Research shows age plays limited role in cognitive decline

Cognitive decline is among the most feared aspects of growing old, yet new research suggests that ‘senior moments’ play less of a part in the normal ageing process than once thought.

Could lack of an essential amino acid cause Alzheimer’s disease?

What causes Alzheimer’s disease? This question doesn’t have a simple answer but is one that researchers from Duke University, USA are one step closer to understanding. They have identified a mechanism behind neuronal dysfunction, which they believe could play a major role in Alzheimer’s disease symptoms.

Development of a speech based system for the early detection of Alzheimer’s disease

Researchers from Spain have developed a speech based technology system which could potentially analyse and detect the early signs of Alzheimer’s disease.

New ultrasound scanning technique removes amyloid beta plaques in mouse brains

World class research out of the University of Queensland has shown that an ultrasound scanning technique can reduce and remove amyloid beta plaques from the brains of mice with Alzheimer’s disease.

How do you define a head trauma? Researchers seek clearer definition

A recent Nature article highlighted the need for special guidelines to be developed to assist in the diagnosis of brain disorders in retired American footballers.

Mounting evidence indicates that repeated head injuries may be linked to degenerative brain disorder later in life. In light of this, neuroscientists recently met at Boston University to examine the characteristics of Chronic Traumatic Encephalopathy (CTE), a form of dementia first diagnosed in professional boxers and commonly seen among other professional contact sports players.

A simple skin test could detect Alzheimer’s disease

New research out of Mexico has added another potential diagnostic test to the mix, suggesting a simple skin test can detect abnormal levels of Tau protein before symptoms of Alzheimer’s disease appear.

Another ‘PART’ of the dementia puzzle gives hope to targeting treatments

Researchers in America have proposed a new category of brain disease, called ‘Primary Age-Related Tauopathy’ (or PART), to describe people who have dementia and display many of the characteristic symptoms of Alzheimer’s disease, but who do not have significant levels of amyloid beta plaque in their brains.

Professor Peter Nelson from the University of Kentucky's Sanders-Brown Center on Aging was lead researcher on a study published recently in the Journal Acta Neuropatholigica. He explained the importance of these new findings, saying:

New Australian research progresses the development of an Alzheimer’s disease blood test

Progress towards a simple blood test that could diagnose Alzheimer’s disease 10-20 years before symptoms occur has been made, with the results of a new study by Australian researchers from the University of Melbourne.

This research, published today in the Journal Molecular Psychiatry, was partially supported by an 2013 Alzheimer’s Australia Dementia Research Foundation project grant awarded to Dr Lesley Cheng (pictured).
