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.
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.
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.
