A person suffering from burnout no longer manages to overcome everyday stressful events and experiences “emotional fatigue”. It is however difficult to estimate the prevalence of burnout in the population, as, for instance, it can be hard to distinguish it from depression. Attention deficit hyperactivity disorder, on the other hand, occurs among 3% to 6% of children of school age, and boys suffer from this state 2 to 3 times more often than girls.
