Attention deficits, often associated with ADHD in children, may in some cases originate from causes other than a strict concentration dysfunction. Recent studies suggest that the attention deficit observed in some children is closely linked to sleep deprivation, which is sometimes underestimated at the time of diagnosis.
Symptoms that are easily confused with chronic fatigue
A large study of thousands of children shows that psychostimulant medications prescribed for ADHD primarily activate brain areas associated with wakefulness and alertness, without any direct measurable effect on those involved in attention. In other words, these treatments appear to mainly compensate for drowsiness or reduced alertness, rather than improving attentional abilities themselves. These results were confirmed in adults without ADHD who were exposed to the same substances on a one-off basis.
Researchers are warning of a risk of diagnostic confusion: a child suffering from sleep disorders may exhibit academic difficulties, restlessness, or inattention similar to those of ADHD. Without a thorough sleep assessment, these signs can lead to inappropriate treatment. Specialists are now calling for the systematic integration of sleep habit and quality analysis into treatment plans, emphasizing that no medication can permanently replace sufficient rest.
