Key facts
- Ultraprocessed diets may be linked to an increased risk of dementia.
- New research is exploring the similarities between anesthesia and comas.
- A radiation device for brain tumors shows potential.
This week's WSJ Health newsletter highlights several health-related research findings. One study suggests a potential link between the consumption of ultraprocessed diets and an increased risk of developing dementia. In other medical research, scientists are investigating anesthesia, with findings indicating it may be more akin to a coma than previously understood. Furthermore, a new radiation device designed for treating brain tumors has demonstrated promising results.
