Guidelines for youth depression: time to incorporate new perspectives

Abstract

TO THE EDITOR: I cannot argue with the push by Hickie and McGorry for services for young people from 12 to 25 years of age who suffer from “depression”. But I question their sequencing of treatments model that pervades the beyondblue draft clinical practice guidelines about which they editorialise. Their model presupposes a unitary entity of “major depression” that varies in severity, with milder conditions being treated by psychotherapy and more severe conditions being treated with antidepressant medication. Consider the following case to show how the guidelines get it wrong. A 16-year-old girl presents with her first episode of moderately severe major depression. She is treated as per the guidelines for depression with a selective serotonin reuptake inhibitor (SSRI) and rapidly develops a severe psychotic mania. She is certified to a psychiatric facility and requires a prolonged admission. For the next 2 years she remains chronically hypomanic, refusing to try better treatment. Eventually, following a severe depressive episode, her treatment is reorganised and her condition stabilises. However, the trauma and psychosocial damage from the hospitalisation and prolonged period of illness are significant. In the guidelines, bipolar disorder — arguably the only “biological” kind of depression in this age group — is separated from the body of recommendations for managing depression. The possibility that this episode of depression may be part of an asyet-undeclared bipolar disorder needs to be thoroughly integrated into the understanding and management of “depression”. Features that would suggest possible bipolar disorder include psychomotor retardation and cognitive impairment, psychosis, reverse neurovegetative features (hypersomnia or hyperphagia), a few manic symptoms mixed with depression (racing thoughts, distractibility, flight of ideas, increased energy or psychomotor agitation), or the depression not making sense psychologically. Past episodes of depression, brief hypomania, anti-depressant-induced hypomania, or a family history of bipolar disorder also need to be documented. Doctors should then routinely discuss with patients and families the possibility that bipolar disorder could be diagnosed, and warn that the patient may experience a manic switch. If the likelihood is high, as part of a proper process of informed consent, the patient should be offered concurrent lithium or antipsychotic medication. The patient and family can be assured that expert clinical observation over time will clarify the diagnosis and what treatment is appropriate. This approach not only involves the patient and family in decision making, giving knowledge and choices, but, importantly, incorporates the reality of diagnostic uncertainty.
