This article aimed to review the assessment and treatment of prospective memory impairment in individuals with traumatic brain injury. The three assessment techniques reviewed included questionnaires, psychological tests, and experimental procedures. Because interest in this area is relatively new, not many assessment techniques have been specifically developed to assess the various constructs of prospective memory. Of these, most lack a firm theoretical basis, adequate norms, and strong psychometric properties. Rehabilitative techniques, based on remedial and compensatory approaches, were then evaluated. Intervention methods that show promise include a prospective memory training approach, diary or memory notebook use, and electronic aids. Nevertheless, there is a need for further controlled trials with larger sample sizes to more thoroughly evaluate these methods. Self-awareness of memory impairment and generalisation of gains from treatment are another two issues identified as important for assessing and treating prospective memory impairment.

In December 1999, Greener, Enderby and Whurr reported the findings of their Cochrane review to assess the effects of formal speech and language therapy for people with aphasia following stroke. They concluded that aphasia therapy had not been shown to be “clearly effective or clearly ineffective within a randomised controlled trial (RCT)” (p. 1). Their conclusion led to much discussion among speech pathologists with some expressing grave concern that the outcome of the review would undermine the provision of services for people with aphasia and their carers. In this paper, evidence for the effectiveness of aphasia therapy that has been provided by published systematic reviews is critically explored. Clearly, challenges remain with respect to provision of evidence-based aphasia therapy. However, the weight of evidence accumulated over the years and synthesised in systematic reviews supports the broad conclusion that aphasia therapy is effective.

The posterior fossa region of the brain is a frequent site for tumour development in children, with over half of all childhood tumours occurring at this site. The principal brain structure implicated at this site is the cerebellum. Children treated for posterior fossa tumours can have a wide range of neurological and psychosocial problems. This paper describes the literature to date that addresses the neuropsychological impact of tumour and treatment in children with posterior fossa tumours. This paper reviews the literature on the causes of morbidity in this group. It discusses the recent research on the role of the cerebellum in outcomes and the studies that identify variables that interact with radiation effects.

Children with frontal lobe damage often appear to demonstrate remarkable recovery with few apparent signs of impairment immediately after injury. Over time, however, many develop increasing deficits in self-regulation, attention, and executive function, as well as in other higher functions. Current literature suggests that, in particular, these children seem to experience worsening socio-behavioural problems. Some case studies (Grattan & Eslinger, 1992; Anderson et al., 1999) describe individuals with childhood frontal lesions who developed severe social problems, deficits in executive functions and who also had lower than expected levels of moral reasoning. In the present study, social-adaptive behaviour and maturity of moral reasoning were measured in 16 children with focal frontal lesions and in 12 age-matched controls. Children with frontal lobe lesions had poorer adaptive behaviour ratings and lower levels of moral maturity than controls. These results support previous research suggesting that children with frontal lobe lesions have reduced social understanding and typically experience ongoing sociobehavioural problems.

Duncan's theory allows that executive function may be represented by a central and general construct of intelligence which was originally described by Spearman (Spearman, 1946). This theoretical critique discusses the three planks of evidence which appear to support this proposal: (1), the finding that intra correlations between “executive” tests are low and in one study equivalent to those with non-executive tasks, (2), that tests which are seen as most representative of Spearman's G may be used to identify patients with frontal lobe lesions and executive dysfunction and (3), the finding that functional neuroimaging studies which have used disparate tasks may show a similar region of activation within the prefrontal cortex. The evidence for these three findings is discussed in terms of their ability to support Duncan's theory.

Previous studies have indicated an increased likelihood of intellectual and memory impairments in children with epilepsy. It has been argued that early surgical intervention in children with intractable seizures might be advantageous to their development. We conducted a retrospective review of pre- and postoperative IQ and verbal memory scores in 16 paediatric patients who underwent temporal (N = 10) or extra-temporal (N = 6) focal surgery for epilepsy. Patients with an extratemporal seizure focus performed significantly worse than patients with a temporal lobe seizure focus on Full Scale IQ and Verbal IQ before surgery. Postoperatively a statistically significant decline in verbal memory, but not in any of the IQ indices was noticed in the extratemporal group. Individual outcome analyses revealed a significant decline in verbal memory in 22% of temporal lobectomy and 60% of extratemporal cases. Our review suggests that verbal memory but not IQ is vulnerable to postoperative decline in children who undergo focal extratemporal surgery for intractable epilepsy. The findings raise the possibility that extratemporal regions play a role in anterograde memory in children. Given the small number of subjects in this study, further investigations into the cognitive effects of paediatric surgical intervention are recommended.

The aim of this study was to develop and pilot a posttraumatic amnesia scale (PTA) scale for children aged between four and six years. The scale consists of seven orientation questions and five memory items modelled on the Westmead PTA Scale which assesses posttraumatic amnesia in children from eight years onwards and adults. The sample consisted of 45 four-year-olds, 82 five-year-olds and 49 six-year-old children from a variety of cultural and socioeconomic backgrounds. Children were recruited from hospitals, kindergartens and schools. Results were analysed across age groups using means and standard deviations. The orientation and memory items were analysed separately as well as in combination. Early analyses indicate that the majority of normal children in the four to 6 year age group can answer most of the orientation questions correctly and remember the memory stimuli from day to day. The results indicate that the Starship PTA Scale is suitable for young children aged 4 to 6 years. It is simple and quick to administer and utilises an operational definition of posttraumatic amnesia in terms of measuring continuous memory.

Findings are reported from the first examination of the Beardsworth Memory for Children's Faces Test (BMCFT) (Beardsworth & Zaidel, 1994) tested on a selected sample of 10 left (LATL) and 7 right (RATL) anterior temporal lobectomy patients an average of 7 years post surgery. No differences between LATL and RATL groups were found on immediate or delayed memory trials of the BMCFT. Verbal memory was assessed with a verbal analogue of this test, the Extended Verbal Paired Associates Test (EVPAT) specifically constructed for this study. Differences were obtained on the immediate (F = 5.17; p < .01) and delayed (F = 6.55; p < .01) memory trials of the EVPAT with LATL patients learning and retrieving fewer verbal associations than their right ATL counterparts. No differences were found on the memory decline to delayed recall scores on the EVPAT. The findings suggest that people who have left or right ATL in childhood cannot be distinguished on the basis of their immediate or delayed memory for paired faces an average of 7 years post-surgery. These results are consistent with the immediate memory performance of children 6 months post-surgery as reported by Beardsworth and Zaidel (1994), but are not consonant with the delayed memory performance of their children on this task. This indicates that left-right dissociations found in children on measures of delayed memory for faces 6 months post-surgery may represent a component of memory that is still in a state of recovery. The findings for the immediate memory trials of the EVPAT conformed to expectations and underscore the dependability of simple rote verbal memory tasks in dissociating left from right ATL 7 years post-surgery. The study addresses the issue of the recovery of immediate versus delayed memory and time of assessment post-surgery.

The present study investigated the ability of cerebrovascular accident (CVA) patients to perceive emotions portrayed by realistic stimuli. Statistical analyses demonstrated that CVA patients with damage to either the right or left cerebral hemisphere performed, on average, as well as controls did in perceiving emotions. However, a case study of one patient suggested that there may be a subset of CVA patients with right parieto-occipital damage who have deficits in the perception of negative emotions. The performance of this participant also indicated that deficits in emotion perception are ameliorated to some extent when patients are provided with realistic, complex stimuli that include a range of auditory and visual cues.

Functional magnetic resonance imaging (fMRI) has been recognised as a neuroimaging technique suitable for examination of higher cognitive function in children. It has been used to elucidate cognitive neural networks associated with various aspects of language function in several group and case studies of school-aged children. Language function has been lateralised and localised with fMRI in clinical samples, neurologically normal children and children with developmental language disorders. Issues of plasticity of language function during development and following injury have also been considered. Several paediatric case studies have also raised questions with respect to the interpretation of fMRI language activation. In spite of methodological challenges, fMRI has proved a useful technique for examination of the brain-behaviour relationship in developmental language functions. This paper reviews fMRI studies of language, including reading, in children.

Patients with acute brain lesions often demonstrate dramatic forms of visual neglect; however their unstable medical conditions and rapidly changing neglect make it impossible to carry out rigorous experimentation to test theories of neglect. Careful assessment of their disorders can, however, inform rehabilitation strategies, and stimulate tentative neglect hypotheses that can later be tested more rigourously on the much rarer patients who have persisting neglect. The neglect behaviours of two patients with acute lesions are described in terms of environment-centred and object-based frames of reference. TT, with a right parietal glioma, has difficulty describing unexpected details on the left sides of pictures, in contrast to SM, with a right frontal abscess, who describes pictures accurately. Both patients, however, show left-sided neglect when copying pictures. When asked to copy daisy pictures, including half daisies, TT copied half daisy heads, including half of the half daisies, but SM missed only whole daisy heads to the left of other daisies. Their different responses to these daisy pictures is tentatively explained in terms of their ability to perceive whether or not half daisies appear “ridiculous”. SM also embellished the right sides of her drawings, suggesting an interaction between this dysexecutive behaviour and neglect.
