Welcome to 2017. This promises to be an exciting year for Brain Impairment. First, we are delighted to announce the Special Issue on Disorders of Social Cognition; Advances in Theory, Assessment and Treatment guest edited by Professor Skye McDonald. The Editors wish to thank Professor McDonald for her hard work in organising an issue of the highest class. This issue will lead off Volume 18.

Social cognition can be impaired in a range of neuro-degenerative conditions, yet the impact of these difficulties on behaviour and social relationships is not yet fully understood. This study assessed social cognition in 27 participants with Dementia of the Alzheimer Type (DAT) and their co-residing partners (N = 27) and explored the relationships between social cognition, cognitive ability, relationship continuity and behaviour following diagnosis. In line with previous research, participants with dementia scored lower on social cognition tasks compared to their partners. Behaviour changes such as apathy, disinhibition and agitation in participants with dementia were significantly related to relationship continuity; however, no significant associations were found with measures of social cognition. The results of this study are discussed within a therapeutic context and in line with current guidelines and policies.

This issue of Brain Impairment celebrates the 40th anniversary of the Australasian Society for the Study of Brain Impairment through an invited Guest editorial by Dr Jan Ewing. Dr Ewing was a founding member of ASSBI, authored the first president's address to be published in Brain Impairment (Volume 1, Issue 1), and is the long-term chair of the ASSBI Publications Committee. Dr Ewing draws upon her long experience to address the theme ‘looking behind to look ahead’ in the Guest Editorial. A poem composed by Dr Ewing, titled Reminiscence, celebrates the past 40 years of ASSBI and is reproduced in this special issue. The remainder of this issue consists of five original research papers addressing stroke, followed by the presidential address and the usual other elements of each year's final issue including the abstracts from the 2017 ASSBI conference.

The Australasian Society for the Study of Brain Impairment (ASSBI) celebrated its 40th anniversary at the annual conference in Melbourne this year. The conference theme was apposite:

Social cognition refers to the ability to use social cues to infer the meaning and intentions behind the behaviour of others in order to respond in a socially adaptive manner. It is increasingly recognised that disorders of social cognition, including problems with emotion perception, theory of mind, conversational inference, morality judgements, decision making and social inhibition, characterise many developmental and psychiatric disorders and are highly relevant to many with acquired brain injuries or diseases, especially the frontotemporal dementias. This review provides an introduction and overview of the papers in this special edition on social cognition and places these in the context of other recent research. In doing so, several current issues in the clinical management of social cognition are delineated. Given that social cognition seems to be a sensitive predictor of psychosocial function, the assessment of social cognition is seen by many clinicians to be important although which profession is responsible is yet to be resolved. Issues in how social cognition are assessed are discussed, including the importance of context to social cognition, its interactive nature and the need to recognise influences such as family upbringing, gender and emotional state on social cognitive performance. There also needs to be development of tests that address all aspects of social cognition, including decision making and inhibition. Finally, this review discusses intervention research. Interventions are especially well developed in relation to schizophrenia, and less well developed in brain injury. These appear to be generally effective although treatments for emotional self-awareness are yet to be developed.

Purpose: To undertake a randomised controlled trial to test the benefits of cognitive training (CT) vs. cognitive stimulation (CS) on general cognitive function and memory in mild Alzheimer's disease (mAD).

Method: A consecutive series of 55 mAD outpatients was randomly allocated to one of the three conditions, namely two experimental interventions (CT and CS; 17 participants each) and a control dementia (no intervention) group (CD; 21 participants). Participants in the experimental conditions received a 4-month individual intervention programme.

Results: The participants in the CT condition demonstrated a large improvement in general cognitive state with moderate gains in areas of memory targeted by the intervention (semantic memory, naming and retrieval ability) 12 months after baseline measurement compared to the other two conditions. In addition, CT seemed to generalise the other cognitive abilities that were not directly targeted with small gains noted in other domains of cognition (prospective memory, face recognition, name a person) compared to CS and CD. Participants in both the CS and CD conditions showed significant general cognitive decline, even though CS was found to ameliorate the trajectory of this decline.

Objectives: This study examined the current assessment practices of clinicians working with people with social cognition impairment following traumatic brain injury.

Method: Two hundred and sixty clinicians completed an on-line survey that was disseminated through professional brain injury organisations. Of respondents around 90% were allied health clinicians, with the remainder comprising medical, nursing and academia.

Main outcomes: The four areas of social cognition that were routinely assessed across the disciplines were insight, disinhibition, anger and social adjustment. The least routinely assessed areas were theory of mind and alexithymia. The test suggested most likely to identify social cognition impairments was The Awareness of Social Inference Test, although only 8% of clinicians responded to this question. Clinicians preferred informal assessment methods over standardised assessment methods for identifying social cognition rehabilitation goals. Higher levels of education were associated with greater use of standardised assessment modalities. Whilst there was paucity of responses overall, TBI Express was most commonly used for social cognition rehabilitation.

Conclusions: Considering the high prevalence of social cognition impairments in this population, formal assessment is extremely limited. The under-utilisation of assessment tools is problematic for the assessment and rehabilitation initiatives offered to people with TBI. These results have implications for the training of clinicians working in brain injury rehabilitation.

Olfactory impairment in older adults is associated with cognitive decline. This study describes the development of a Brief Odor Detection Test (B-ODT), and its pilot administration in community-dwelling older adults. The study aimed at examining whether the test could differentiate older adults with very mild cognitive impairment from their cognitively healthy counterparts. The sample consisted of 34 older adults (22 women), aged from 65 to 87 years. Participants were divided into two groups according to their general cognitive functioning. Odor detection was measured via vanillin solutions at the following concentrations: 150 mg/L, 30 mg/L, 15 mg/L, 3 mg/L, and .03 mg/L. The first condition of the test involved a scale administration of vanillin solutions. The second condition examined the change in air odour and it required vanillin solution of 30 mg/L and a metric ruler of 30 cm. The examiner had to place the solution at a specific distance point from each nostril. Odour identification sensitivity was secondarily measured. The results showed statistically significant differences in odour detection threshold between the two groups. In the unirhinal testing, left nostril differences of the two groups were definite. Hence, the B-ODT seems a promising instrument for very early cognitive impairment screening in older adult population.

The primary objective of the current study was to determine if men and women with traumatic brain injury (TBI) differ in their emotion recognition and emotional inferencing abilities. In addition to overall accuracy, we explored whether differences were contingent upon the target emotion for each task, or upon high- and low-intensity facial and vocal emotion expressions. A total of 160 participants (116 men) with severe TBI completed three tasks – a task measuring facial emotion recognition (DANVA-Faces), vocal emotion recognition (DANVA-Voices) and one measuring emotional inferencing (emotional inference from stories test (EIST)). Results showed that women with TBI were significantly more accurate in their recognition of vocal emotion expressions and also for emotional inferencing. Further analyses of task performance showed that women were significantly better than men at recognising fearful facial expressions and also facial emotion expressions high in intensity. Women also displayed increased response accuracy for sad vocal expressions and low-intensity vocal emotion expressions. Analysis of the EIST task showed that women were more accurate than men at emotional inferencing in sad and fearful stories. A similar proportion of women and men with TBI were impaired (≥ 2 SDs when compared to normative means) at facial emotion perception, χ2 = 1.45, p = 0.228, but a larger proportion of men was impaired at vocal emotion recognition, χ2 = 7.13, p = 0.008, and emotional inferencing, χ2 = 7.51, p = 0.006.

Australasian Society for the Study of Brain Impairment (ASSBI) is deeply saddened by the death of Dr Kevin Walsh, at the age of 92, on 4 December 2017. Kevin has been one of the grandfathers of clinical neuropsychology and was the founder of ASSBI. After serving in the RAAF, he completed a medical degree in 1951 and went straight on to pursue his interest in the study of psychology, by completing Bachelor's and Master's degrees. Whilst assisting in psychosurgery, Kevin wrote his Master's thesis on the assessment of the effects of frontal lobe dysfunction, based on his studies of patients undergoing frontal leucotomies in the 1950s, a truly seminal work in elucidating frontal lobe functions. In 1961, he joined the Department of Psychology at the University of Melbourne. He taught neuropsychology and, forging a close collaboration with neurologist, Dr Peter Bladin, he established the first neuropsychology clinic at the Austin Hospital in Melbourne in 1974.

Objectives: To consider the strategies currently used by family care givers to manage challenging behaviour in the community following ABI, and to identify what supports are available that support family care givers in addressing this issue.

Research design: Delphi study.

Methods: Service providers (n = 8) and family care givers (n = 3) completed a three-round Delphi process with the aim of reaching consensus (75% agreement) regarding research objectives. Round 1 consisted of an open-ended questionnaire in which items were identified; these items were then rated in Round 2 and 3 using a Likert scale. Statistical aggregation then allowed for quantitative analysis.

Results: The findings suggest a number of behaviour management approaches are being used by family care givers, including basic antecedent strategies, agreeing with the person's demands, and medication. Consensus was reached that only two services in SA provide specific support to family care givers regarding behaviour management in the community: Families4Families Inc. (a peer support network) and Private Specialists (e.g., [neuro]psychologists and [neuro]psychiatrists).

Conclusions: Findings emphasise the need for more specialised services specific to educating and supporting family care givers in the management of challenging behaviours following ABI. These services should be accessible, centralised, and easy for family care givers to navigate.

Background: Depression and anxiety are the two most frequently studied emotional outcomes of stroke. However, few previous studies have been carried out at a population level or beyond 6 months post stroke. The aim of this study was to describe depression and anxiety across the first year following incident ischemic stroke (IS), and identify predictive factors in a population-based study.

Method: The Hospital Anxiety Depression Scale (HADS) was administered at baseline (within 2 weeks of onset), and again at 1-month, 6-months and 12-months after IS in a sample (N = 365) drawn from a population-based study.

Results: Over 75% of those assessed experienced depression or anxiety symptoms below cut-offs for probable disorder across the year post stroke. Moderate to severe symptoms for anxiety were approximately twice as likely (range 4.1%–10.6%) as compared to depression (range 2.5%–5.0%) at each assessment. The greatest improvement in anxiety occurred within the first month post stroke. In contrast, the greatest reduction in depression occurred between 1- to 6-months post stroke.

Conclusions: Anxiety symptoms in the moderate to severe range were twice as common as depression, and improved over the first month post stroke, whilst depression symptoms persisted for up to 6 months, indicating a need to target these two issues at different points in the recovery process.

Background: Acquired brain injury is the leading cause of death and disability in children after infancy. Childhood brain injury has long-term consequences for children and parents, including challenges with returning to school, ongoing health and behaviour concerns, family functioning and demands on carers. Community-based case management interventions are a vital contribution to community supports.

Aims: This scoping study aims to scope and map the literature on case management, to identify how case management is described in the literature for children and adolescents with acquired brain injury (0–17 years).

Methods: A scoping review was completed of published articles on case management from four major databases (CINAHL, MEDLINE, PUBMed and Embase) between 2005 and 2015. Articles were selected against inclusion criteria and reviewed.

Results: Eight articles of 2688 records met the inclusion criteria and were reviewed. Case management was provided by case managers and other health professionals. The case management interventions described were mapped to the International Classification of Health Interventions and the Brain Injury Case Management Taxonomy (BICM-T). Case management addressed a range of needs including return to school, family issues and ongoing medical needs. There were anecdotal reports of effectiveness of case management during the return to school process.

Conclusion: This scoping study reveals a lack of information on this topic. Improved reporting of case management interventions and more research on case management is needed for children and adolescents with brain injury.

Recognition of facial affect has been studied extensively in adults with and without traumatic brain injury (TBI), mostly by asking examinees to match basic emotion words to isolated faces. This method may not capture affect labelling in everyday life when faces are in context and choices are open-ended. To examine effects of context and response format, we asked 148 undergraduate students to label emotions shown on faces either in isolation or in natural visual scenes. Responses were categorised as representing basic emotions, social emotions, cognitive state terms, or appraisals. We used students’ responses to create a scoring system that was applied prospectively to five men with TBI. In both groups, over 50% of responses were neither basic emotion words nor synonyms, and there was no significant difference in response types between faces alone vs. in scenes. Adults with TBI used labels not seen in students’ responses, talked more overall, and often gave multiple labels for one photo. Results suggest benefits of moving beyond forced-choice tests of faces in isolation to fully characterise affect recognition in adults with and without TBI.

The Bangor Gambling Task (BGT, Bowman & Turnbull, 2004) is a simple test of emotion-based decision making, with contingencies varying across five blocks of 20 trials. This is the first study to characterise BGT performance in survivors of traumatic brain injury (TBI) relative to healthy controls. The study also aimed to explore sub-groups (cluster analysis), and identify predictors of task performance (multiple regression). Thirty survivors of TBI and thirty-nine controls completed the BGT and measures of processing speed, pre-morbid IQ, working memory, and executive function. Results showed that survivors of TBI made more gamble choices than controls (total BGT score), although the groups did not significantly differ when using a cut-off score for ‘impaired’ performance. Unexpectedly, the groups did not significantly differ in their performance across the blocks; however, the cluster analysis revealed three subgroups (with survivors of TBI and controls represented in each cluster). Findings also indicated that only age and group were significant predictors of overall BGT performance. In conclusion, the study findings are consistent with an individual difference account of emotion-based decision making, and a number of issues need to be addressed prior to recommending the clinical use of the BGT.

Transitional living service (TLS) programmes for adults with an acquired brain injury are considered an important part of rehabilitation. However, considerable variability exists in the design and structure of these services, with limited research to guide the development of a programme based on best evidence. A scoping literature review was completed to answer the question ‘What is known about TLS programmes for adults with an acquired brain injury?’ Four electronic databases were systematically searched, followed by a grey literature search (from 1996 to 2015). 3183 articles were screened and 13 articles were included in the final review. Themes that emerged from the literature include the types of residents using TLS programmes, the subjective experience of residents and staff, intervention approaches, programme staffing, and programme outcomes. The research reviewed supports the use of TLS programmes to maximise functional independence and community integration of individuals with an acquired brain injury. Clinical practise recommendations were developed to help support implementation of TLS programmes based on best evidence, these included: to use multiple outcome measures, implement collaborative goal setting, support generalisation of skills learnt in the TLS to the home environment and for eligibility criteria for these programmes to include individuals across all phases of recovery.

Some risk factors of stroke may play a role in white matter hyperintensity (WMH). Metabolic syndrome (MetS) is a recognised risk factor of stroke, but it is controversial whether MetS is also associated with WMH. We examined the association of MetS with the prevalence of WMH in acute stroke patients. We conducted a cross-sectional study in 246 acute ischemia stroke patients. The patients with acute stroke were clinically evaluated, including waistline circumference, blood pressure, glycaemia, serum triglyceride and high density lipoprotein cholesterol level. The degree of WMH was assessed by Fluid-attenuated inversion recovery (FLAIR) sequence of magnetic resonance imaging (MRI) scans. MetS was diagnosed using the criteria by the National Cholesterol Education Adult Treatment Panel III. MetS was the independent variable evaluated in Binary regression analyses. It is found that old age (>60 years old), MetS and smoking were significantly associated with WMH in univariate analysis (p < .05). Spearman rank correlation showed that old age and MetS are related to WMH (r = 0.18, p = .005 and r = 0.18, p = .004, respectively). Hypertension is weakly but not significantly associated with WMH in correlation analysis (r = 0.11, p = .08). In multiple regression analysis, age and MetS remained independently associated with WMH (OR = 7.6, 95% CI 0.2–0.7 and OR = 11.7, 95% CI 0.1–0.5). Hypertension and hyperglycaemia tend to be associated but not significantly with WMH (p = .07, p = .08). Other MetS components such as large waist circumference and dyslipidaemia showed no association with WMH. After adjustment for age, WMH is significantly associated with MetS in stroke patients. Hypertension and hyperglycaemia tend to associated but not significantly with WMH in stroke patients.

Background: Speech pathologists work to optimise communication and reduce the emotional and social impact of communication disability in patients with aphasia but need evidence-based interventions to effectively do so.

Objective: This phase 1 study aims to evaluate an Australian speech-pathology-led intervention called the Aphasia Action, Success, and Knowledge (Aphasia ASK) programme for patients with aphasia early post stroke.

Methods: A convergent parallel mixed-methods design was utilised. The intervention included up to six individual face-to-face sessions with seven participants with aphasia and their nominated family member(s). Quantitative outcomes assessing mood, quality of life, and communication confidence were conducted for the participants with aphasia. Follow-up interviews were conducted with both participants with aphasia and family members to determine their perceptions of the programme.

Results: Significant improvements were found in communication confidence and mood after treatment and the gains were maintained at 3-month follow-up. Participants with aphasia and their family members reported a good level of satisfaction with the programme.

Conclusions: Findings suggest the Aphasia ASK programme is a suitable intervention with positive initial outcomes for people with aphasia. A larger scale evaluation with a greater variety of participants is now required. An Australian cluster randomised control trial is planned.

Social disinhibition difficulties are common following traumatic brain injury (TBI). However, clinically sensitive tools to objectively assess the difficulties are lacking. This study aimed to pilot a new clinical measure of social disinhibition, the social disinhibition task (SDT). Whether social disinhibition is dependent on the type of social information judgements required and whether disinhibited responses can be adjusted with additional guidance were also examined. Participants were 31 adults (25 Male) with moderate-to-severe TBI and 22 adult (17 Male) healthy control participants. Participants viewed scenes of complex social situations and were asked to describe a character in them (Part A), describe a character while inhibiting inappropriate or negative responses (Part B), and describe a character while not only inhibiting negative responses, but also providing positive responses (Part C). One-half of the items contained a faux pas requiring participants to make inferences about a character's mental state. TBI and control participants responded similarly to Part A, although control participants responded less positively than TBI participants in the faux pas items. TBI participants were significantly impaired on Part B indicating they experienced difficulties in inhibiting automatic responding. TBI participants were however able to adjust their responding in Part C so that they respond similarly to the control participants. Between group differences were not detected in reaction time. Overall, the SDT appears to be suitable to detect social inhibition difficulties in clinical settings and provides a new direction for remediation of the difficulties in individuals with TBI.
