Melancholic Depression

With melancholic features” is a DSM-5 specifier added to a major depressive episode when it’s more severe: profound anhedonia with very limited mood improvement even with anticipated good events, and psychomotor retardation that’s noticeable to carers. “Mood is often worse in the morning, with early waking, significant weight loss, and excessive guilt — see full criteria and pharmacotherapy detail on Major Depression.

Diagnostic criteria

One of:

1. Loss of pleasure in almost all activities.
2. Lack of reactivity to usually pleasurable stimuli — the patient doesn’t feel much better, even temporarily, when something good happens.

Plus three or more of:

1. A distinct quality of depressed mood — profound despondency, despair, moroseness, or an “empty” mood.
2. Mood regularly worse in the morning.
3. Early-morning awakening (at least 2 hours before the usual time).
4. Marked psychomotor agitation or retardation.
5. Significant anorexia or weight loss.
6. Excessive or inappropriate guilt.

Notes on applying this specifier: it requires a near-complete absence of pleasure, not merely a reduction — even highly desired events produce no brightening of mood, or only a partial one (e.g. 20–40% of normal, for minutes at a time). The distinct quality” of mood is experienced as qualitatively different from a non-melancholic depressive episode, not just more severe or longer-lasting. “Psychomotor changes are nearly always observable by others. Melancholic features recur only modestly across episodes in the same person; they’re more common in inpatients than outpatients, more likely in more severe episodes, and more likely alongside psychotic features.
