Loss of interest in life can have various causes, just like most other symptoms. Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.
Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms. In order to diagnose loss of interest in life, we could:
some loss of muscle tone
antidepressant drug use
frequent unexplained sadness/crying
frequent night terrors
increased skin wrinkling
increased focal length
poor reaction to cool damp weather
attempting suicide
having trouble concentrating
being highly lethargic
weak appetite
much reduced sense of taste| Cause | Probability | Status |
|---|---|---|
| Premature Aging | 94% | Confirm |
| Depression | 62% | Possible |
|
Do you have an overall loss of interest or pleasure in activities that you once enjoyed, due to depression or unknown reasons? If you are still interested but can't enjoy these activities due to fatigue, poor health, lack of time, or stress, answer "No".
Possible responses:
→ Don't know / I never had many interests→ No → Slight loss of interest → Moderate loss of interest → Complete or almost complete loss of interest |
