Official title
Prospective Regional Epilepsy Database and Biobank for Individualized Clinical Treatment
Overview
PREDICT is an observational study following adults with an unprovoked seizure or epilepsy in the health care region of western Sweden. The objective is to identify biomarkers and/or genetic predisposition of relevance for diagnosis and/or treatment of epilepsy and study the long-term prognosis and consequences of epilepsy.
Detailed description
Adults over 18 years of age, with an unprovoked seizure in the last year or epilepsy, resident in the health care region of western Sweden (VGR) at the time of inclusion.
Baseline data and outcome variables are collected from several patient registries: the electronic medical records system in the health care region VGR and Swedish National Registers of healthcare, income, and employment managed by The National Board of Health and Welfare or Statistics Sweden, both of which are government agencies.
Interventions
- Other Seizure status
We will collect information on first seizure ever, last seizure ever, number of seizure in last two months. - Diagnostic test Tests
We will collect results from imaging, electroencephalogram, and laboratory tests. - Other 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. - Other Demographics and psychosocial
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. - Other Health care
We will collect information on received health care; visit dates, caregiver, dispensation dates of antiepileptic drugs
