Benign neonatal seizures are not classified as epilepsy and the seizures usually resolve after 1–4 months. [30] A benign familial neonatal seizure onsets as early as 3 days of birth and may involve one or both sides of the brain. Recurrent seizure episodes are observed to occur in neonates.
Post-traumatic seizures (PTS) are seizures that result from traumatic brain injury (TBI), brain damage caused by physical trauma.PTS may be a risk factor for post-traumatic epilepsy (PTE), but a person having a seizure or seizures due to traumatic brain injury does not necessarily have PTE, which is a form of epilepsy, a chronic condition in which seizures occur repeatedly.
Seizures that occur after head injury are not necessarily due to epilepsy or even to the head trauma. [11] Like anyone else, TBI survivors may have seizures due to factors including imbalances of fluid or electrolytes , epilepsy from other causes, hypoxia (insufficient oxygen), and ischemia (insufficient blood flow to the brain).

After a brain injury occurs, there is frequently a "silent" or "latent period" lasting months or years in which seizures do not occur; [6] Canadian neurosurgeon Wilder Penfield called this time between injury and seizure "a silent period of strange ripening". [7]
Because epileptic seizures typically include convulsions, the term convulsion is often used as a synonym for seizure. [1] However, not all epileptic seizures result in convulsions, and not all convulsions are caused by epileptic seizures. [1] [2] Non-epileptic convulsions have no relation with epilepsy, and are caused by non-epileptic seizures. [1]
Infants who do give indications of stroke in the womb or shortly after birth commonly experience seizures. [3] When an infant has a seizure, they experience jerking in the face, legs, or arms, alongside delayed breathing. [4] Seizures are mostly caused by hypoxic-ischemic encephalopathy (HIE) or perinatal asphyxia. [34]
Hypoxia refers to deficiency of oxygen, Ischemia refers to restriction in blood flow to the brain. The result is “encephalopathy” which refers to damaged brain cells. Encephalopathy is a nonspecific response of the brain to injury which may occur via multiple methods, but is commonly caused by birth asphyxia, leading to cerebral hypoxia. [2 ...
