Eating healthy foods doesn’t just improve our physical health. It can benefit our mental health, too.
Many chronic diseases increase our risk of Alzheimer's disease. This link between our bodies and our brains means certain healthy choices could protect our cognitive function.
An enzyme called TOR could hold the secret to a longer, healthier life.
Living near green spaces is associated with better cognition.
Some previous research suggests people living in rural areas may be at a higher risk of developing Alzheimer’s disease. But these results tell a different story.
People with Alzheimer's disease have lower rates of type 2 diabetes than the general population.
Older people often take many supplements, including ones purported to help with brain health. A recent study says the supplements do not work.
With fear of a diagnosis of Alzheimer's a constant concern for many seniors, they turn to supplements. A recent study suggests they'd be better off keeping their money.
In most cases, scientists are still unsure of what causes Alzheimer’s disease.

After the failure of multiple drug trials the outlook for an Alzheimer's drug is bleak. This shouldn't be a surprise. We don't know the cause or even how to diagnose the disease.
Protein tangles have been blamed for causing Alzheimer's – but drugs that target them keep failing.

Not all drug development needs to start from scratch. Sometimes researchers discover that a drug developed for one disease can be used for another. Here a cancer drug may show promise for dementia.
As people age, their sense of smell can decline.
Our ability to smell is a function of the brain, so it makes sense that an impaired sense of smell can point to cognitive decline. The good news is training our noses may be effective.
Signals from inside the brain can reveal what’s happening in nerve cells.
When nerve cells in the brain pass electrical signals to each other, they create tiny electric fields that can be sensed from outside the skull.
Figuring out the pieces to the Alzheimer’s puzzle.
Many pieces leading to Alzheimer's disease have been identified. To put the pieces together, one scholar argues that the government should launch a Manhattan Project-scale effort to find a cure.
We were the first to make the connection between P. gingivalis and fully diagnosed Alzheimer’s disease. While evidence of a link is growing, it must be interpreted in context.
If you engage in cognitively stimulating activities in midlife, such as reading and playing games, you can reduce dementia risk by about 26 per cent, according to research.
Research is revealing many ways in which we can reduce our dementia risks -- from eating a Mediterranean diet and exercising, to playing games and studying for degrees.
Understanding how and where memory functions in the brain can lead to discoveries in treating memory disorders.
Research milestones in the study of memory may help us find solutions to memory disorders like Alzheimer's or recovery from brain trauma.
Long-term exposure to air pollution was linked to cognitive decline in elderly people.
Air pollution is bad for our heart and lung health – and a new study says it may be bad for brain health, too.
Studying digital and biological connections can shed light on both fields.
Biological research can inspire technological innovation. Also, software that models computer networks can inform health care for patients with neurological disorders.
Researchers studying Alzheimer’s disease use fetal tissue for their experiments.
The Trump administration has banned NIH researchers from using fetal tissue. The tissue is an essential tool for scientists investigating diseases ranging from Alzheimer's to Zika virus infections.
Alzheimer’s disease is the most common form of dementia.
People with Down syndrome are at much higher risk of dementia than the general population. Knowing when cognitive changes start is critical for developing new drugs.
Researchers are developing treatments for blindness caused by neurodegeneration.

A new type of drug blocks the destruction of neurons in the eye, preventing blindness. The researchers hope that the same therapy can be applied to other common neurodegenerative diseases.
Dementia patients are often the perpetrators and often the victims of abuse. Research also shows that a medical history of head injury can more than double the risk of developing Alzheimer’s disease in some populations, even after many years.
From aggressive patients with Alzheimer's to frustrated caregivers, dementia is increasingly entwined with violence in private homes and residential facilities.
