Key Highlights
•
A specific sleep brainwave pattern, called a low “A2 index” in the cyclic alternating pattern (CAP), is linked to a doubled risk of developing dementia in older men. This suggests that analyzing sleep EEG for CAP features could be a more powerful tool for predicting dementia risk than traditional sleep measurements.

Researchers have identified a new, non-invasive brain stimulation technique called temporal interference stimulation that can target deep brain regions with precision. This advancement could lead to more effective and personalized treatments for psychiatric conditions like depression, moving beyond the limitations of current brain stimulation methods.

In people with restrained eating patterns, their ability to rapidly process visual information (an “attentional blink”) can be influenced by sound and by gently stimulating a specific part of the brain’s frontal lobe (the DLPFC). This finding helps explain how brain circuits for attention and perception are connected to eating behavior, opening new avenues for research into eating disorders.
