SSRI-induced apathy syndrome: a clinical review.

The authors review the literature pertaining to selective serotonin reuptake inhibitor (SSRI)-induced apathy syndrome. A literature search of Medline and International Pharmaceutical Abstracts from 1970 to the present was performed for relevant articles. Twelve relevant case reports and one open-label treatment trial were identified. An amotivational, or apathy, syndrome has been reported in a number of patients receiving SSRI treatment over the last decade. This adverse effect has been noted to be dose-dependent and reversible, but is often unrecognized. This phenomenon has caused significant negative consequences for adults as well as social and academic difficulties in adolescents.
