Although secondary epilepsy is not directly inherited, there are cases in which it can be inherited in an indirect way. For example, there are some secondary epilepsies that result from congenital disorders, commonly callosal hypoplasia and cortical dysplasia. These congenital disorders have a certain degree of heritability, so secondary epilepsy that occurs on top of congenital disorders has a certain probability of being inherited, but it is not directly inherited. The following is an overview of whether secondary epilepsy can be inherited. Cranial injury as well as intracranial infections are a very common cause of secondary epilepsy. These causes appear as acquired factors and are not hereditary. If a person with this disease is treated in a timely manner, and the secondary epilepsy is eventually controlled, he or she will be seizure-free for several years or even decades afterwards, and can consider having children without worrying that the disease will be passed on to the child. There are many causes of secondary epilepsy, which are briefly described below. When analyzing whether a disease is hereditary, it is often the cause of the disease that is analyzed. Genetic predisposition is a very important cause of the disease. However, the causes of secondary epilepsy do not include heredity. The disease can be caused by a tumor inside the skull, by cerebrovascular disease, or by nutritional reasons. For other causes, there is an elderly friend who may have secondary epilepsy triggered by Alzheimer’s disease, and another friend who has secondary epilepsy triggered by tuberous sclerosis disease. Tip: Secondary epilepsy is not a disease that develops through heredity, but rather a disease that is triggered by certain diseases that prompt the formation of epileptic foci, or by certain traumatic injuries that cause epileptic foci. Of course, regardless of whether it is secondary or primary, the disease should be treated and controlled as much as possible without seizures.
