Dr Moyra Mortby is a Psychologist specialised in neuropsychiatric symptoms in dementia and pre-clinical stages of dementia and is an NHMRC-ARC Dementia Research Development Fellow. She was awarded her PhD with Laudatio Magna Cum Laude from the University of Zurich, Switzerland for her research on apathy and depression in Mild Cognitive Impairment and Alzheimer’s disease, and completed her MSc in Research Methods in Psychology and BSc in Criminology and Psychology both at Keele University, UK.

Her research program focuses on neuropsychiatric symptoms in dementia and pre-clinical stages of dementia, neuroimaging and epidemiology. 2015 International Society to Advance Alzheimer’s Research and Treatment (ISTAART) and the Neuropsychiatric Syndromes (NPS) in Neurodegenerative diseases Professional Interest Area (PIA) New Investigator Award.

Her research program is structured around 4 key areas which aim to: 1) improve our understanding of dementia, its risk factors and trajectories; 2) better understand the impact of neuropsychiatric symptoms on dementia trajectories, quality of life and the provision of formal and informal care; 3) validate the concept of Mild Behavioural Impairment as a pre-clinical stage of dementia; and 4) develop and evaluate interventions to reduce neuropsychiatric symptoms associated with dementia, improve quality of life for people living with dementia and those providing care and develop useful support mechanisms.

CURRENT PROJECTS

Behavioural Symptoms in Dementia (BeSyDe)

It is estimated that 1.2 million Australians are currently caring for someone with dementia. Caring for somebody with dementia can become more complicated by the presence of behavioural problems (e.g. depression, anxiety, apathy, aggression) in the person with dementia. These behavioural problems can contribute significantly to carer burden and distress. This study aims to improve our understanding of how interactions between the carer and the care-recipient affect behavioural problems in dementia. A better understanding of these interactions will help us develop programmes which can be used to assist the carer and those suffering from dementia to minimise the negative impact of problem behaviours in dementia.

BPSD PLUS: A person-centred approach to managing behavioural and psychological symptoms of dementia

Rates of behavioural and psychological symptoms of dementia (BPSD) amongst people living in residential aged care facilities (RACF) are high. Over 90% of Australian aged care residents exhibit clinically significant BPSD. Physical aggression, agitation and disinhibition, especially when severe, are difficult to manage and can put patients, carers and other residents at risk. Management of BPSD has recently become a focus of attention for the Australian Government, especially in relation to inappropriate overprescribing of antipsychotics. The discrepancy between international and national recommendations and the continued over-prescription of medication to manage BPSD must be addressed. Australia urgently needs better programs to support RACF to implement non-pharmacological, cost-effective management programs.

Special Issue on mild behavioral impairment and non-cognitive prodromes to dementia.

Mortby ME, Lyketsos CG, Geda YE, Ismail Z

This Special Issue provides a systematic examination of the neuropsychiatric symptoms (NPS) and non-cognitive prodromes of dementia, with an eye toward validating the construct of mild behavioral impairment (MBI).

Dementia clinical trial implications of mild behavioral impairment.

Mortby ME, Black SE, Gauthier S, Miller D, Porsteinsson A, Smith EE, Ismail Z

The World Alzheimer Report 2016 estimated that 47 million people are living with dementia worldwide (Alzheimer's Disease International, 2016). In the inaugural World Health Organization Ministerial Conference on Global Action against Dementia, six of the top ten research priorities were focused on prevention, identification, and reduction of dementia risk, and on delivery and quality of care for people with dementia and their carers (Shah et al., 2016). While the Lancet Neurology Commission has suggested that even minor advances to delay progression or ameliorate symptoms might have substantial financial and societal benefits (Winblad et al., 2016), advances have been slow.

Prevalence estimates of mild behavioral impairment in a population-based sample of pre-dementia states and cognitively healthy older adults.

Mortby ME, Ismail Z, Anstey KJ

This study presents the first population-based prevalence estimates for MBI using the recently published ISTAART-AA diagnostic criteria. Findings indicate relatively high prevalence of MBI in pre-dementia clinical states and amongst cognitively healthy older adults. Findings were gender-specific, with MBI affecting more men than women. Knowing the estimates of these symptoms in the population is essential for understanding and differentiating the very early development of clinical disorders.
