The Brain’s Attention Network: More Than Just ADHD
Attention is not one thing. It is several networks doing different jobs — and stress, sleep loss and anxiety impair them in everyone, not only in people with ADHD.
Could Inflammation Be Affecting Your Brain?
Low-grade inflammation was found in 27% of people with depression. Here is what the evidence supports about inflammation, brain fog and mood — and what it does not.
The Science of Resilience: Why Some People Recover Faster
Resilience is not toughness. It is recovery speed — how quickly a nervous system returns to baseline after activation — and that is a measurable, trainable property.
The Brain and Perimenopause: A Neurological Transition
Brain fog, disrupted sleep and new anxiety during midlife are not imagination. Perimenopause is a neurological transition, and imaging research shows measurable changes in brain energy metabolism.
The Developing Teenage Brain: Why It Isn’t “Broken”
Adolescence is not a defective phase of adulthood. It is a period of intensive remodeling — pruning, myelination and rebalancing — and the behavior that worries parents is largely a product of the sequence.
How Exercise Changes the Brain at Any Age
One year of aerobic exercise grew older adults’ hippocampus by about 2% while the control group shrank. Here is the mechanism behind the single best-evidenced intervention for brain health.
The Brain’s “Smoke Alarm”: Understanding the Amygdala
The amygdala is fast, ancient and deliberately imprecise. Here is how it protects you, why it becomes overprotective, and what actually turns the volume back down.
What Happens Inside the Brain During a Migraine?
A migraine is a brain event, not a headache. Here is what cortical spreading depression is, why light and sound become unbearable, and why the attack starts hours before the pain.
Why Children’s Brains Need Boredom
Unstructured time is not wasted time. Here is what happens in a child’s developing brain during boredom and free play — and why the American Academy of Pediatrics tells doctors to prescribe it.
The Hidden Cost of Constant Stress on the Brain
Chronic stress does not just feel bad — it physically remodels the brain, strengthening the threat system while thinning the regions that regulate it. Here is what changes, and what recovers.
