Health insights and strategies for neurodivergent families
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 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.
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.
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.
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.
Researchers found that mutations in gut bacteria DNA — not just which bacteria are present — differ between autistic and neurotypical children.
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.
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.
