320 Abstracts of 16th Annual Meeting elements of the complex figure was the most effective strategy employed by subjects in this sample because it placed fewer demands on the cognitive abilities typically corrupted in neuropsychiatric patients (i.e., attention and working memory). In summary, the current study provided initial clinical support for the usefulness of the fragmentation scoring system as a measure of visual organization and encoding processes on the ROCE Fuller, K. H., Monna, W., David, W., & Sanderlin, M. Neuropsychological Functioning in Chronic Post-Traumatic Stress Disorder (PTSD) Patients With and Without Comorbid History of Traumatic Brain Injury. Evaluation of possible cognitive dysfunction is of importance in the assessment of combat veterans presenting with symptoms of PTSD. Presenting problems of these patients include attention, concentration and memory difficulties which are generally similar to those asso- ciated with moderate to severe anxiety disorders. However, this population is also charac- terized by increased prevalence of cognitive risk factors, including traumatic brain injury (TBI). The purpose of the current study is to provide a comparison of the neuropsychological functioning between chronic PTSD patients with and without a history of TBI. Data regarding cognitive test performance was gathered from consecutive admissions to an inpatient treatment program for combat related PTSD (n = 145), and this sample was divided into groups based on reported history of TBI (defined as LOC > 1 hour). Neuropsychological test battery included measures of general intelligence (SILS), attention/concentration (stroop, trails), Memory (WMS-R), and abstract reasoning (WAIS-R similarities). Results are pre- sented as a series of means and standard deviations for these two groups, which are designed to assist clinicians in interpreting test results obtained from individuals reporting PTSD symptoms. Both groups were found to differ significantly from expected values based on previously published normative information. Furgueson, C. The Efficacy of Ritalin for ADHD: Issues of Intelligence and Executive Function. This study examined the effectiveness of Ritalin as a treatment for disorders of executive function, attention, and concentration among children diagnosed with Attention Deficit Hyperactivity Disorder (ADHD), ADHD and Oppositional Defiant Disorder, or ADHD and Conduct Disorder. It was hypothesized that treatment would result in increased executive function, self-monitoring, and goal directed behavior. All subjects were randomly assigned to a treatment (n = 25) or a control group (n = 25), and tested pre and post treatment. After controlling for Verbal IQ differences between the two groups, no treatment effect was demonstrated. Although Ritalin has been shown effective in the treatment of behavior problems associated with ADHD, this study suggests that this effect does not extend to the cognitive aspects of this disorder. Gage, R., & Hartlage, L. C. Utility of Microsmia Testing in Litigated Minor TBI Cases. In litigated cases involving traumatic brain injury, there is typically need to document both whether brain injury has occurred; and whether a trauma or injury at issue was etiologic in whole or part in he event brain injury is documented. Considerable experience and research with CT and related neurodiagnostic procedures have indicated their general lack of sensi- tivity to and utility for such purposes. In deceleration type injury such as is common in many motor vehicle injuries, whether or not contact between skull and some external object has occurred, there is potential for tear injury involving anterior portions of the brain abrading bony orbit surfaces. Although assessment of such injury is not traditionally included in neuropsychological examination it can be easily incorporated into comprehensive neurop-
