education level, income type, driving status, employment, benefits, sick leave, number of household members.

Adults with epilepsy

We will collect information on received health care; visit dates, caregiver, dispensation dates of antiepileptic drugs
