🧠 ADHD: An Evidence Hub
Attention-Deficit / Hyperactivity Disorder (ADHD) affects roughly 5-7% of children and 3-5% of adults. Diagnostic criteria have evolved (DSM-5, 2013 onward), and adult-ADHD recognition has expanded rapidly since the 2018 European Consensus Statement. This hub curates our systematic-review-based articles on ADHD diagnosis, treatment, and life-support strategies.
1. What ADHD actually is
ADHD is a neurodevelopmental profile defined by three core symptoms — inattention, hyperactivity, impulsivity — with onset before age 12 and persistence for 6+ months across settings (DSM-5). Modern framing treats ADHD as a spectrum of information-processing differences, not a binary illness.
📌 Editorial note: ADHD is dimensional, not categorical. Diagnosis is warranted when symptoms interfere with daily life; support is often possible without a formal label.
2. Adult ADHD — underdiagnosis and criteria
Adult ADHD is now recognized as a lifelong trait, not a "childhood disorder that fades." Recent meta-analyses estimate a ~3% global adult prevalence, with significant under-recognition especially in women and in cases that surface post-partum or post-career-change.
3. Child ADHD — early recognition
Children with ADHD are most often identified between ages 5-8, at the transition into structured schooling. Early support — via parent training, environmental adjustments, and (in older kids) exercise interventions — reduces cascading impacts on self-esteem, learning, and peer relationships.
4. Treatment options
💊 Medications
Methylphenidate, atomoxetine, guanfacine. Effect sizes are among the largest in psychiatry, but continuation and side-effect trade-offs matter.
🧘 Cognitive Behavioral Therapy
ADHD-specific CBT programs have gained the strongest evidence for adults.
🏃 Exercise interventions
Aerobic exercise improves attention and executive function in children with ADHD (adjunct therapy).
😴 Sleep optimization
Sleep disorders are highly comorbid with ADHD. Fixing sleep alone can reduce symptom severity.
5. Comorbidities
ADHD rarely presents in isolation. Frequently comorbid conditions include:
- Autism spectrum disorder (ASD)
- Anxiety disorders and depression
- Sleep disorders
- Substance-use tendencies
