Editing Seizure (section)

==Epidemiology==
Seizures are relatively common neurological events, with an estimated lifetime risk of experiencing at least one seizure approaching 8-10% within the general population. However, not all seizures are indicative of epilepsy; numerous episodes are provoked by transient factors such as infections, metabolic abnormalities, or trauma. In adults, the risk of seizure recurrence within the five years following a new-onset seizure is 35%; the risk rises to 75% in persons who have had a second seizure.<ref name="Gavvala20162">{{cite journal |vauthors=Gavvala JR, Schuele SU |date=December 2016 |title=New-Onset Seizure in Adults and Adolescents: A Review |journal=JAMA |volume=316 |issue=24 |pages=2657–2668 |doi=10.1001/jama.2016.18625 |pmid=28027373}}</ref> In children, the risk of seizure recurrence within the five years following a single unprovoked seizure is about 50%; the risk rises to about 80% after two unprovoked seizures.<ref>{{cite journal | vauthors = Camfield P, Camfield C | title = Incidence, prevalence and aetiology of seizures and epilepsy in children | journal = Epileptic Disorders | volume = 17 | issue = 2 | pages = 117–123 | date = June 2015 | pmid = 25895502 | doi = 10.1684/epd.2015.0736 | s2cid = 20719640 | doi-access = free }}</ref> In the United States in 2011, seizures resulted in an estimated 1.6 million emergency department visits; approximately 400,000 of these visits were for new-onset seizures.<ref name="Gavvala20162" />

Global variations exist, with higher rates of seizures and epilepsy reported in regions with elevated prevalence of risk factors such as central nervous system infections, traumatic brain injury, and limited access to perinatal care. Seizures contribute significantly to the global burden of neurological disease, affecting individuals' quality of life, social participation, and access to education and employment.
