Does Epilepsy strike at any particular age? Is it hereditary?

Epilepsy primarily affects children and young adults, although anyone can get epilepsy at anytime. 20% of cases develop before the age of five, and 50% develop before the age of 25. However, epilepsy is also increasingly associated with the elderly, and there are as many cases in those 60 years of age and older as in children 10 years of age and under.
Heredity usually is not a direct factor in epilepsy. But some kinds of brain wave patterns associated with seizures do tend to run in families.

Most people who develop seizures during their earlier years tend to experience a reduction in the intensity and frequency of their seizures as they grow older. In many cases the Epilepsy will disappear completely.
