Athymhormia
Athymhormia is a disorder of motivation, one of that class of neuro- psychiatric conditions marked by abnormalities or deficiencies in motivation. Symptoms include the loss or reduction of desire and interest toward previous motivations, loss of drive and the desire for satisfaction, curiosity, the loss of tastes and preferences, and flat affect. In athymhormia, however, these phenomena are not accompanied by the characterizing features of depression nor by any notable abnormality in intellectual or cognitive function.
