A study which began in 1946 is unlocking new clues to dementia.

Ruth Itzhaki has spent more than 30 years researching whether certain common viruses play a role in the development of Alzheimer’s. But for years her research was greeted with hostility.

Just months after the end of the second world war, the longest running study of health over the human life course in the world began – and it’s still going.
Missing person calls involving an individual with dementia increased by between 10 and 50 per cent across all Ontario regions over the last five years.
With an increasing number of people living with dementia worldwide and in Canada, it’s crucial to find ways to promote community awareness and prevent people with dementia from getting lost.
Uncharted Brain: Decoding Dementia is a new podcast series from The Conversation.
A podcast and long read series exploring new research into the brain and dementia.

Too much amyloid-beta in the brain has long been considered the cause of Alzheimer’s. New research suggests it might be the opposite.

Lecanemab, an experimental dementia drug, slowed cognitive decline by 27% in late-stage clinical trials.

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.
