disorder due to a general medical condition (including substanceinduced depression). Detailed information on the clinical assessment of children and adolescents with depression can be found elsewhere [13].
Other Factors Associated with Poor Treatment ResponseOther than the correct diagnosis of depression, clinicians should explore other factors which contribute to poor treatment response. Exploring other factors leading to treatment-resistant depression will also guide why a patient is not responding. Depressed adolescent patients with a history of abuse, especially physical abuse, had a poorer response to combination treatment with medication and psychotherapy [14]. These patients with a history of abuse may require specialized treatment. Adolescents with treatment-resistant depression had better treatment response if substance abuse-related impairment was low at baseline or reduced during treatment [15]. Suicidal adverse events during treatment of adolescent refractory depression were predicted by high suicidal ideations, family conflict and drug abuse at baseline. These predictors of suicidal adverse events also predict poor treatment response, and hence targeting suicidal ideations, family conflict and drug abuse can improve treatment outcomes [16]. Parent-child conflict has a bidirectional relationship with treatment outcome in adolescent treatment resistant depression [17]. Anhedonia in depressed adolescent's refractory to medication treatment predicted longer time to remission and fewer depression-free days [18]. Depression severity and subsyndromal manic symptoms predicted poor treatment response in this sample [19]. There is also suggestion that adjunctive sleep medication to SSRI treatment in this sample may be associated with poor response [20]. Interestingly, if treatment ends during school summer break,
AbstractTreatment nonresponse in adolescent depression is a major public health problem, as untreated depression is associated with significant mortality by suicide, protracted course of illness, and recurrence into adulthood. Even with the gold-standard treatment with a Selective Serotonin Reuptake Inhibitor (SSRI) and concurrent Cognitive Behavioral Therapy (CBT), 30% to 40% will not respond to treatment, thus classified as "treatment-resistant". These depressed adolescent patients who are refractory to first-line treatments are often in such mental anguish that they are not functioning, and some have considered their only option left to end the misery is to suicide. These are the patients who are often referred to psychiatry, but the treatment options for adolescents with treatment-resistant depression are limited due to lack of research in this area. This review will consider the various treatment options that may help to alleviate the suffering of adolescents afflicted with this devastating illness, with the caveat that there are few controlled studies focused on refractory depression in adolescents.
