The kind of seizure an individual experiences with a metabolic dysfunction will depend upon the kind of dysfunction and the severity of the dysfunction. Seizures attributable to metabolic problems could be handled with treatment. In some circumstances, surgical procedure could also be essential to appropriate the underlying dysfunction.
Genetic elements
Genetic elements play a job within the improvement of epilepsy and different seizure problems. Research have proven that individuals with a household historical past of epilepsy usually tend to develop the dysfunction than individuals with no household historical past of epilepsy. Nevertheless, most individuals with epilepsy do not need a household historical past of the dysfunction.
- Inherited epilepsy syndromes: Inherited epilepsy syndromes are uncommon genetic problems that trigger epilepsy. These syndromes are often attributable to mutations in a single gene. Inherited epilepsy syndromes could be handed down from mother and father to kids.
- Genetic susceptibility to epilepsy: Some individuals have a genetic susceptibility to epilepsy, which implies that they’re extra prone to develop the dysfunction if they’re uncovered to sure environmental triggers. Environmental triggers for epilepsy embody head damage, an infection, and stress.
