Refractory seizures in a young army cohort

Area of Science:

• Neurology
• Epidemiology
• Public Health

Background:

• Epilepsy incidence and characteristics in young adult males are crucial for public health planning.
• Understanding seizure types and onset is vital for effective management.

Purpose of the Study:

• To determine the cumulative incidence of epilepsy by age 18 in Singaporean males.
• To characterize seizure types, onset, and management in a cohort of young adult males with epilepsy.

Main Methods:

• A retrospective survey of male Singapore citizens born in 1974 undergoing medical screening at age 18.
• Inclusion of 121 diagnosed epileptics from a cohort of 20,542 men, with detailed information from 106 individuals.
• Review of hospital records and patient interviews to gather data on seizure history, types, and neuroimaging findings.

Main Results:

• Cumulative incidence of epilepsy was 5 per 1000 by age 18.
• Generalized seizures (69%) and refractory seizures (13%) were prevalent.
• Seizures typically began before age 7; 9 refractory epileptics had a history of febrile seizures.
• Neuroimaging revealed mesial temporal sclerosis (2), hypothalamic lesion (1), and focal cortical atrophy (2).
• Refractory epilepsy predominantly involved partial seizures (64%).

Conclusions:

• Epilepsy affects young Singaporean males with a notable incidence by age 18.
• Refractory epilepsy, early seizure onset, and partial seizure types are significant clinical features.
• Further research into neuroimaging findings and treatment outcomes, including surgical options, is warranted.
