Depression in Kidney Disease: Common, Treatable, Ignored

The hidden epidemic

Depression in dialysis patients runs 20-30% — and it's not a psychological footnote: it independently predicts hospitalizations and death, in part through adherence, nutrition, and inflammation. Yet screening is rare, and the symptoms hide inside uremia's shadow: the patient is 'just tired, just losing appetite' — which is exactly the depression we're missing.

Caregivers and family carry weight too: depression in caregivers is common, and supporting them supports the patient.

Treatment with kidney notes

Psychological therapy (CBT) is effective and drug-free — and increasingly delivered via telehealth. Antidepressants are generally safe in CKD: sertraline and fluoxetine need little adjustment; citalopram is capped at lower doses (20 mg) in kidney impairment; avoid those with significant renal handling unless adjusted.

Exercise — including during dialysis sessions — improves depression scores in trials. Addressing sleep, anemia, and pain simultaneously boosts treatment response.

The screening ask

Two questions catch most cases (PHQ-2): 'In the last 2 weeks, have you felt down, depressed, or hopeless?' and 'Had little interest or pleasure in doing things?' — followed by the full PHQ-9 when positive. Ask these routinely at clinic visits; the answers change management more than most lab values.
