Morbidity and mortality of childhood- and adolescent-onset epilepsy: A controlled national study

Area of Science:

• Neurology
• Public Health
• Epidemiology

Background:

• Epilepsy is a chronic neurological disorder associated with substantial morbidity and mortality.
• Understanding the long-term health consequences is crucial for patient management and public health strategies.

Purpose of the Study:

• To evaluate the 30-year morbidities and mortality in a national cohort of patients following their first epilepsy diagnosis.
• To assess the impact of epilepsy on overall health across various disease domains over three decades.

Main Methods:

• Utilized the Danish National Patient Registry (NPR) to identify patients diagnosed with epilepsy between 1998-2002.
• Compared epilepsy patients (aged 0-5 and 6-20 at diagnosis) with matched control groups from the Danish Civil Registration System.
• Grouped and analyzed all recorded morbidities within 30 years post-diagnosis into major WHO disease classes.

Main Results:

• Patients with epilepsy exhibited significantly higher rates of comorbidities across nearly all health domains compared to controls.
• Elevated mortality rates were observed: hazard ratios were 14.46 for early-onset (0-5 years) and 5.58 for later-onset (6-20 years) epilepsy.
• The increased risk of comorbidities and mortality was particularly pronounced in individuals diagnosed at a younger age.

Conclusions:

• Epilepsy is linked to significant long-term comorbidities and increased mortality across all healthcare domains.
• Early-onset epilepsy presents a substantially higher risk for adverse health outcomes and mortality over a 30-year period.
• These findings underscore the need for comprehensive, long-term care and monitoring for individuals with epilepsy, especially those diagnosed in childhood.
