Recent studies using Wide Range Achievement Test-Revised (WRAT-R) Reading scores as estimates of premorbid abilities have demonstrated that distinct neuropsychological deficit profiles may be associated with specific cognitive disorders such as traumatic brain injury [Brain Inj. 9 (1995) 377] and lupus [Appl. Neuropsychol. 7 (2000) 96], and that these deficit scores predict both functional and ...

Clinicians should note that there is considerable variability in the reliabilities of the index and subtest scores derived from the third editions of the Wechsler Adult Intelligence Scale (WAIS-III) and the Wechsler Memory Scale (WMS-III). The purpose of this article is to review these reliabilities and to illustrate how they can be used to interpret change in patients' performances from test t...

Fourteen patients with progressive idiopathic dementia (PID) were compared with 14 normal controls on psychometric and laboratory measures of cognitive processes. The patients had significantly lower scores than controls did on the Wechsler Memory Scale (p < .001) and the Wechsler Adult Intelligence Scale (WAIS) Performance IQ (p < .01) but not on WAIS Verbal or Full Scale IQ nor on Digit Span ...

The Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV; D. Wechsler, 2003a) is often utilized to assess children with traumatic brain injury (TBI), although little information is available regarding its psychometric properties in these children. The current study examined WISC-IV performance in a sample of 61 children with TBI. As compared to the standardization sample, results in...

Because of difference in the toxicokinetic and pharmacokinetic characteristics of drugs and with respect to the high rate of benzodiazepine abuse in suicidal attempts, the trend of possible anterograde amnesia after recovery from benzodiazepine overdose were evaluated in Iranian patients. This was a prospective descriptive/analytic clinical trial, which was conducted, in Noor general teaching h...

Objective: This study aimed to investigate the verbal memory and working memory impairment in healthy siblings of patients with schizophrenia.&nbsp; Methods: The purpose of this study was to compare cognitive deficits in siblings of the patients with schizophrenia and control group. A total of 35 unaffected siblings of patients with schizophrenia were selected from the relatives of the pat...

scores at high levels of adaptive functioning will have poorer precision (i.e., higher SEMs) than those at low levels. SUMMARY. The Vineland–II was designed to be an easily used, standardized measure of key domains of adaptive behavior–Communication, Daily Living Skills, and Socialization–that play a prominent role in the diagnosis of mental retardation and other developmental disabilities. The...

The General Ability Index (GAI) is a composite ability score for the Wechsler Intelligence Scale for Children—Fourth Edition (WISC–IV) that minimizes the impact of tasks involving working memory and processing speed. The goal of the current study was to compare the degree to which the Full Scale IQ (FSIQ) and the GAI predict academic achievement in math and reading among a group of 88 children ...
