Prevalence and Predictors of Neurocognitive Dysfunction in Adults With Congenital Heart Disease: Results From MINDS-ACHD
Authors' conclusion
NCDs are prevalent in young adults with moderate and severely complex CHD, with approximately one-third having objective NCDs and one-fifth subjective NCDs.
Study context
- Population
- Young adults (18–30 years) with moderate and severe complex congenital heart disease
- Participants
- 467 adults
- Exposure
- dextro-transposition of the great arteries vs tetralogy of Fallot vs single ventricle vs other congenital heart disease (CHD)
- dextro-transposition of the great arteriesn = 82
- tetralogy of Fallotn = 123
- single ventriclen = 132
- other CHDn = 130
- Outcome
- Prevalence of neurocognitive deficits: objective (NIH Toolbox cognitive battery) and subjective (NeuroQOL Item Bank v2)

Further findings
Predictors of NIH Toolbox scores (multivariable regression)
- Education and NYHA functional class independently associated with NIH Toolbox scores
Predictors of NeuroQOL scores (multivariable regression)
- Education, BMI, atrial arrhythmias, depression and anxiety independently associated with NeuroQOL scores
