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.
Neurology. Post-traumatic epilepsy (PTE) is a form of acquired epilepsy that results from brain damage caused by physical trauma to the brain (traumatic brain injury, abbreviated TBI). [1] A person with PTE experiences repeated post-traumatic seizures (PTS, seizures that result from TBI) more than a week after the initial injury. [2]
A brain injury can cause seizure(s) because of the unusual amount of energy that is discharged across of the brain when the injury occurs and thereafter. A disruption of the supply of oxygen may cause damage to the temporal lobe of the brain. [35] The risk of seizure(s) from a closed head injury is about 15%. [36]
Seizures that occur after brain injury may be due to the brain adapting to injury (neuroplasticity). [41] This process is known as epileptogenesis. [42] There is loss of inhibitory neurons because they die due to the injury. [42] [41] The brain may also adapt and make new neuron connections that may be hyper-excitatory. [42] [41]
A traumatic brain injury (TBI), also known as an intracranial injury, is an injury to the brain caused by an external force. TBI can be classified based on severity ranging from mild traumatic brain injury (mTBI/concussion) to severe traumatic brain injury. [5] TBI can also be characterized based on mechanism (closed or penetrating head injury ...
The relative risk of post-traumatic seizures increases with the severity of traumatic brain injury. [20] Pain, especially headache, is a common complication following a TBI. [1] Being unconscious and lying still for long periods can cause blood clots to form (deep venous thrombosis), which can cause pulmonary embolism. [21]
