A Small Brain-Chemistry Dip in Anxious Adults, and the Choline Pitch That's Coming for It

A 2025 meta-analysis found a small dip in a brain-chemistry signal called choline in adults with anxiety disorders. The effect is real but modest, and the headline "8%" figure is a cherry-picked best-case slice. The paper proposes testing choline supplements and is the first to say nobody has tested them. Here's how to read it before the supplement ads do.

PMS, Postpartum, Perimenopause: Why ADHD Hits Women Harder at Every Hormonal Drop

Estrogen feeds dopamine. ADHD brains run lean on dopamine. Every hormonal drop (PMS, postpartum, perimenopause) hits women with ADHD harder. And about half of them were never diagnosed as girls.

A Bag of Chips a Day Took a Bite Out of Attention

In 2,192 middle-aged Australians, eating more ultra-processed food was tied to slightly worse attention. Memory was untouched. The dementia-risk headline relies on an unvalidated score. Real signal, real caveats.

On Synthroid Isn't the Same as Balanced on Synthroid

A 51,296-pregnancy Israeli cohort separates treated thyroid disease from actually normal labs in pregnancy, and finds the autism signal lives in the gap between them. About half of chronically diagnosed women had at least one abnormal trimester anyway.

After the Scan Goes Clear: What Nobody Tells Parents About Brain Tumor Survivorship

Kids who survive pediatric brain tumors are landing with ADHD and autism at elevated rates vs. the general pediatric population. Younger age at tumor diagnosis means higher risk. Better sleep is the one lever parents can actually pull.

Schools Are Punishing ADHD Kids More Than Kids With Behavioral Disorders. The Federal Data Proves It.

Three years of federal data across all 50 states show students classified under Other Health Impairment get disciplined at roughly double the rate of students classified under Emotional Disturbance.

Same Pill, Different Kid: Why Strattera Works for One Child and Fails Another

A pharmacokinetic study of 86 children reveals that genetics can cause a 10x difference in drug exposure on the exact same dose of atomoxetine. The fix already exists. Most prescribers aren't using it.

The Data Says Your Kids Are Doing Better Than You Think

Fifty years of research and millions of data points say today's kids are more empathetic, more tolerant, and better at self-control than any generation before them. But the story has gaps you need to know about.

One Blood Draw. Six Answers. An AI Model That Spots Dementia Before You Feel It.

Researchers trained an AI on 17,187 blood samples to diagnose Alzheimer's, Parkinson's, FTD, ALS, stroke, and healthy brains from a single tube of plasma.

Your Kid Understands People Fine. Their Brain Just Takes a Different Route.

A meta-analysis of 18 fMRI studies found that autistic brains use alternate neural pathways for Theory of Mind. Different route, not broken route.

Your Brain Has a Volume Knob — And Science Finally Found It

MIT researchers built a computational model revealing why selective listening fails in noisy environments — and why ADHD and autistic brains hit that wall more often.

Social Media Is Coming for Your Kid's Focus. Video Games? Not So Much.

A 4-year study of 8,324 kids found social media specifically drives inattention symptoms. Gaming and TV didn't. Genetics didn't change it.

Why Every Virus Runs the Same Playbook Against Your Brain

A review of 25,000+ patients across six viral infections found that the same inflammatory markers are linked to cognitive decline regardless of which virus caused it. For ND families already managing immune differences, this framework changes how we think about post-viral brain fog.

Sleep Problems in Autism? Look at What Happens During the Day

The largest accelerometer study of sleep and activity in autistic adults finds that daytime physical activity patterns predict nighttime sleep quality - and the penalty for inactivity is steeper in autism.

Your Kid's ADHD and Depression Aren't Two Separate Problems. They're One Blueprint.

A multivariate GWAS of 510,000+ cases reveals that less than 1% of ADHD's genetic variants are unique to ADHD. The rest are shared with depression and bipolar disorder - which means comorbidities aren't bad luck. They're the same underlying architecture expressing differently.

The Invisible Sibling: Your Kid Without ADHD Might Need Support Too

The first major meta-analysis of sibling cognition (32 studies, 8,873 kids) finds children without ADHD who have a sibling with ADHD show a small but real cognitive footprint. This isn't damage - it's shared family wiring.

The 4:1 Myth Is Collapsing: A Massive Study Shows Autism Affects Boys and Girls Almost Equally

A 35-year Swedish study of 2.7 million people reveals the famous 4:1 male-to-female autism ratio is a diagnostic artifact. By age 20, the ratio approaches 1:1. Girls aren't less autistic - they're being missed.

Why Your ADHD Meds Stop Working Once a Month

Estrogen boosts dopamine. When it drops premenstrually, postpartum, or in perimenopause, ADHD symptoms can spike and medications may feel less effective. A psychiatrist explains the science behind the hormone-ADHD connection.

Correlation Isn't Causation (And Why That Matters for Your Family)

The biggest psychiatric genetics study ever made headlines everywhere — and most of them got it wrong. Here's what correlation vs. causation actually means for your family.

The Hidden Layer: What Your Gut Bacteria's DNA Might Reveal About Autism

Researchers found that mutations in gut bacteria DNA — not just which bacteria are present — differ between autistic and neurotypical children.

Does How You're Born Affect ADHD Risk? A Massive Meta-Analysis of 14 Studies Weighs In

A new meta-analysis of 14 studies across 10 countries finds that C-section delivery is associated with (not proven to cause) a modest 12-14% increased risk of ADHD. But context matters: genetics explain ~74% of ADHD risk, while birth factors account for a tiny fraction.

ADHD Doesn't Stop at Your Brain: A 46-Year Study Shows It Affects Your Body Too: What You Can Do About It

A 46-year British study of 10,930 people finds childhood ADHD traits predict more chronic health conditions by midlife — but the association runs through modifiable factors like smoking, BMI, and mental health.
