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). [ 11 ]
[3] The epileptic seizure in the vast majority of pediatric epilepsy patients is ephemeral, and symptoms typically subside on their own after the seizure comes to an end, but some children experience what is known as a “seizure cluster," in which the first seizure is followed by a second episode approximately six hours later.
Seizures that occur after brain injury may be due to the brain adapting to injury (neuroplasticity). [40] This process is known as epileptogenesis. [41] There is loss of inhibitory neurons because they die due to the injury. [41] [40] The brain may also adapt and make new neuron connections that may be hyper-excitatory. [41] [40]

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]
