Poor spatial navigation could predict Alzheimer’s disease years before the onset of symptoms

People at risk of Alzheimer’s disease have impaired spatial navigation prior to problems with other cognitive functions, including memory, finds a new study led by UCL researchers. The research, published in Alzheimer’s & Dementia: The Journal of the Alzheimer’s Association, used virtual reality to test the spatial navigation of 100 asymptomatic midlife adults, aged 43-66, … Read more

How AI can help spot early risk factors for Alzheimer’s disease

UC San Francisco scientists have found a way to predict Alzheimer’s Disease up to seven years before symptoms appear by analyzing patient records with machine learning. The conditions that most influenced prediction of Alzheimer’s were high cholesterol and, for women, the bone-weakening disease osteoporosis. The work demonstrates the promise of using artificial intelligence (AI) to … Read more

Air pollution linked to more signs of Alzheimer’s in brain

People with higher exposure to traffic-related air pollution were more likely to have high amounts of amyloid plaques in their brains associated with Alzheimer’s disease after death, according to a study published in the February 21, 2024, online issue of Neurology®, the medical journal of the American Academy of Neurology. Researchers looked at fine particulate … Read more

Protein accumulation on fat droplets implicated in late-onset Alzheimer’s disease

UNC School of Medicine researcher Sarah Cohen, PhD, and Ian Windham, a former PhD student from the Cohen lab, have made a new discovery about apolipoprotein E (APOE) — the biggest genetic risk factor for late-onset Alzheimer’s disease. Older people who inherited a genetic variant called APOE4 from their parents have a two- or three-times … Read more

Language barriers could contribute to higher aggression in people with dementia

Immigrants living with dementia were more likely to present with agitation and aggression compared with their non-immigrant counterparts, a new study by Edith Cowan University (ECU) in collaboration with The Dementia Centre, HammondCare, found. Researchers from ECU’s Centre for Research in Aged Care and HammondCare’s The Dementia Centre noted that behaviours and psychological symptoms of … Read more

Scientists discover a potential way to repair synapses damaged in Alzheimer’s disease

While newly approved drugs for Alzheimer’s show some promise for slowing the memory-robbing disease, the current treatments fall far short of being effective at regaining memory. What is needed are more treatment options targeted to restore memory, said Buck Assistant Professor Tara Tracy, PhD, the senior author of a study that proposes an alternate strategy … Read more

Re-energizing mitochondria to treat Alzheimer’s disease

Nerve cells in the brain demand an enormous amount of energy to survive and maintain their connections for communicating with other nerve cells. In Alzheimer’s disease, the ability to make energy is compromised, and the connections between nerve cells (called synapses) eventually come apart and wither, causing new memories to fade and fail. A Scripps … Read more

New tool helps predict progression of Alzheimer’s

About 55 million people worldwide are living with dementia, according to the World Health Organization. The most common form is Alzheimer’s disease, an incurable condition that causes brain function to deteriorate. In addition to its physical effects, Alzheimer’s causes psychological, social and economic ramifications not only for the people living with the disease, but also … Read more
