Background: A high prevalence of dementia among Aboriginal and Torres Strait Islanders has been reported but knowledge of underlying causes and associations remains limited. Objective: To identify the prevalence of factors that may be associated with the categories of Major neurocognitive disorders (Major NCDs) in Aboriginal people living in residential aged care facilities in Alice Springs in the Northern Territory (NT). Design and Setting: This descriptive cross-sectional study analysed clinical file and cognitive assessment data of participants who were identified as having cognitive impairment between January and June 2016. Method: Screening for the presence of cognitive impairment using the Kimberley Indigenous Cognitive Assessment (KICA) was undertaken and 58 of 84 Aboriginal people were admitted to the study. Using a clinical file audit, diagnoses of Major NCDs consistent with the DSM-5 classification were made and the prevalence of factors possibly associated with these diagnoses described. Results: Fifty of the 58 participants were diagnosed with a Major NCD. The most frequent diagnoses were Major NCD due to vascular disease (30%), Major NCD due to Alzheimer's Disease (26%) and Major NCD due to brain injury (20%). Hypertension, Type 2 Diabetes Mellitus and alcohol misuse were commonly reported together with hypothyroidism, hypoglycaemia and vitamin D deficiency. Conclusion(s): This study identified possible associations with Major NCDs in this population as well as a different spread of Major NCD diagnoses to previous studies in Aboriginal populations. There is a need for further research to understand the causes of dementia in Australian Aboriginal people and to use this information to appropriately tailor treatment and prevention programmes.

Objective: To investigate trends in hospital admissions involving suicidal behaviour in the Northern Territory (NT) resident population over the period 2001-2013.Methods: Estimates of age-standardised rates and average changes in the annual rate of hospital admissions involving suicidal behaviour were calculated by socio-demographic characteristics and types of suicidal behaviour.Results: Overall rates for Indigenous admissions were 2.7 times higher than non-Indigenous admissions and had increased by almost twice as much. While male and female rates of admission were similar for both Indigenous and non-Indigenous residents, the average annual change in rates was greater for Indigenous females (13.4%) compared to males (8.8%) and for non-Indigenous males (7.7%) compared to females (5.2%). Younger and middle-aged Indigenous admissions experienced increasing rates of admissions, whilst trends were similar across age groups for non-Indigenous admissions. Admissions with a diagnosis of suicidal ideation increased the most across all groups. Trends in intentional self-harm admissions differed according to Indigenous status and sex.Conclusions: There have been substantial increases in hospital admissions involving suicidal behaviour in the NT, most markedly for Indigenous residents. Indigenous females and youth appear to be at increasing risk. The steep increase in suicidal ideation across all groups warrants further investigation. [ABSTRACT FROM AUTHOR]

Objectives: This article reviews the changing Aboriginal mental health service delivery model of Top End Mental Health Services, and highlights the importance of Aboriginal mental health workers in improving communication with Aboriginal patients. The Australian Integrated Mental Health Initiative Northern Territory Indigenous stream (AIMHI NT) is introduced. Method: Baseline measures of AIMHI NT in 2003, and findings from two clinical file audits (1996 and 2001) at Royal Darwin Hospital inpatient unit are presented. The files were audited for a range of assessment and treatment interventions. Results: The audits reveal significant improvements in Aboriginal inpatient care between 1995 and 2001. Conclusion: Aboriginal mental health workers provide essential services as cross-cultural brokers in the setting of Aboriginal mental illness. The improvements in care found in this file audit coincide with the commencement of employment of Aboriginal mental health workers in the inpatient unit. The AIMHI consultation reveals broad support for employment of more Aboriginal mental health workers in the Top End. [ABSTRACT FROM AUTHOR]
