Dementia and the distinct patterns of brain disorganisation

Researchers from the University of California, San Francisco have reviewed findings from an emerging area of brain imaging research, called ‘resting-state’ imaging, and report in the Journal, Biological Psychiatry, that distinct brain networks are associated with different types of dementia.

What is resting-state imaging?

Do the eyes have it? Retinal photography to screen for dementia

Researchers working on the Australian Imaging, Biomarkers and Lifestyle (AIBL) Flagship Study of Ageing have found that changes in the structure of blood vessels in the retina may be related to early signs of Alzheimer’s disease.

Writing in the journal Translational Psychiatry earlier this year, the AIBL research team reported the results of a novel study that for the first time has linked retinal blood vessel changes with Alzheimer’s disease.

Cognitive training and dementia

Brain training is often promoted as a way of reducing the risk of dementia, and there is no question that a lifetime of stimulating and engaging mental activity can help to reduce (although unfortunately not eliminate) the risk of developing dementia.

However, less is know about whether cognitive training programs and interventions can help people with early to moderate dementia to slow the progression of the disease, or even to regain some of their mental function.

Rats - a promising animal model for Alzheimer's disease

Genetically modified mice have been the mainstay when it comes to Alzheimer’s disease research, but Dr. Terrence Town and his colleagues from Los Angeles suggest instead we should be looking at rats.

A study to prick up your ears: hearing loss associated with cognitive decline

Those experiencing hearing loss in later life may be at a higher risk of developing dementia, according to new research published in the JAMA Internal Medicine.

Dr Frank Lin and his colleagues from the John Hopkins Centre on Aging and Health in the USA investigated whether hearing loss is independently associated with accelerated cognitive decline.
