Epilepsy — a chronic neurological disorder characterised by recurrent seizures — affects approximately 50 million people worldwide, making it one of the world's most common neurological diseases, yet 70% of people with epilepsy could live seizure-free with appropriate treatment (WHO). The treatment gap is staggering: 75% of people with epilepsy in LMICs receive no treatment at all — largely because of the cost, availability and cultural stigma associated with the disease. The WHO Intersectoral Global Action Plan on Epilepsy and Other Neurological Disorders 2022-2031 targets closing this gap.

Key messages

50 million affected
Epilepsy — a chronic neurological disorder characterised by recurrent unprovoked seizures — affects approximately 50 million people worldwide, making it one of the world's most common neurological diseases (WHO).
70% could be seizure-free
70% of people with epilepsy could live seizure-free with appropriate antiseizure medication (ASM). Yet in LMICs, 75% of people with epilepsy receive no treatment — the largest treatment gap of any major neurological condition.
IGAP 2022-2031
The WHO Intersectoral Global Action Plan on Epilepsy and Other Neurological Disorders (IGAP) 2022-2031 targets closing the epilepsy treatment gap and reducing the burden of epilepsy through primary health care integration.
Stigma is a major barrier
In many cultures, epilepsy is associated with supernatural beliefs, witchcraft or contagion — causing severe stigma, social exclusion and discrimination in education and employment. Stigma is a leading barrier to treatment-seeking.
Preventable causes
Up to 25% of epilepsy is preventable: through prevention of traumatic brain injury (helmets, road safety); prevention of stroke (blood pressure control); prevention of perinatal brain injury (skilled birth attendance); and control of neurocysticercosis (Taenia solium) — the leading preventable cause of epilepsy in endemic areas.
SUDEP risk
Sudden Unexpected Death in Epilepsy (SUDEP) — unexplained death in an otherwise healthy person with epilepsy — is a significant mortality risk, occurring in approximately 1 in 1,000 people with epilepsy per year. Seizure control through medication is the primary protective measure.

Glossary of key terms

Epilepsy
WHO/ILAE
A neurological disorder defined by: at least two unprovoked seizures >24 hours apart; one unprovoked seizure with ≥60% recurrence probability; or an epilepsy syndrome. Characterised by recurrent seizures from abnormal electrical brain activity.
Seizure
ILAE
A transient occurrence of signs and/or symptoms caused by abnormally excessive or synchronous neuronal activity in the brain. Types: focal (arising in one brain region) or generalised (involving both hemispheres from onset). Manifestations: motor, sensory, autonomic or psychic.
Antiseizure medication (ASM)
WHO EML
Medicines that reduce seizure frequency and severity. First-line ASMs (phenobarbital, carbamazepine, valproate, lamotrigine) are on the WHO Essential Medicines List. 70% of people with epilepsy can become seizure-free with appropriate ASM — but access in LMICs is severely limited.
Treatment gap
WHO/ILAE
The proportion of people with active epilepsy who do not receive appropriate treatment. Globally approximately 50%; in LMICs up to 75-90%. Caused by drug unavailability, cost, lack of diagnosis, stigma, cultural barriers and insufficient neurological workforce.
Neurocysticercosis
WHO
Brain infection by Taenia solium larvae (pork tapeworm) — the leading preventable cause of epilepsy in endemic regions (Latin America, Africa, Asia). Prevented by improved sanitation, pig management and inspection of pork. Treated with albendazole/praziquantel.
SUDEP
Epilepsy Foundation
Sudden Unexpected Death in Epilepsy — unexplained death in an otherwise healthy person with epilepsy. Affects ~1 in 1,000 people with epilepsy per year; highest risk with uncontrolled seizures. Seizure control through medication is the primary preventive measure.
