Protein tangles have been blamed for causing Alzheimer's – but drugs that target them keep failing.
Not all drug development needs to start from scratch. Sometimes researchers discover that a drug developed for one disease can be used for another. Here a cancer drug may show promise for dementia.
Nuts are a healthy part of any diet, but can they really make you smarter?
Our ability to smell is a function of the brain, so it makes sense that an impaired sense of smell can point to cognitive decline. The good news is training our noses may be effective.
Antipsychotic drugs are often used to "chemically restrain" aged care residents and control their behaviour. The system needs to change – but lessons from the US tell us it's not going to be easy.
Many pieces leading to Alzheimer's disease have been identified. To put the pieces together, one scholar argues that the government should launch a Manhattan Project-scale effort to find a cure.
We were the first to make the connection between P. gingivalis and fully diagnosed Alzheimer’s disease. While evidence of a link is growing, it must be interpreted in context.
Research is revealing many ways in which we can reduce our dementia risks -- from eating a Mediterranean diet and exercising, to playing games and studying for degrees.
Research milestones in the study of memory may help us find solutions to memory disorders like Alzheimer's or recovery from brain trauma.
As you age, your body deteriorates and your risk of disease and injury increases. Here's a decade by decade guide to what you're up against – and what you can do about it.
Air pollution is bad for our heart and lung health – and a new study says it may be bad for brain health, too.
A new study suggests that being intellectually engaged does nothing to slow cognitive decline, but it does start the decline from a higher point.
November is National Family Caregivers Month; did they get your attention? If not, you are not alone. Family caregivers are overlooked by the health care system, and they are burning out. Here's why.
People with Down syndrome are at much higher risk of dementia than the general population. Knowing when cognitive changes start is critical for developing new drugs.
A simple method could vastly improve the quality of life of those with dementia.
From aggressive patients with Alzheimer's to frustrated caregivers, dementia is increasingly entwined with violence in private homes and residential facilities.
Higher education for seniors shows promise – for combatting social isolation, increasing well-being and delaying the onset, or slowing the progression, of dementia.
New review finds that over 150 papers strongly support the view that herpes simplex plays a role in Alzheimer’s disease.
With an ageing population, dementia is becoming more and more prevalent. But what does dementia actually do to the brain to cause changes in behaviour?
Media pioneer Ted Turner's announcement that he has Lewy body dementia brings the illness into the spotlight, which is rare. A neurologist explains why it's hard to even get a correct diagnosis.
