A scientific strategy that explores therapeutic targets based on the biology of aging is gaining ground as an effective approach to prevent and treat Alzheimer's disease. [...]
Researchers from the University of Waterloo found that even if people weren't good at it, drawing, as a method to help retain new information, was better than re-writing notes, visualization exer [...]
A research team has identified genetic processes involved in the neurodegeneration that occurs in dementia -- an important step on the path toward developing therapies that could slow or halt the cour [...]
Researchers report that 27 percent of people 65 and older own one or more firearms, and 37 percent live in a home with a firearm present. One study of patients with dementia or related mental health i [...]
Scientists have identified gene recombination in neurons that produces thousands of new gene variants within Alzheimer's disease brains. The study reveals for the first time how the Alzheimer [...]
To turn back the clock on Alzheimer's disease, many researchers are seeking ways to effectively diagnose the neurodegenerative disorder earlier. One potential way to do this is by tracking a pers [...]
Doctors may one day be able to gauge a patient's risk of dementia with an MRI scan, according to a new study. Using a new technique for analyzing MRI data, researchers were able to predict who wo [...]
Artificial intelligence (AI) technology improves the ability of brain imaging to predict Alzheimer's disease, according to a new study.

A new study suggests drinking coffee may protect you against developing both Alzheimer's and Parkinson's disease. [...]
A research team decided to explore whether exercise could reduce the risk of falling among community-dwelling people with Alzheimer's Disease who also had neuropsychiatric symptoms. [...]
Forgetfulness and age-related memory lapses are a common complaint among older adults, but what is still not understood is what causes these changes. Recent research brings us a step closer to uncover [...]
Herpes is the dreaded 'gift that keeps on giving'. But could it also be taking our memories? Decades of research show a striking correlation between Alzheimer's disease risk and infecti

Pre-eclampsia is associated with an increased risk of later dementia, particularly vascular dementia, caused by reduced blood supply to the brain due to diseased blood vessels, finds a large study. [...]
Stiffness of the aorta -- more so than blood pressure or subclinical brain disease -- is a key risk factor for dementia. Since aortic stiffness can be reduced by medication and healthy lifestyle chang [...]
Only a small proportion of cases of dementia are thought to be inherited -- the cause of the vast majority is unknown. Now a team of scientists believe they may have found an explanation: spontaneous [...]
New research has revealed a role for splicing proteins in the pathology of Alzheimer's disease. Increased phosphorylation of the SRRM2 protein, seen in AD mouse models and human patients, was fou [...]
A 2016 study showed that exposure to urban pollution involving magnetite particles played a role in the development of Alzheimer's disease. It began from the hypothesis that magnetite particles w [...]
People with a particular kind of irregular heartbeat called atrial fibrillation may experience a faster decline in thinking and memory skills and have a greater risk of dementia than those without atr [...]
In preparation for more tools that detect and measure the biology associated with Alzheimer's and other dementias earlier and with more accuracy, experts have published appropriate use criteria ( [...]
A team of scientists has successfully trained a new artificial intelligence (AI) algorithm to make accurate predictions regarding cognitive decline leading to Alzheimer's disease. [...]
A new study has shown that by combining imaging and neuropsychological testing, one can more accurately assess the cognitive status of individuals. [...]
Long-term exposure to periodontal disease bacteria causes inflammation and degeneration of brain neurons in mice that is similar to the effects of Alzheimer's disease in humans. Periodontal disea

The first large US study of cognition in older breast cancer patients found that within the first two years after diagnosis and treatment, most women do not experience cancer-related cognitive problem [...]
Up to half of people with Alzheimer's disease (AD) use a psychotropic drug, and one in five uses two or more psychotropics concomitantly, according to a new study. [...]
A newly identified mechanism explaining the possible cause for Alzheimer's and traumatic brain injury may have also led to the discovery of an effective treatment.

Leaks in the blood-brain barrier can provide early detection for Alzheimer's and diseases. [...]
Nilvadipine shows no benefit for the treatment of Alzheimer's disease in mild and moderate stages of the disease, but further studies targeting the early phase of the disease may be warranted. [...]
Researchers learn more about the relationship between sexual behavior, function, and cognition (people's ability to think and make decisions). [...]
A vicious feedback loop underlying brain degeneration in Alzheimer's disease may explain why so many drug trials have failed, according to researchers. Their study also identifies a clinically ap [...]
Zombie cells are the ones that can't die but are equally unable to perform the functions of a normal cell. These zombie, or senescent, cells are implicated in a number of age-related diseases. Re
