Depression Affects About 1 in 9 Children With ADHD, Review Finds

Girls show roughly double the risk; how clinicians measure depression matters.

A new systematic review and meta‑analysis of 24 studies estimates that 11.3% of children and teens with ADHD also meet criteria for depression—far higher than in neurotypical peers. In case‑control studies, the pooled depression rate was 12% in ADHD groups versus 2% in comparison groups.  

Key numbers

  • Overall rate: 11.31% across 24 studies (n≈6,800 participants; ~5,000 with ADHD), with wide variation across studies. Heterogeneity was high (I²≈91%).    
  • By sex: Girls with ADHD had a pooled depression rate of 20.9% vs 9.0% in boys.  
  • How it’s measured matters: Studies that combined interviews and questionnaires reported the highest rates (20.9%), followed by questionnaires alone (16.1%) and interviews alone (8.4%).  
  • Who reports symptoms: Rates didn’t differ significantly by informant, but parent‑only reports were highest (24.4%), while youth‑only reports were lowest (9.5%).  
  • Age & treatment: Rates trended higher after puberty (15.1% vs 9.9% pre‑puberty; not statistically significant). Depression rates did not differ significantly between studies with vs without ADHD medication use (10.9% vs 17.8%).    

Why this matters

Depression alongside ADHD can worsen daily functioning and raise risks such as self‑harm; spotting it early lets families and clinicians add targeted supports. The authors note that differences in assessment tools likely drive some of the spread in results—screening scales tend to yield higher estimates than diagnostic interviews, and there’s a shortage of depression tools validated specifically for youth with ADHD.    

What families can do

  • Ask for routine mood screening during ADHD evaluations and follow‑ups, especially for girls and during adolescence.    
  • Request multi‑informant assessments (youth + parent, and clinician input when possible) to get a fuller picture.  
  • Clarify how depression was assessed (questionnaire vs clinical interview) and what next steps follow a positive screen.  

Caveats

Most studies were cross‑sectional, female participants were under‑represented, and key details like socioeconomic status and ethnicity were often missing—limiting how precisely results generalize across communities. The authors call for larger, more diverse studies and ADHD‑specific, validated depression measures.
