The tiny air pollutants known as PM2.5, emitted by vehicles, factories and power plants, aren’t just a hazard for lungs. A study finds more brain shrinkage in older women exposed to pollution.
Our stomach and brain are connected through the ‘gut-brain axis’.

In the time of coronavirus, people with dementia and their caregivers need more support than ever.

New statistics show that people with dementia have been particularly vulnerable during the pandemic.
Around 50m people worldwide are living with dementia.
Architects need to learn to see dementia not as a disease but as a disability, and shift the design focus to spaces that can help maintain the everyday functions of people with the condition.
More than half of patients with dementia also suffer from depression. If the depression remains untreated, the associated memory and cognitive problems worsen. Conversely, a significant history of depression seems to be a risk factor for dementia.
Dementia and depression are two diagnoses that rob older adults of health and happiness. Despite their obvious differences, it is becoming ever more apparent that the two conditions are connected.
Even drinking fewer than 14 units of alcohol a week was damaging.
Drinking at "safe" levels was shown to reduce the amount of a person's total brain tissue.
Your medical team should determine whether you have dementia or just normal memory loss due to aging.

September is Alzheimer's Awareness Month and therefore a good time to talk about dementia. Alzheimer's is the most common dementia, but there are others to be aware of, a gerontologist explains.
More and more studies are revealing the cognitive effects of COVID-19.

Many patients suffering from COVID-19 exhibit neurological symptoms, from loss of smell to delirium to a higher risk of stroke. Down the road, will COVID-19 survivors face a wave of cognitive issues?
In healthy older people, loneliness has a pattern of stress response similar to that of people who are under chronic stress.

The social isolation older adults are experiencing as they try to stay safe from the coronavirus pandemic is raising new mental health risks, but people can take steps to protect themselves.

A blood test to detect Alzheimer's disease in people who have symptoms and even those who don't has been shown to work. Scientists still need to improve its accuracy rate to almost 100%, however.
The study investigated what role oxytocin had in memory.

Though a recent study's results were promising, there is still much that researchers don't know.
Many of these risk factors are preventable.
Stress, depression, and high blood pressure were just some of the risk factors the study's researchers identified.
Our method could someday potentially detect the disease before it starts developing in a person’s brain.

Having extra copies of a gene called BACE2 can slow down the development of Alzheimer's disease in human brain cells.

The Federal Bureau of Prisons recently opened a unit for people suffering dementia. But is incarceration a 'cruel and unusual' punishment for those who don't understand why they are behind bars?

What do you do when the subject is a disease as much as a person, and when the disease then subsumes the person – to the point where he can't recognize his own son?
People who worried or ruminated more often had biological markers of Alzheimer’s disease in their brain.

Our study found that people who had higher repetitive negative thinking patterns experienced more cognitive decline over a four-year period.
This antibody could be used to develop future treatments.

Between 10-15% of all cells within the brain are microglia.
Tiny parts of our genome once thought useless are being turned into ways to diagnose and treat disease.
Flavonoids are a group of compounds found in almost every fruit and vegetable.
Foods rich in flavonoids (such as apples, berries, or tea) are important for cognitive health, research suggests.
