Physical activity can help protect the brain as we age.

People who were more active had lower levels of inflammation in their brain.
Does too much sleep really increase your risk of cognitive decline?
The researchers found that people who slept less than 4.5 hours and more than 6.5 hours every night had a greater risk of cognitive decline.
Our research suggests the multiplication of protein aggregates in individual regions of the brain, rather than their spread between regions, is key to the progression of Alzheimer’s disease.
PET scans using a special tracer can pick up ‘tau tangles’ in the brain.
Vocabulary surrounding Alzheimer’s and other related disorders must be carefully chosen. Here, sculpture by Jaume Plensa, in Montréal.
Arts-related activities for people living with Alzheimer’s and other related disorders could improve people’s quality of life, but collaborating in communities requires a common language.

To stay healthy, it’s important to understand how wildfire smoke can harm your body and how to protect yourself.
Aducanumab (Aduhelm) was approved in the U.S., but there is no convincing evidence the drug will help Alzheimer’s patients.
FDA approval of aducanumab (Aduhelm) was contentious. Its submission to Health Canada for approval highlights concerns about evidence, independence and transparency in Canada’s drug approval process.
There are different types of memory and not all of them are related to Alzheimer’s disease.
Alzheimer’s disease is often associated with a decline in episodic memory. Patients will complain that they can’t remember events they’ve experienced, conversations they’ve had, things they’ve done.
Alzheimer’s, like many diseases, has a genetic component.

Using a technique called admixture mapping, researchers can leverage the diversity of people with mixed ancestry to look for hard-to-find genetic risk factors for diseases like Alzheimer’s disease.
Ubiquitin tags in cells serve different functions depending on stress conditions.
Insight on how a unique protein plays a role in cellular stress responses may provide more clues on how to treat diseases like ALS and Alzheimer’s.
Clinical trials of the drug have shown mixed results.
Alzheimer’s disease is characterized by progressive memory loss, spatial disorientation and many other cognitive and behavioural disorders that ultimately lead to a state of total dependence.
The new drug is based on the idea that a build-up of amyloid in the brain leads to the disease. But that hypothesis has been under scrutiny lately.
More research is needed to prove the drug slows cognitive decline.

The first drug targeting Alzheimer’s disease has been approved in 20 years – but its approval isn’t based on substantial evidence.
Do the benefits of approving a drug before confirming it works outweigh the potential costs?

The FDA approved Alzheimer’s disease drug aducanumab despite minimal evidence of its efficacy. Whether this decision ultimately hurts or helps patients depends on data researchers don’t yet have.
Isolation and segregation create and reinforce another kind of barrier to those with dementia: stigma.
‘Dementia friendly’ communities seek to support people with memory loss, recognize them as equals, celebrate their contributions and enable them to live with purpose in welcoming communities.
The colors in this microscope photo of a fruit fly brain show different types of neurons and the cells that surround them in the brain.

Adaptable neurons are tied to learning and memory but also to neurological disorders. By studying fruit flies, researchers found a mechanism that controls neuroplasticity.

A neuroscientist and a clinician watched two new films about dementia. They recognised what they saw.
The equivalent of one bacon rasher was associated with 44% increased dementia risk.
If so, it’s just one lifestyle risk among many others.
