ADHD Diagnosis

Difficult From the Start? What Toddler Temperament Does — and Doesn’t — Tell Us About ADHD Risk

by

Different readers will use this information differently, and each use carries its own risks.

For healthcare professionals, the temptation runs toward premature labeling; the corrective is understanding that these markers signal elevated risk, not confirmed pathology, and that formal ADHD diagnosis before age four remains discouraged for good reason. For educators and early-childhood programs, the value lies in supporting self-regulation without stigmatizing the child who has not been — and may never be — diagnosed. For governments and policymakers, the finding that caregiver response moderates outcomes — even genetic risk — makes a concrete case for investment in early parenting support, particularly for families under stress. And for the media, the single most consequential job is preserving two lines that headlines routinely erase: the line between “raises the odds of” and “causes,” and the line between “genetic” and “fixed.”

Where to find reliable, independent ADHD information when you want science you can check.

When you have ADHD, weak information is expensive. A glossy site can talk you into a costly supplement that does little, or scare you away from treatment that would help. Government guidance can shift with each administration, leaving you unsure what still holds. And anything funded by a drug maker carries a built-in incentive to favor its product. The cost is not abstract: misinformation delays diagnosis, drains money, and deepens the self-doubt that already follows you. Knowing which sources to trust protects all three.

ADHD and psychosis: what the research actually shows

by

When ADHD and psychosis are confused, the cost is high. A person with emerging psychosis may be treated only for attention problems while the more serious condition goes unaddressed. A person with ADHD may spend years blaming their character for struggles that have a name and a treatment. And fear of a rare medication side effect leads some families to abandon care that works. Getting the relationship right is not academic — it changes whether the correct help arrives in time.

What FDG-PET Studies Show

by

Brain imaging using fluorodeoxyglucose positron emission tomography (FDG-PET) has produced suggestive but inconsistent evidence linking ADHD to altered cerebral glucose metabolism, with the most reproducible findings implicating fronto-striatal and premotor circuits. However, results vary substantially by age, sex, task, and study design, and chronic stimulant treatment does not produce robust metabolic shifts even when symptoms clearly improve. No FDG-PET signature is currently sensitive or specific enough to diagnose ADHD, and the technology remains a research tool rather than a clinical instrument.

ADHD Screeners Glossary.

by

The right screener depends on age, setting, and what you intend to do with the result. A 2025 systematic review of 74 studies covering 40 different ADHD instruments found that short tools perform as well as long ones, free tools as well as paid ones, and a negative screen rules ADHD out far more reliably than a positive screen rules it in.

RSD and Your Partner: Breaking the Reaction Loop

by

Key takeaway

Rejection sensitive dysphoria turns ordinary partner interactions into perceived attacks, and your reaction to that perceived attack typically triggers a real one — closing a loop neither person started on purpose. Breaking it does not require either partner to change personality, suppress feelings, or “communicate better” in the abstract. It requires recognizing the specific moment your nervous system shifts from listening to defending, and choosing a single, repeatable interruption that buys you the seconds you need to respond instead of react.

Why this matters

Untreated, the reaction loop does not stay neutral. It compounds. Each cycle deposits a small layer of resentment, withdrawal, or self-protective distance, and over months and years the relationship hardens around the loop rather than the love. Couples affected by ADHD already face elevated rates of relationship breakdown, and emotion dysregulation is one of the strongest predictors of decline. Catching the loop early — while both partners still want to fix it — is the single highest-leverage move you can make for the relationship.

When ADHD Isn’t ADHD: The Cushing’s Syndrome Connection You Need to Know

by

If you are an adult presenting with attention problems for the first time in your 30s, 40s, or 50s, the default clinical path often leads to an ADHD evaluation, a self-report screener, and a prescription. That path works well when the diagnosis is correct. When it isn’t — when the true driver is a pituitary or adrenal tumor producing excess cortisol — stimulant medication may provide modest symptomatic relief while the underlying disease progresses untreated. Cushing’s syndrome, left unaddressed, carries serious cardiovascular, metabolic, and neurological consequences. The case for accurate differential diagnosis is not academic.

For parents and clinicians, the issue is equally consequential in pediatric cases, where Cushing’s is rarer but does occur — particularly in certain genetic conditions — and where attention and behavioral symptoms may be the earliest presenting complaint.

Is There a Definitive Test for ADHD?

by

This article explains why ADHD has no single definitive test, how clinicians combine the DSM-5 criteria with interviews, rating scales, and differential diagnosis to reach an accurate conclusion, and what makes that process reliable despite its complexity. You will learn what a competent evaluation looks like, why “ruling out” other conditions is a feature rather than a flaw, and how to advocate for yourself if your diagnosis—or someone’s dismissal of your concerns—does not feel right.

ADHD and Allergies: The Hidden Link

by

This article explores the well-documented association between ADHD and allergic conditions, including asthma, allergic rhinitis, atopic dermatitis, and food allergies. You’ll learn what the research shows, why these conditions overlap, what mechanisms may drive the connection, and what practical steps you can take. Whether you’re managing your own symptoms or supporting a child, this knowledge can help you advocate for more comprehensive care.

Cognitive Dissonance and ADHD: When Your Ideal Self Collides with Reality

by

If you have ADHD, you’ve likely experienced the exhausting cycle of promising yourself “tomorrow will be different” while repeating the same patterns. This isn’t a character flaw—it’s cognitive dissonance amplified by ADHD’s unique neurological features. Your brain’s optimistic time perception, difficulty with self-monitoring, and tendency toward black-and-white thinking can blur the line between who you aspire to be and who you actually are. Recognizing this pattern helps explain why traditional productivity advice fails you, why you might feel like you’re “faking” struggles, and why self-compassion is essential for genuine progress.

504 Plan or IEP?

by

When dealing with ADHD (Attention-Deficit/Hyperactivity Disorder), one of the most common challenges parents encounter is deciding between a 504 Plan and an IEP (Individualized Education Program). ADHD impacts “executive function,” which is the brain’s management system. As a result, it can present as either an obstacle to learning or a requirement for specialized instruction.
