A team of scientists spent six months co-designing robots with informal caregivers for people with dementia, such as family members. They found that caregivers wanted the robots to fulfill two major roles: support positive moments shared by caregivers and their loved ones; and lessen caregivers’ emotional stress by taking on difficult tasks, such as answering repeated questions and restricting unhealthy food.

Having a parent with Alzheimer’s disease has been known to raise a person’s risk of developing the disease, but new research suggests that having second- and third-degree relatives who have had Alzheimer’s may also increase risk. The study is published in the March 13, 2019, online issue of Neurology®, the medical journal of the American Academy of Neurology.

Scientists continue to find evidence linking Type 2 diabetes with Alzheimer’s disease, the most common form of dementia and the seventh leading cause of death in the United States. However, little is understood about the mechanism by which the two are connected.Now, researchers at Joslin Diabetes Center, an affiliate of Harvard Medical School, have demonstrated that impaired insulin signaling in the brain negatively affects cognition, mood and metabolism, all components of Alzheimer’s Disease.

In a study of older people with no clinical diagnosis or signs of dementia when hospitalized to repair hip fractures, Johns Hopkins researchers say they found biomarkers of Alzheimer’s disease in most of the patients’ spinal fluid samples. The researchers say results of their study add to evidence that brain alterations that lead to poor balance in older people may underpin both increased risk of hip-fracturing falls and Alzheimer’s disease, and that hip fracture itself may therefore serve as a first sign of undiagnosed disease.

Bacteria in the gut do far more than help digest food in the stomachs of their hosts, they can also tell the genes in their mammalian hosts what to do. A study published today in Cell describes a form of “interspecies communication” in which bacteria secrete a specific molecule—nitric oxide—that allows them to communicate with and control their hosts’ DNA, and suggests that the conversation between the two may broadly influence human health.

A new study has found that transplanting the bone marrow of young laboratory mice into old mice prevented cognitive decline in the old mice, preserving their memory and learning abilities. The findings support an emerging model that attributes cognitive decline, in part, to aging of blood cells, which are produced in bone marrow.

Previous studies have suggested that having a higher level of education may protect the brain to some extent against dementia, providing a “cognitive reserve” that buffers against the disease. But results have been mixed, and a new study finds that education does not play a role in when the disease starts or how fast it progresses. The study was published in the February 6, 2019, online issue of Neurology®, the medical journal of the American Academy of Neurology.
