Epilepsy is a clinical syndrome resulting from highly synchronized abnormal discharges of neurons in the brain due to many causes. The pathogenesis of epilepsy is complex and varied, and there is no age limit for its seizures, which can occur at any age.
However, the onset of seizures is closely related to age. For example, infantile spasms tend to start within 1 year of age, childhood catatonic epilepsy peaks at 6-7 years of age, and myoclonic epilepsy often starts around puberty.
The etiology of epilepsy is also different in each age group. 0~2 years old are mostly perinatal injuries, congenital diseases and metabolic disorders; 2~12 years old are mostly idiopathic epilepsy, acute infections, febrile convulsions, etc; 12~18 years old are mostly idiopathic epilepsy, cranio-cerebral trauma, vascular malformations and perinatal injuries, etc. 18~35 years old are mostly cranio-cerebral injuries, cranio-vascular malformations and perinatal injuries.
From 18 to 35 years old are mostly craniocerebral trauma, brain tumor and idiopathic epilepsy, etc.; from 35 to 65 years old are mostly brain tumor, craniocerebral trauma and metabolic disorders, etc.; after 65 years old are mostly brain tumors, cerebrovascular disease, Alzheimer’s disease accompanied by epilepsy.
Therefore, 36 years old may be sudden epilepsy, if there are relevant symptoms, it is recommended to actively seek medical treatment.
