Epilepsy Statistics (link)
From this mixture of sources, leading experts in the field have arrived
at the following estimates of the incidence and prevalence of seizures
and epilepsy in the United States:
Incidence -- Seizures:
-300,000 people have a first convulsion each year.
-120,000 of them are under the age of 18.
-Between 75,000 and 100,000 of them are children under the age of 5 who have experienced a febrile (fever-caused) seizure.
Incidence -- Epilepsy:
-200,000 new cases of epilepsy are diagnosed each year.
-Incidence is highest under the age of 2 and over 65.
-45,000 children under the age of 15 develop epilepsy each year.
-Males are slightly more likely to develop epilepsy than females.
-Incidence is greater in African American and socially disadvantaged populations.
-Trend shows decreased incidence in children; increased incidence in the elderly.
-In 70 percent of new cases, no cause is apparent.
-50 percent of people with new cases of epilepsy will have generalized onset seizures.
-Generalized
seizures are more common in children under the age of 10; afterwards
more than half of all new cases of epilepsy will have partial seizures.
Prevalence -- Epilepsy:
-Prevalence of active epilepsy
(history of the disorder plus a seizure or use of antiepileptic
medicine within the past 5 years) is estimated as approximately 2.7
million in the United States.
-Prevalence tends to increase with age.
-326,000 school children through age 14 have epilepsy.
-570,000 persons over the age of 65 have epilepsy.
-Higher among racial minorities than among Caucasians.
Cumulative incidence (risk of developing epilepsy):
-By 20 years of age, one percent of the population can be expected to have developed epilepsy.
-By
75 years of age, three percent of the population can be expected to
have been diagnosed with epilepsy, and ten percent will have
experienced some type of seizure.
Epilepsy risk in special populations:
The
basic, underlying risk of developing epilepsy is about one percent.
Individuals in certain populations are at higher risk. For example, it
is estimated that epilepsy can be expected to develop in:
-10 percent of children with mental retardation
-10 percent of children with cerebral palsy
-50 percent of children with both disabilities
-10 percent of Alzheimer patients
-22 percent of stroke patients
-8.7 percent of children of mothers with epilepsy
-2.4 percent of children of fathers with epilepsy
-33 percent of people who have had a single, unprovoked seizure
Remission
-70 percent of people with epilepsy can be expected to enter remission, defined as 5 or more years seizure free on medication.
-35 percent of people with mental retardation, cerebral palsy, or other neurological condition will enter remission.
-75 percent of people who are seizure free on medication for 2 to 5 years can be successfully withdrawn from medication.
-10 percent of new patients fail to gain control of seizures despite optimal medical management.
