How does learning by yourself compare with instruction when it comes to preserving brain function? Elizabeth Tracey reports Feb 23, 2026

Show notes

When you have to teach yourself a task and adapt to having that task speed up, that’s one type of learning used in a study assessing different types of brain training and development of Alzheimer’s disease. Marilyn Albert, study author …

Does having to figure things out on your own protect your brain better than other kinds of activities? Elizabeth Tracey reports Feb 23, 2026

Show notes

People who received memory and reasoning training or those who didn’t receive any brain training were more likely to be diagnosed with Alzheimer’s disease twenty years down the road than those who did cognitive speed training, which required them to …

What exactly is cognitive speed training? Elizabeth Tracey reports Feb 23, 2026

Show notes

Among a cohort of 2800 people, those who received cognitive speed training compared to usual care or memory and reasoning training we less likely to be diagnosed with Alzheimer’s disease 20 years later. That’s according to a study by Johns …

What does 20 years of follow up tell us about activities to protect the brain? Elizabeth Tracey reports Feb 23, 2026

Show notes

Cognitive speed training, where a computer is used to present an image and require tasks based on images that speeds up, resulted in fewer dementia diagnoses than other types of cognitive training, a study of more than 2800 adults over …

Is it possible to make personal changes to stave off dementia and preserve independence? Elizabeth Tracey reports Feb 23, 2026

Show notes

Showing someone a visual task on a computer and then speeding things up so they must complete it faster and faster preserves brain function better than other forms of training over twenty years of follow up. That’s according to a …

What is an assembloid? Elizabeth Tracey reports Feb 02, 2026

Show notes

Brain organoids, cell collections grown in a lab to study diseases like Alzheimer’s, have created excitement because they are a bit more representative of a real brain. Johns Hopkins cell engineering expert Vasiliki Machairaki says there is another technique underway …

What is an organoid? Elizabeth Tracey reports Feb 02, 2026

Show notes

Using induced stem cells helps create models for diseases like Alzheimer’s disease that can be studied in a lab, but now three dimensional cell collections called organoids can also be developed from stem cells. Vasiliki Machairaki, a cell engineering expert …

How do stem cells derived from blood differ from those from embryos? Elizabeth Tracey reports Feb 02, 2026

Show notes

Stem cells used to be derived from human embryos, but not anymore. Now a simple blood test can allow stem cells to be induced from cells found there, says Johns Hopkins cell engineering expert Vasiliki Machairaki. Machairaki: Induced pluripotent stem …

Stem cells are just the beginning when it comes to modeling your risk for Alzheimer’s disease, Elizabeth Tracey reports Feb 02, 2026

Show notes

Cells from your blood can be induced to return to what they looked like when you were an embryo, then can be made to develop into different cell types in the brain. That happens in the lab of Vasiliki Machairaki, …
