Overview

Dr Nadeeka Dissanayaka is a Senior Research Fellow leading the Neuro Mental Health research program within Clinical Neurosciences theme at the University of Queensland Centre for Clinical Research. She is an affiliate research fellow at School of Psychology, UQ, and Department of Neurology, Royal Brisbane & Women’s Hospital. Dr Dissanayaka is a current recipient of the NHMRC Boosting Dementia Research Leadership Fellowship and Lions Medical Research Fellowship. Her research involves multidisciplinary areas ranging from basic science (eg: pharmacology, physiology, genetics) to clinical science and medicine (eg: epidemiology, psychology, psychiatry, neurology, neurosurgery, cognitive neuroscience, neuroimaging and addiction).

Dementia and Parkinson's disease are key areas of Dr Disssanayaka's research. Her primary research themes include:

1. Diagnosis and Treatment of Anxiety and Depression in Dementia

2. Neuropsychiatric Manifestations in Parkinson's disease including anxiety, depression, cognitive dysfunction, sleep and impulse control disorders.

Research Interests

  • New diagnostic methods to identify anxiety in dementia and Parkinson's disease
  • Neuroimaging (EEG and fMRI) and psychophysiological markers
  • New psychological treatments using innovative technologies such as telehealth, virtual reality and mobile phones
  • Novel psychosocial interventions in residential aged care facilities
  • Adverse effects of pharmacological treatment including prescription of psychotropic medication in elderly

Research Impacts

Research Output: Dr Dissanayaka is the principal investigator of the Australian Mental Dysfunction in Dementia Network (MDDN) and Improving Diagnosis and Treatment of Anxiety in Parkinson’s disease (IDATA-PD) study. She is the developer of a new Parkinson’s disease-specific anxiety inventory for psychotherapy and co-author of 5 new psychotherapy manuals (1 international) based on cognitive beahvioural therapy and mindfulness therapy for Parkinson’s disease patients and their carers. Dr Dissanayaka is the first author of the top cited publication for “Anxiety in Parkinson’s disease” for the past 10 years (Scopus), is an author of a book chapter titled “Anxiety in Parkinson’s disease” in “Anxiety in Older People: Clinical and Research Perspectives” (Cambridge Press), and is a lead collaborator of the international working group focused on anxiety in Parkinson’s disease research. Despite part-time (0.6FTE) work, Dr Dissanayaka’s publications record over the past 8 years places her in the top 10% of the Senior Lecturers in the relevant field of Psychology according to the Go8 Universities productivity and citations. For the past 5 years, her publications are cited (Field Weighted Citation Impact) 2.14 than the average citation rate in the field of Psychology, 1.94 in Medicine and 1.91 in Neuroscience. 81% of her publications are published in journals ranked in the top quartile (SciVal March 2018).

Grants and Awards: Dr Dissanayaka has received continuous funding via 3 competitive fellowships (including NHMRC), 16 competitive research grants (91% lead investigator). Her grant record includes international awards such as the prestigious NARSAD young investigator international award 2018 received from the United States Brain & Behaviour Research Foundation, and 5 travel awards. She is also a recipient of 2 Outstanding Young Researcher Awards in 2013 and 2015.

Supervision: Dr Dissanayaka holds an outstanding record of supervision in disciplines of Psychology, Medicine, Biomedical Sciences, and Pharmacy, and has supervised 62 students, 2 postdocs and 7 Research assistants. For the past 5 years, under her primary supervision, 10 students completed research thesis (4 DPsyc, 2 MPsyc and 4 Honours). Dr Dissanayaka’s supervision extends to Psychology Advanced Trainee interns who are provisionally registered psychologists with the Australian Health Practitioner Regulation Agency (Psychology Board of Australia). She has supervised 27 Psychology trainee interns, who are the next generation of psychology service providers in Australia and worldwide (e.g. Singapore, Malaysia).

Community Engagement and Professional Involvement: Dr Dissanayaka is an author of >90 conference abstracts (43 international and 27 published), >50 invited seminars, and >15 media reports. She is an advocate for the Lions Medical Research Foundation, Royal Brisbane & Woman's Hospital Foundation, and Parkinson’s Queensland Incorporated, and has presented many public seminars throughout Queensland. Dr Dissanayaka is an active member of the University of Queensland, Faculty of Medicine, Low and Negligible Risk Ethics Committee, UQ Centre for Clinical Research Career Development and Innovation Group, NHMRC National Institute for Dementia Research, Australian Cognitive Neurosciences Society, Movement Disorders Society of Australia and New Zealand, and International Movement Disorders Society. She is a peer reviewer for >20 international journals and an external grant reviewer for NHMRC and Parkinson's UK.
