Dementia study reveals difference in rates between sexes

It’s well known that dementia affects everyone differently, and new research has explored how sex comes into play.

A team from the University of Queensland (UQ) and Florey Institute of Neuroscience and Mental Health said there could be underlying biological factors driving the different rates of Alzheimer’s and vascular dementia among men and women.

For their study, the researchers examined 1.1 million Australian death certificates for any mention of dementia, looking out for where it was listed either as the cause of death or as an underlying cause.

They found that within those 184,562 certificates, women had a 14 per cent higher rate of death from Alzheimer’s disease while men had a 20 per cent higher rate of death from vascular dementia.

UQ health biostatistician Dr Michael Waller said possible biological factors driving the difference in rates include hormonal changes, particularly during menopause, and even differential risk for other conditions such as cardiovascular disease.

“There’s a real need to look at the whole picture when studying how a disease like dementia affects a population,” Waller said.

“Regardless of the gender differences, society needs to consider the implications of people living longer and more people developing dementia.”
