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:

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.

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.

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.

With visible disabilities, observers tend to overgeneralise from the disability. In contrast, with invisible disabilities such as traumatic brain injury and stroke, observers often fail to allow for challenges resulting from the disability. Persons who have suffered a stroke claim that people misunderstand their symptoms and stigmatise them as a result of these symptoms. This misunderstanding, which happens particularly with young survivors of stroke, may reflect people's causal attributions for symptoms that follow a stroke. Using a scenario design, this cross-sectional study examined whether people attribute ambiguous symptoms that may result from stroke to other causes (the stroke survivor's personality and age) and whether these attributions reflect the age of the stroke survivor. Participants (N = 120) read scenarios describing a male who was aged either 22, 72, or whose age was unstated and who showed four symptom changes: fatigue, depression, irritability and reduced friendships. For each symptom change, participants rated three causal attributions: the person's age, his personality and stroke. The age of the person in the scenario affected attributions; when the person in the scenario was 22, participants attributed his symptoms significantly more to his personality than to his age or stroke, whereas when he was 72, participants attributed his symptoms more to his age than to his personality or stroke and when his age was unstated, they attributed his symptoms equally to age, stroke and personality. Because misattributions for stroke symptoms hinder rehabilitation, therapy can target people's misattributions to enhance rehabilitation for survivors of stroke.

Management of cognitive difficulties is a significant unmet need for individuals with stroke. Incorporating multiple functions, including memory aids and communication tools, smartphones have potential to improve everyday cognitive function and independence in daily activities post-stroke. We aimed to investigate patterns of smartphone use, facilitators and barriers to use, and relationships between smartphone use and daily functioning. Twenty-nine participants with stroke and 29 comparison participants with no history of neurological conditions completed measures of smartphone use, objective and subjective cognitive function, mood and community integration. The majority of participants used smartphones, though the proportion of users was lower in the stroke group (62%) than the comparison group (86%). Older participants were less likely to use smartphones. Using apps that support memory was a main benefit of smartphone use post-stroke. In the stroke group, frequent users of memory apps had significantly fewer motor symptoms (d = 1.20), and higher productivity (d = 0.84). Stroke survivors identified difficulty learning how to use smartphones, but only one participant had assistance with this from a clinician. These results suggest that smartphones have potential as assistive technology post-stroke, however, support in using them is essential, particularly for older individuals with motor dysfunction.

Our ability to interact appropriately in everyday interpersonal situations is fundamental to successful social integration. Impaired pragmatic competence correlates significantly and substantially with indices of social function across several domains for adults with acquired neurological disorders. In particular, evidence supports the negative impact of pragmatic impairments on the development and maintenance of relationships and community integration more generally.

Pragmatic language competence sits in a complex, multifactorial space characterised by interacting associations with cognitive and psychological functions and social and environmental parameters. This complexity is evident in much of the research seeking to unravel the nature and magnitude of interactions between pragmatic language competence and social outcomes in adults with acquired neurological disorders.

Over recent years our understanding of the impact of pragmatic impairments on social outcome has benefited substantially from inclusion of the insider's perspective in our research evidence base. Indeed, a methodological inclusion of constructivist paradigms has enabled the development of a rich understanding of the devastating social impact of impaired pragmatic competence.

The aim of this paper is to review pragmatic language impairment in the context of traumatic brain injury (TBI) and detail its impact on social functioning from the perspectives of people with TBI and their intimate partners/spouses and friends. With these perspectives as background, the paper concludes with consideration of therapeutic developments and a brief look at a novel intervention designed to reduce the negative impact of pragmatic deficits and improve functional language use following TBI.
