Early symptoms of gum disease include red, swollen gums, and bleeding when you brush or floss your teeth.

Here’s why it’s so important to look after your oral health.
New study finds that middle-aged people who had nightmares every week, are four times more likely to experience cognitive decline.
A new study predicts a significant increase in the number of Canadians living with dementia over the next three decades.
Action is needed to hold off a wave of dementia cases in an aging population. One of the most effective tools to reduce the prevalence of dementia is to address modifiable factors.

Alzheimer’s may not be primarily a disease of the brain. It may be a disorder of the immune system within the brain. Beta-amyloid may not be an abnormal protein, but part of the brain’s immune system.
A thinning of the retina is associated with earlier ageing of the brain. Widely available retinal imaging could help detect cognitive decline in its earliest stages.

Nonhuman primates like rhesus monkeys share certain characteristics with people that may make them better study subjects than mice for research on neurodegenerative diseases.
You may dismiss many behaviour changes as just a normal part of ageing. But it may be doggy dementia, or canine cognitive dysfunction.
What we eat matters, and having just the right amount of essential nutrients is key to our overall health.

Diets high in fat, sugar and processed foods are associated with higher calorie intake, poorer memory and lower cognitive function.
A highly cited paper on Alzheimer’s disease may have been purposely manipulated.
Drugs can convert between different isomers in the body, leading to unexpected effects.

From thalidomide to resveratrol, molecules with the exact same chemical properties can have drastically different effects in the body depending on how they’re arranged in space.

Not all Alzheimer’s research has been compromised by allegations of scientific fraud. But we should interrogate whether the governing bodies of research and drug approvals are truly effective.
Communities that are underrepresented in research may also be at increased risk for dementia, or tend to experience dementia differently, often with poorer quality of care, later diagnoses and at possibly higher rates than the general population.
Much dementia research does not reflect ethnically diverse communities. Studies used to make policy, clinical and investment decisions in dementia should reflect the diverse Canadian population.
Noradrenergic drugs were shown to improve some brain function and feelings of apathy.

Noradrenergic drugs are already used to treat a variety of conditions, including ADHD and depression.
Stereotypes and common misconceptions about dementia often emerge in the metaphors used to explain and understand it.
Because they help to create a shared understanding, metaphors can play a critical role in navigating the gap between the knowledge patients and health-care providers bring.
It hasn’t been known until now to what extent your night’s sleep affects short-term dementia symptoms.
Participants who woke up fewer times during the night performed better on memory tasks the next day.
It is possible to grow cells from a skin sample in a Petri dish and transform them into neurons in about a month.
Cell cultures have shown promise in representing diseases. The Petri dish is not as different from a sick person as one might think.

Long overlooked by scientists, white matter may provide clues to some of the brain’s greatest mysteries.

Although Medicare has agreed to pay for Aduhelm, its coverage comes with restrictions.
As the population of American Indian and Alaska Native adults ages, the risk for Alzheimer’s disease and other dementias – along with various chronic conditions – goes up.

A clearer understanding of the true treatment costs of dementia for American Indian and Alaska Native adults could help health services better meet the needs of the populations they serve.
Older adults who nap at least once for more than an hour a day have a 40% higher chance of developing dementia.

While longer naps are a normal part of aging, excessively long dozes could be a warning signal for cognitive decline.
