Telephone cognitive screening with older Aboriginal Australians: A preliminary study.

Objectives: Cognitive screening via telehealth is increasingly employed, particularly during the COVID-19 pandemic. Telephone adaptations of existing cognitive screening tests must be validated across diverse populations. The present study sought to evaluate an existing 26-point telephone adaptation of the Mini-Mental State Examination (tMMSE) in a sample of older Aboriginal Australians.

Dementia Incidence, Genotype, and Risk Factors for Cognitive Decline in Aboriginal Australians: A Longitudinal Cohort Study.

Background And Objectives: Aboriginal Australians are disproportionately affected by dementia, with incidence in remote populations approximately double that of non-Indigenous populations. This study aimed to identify dementia incidence and risk factors in Aboriginal Australians residing in urban areas, which are currently unknown.

Methods: A population-based cohort of Aboriginal Australians ≥60 years of age was assessed at baseline and 6-year follow-up.

Mild cognitive impairment in Aboriginal Australians.

Introduction: Aboriginal Australians have among the highest rates of dementia worldwide, yet no study has investigated the subtypes, risk factors, or longer term outcomes of mild cognitive impairment (MCI) in this population.

Methods: A total of 336 community-dwelling Aboriginal Australians aged ≥60 years participated in a longitudinal study, completing a structured interview at baseline. MCI (amnestic subtype, aMCI; non-amnestic subtype, naMCI) and dementia were diagnosed via cognitive screening, medical assessment, and clinical consensus.

Factors Associated with the High Prevalence of Dementia in Older Aboriginal Australians.

Dementia prevalence in Aboriginal and Torres Strait Islander Australians is three to five times higher than the general Australian population. A better understanding of the underlying biomedical and social risk factors is needed to guide dementia prevention in Aboriginal Australians. The current study is the first to examine potential risk factors for dementia in the majority urban and regional population, with a representative sample of 336 Aboriginal Australians aged 60 years and older.

Slow gait speed is associated with executive function decline in older people with mild to moderate dementia: A one year longitudinal study.

Objectives: This study aimed to document change in neuropsychological, physical and functional performance over one year and to investigate the relationship between baseline gait speed and cognitive decline in this period in older people with dementia.

Methods: One hundred and seventy-seven older people with dementia (Mini-Mental State Examination 11-23; Addenbrooke's Cognitive Examination-Revised <83) residing in the community or low level care facility completed baseline neuropsychological, physical and functional assessments. Of these, 134 participants agreed to reassessment of the above measures one year later.
