ADHD stimulants appear to work less by sharpening focus and more by waking up the brain. Brain scans revealed that these medications activate reward and alertness systems, helping children stay interested in tasks they would normally avoid. The drugs even reversed brain patterns linked to sleep deprivation. Researchers say this could complicate ADHD diagnoses if poor sleep is the real underlying problem.

Researchers found distinct electrical firing patterns that could identify these conditions with high accuracy. The discovery opens the door to more precise diagnoses and personalized drug testing. Instead of guessing medications, doctors may one day see what works before treating the patient.

Alarmingly, safety was often ignored, with many treatments never properly evaluated for side effects. The researchers stress that looking at the full body of evidence matters far more than trusting a single hopeful study.
