- literature analysis of ADHD prevalence vs solar intensity
Key findings
- An EEG subgroup with low vigilance (raised frontal theta and alpha) responds well to stimulants and neurofeedback
- A slow alpha peak frequency subtype (about 25-30% of ADHD patients) responds poorly to stimulants
- Sunlight intensity explained 34-57% of worldwide ADHD prevalence, with lower prevalence in high-sunlight regions
- Author proposes sunlight normalizes circadian clock disruption, suggesting possible prevention
A Dutch-language review on personalized treatment of ADHD and the role of sleep. It describes an EEG subgroup with reduced vigilance (raised frontal theta and alpha) that responds well to stimulants and neurofeedback and appears linked to shortened sleep. To test a model linking the circadian clock to ADHD, the author compared ADHD prevalence studies that used identical methods with worldwide sunlight intensity data, finding lower prevalence where sunlight is stronger. He suggests sunlight may protect by normalizing circadian disruption, which could point toward prevention.
