The prediction of posttraumatic epilepsy. A mathematical approach. 1979

D M Feeney, and A E Walker

Simple mathematical equations can be used to estimate the probability of posttraumatic seizures. Risk factors and time since the injury are taken into consideration in the calculations. The equations are based on a constant probability model derived from published data. When these formulae are applied to data from a variety of published studies, the predicted incidence of posttraumatic epilepsy based on the mathematical model agrees well with the incidence observed in the study groups.

D011336	Probability	The study of chance processes or the relative frequency characterizing a chance process.	Probabilities
D001930	Brain Injuries	Acute and chronic (see also BRAIN INJURIES, CHRONIC) injuries to the brain, including the cerebral hemispheres, CEREBELLUM, and BRAIN STEM. Clinical manifestations depend on the nature of injury. Diffuse trauma to the brain is frequently associated with DIFFUSE AXONAL INJURY or COMA, POST-TRAUMATIC. Localized injuries may be associated with NEUROBEHAVIORAL MANIFESTATIONS; HEMIPARESIS, or other focal neurologic deficits.

D004569	Electroencephalography	Recording of electric currents developed in the brain by means of electrodes applied to the scalp, to the surface of the brain, or placed within the substance of the brain.	EEG,Electroencephalogram,Electroencephalograms
D004834	Epilepsy, Post-Traumatic	Recurrent seizures causally related to CRANIOCEREBRAL TRAUMA. Seizure onset may be immediate but is typically delayed for several days after the injury and may not occur for up to two years. The majority of seizures have a focal onset that correlates clinically with the site of brain injury. Cerebral cortex injuries caused by a penetrating foreign object (CRANIOCEREBRAL TRAUMA, PENETRATING) are more likely than closed head injuries (HEAD INJURIES, CLOSED) to be associated with epilepsy. Concussive convulsions are nonepileptic phenomena that occur immediately after head injury and are characterized by tonic and clonic movements.

D012887	Skull Fractures	Fractures of the skull which may result from penetrating or nonpenetrating head injuries or rarely BONE DISEASES (see also FRACTURES, SPONTANEOUS).
