abstract = {OBJECTIVE: Computerized neurocognitive testing (CNT) appears to be suited to measure relatively mild degrees of neurocognitive impairment in circumstances where speed, efficiency, and low cost are important. Computerized tests are used in the evaluation and management of patients who have had mild brain injuries; the objective is to determine if computerized testing is equally reliable and valid in the evaluation of patients who have had more severe brain injuries. DESIGN: A cross-sectional, naturalistic study of brain injury patients compared with normal controls. SETTING: An outpatient neuropsychiatry clinic. PARTICIPANTS: 141 patients, aged 18-65 years, who had sustained traumatic brain injuries (TBIs): 13 patients with postconcussion syndrome; 15 who had recovered from mild brain injuries; 85 patients who had had severe brain injuries, but who had recovered, and were living independently; and 28 severe brain injury patients who were unable to live without assistance; compared with 145 normal controls. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: The CNS Vital Signs (CNS VS) battery is a PC-based system that includes tests of verbal and visual memory, psychomotor speed, complex attention, reaction time, and cognitive flexibility. RESULTS: Performance on the CNS VS battery was related to severity of brain injury and degree of recovery. Tests of psychomotor speed and cognitive flexibility were the most relevant to TBI status. Patients who had recovered from mild brain injuries scored almost as well as normal controls. The Neurocognition Index (NCI), a summary score based on performance on all the tests in the battery, was 100 for normal controls and 98 for recovered mild brain injury patients. Postconcussive patients scored 82 on the MCI, and severe brain injury patients scored 66 on the NCI if they were living independently and 47 if they were not. CONCLUSIONS: Computerized tests like CNS VS allow clinicians the advantage of precise neurocognitive measurement in the service of diagnosis and appropriate treatment. CNTs are never going to replace the flexibility or comprehensiveness of conventional neuropsychological testing, but they have a role to play in circumstances where a full test battery is not feasible, such as screening and serial assessment.},

abstract = {OBJECTIVE: To evaluate the concussion history of young athletes using three questions on the preparticipation screening (PPS) and a concussion symptom survey (CSS). DESIGN: Descriptive survey. SETTING: Mass high school PPS. PATIENTS OR OTHER PARTICIPANTS: Five hundred twenty young athletes. INTERVENTIONS: Athletes were asked about their concussion history using three different questions on the PPS. The CSS, a list of concussion-related symptoms, was also given to assess the history of concussion-related symptoms associated with a previous injury to the head. MAIN OUTCOME MEASURES: Positive concussion history was determined as a positive response on one of the three PPS questions or any one of the CSS responses and reported as frequencies and percentages. Kappa coefficients were used to evaluate the agreement between the responses on the three PPS questions. RESULTS: There was little agreement among the three PPS questions, with kappa coefficients ranging from kappa = -0.018 to 0.342. Analysis of the CSS revealed that 286 athletes (55.0%) reported having at least one concussion symptom after a head injury. Of those reporting symptoms, 86.4% did not report a concussion history in sport, and 92.7% did not report a concussion history in recreational activities. CONCLUSIONS: The identification of concussion history may depend on the phrasing of questions on the PPS. Simply asking an athlete whether they had a concussion may not adequately identify athletes with concussion histories. Although recommendations have been made to avoid the terminology of ding and bell rung, it seems these terms may be needed to ensure adequate reporting of previous concussions in young athletes.},

abstract = {Accurately documenting cognitive change is important, as neuropsychologists are routinely asked to determine cognitive change following disease progression or medical intervention. Computerized testing batteries, such as the Automated Neuropsychological Assessment Metrics (ANAM), are good tools for assessing change, because they allow for randomization of stimuli, creating near limitless alternate forms and reducing practice effects. The question remains, however, as to how best to determine reliable change in performance using ANAM. The current study compared the use of Reliable Change Index (RCI) and regression based methods (REG) calculated from 28 individuals with migraine. These methods then were applied to an independent sample of 25 individuals with migraine assessed with ANAM at baseline, headache, and following pharmacologic treatment. Traditional repeated measures analyses revealed declines in cognitive efficiency following migraine onset on two of four ANAM tasks and significant improvement on all ANAM tasks following treatment. Rates of deterioration and improvement did not significantly differ between RCI and REG methods, although were slightly different across the ANAM tasks used in this study. A combined ANAM score categorized the most individuals as demonstrating cognitive change, revealing that 60% of subjects declined in performance following headache and 84% improved following migraine treatment.

The CTIP consists of three computerized programs that progressively increase the amount of information that is processed. Results of the current study demonstrated that RT increased as the difficulty of the CTIP tests increased (known as the complexity effect), and as severity of injury increased (from mild to severe TBI). The current study also demonstrated the importance of selecting a non-biased measure of variability. Overall, findings suggest that the CTIP is an easy to administer and sensitive measure of information processing speed.},

abstract = {OBJECTIVE: Neuropsychological testing has been advocated as an important tool of proper post-concussion management. Although these measures provide information that can be used in the decision of when to return an individual to previous levels of physical activity, they provide little data on motor performance following injury. The purpose of this investigation was to examine the relationship between measures of dynamic motor performance and neuropsychological function following concussion over the course of 28 days. METHODS: Participants completed two experimental protocols: gait stability and neuropsychological testing. The gait stability protocol measured whole-body centre of mass motion as subjects walked under conditions of divided and undivided attention. Neuropsychological testing consisted of a computerised battery of tests designed to assess memory, reaction time, processing speed and concussion symptoms. Correlation coefficients were computed between all neuropsychological and gait variables and comparisons of neuropsychological and gait stability post-concussion recovery curves were assessed. RESULTS: Dynamic motor tasks, such as walking under varying conditions of attention, are complex and demanding undertakings, which require a longer recovery time following a concussion than cognitive measures. Little statistical relationship was found between the neuropsychological and gait variables, and the recovery curves of neuropsychological and gait domains were observed to be independent. CONCLUSIONS: In order to fully examine the effects of concussion and determine the optimal time for a safe return to activity, a multi-factorial approach, including both cognitive and motor tasks, should be employed.},

abstract = {The goal of the current investigation was to probe the deficits in the alerting, orienting and executive components of visuospatial attention in individuals who have recently suffered a mild traumatic brain injury (mTBI) and to assess the rate and degree of recovery for each of these components over a month post-injury. A group design was employed to assess and compare the performance of participants (12 males, 8 females; mean age: 21 +/- 1.74 years) identified with mTBI relative to control subjects matched for gender, age, height, weight and activity level. Participants performed the attentional network test, designed to isolate the constituents of attention into alerting, orienting and executive components. Reaction times (RTs) and response accuracy were the main dependent variables. The results showed that the orienting and executive components were significantly affected by mTBI immediately after the injury, whereas the alerting component was not. Furthermore, participants with mTBI recovered from the deficits in the orienting component of attention within a week of their injury, whereas the deficits in the executive component remained throughout the month post-injury. In addition, the RT cost to generate accurate compared with inaccurate responses was significantly larger in participants with mTBI than in controls, and this difference was maintained throughout the 1 month testing period. These findings indicate that the regions of the brain associated with the orienting and executive components of visuospatial attention may be most susceptible to neural damage resulting from mTBI. Moreover, the lack of recovery in the executive component indicates that the degree and time course for recovery may be regionally specific.},

abstract = {OBJECTIVE: Balance deficits in individuals experiencing mild traumatic brain injury have been documented in numerous recent studies. However, long-lasting balance deficits and specific mechanisms causing these deficits have not been systematically examined. This article aimed to present empirical evidence showing destabilizing effects of visual field motion in concussed individuals up to 30 days postinjury. METHODS: Sixty student athletes participated in the pilot (n = 12) and major experiments (n = 48) before injury. Eight of these 48 subjects who experienced mild traumatic brain injury in athletic events were tested again on Days 3, 10, and 30 after the incident. Postural responses to visual field motion were recorded using a virtual reality environment in conjunction with balance (AMTI force plate) and motion tracking (Flock of Birds) technologies. RESULTS: The area of the center of pressure during upright stance did not change from Day 3 to 30 postinjury with respect to pre-injury status (P \> .05). However, balance deficits induced by visual field motion were present up to 30 days postinjury. Destabilizing effect of visual field motion was observed via significant increase of the center of pressure data (P \< .05) and reduced coherence value. CONCLUSION: Our data suggest the presence of residual sensory integration dysfunction in concussed individuals at least 30 days postinjury and may indicate a lower threshold for brain reinjury.},

DATA SOURCES: The relevant literature was searched through the use of Medline (1966 to 2004), Google and Sport Discus (1975 to 2004) searches, hand searches of journals and reference lists and discussions with experts and sporting organisations worldwide. DATA SYNTHESIS/METHODS: Consensus recommendations are summarized. No formal statistical analysis is presented RESULTS: Although pre-participation examinations are widely performed, there are no evidence-based guidelines to direct physicians as to the minimum requirements for the baseline assessment of head injury. CONCLUSIONS: Expert consensus would suggest that a baseline neuropsychological examination, preferably using a computerised test battery, should be performed in order to guide return to play following subsequent concussive injuries. In addition, there are important medicolegal considerations in regard to the value of a documented assessment both at the start and end of an athlete's career with any team. [References: 19]},
