Depression vs low mood: how to differentiate them
Everyone experiences "the blues." But where does normal low mood end and depression begin? This comparison table clarifies the criteria for knowing when to seek help.
Comparison table
| Criterion | 🟡 Low mood (normal reaction) | 🔴 Depression (pathology) |
|---|---|---|
| Duration | Days to a few weeks | Minimum 2+ weeks, often months |
| Cause | Response to an identifiable difficult event | Not always linked to a clear event |
| Pleasure | Can find pleasure in activities | Anhedonia: nothing brings pleasure |
| Mood | Fluctuates, improved by good news | Stable and low, does not respond to positive events |
| Sleep | Occasionally disturbed | Chronically disturbed (insomnia or hypersomnia) |
| Appetite | Slightly modified | Significantly reduced or increased |
| Energy | Temporary reduction | Deep, persistent exhaustion |
| Functioning | Maintained with effort | Seriously compromised at work and home |
| Suicidal thoughts | Absent | May be present — warning sign |
| Natural evolution | Spontaneously diminishes | Persists without treatment, often worsens |
⚠️ Warning signs — consult without delay
• Sadness persisting for more than 2 weeks without improvement
• Total loss of pleasure in all activities (anhedonia)
• Thoughts of death or suicidal ideas — even fleeting
• Inability to function at work or at home
• Loved ones expressing their concern
• Unexplained physical symptoms (pain, chronic fatigue)
Disguised depression in elderly people
In seniors, depression often masks itself in atypical forms: multiple somatic complaints (pain, digestive issues without organic cause), irritability and agitation rather than expressed sadness, withdrawal and refusal of care. It can also mimic early dementia (depressive pseudodementia). The vigilance of loved ones and professionals is essential.

FAQ
Difference between depression and low mood?
Low mood: reactive, short, possible pleasure. Depression: persistent (2+ weeks), total anhedonia, major functional impact, not linked to a clear event.
When to consult?
If sadness persists for 2+ weeks, anhedonia, suicidal thoughts, functional incapacity, or concern from loved ones. Do not wait.
Can low mood evolve into depression?
Yes, especially with a history of depression, isolation, or chronic stress. Do not wait more than 3-4 weeks without improvement.
Conclusion: do not trivialize, do not dramatize
Low mood deserves to be taken seriously — including to prevent it from evolving into depression. But it does not require psychiatric treatment: social support, physical activity, exposure to light, and stress management are usually sufficient. Depression, on the other hand, requires professional help. The DYNSEO stress and anxiety test can help objectify what one feels before a consultation.
