Associate Professor of Geriatric Psychiatry

Honorary Professor of Psychiatry
University of Manchester
Professional Profile
Key areas: Dementia, neuropsychiatry of neurodegenerative movement disorders (including Parkinson’s disease), global brain health, pragmatic clinical trials in dementia

It is our great privilege to be part of this remarkable mission of working together for global brain health. Brain health is a right, not a privilege.

Iracema is an Associate Professor in geriatric psychiatry at Trinity College Dublin and a Consultant Psychiatrist in St. James’s Hospital, Dublin. She brings to GBHI clinical and research experience in dementia and older adult psychiatry, particularly the neuropsychiatry of neurodegenerative movement disorders such as Parkinson’s disease. Iracema developed and led the Greater Manchester clinical trials’ program for dementia for several years as principal investigator. She is the Chief Investigator for EU-funded SENSE-Cog (, a five-year comprehensive research program involving 7 countries and 27 investigators. The aim of SENSE-Cog is to understand the links among hearing, vision and cognitive impairment in older people. One of SENSE-Cog’s projects is a trans-national RCT investigating whether hearing and vision enhancement improves outcomes for people with dementia. Additionally, Iracema recently completed the world’s largest RCT of a non-pharmacological intervention (Cognitive Stimulation Therapy adapted for PD; PD-CST) for people with Lewy body dementias (LBDs; the INVEST project). She is also building collaborations for dementia research in Bangladesh, Pakistan and India and is leading the ‘Research Roadmap for Dementia in Pakistan’ project, which is model for lower and middle-income countries (LMIC).

At GBHI, Iracema aims to develop closer ties with dementia programs in LMICs, particularly South Asia, with a focus on capacity and capability building for pragmatic, clinically meaningful dementia research. In Ireland, she also hopes to build collaborations for clinical research for the LBDs through a follow-on study of the INVEST program. Iracema’s clinical work is based at the Mercer’s Institute for Successful Ageing in St James’s Hospital, where she works in the Memory Assessment Service. She intends to help expand services for people with complex forms of dementia, such as young onset dementia and the LBDs.

Bio: Iracema undertook her basic medical and psychiatric training at the University of British Columbia, Canada, followed by a fellowship in the neuropsychiatry of neurodegenerative disorders at the Johns Hopkins School of Medicine. She joined the faculty at Hopkins before moving to the UK in 2002. She undertook her doctorate (Neural Correlates of Disorders of Reward and Motivation in Parkinson’s disease) before taking up the post of Professor of Psychiatry in Ageing and Dementia at the University of Manchester. She moved to Dublin in 2019.
