Harrissons Principles of Internal medicine - 17th ed., Ch.363 Seizures
The most common seizures arising in late infancy and early childhood are febrile seizures, which are seizures associated with fevers but without evidence of CNS infection or other defined causes. The overall prevalence is 3–5% and even higher in some parts of the world, such as Asia.
Childhood marks the age at which many of the well-defined epilepsy syndromes present.
The period of adolescence and early adulthood is one of transition during which the idiopathic or genetically based epilepsy syndromes, including JME and juvenile absence epilepsy, become less common, while epilepsies secondary to acquired CNS lesions begin to predominate. Seizures that begin in patients in this age range may be associated with head trauma, CNS infections (including parasitic infections such as cysticercosis), brain tumors, congenital CNS abnormalities, illicit drug use, or alcohol withdrawal. Head trauma is a common cause of epilepsy in adolescents and adults
The causes of seizures in older adults include cerebrovascular disease, trauma (including subdural hematoma), CNS tumors, and degenerative diseases.
Metabolic disturbances such as electrolyte imbalance, hypo- or hyperglycemia, renal failure, and hepatic failure may cause seizures at any age. Similarly, endocrine disorders, hematologic disorders, vasculitides, and many other systemic diseases may cause seizures over a broad age range. A wide variety of medications and abused substances are known to precipitate seizures as well.

I hope this answers your query. For a more precise answer you need to qualify the question.
