Abstract
This chapter highlights the complexity of the relationship between enhancement of mood and cognition on the one hand and the improvement of people's well‐being on the other. To do so, two psychiatric conditions, Asperger's syndrome and bipolar disorder, are presented in the chapter. Even though there are both negative and positive aspects to Asperger's syndrome or to bipolar disorders, taking away even these negative aspects would not necessarily promote well‐being. It might also be impossible to isolate the positive aspects of these disorders. An increase in specific forms of cognition might be intrinsically connected to a decrease in specific aspects of mood. A decrease in specific aspects of mood might be intrinsically connected to an increase in creativity. Neither is necessarily linked to any changes in some general form of “well‐being.”.
