Traumatic Brain Injury (TBI) is the leading cause of acquired long term disability among children and young adults. Deficits in attention and memory are common and persist for years after moderate or severe TBI. The similarity between these symptoms and those of children with AD/HD, the efficacy of methylphenidate in the treatment of AD/HD, and the efficacy of methylphenidate in improving recovery of animals with brain injuries, support the need to study methylphenidate effects in children with TBI. This investigation of methylphenidate in children with moderate to severe TBI aims to: (1) Assess the acute effects of 2 different dosages of methylphenidate on attention and reaction time when the medication is administered to children early in recovery; (2) Assess the ability of 8 weeks of methylphenidate to improve the rate of recovery of cognitive, memory, and attentional skills in children with TBI; (3) Identify the frequency of common methylphenidate side effects in children with TBI.
During the first phase of the study which is of 8-days duration subjects will receive placebo on some days and methylphenidate on others. During this phase of the study the effects of the medication on children's performance on a computerized test of attention will be assessed. Individuals who do not have significant methylphenidate side effects during the first phase of the study will then participate in the second phase of the study. During the second phase subjects will receive either methylphenidate or placebo for 8 weeks. Neuropsychological measures of attention, memory, behavioral inhibition, cognitive flexibility, and motor performance will be obtained at baseline and after the 8 week medication trial in order to assess methylphenidate effects on the rate of recovery. Recovery will also be assessed using an interview measure of adaptive behavior and cognitive functioning. A stimulant medication side effect rating scale will be used to monitor for common methylphenidate adverse effects throughout both phases of the study

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.
Brain injuries occurring over a wide area instead of specific focal area.
A form of acquired brain injury which occurs when a sudden trauma causes damage to the brain.
Traumatic injuries to the cranium where the integrity of the skull is not compromised and no bone fragments or other objects penetrate the skull and dura mater. This frequently results in mechanical injury being transmitted to intracranial structures which may produce traumatic brain injuries, hemorrhage, or cranial nerve injury. (From Rowland, Merritt's Textbook of Neurology, 9th ed, p417)
Traumatic injuries involving the cranium and intracranial structures (i.e., BRAIN; CRANIAL NERVES; MENINGES; and other structures). Injuries may be classified by whether or not the skull is penetrated (i.e., penetrating vs. nonpenetrating) or whether there is an associated hemorrhage.
