Understanding neurodivergence
Articles based on published research: ADHD, autism, dyslexia, mood, sleep, and what actually helps.
Rewards in ADHD and Autism: Same Brain Regions, Opposite Responses
A 2026 meta-analysis of 29 brain imaging studies suggests that ADHD and autism involve the same deep reward regions, but that these regions respond in opposite directions when a reward arrives. What it shows, what it could mean for motivation, and its limits.
Three Types of ADHD? What the 2026 Brain Scan Study Really Found
Posts say scientists have "discovered 3 types of ADHD." A real JAMA Psychiatry study did find three brain-based subgroups in children with ADHD. Here is what it showed, what a "biotype" is, and why it is not a diagnostic scan.
Hundreds of Autism Genes, Two Brain States: What the New Science Study Shows
A September 2026 study in Science found that mice carrying very different autism-risk mutations fall into just two opposite patterns of brain gene activity. It changes how researchers think about autism's diversity. It does not create autism subtypes, tests or treatments.
A Brainstem "Attention Filter" and ADHD: What the Mouse Study Really Shows
A viral post says researchers found a brainstem attention filter that may explain ADHD. The study is real and published in Nature Communications. But it was done in mice, and it contains no one with ADHD.
When Do Autism and Schizophrenia Begin? A Study of 1,000 Brains Points to the Months Before Birth
A University of Exeter team mapped the chemical switches on DNA in nearly 1,000 human brains, from six weeks after conception to 108 years. Most of the change happens before birth, and the genes linked to autism and schizophrenia are right in the middle of it. What that means, and what it does not.
The Gut-Brain Serotonin Highway: How Your Intestines Talk to Your Brain via the Vagus Nerve
A 2025 review maps out how gut-produced serotonin reaches the brain through the vagus nerve, a real biological reason gut health, mood and neurodivergence often show up together.
ADHD Is Real: What Brain Imaging and Genetics Actually Show
A viral post lists four kinds of evidence that ADHD is a real, biological condition. We checked each claim against the actual studies - here is what holds up.
ADHD and Autism Show No Evidence of Accelerated Brain Aging, New Study Finds
A large 2026 neuroimaging study in PLOS Medicine compared nine neurological and psychiatric conditions. The result: neither ADHD nor autism showed premature brain aging.
Copper and the Brain: What the Science Says (and Why Hair Mineral Tests Are Not the Answer)
Copper is genuinely important for brain chemistry, but hair tissue mineral analysis is not a validated way to test it. Here is what the actual research says about copper, mood, cognition and sleep.
"Brain Fog Genetics": A Checklist of 15 Genes Across 6 Conditions. Here's What Actually Holds Up.
A viral genetics checklist links brain fog to celiac disease, lupus, POTS, inflammation, oxidative stress, and "detox genes" for mold toxins. One of these has solid evidence. Several are real conditions with unproven gene-to-symptom links. One is a red flag straight out of consumer-genetics marketing.
Are Autism and Schizophrenia "Byproducts" of Human Intelligence? Here's the Real Study.
A viral post claims autism and schizophrenia are natural byproducts of the genes that made human intelligence possible. There is a real 2024/2025 study behind this - but the researchers themselves are far more cautious than the post lets on, and one of its central claims doesn't hold up at all.
Genetics and Serotonin Keep Showing Up in ADHD Content. Here's What's Actually Solid.
TPH1/TPH2, SLC6A4, HTR1/HTR2 - serotonin gene explainers are everywhere right now. Some of it is textbook-accurate. Some of it is one researcher's theory presented as settled fact. And serotonin isn't even ADHD's primary biology - here's where it actually matters.
