WAIS-III findings were reported for 150 litigants, classified into three groups according to severity of traumatic brain injury (TBI), and a general population control group. There was a significant "dose response" relationship between TBI severity and all Index/IQ scores. Effect size was greatest for the Processing Speed Index (PSI). Between group(More)
OBJECTIVE To examine the extent and nature of neuropsychological deficits in adolescents and young people with first episode psychosis (FEP), and to determine whether the pattern and extent of neuropsychological deficits varied according to diagnosis. METHOD A total of 83 FEP subjects aged 13-25 years, and 31 healthy controls completed a comprehensive(More)
OBJECTIVE This study explored the concurrent courses of the neuroanatomical and neuropsychological changes that occurred over the first 2-3 years of illness in patients with first-episode schizophrenia (FES). METHODS Fifty-two patients with FES underwent neuropsychological testing and a structural magnetic resonance imaging (sMRI) scan within three months(More)
This paper aimed to examine the relationship between the trichotomous symptom structure of psychopathology and neuropsychological functioning in young people with first episode schizophrenia (FES), most of whom were receiving atypical antipsychotic medication. This was with a view to providing insight into the underlying pathophysiology of the clinical(More)
OBJECTIVE To report on the relationship between quality of life (QOL), psychiatric symptoms and neuropsychological functioning in a sample of young people who have experienced a first episode of psychosis 2-3 years following initial presentation.

Wechsler Memory Scale-Third edition (WMS-III) performance in 25 mild traumatic brain injury (TBI) litigants who met the criteria for probable malingered neurocognitive dysfunction (MND) was compared with 50 nonmalingering subjects. The base rate for probable MND in the population studied was 27%. Overall, malingerers showed globally depressed memory(More)
Two methods of predicting premorbid WAIS-III Full Scale IQ, namely a demographic measure (DP IQ) and the Oklahoma Premorbid Intelligence Estimate-3 (OPIE-3), were assessed in three traumatic brain injury (TBI) groups of varying injury severity and normal controls. On the DP IQ, average scores were in keeping with the general population mean across all(More)
Published information pertaining to the clinical utility of the WMS-III in assessing memory impairment in traumatic brain injury (TBI) remains inadequate. WMS-III findings are reported for 180 litigants with post-acute moderate to extremely severe TBI, classified into three groups according to injury severity, and a healthy control group.
