Copy Number Variants Did Not Moderate ADHD or Autism Outcomes in ALSPAC

Photoreal illustration of DNA strands and developmental timeline overlaid on a schematic young adult, conveying genetic moderation of childhood neurodevelopmental outcomes.

A 2026 ALSPAC analysis tested a narrow claim behind routine genetic screening for childhood attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD): whether rare copy number variants (CNVs; deleted or duplicated DNA segments) make young-adult outcomes worse than ADHD/ASD status alone would predict. In 8,414 people with usable CNV data, ADHD and ASD predicted worse …

1 mg Guanfacine for Self-Harm Thoughts in ADHD-PTSD-BPD Case

MHD featured image for 1 mg guanfacine and self-harm thoughts in complex ADHD, PTSD, BPD, and ASD comorbidity.

A 2026 case report linked 1 mg nightly guanfacine modified-release to first-ever cessation of intrusive deliberate self-harm thoughts in a 16-year-old with attention-deficit/hyperactivity disorder (ADHD), autism spectrum disorder (ASD) traits, borderline personality disorder (BPD) traits, and post-traumatic stress disorder (PTSD). The same case became more interesting after the patient stopped taking guanfacine and the self-harm …

Intellectual Disability in Korean Children and Psychiatric Disorders (ADHD 42%, Depression 19%)

Photoreal illustration of a child interacting with cognitive and developmental motifs, representing intellectual disability and psychiatric comorbidity.

Children with intellectual disability are 3–4x more likely to have a comorbid psychiatric disorder than peers without ID. A 2026 nationwide Korean study by Joo and colleagues tracks how those rates changed across a decade.1 Research Highlights Korean children and adolescents (ages 2–18) with intellectual disability had ADHD comorbidity rise from 30.2% in 2012 to …

ADHD Genetics Linked to Autism & Schizophrenia But Not Other Psychiatric Conditions (2024 Study)

Attention Deficit Hyperactivity Disorder (ADHD) is a complex neurodevelopmental condition that significantly impacts individuals’ lives. Recent advancements in genetic research, particularly Mendelian Randomization (MR) studies, have begun to unravel the intricate genetic associations between ADHD and other psychiatric disorders, offering new insights into their comorbidities. By leveraging data from genome-wide association studies (GWAS), this research …

Low Adiponectin Levels in Children with Autism Spectrum Disorder (ASD): Correlation with Symptom Severity (2024 Study)

In the intricate puzzle of autism spectrum disorders (ASD), emerging research highlights a fascinating piece: the role of adiponectin, an anti-inflammatory adipokine, in the development and severity of ASD in children. With the backdrop of increasing ASD prevalence and the quest for biomarkers for early identification, the exploration of adiponectin offers a promising avenue for …
