Amotivational syndrome associated with selective serotonin reuptake inhibitors in children and adolescents.

A frontal lobe syndrome has previously been reported in adults treated with selective serotonin reuptake inhibitors (SSRIs), but not in children. Five typical cases of apathy and lack of motivation, one accompanied by disinhibition, are described in a child and four adolescents. Symptoms were dose related and reversible. The subtlety of symptoms, lack of insight in patients, disabling effects, and delayed onset indicate a need for clinicians to inform families of these potential symptoms when SSRIs are prescribed.
