Sensory decline and future risk of dementia: An update

Presenter: A/Prof Hamid Sohrabi, Murdoch University

About the presentation

Sensory changes are very common and when reported by older adults are not always benign. Sensory decline could be a preclinical marker for a wide range of psychiatric or neurological conditions. For example, age related decline in olfaction (anosmia) has been reported as a diagnostic and screening marker for dementia. It has been reported in Parkinson disease as well as depression and schizophrenia. Furthermore, age-related hearing loss (presbycusis) has been reported as an indicator of dementia. However, it also is a major modifiable risk factor that can be successfully treated or managed. In this presentation, I will discuss our research on age-related hearing loss and olfactory dysfunction and the current understanding of how these sensory changes may hint future risk of dementia.  

About the presenter

Hamid Sohrabi is an Associate Professor of clinical Neurosciences and Psychology and the Director of the Centre for Healthy Ageing at Murdoch University. He leads the Western Australia Memory Study, a longitudinal study into the neuropsychological and biological markers of dementia due to Alzheimer’s disease started in 1996. Hamid has published over 90 papers in the last 10 years and is involved in several large-scale national and international studies on dementia prevention and treatment. His research seeks to translate knowledge obtained from clinical and cognitive neurosciences into screening and diagnostic measures for pre-clinical and prodromal stages of Alzheimer’s disease as well as preventive interventions to halt pathological cognitive decline and dementia. Specifically, he is interested in sensory impairment both as a marker of ageing and neurodegeneration and as a potential path for interventions that can improve quality of life.
