Alzheimer's disease (AD) and subcortical vascular dementia (SVaD) are among the most prevalent dementias and they often show specific patterns of cognitive dysfunction. This study examined whether differences exist between groups on the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) that could assist with differential diagnosis.(More)
Although research on adults with frontal lobe epilepsy (FLE) has increased in recent years, delays in frontal lobe development preclude the generalization of these findings to children. This study compared children with FLE with typically developing children on cognitive and executive tests. Additionally, the differences between children with early and late(More)
A survey was sent to 500 members of the National Academy of Neuropsychology (NAN) in order to tally clinical test evaluation times. A return of 118 useable responses resulted in the table of "clinical times" (e.g., time required to administer, score, interpret, and report) presented in this paper. These are proposed as a practical guide for billing(More)
This study examined the inter-rater reliability (IRR) of the Clinical Dementia Rating (CDR) for patients with traumatic brain injury (TBI). The CDR is a commonly used rating of impairment, but there has been no research examining its utility in patients with TBI. It was hypothesized that the CDR would have good IRR when used with patients with TBI. Two(More)
A retrospective validation study of the Neurometric method of the Quantitative Electroencephalogram (QEEG) in predicting response to psychotropic medication was conducted. The clinical outcomes of 2 groups of patients were compared: those patients prescribed medication regimens that were concordant with the QEEG predictors vs. those whose medication(More)
The Halstead Category Test (HCT) is a neuropsychological test that measures a person's ability to formulate and apply abstract principles. Performance must be adjusted based on feedback after each trial and errors are common until the underlying rules are discovered. Event-related potential (ERP) studies associated with the HCT are lacking. This paper(More)
Presented normative data, collected on an unselected sample of 302 7- and 9-year-old children, for the Missouri Children's Behavior Checklist. Boys were found to be rated as more deviant than girls, while age, occupation of head of household, and estimated IQ were found to be unrelated to checklist ratings of deviant behavior. The use of a cutting point on(More)
The Category Test (CT) is a neuropsychological measure that taps into multiple domains of complex reasoning but yields a single error score, limiting the use of the test. In this study, three new CT scales were developed to assess specific aspects of executive dysfunction: Perseveration, Failure to Maintain Cognitive Set, and Inability to Recall and(More)
Administered the Missouri Children's Picture Series, a nonverbal objective test of personality to a group of normal (N = 119) children and a group of institutionalized (N = 77) aggressive children. Several of the test scales differed significantly between the two groups. The test scales of Aggression and Maturity showed the most consistent and largest(More)
The Booklet Category Test (BCT) is a neuropsychological test of cognitive dysfunction that provides only one overall error score indicative of global impairment. It does not, however, delineate specific domains that might be impaired. The aim of this study is to concurrently validate 13 new BCT subscales using legacy instruments in patients with(More)
