===Epilepsy===
[[Epileptic seizure]]s are thought to relate to abnormal electrical activity.{{sfn|Davidson's|2010|pp=1172-9}} Seizure activity can manifest as [[absence seizure|absence of consciousness]], [[focal seizure|focal]] effects such as limb movement or impediments of speech, or be [[generalised seizure|generalized]] in nature.{{sfn|Davidson's|2010|pp=1172-9}} [[Status epilepticus]] refers to a seizure or series of seizures that have not terminated within five minutes.<ref name="foundation">{{cite web |title=Status Epilepticus |url=https://www.epilepsy.com/learn/challenges-epilepsy/seizure-emergencies/status-epilepticus |website=Epilepsy Foundation}}</ref> Seizures have a large number of causes, however many seizures occur without a definitive cause being found. In a person with [[epilepsy]], risk factors for further seizures may include sleeplessness, drug and alcohol intake, and stress. Seizures may be assessed using [[blood test]]s, [[EEG]] and various [[medical imaging]] techniques based on the [[medical history]] and [[medical examination]] findings.{{sfn|Davidson's|2010|pp=1172-9}} In addition to treating an underlying cause and reducing exposure to risk factors, [[anticonvulsant]] medications can play a role in preventing further seizures.{{sfn|Davidson's|2010|pp=1172-9}}
