Most people who suffer from traumatic brain injuries do not suffer from seizures. But it does happen occasionally and so its worth discussing how a seizure happens and the different types of seizures that can result from a traumatic brain injury. After head trauma, a seizure is most likely to happen within the following few hours. Afterwards, if a seizure is going to occur, doctors say it will most likely happen 10 months or so after a head injury.
Different Types of Seizures
There are two broad types of seizures:
Partial Seizures: More likely to occur in adults. In a partial seizure the sufferer will experience abnormal activity in a specific area of the brain.
Generalized Seizures: More serious than simple seizures; generalized seizures show abnormal brain activity in both hemispheres.
Some specific kinds of seizures are:
Myclonic Seizures: most often associated with brain tumors and head injuries. When a myclonic seizure is produced, the sufferer will remain conscious (like petite mal seizure, discussed below) and may convulse (like grand mal seizures, discussed below). Myclonic seizures are more likely to occue when the sufferer is sleep deprived.
Atonic Seizures: the sufferer loses consciousness as his/her muscles relax and go limp. Atonic seizures are often overlooked as a fainting spell.
Petite Mal Seizures/Absense Seizures: often looks like the person is staring out into space, daydreaming or simply unaware of his/her surroundings (sufferer remains conscious during a petite mal seizure). Petite Mal Seizures are often seen in children and teenagers. Petite Mal Seizures are also sometimes referred to as absense seizures.
Grand Mal Seizures/Tonic-Clonic Seizures: when you think of a seizure, this the one that probably enters your mind. The sufferer of a Grand Mal Seizure will typically exhibit violent muscle convulsions, lose control of several bodily function as well as lose consciousness. Grand mail seizures are sometimes referred to as tonic clonic seizures.
