Researchers are currently investigating a number of aspects of dementia. Research into the causes of dementia There is still much to learn about the possible causes of dementia, including Alzheimer's disease - the most common form of dementia. Research into better ways of diagnosing dementia Developing better and more accurate methods of diagnosis is an important research focus. Currently there is no single test that can accurately diagnose dementia. Dementia care research Research into quality dementia care and the best ways of supporting carers provides important insights into improving quality of life of people with dementia, their families and carers. Research into dementia treatments and cure There is currently no medication that modifies or slows the progression of Alzheimer’s disease or other kinds of dementia. Available medications may reduce symptoms and improve quality of life in some people, but they do not stop the progress of the disease. Dementia risk reduction and prevention research There is good evidence for dementia risk reduction through changed lifestyle and behaviours but the evidence base needs to be further developed and the interaction between lifestyle and genetic factors better understood.
