While most seizures occur immediately after the injury or within the first year, it is also possible for epilepsy to surface years later. Epilepsy includes both major or generalized seizures and minor or partial seizures. The person falls unconscious to the ground. His or her body stiffens, then jerks convulsively. The mouth, eyes, legs and arms move.
Urinary incontinence is common.
After several minutes, the jerking movements slow and the seizure ends. The person will likely be drowsy afterwards and may not remember the seizure. The extent of an individual's enduring problems after a brain injury depend on many factors. Prompt and proper diagnosis and treatment can help minimize some consequences of brain injury. However, it is usually difficult to predict the outcome of a traumatic brain injury in the first hours, days, or weeks.
