Overview
- Global estimates cite about 50 million people living with epilepsy and roughly 5 million new diagnoses each year.
- The Spanish Neurology Society reports more than 500,000 people affected in Spain and stresses that at least 30% of cases are preventable by reducing head trauma, infections and vascular risks.
- Roughly 80% of cases occur in low- and middle-income countries, where three in four people do not receive adequate treatment.
- A Mexican neurologist reports a local prevalence around 2–5% and links higher rates to parasitic infections, perinatal injury and poor sleep, with triggers including sleep deprivation, anxiety, alcohol and caffeine.
- WHO-linked figures indicate about 70% can achieve seizure control with accurate diagnosis and appropriate therapy, though roughly 30% may not respond to a first medication and may need specialized care or surgery.
