Summary:
Late-life depression affects a significant proportion of adults over 60 and fewer than half of cases are identified by primary care providers. This article covers how depression presents differently in older adults, why the standard diagnostic approach misses it, what conditions mimic it, and what treatment actually looks like in this age group.

Key Topics:
- Late-life depression prevalence: affects significant proportion of over-65 adults; fewer than half identified
- Irritability as primary presentation rather than sadness
- Fatigue and loss of energy misattributed to aging
- Cognitive symptoms: pseudodementia, concentration difficulties, slowed thinking
- Somatic complaints as primary language of distress in older adults
- Anhedonia: loss of interest expressed as gradual activity withdrawal
- Social isolation that looks like preference
- Why standard PHQ-9 screening misses many presentations in older adults
- Prescribing cascade: depression as medication side effect
- Polypharmacy interaction with depressive symptoms
- Antidepressants in older adults: longer response time, 6 to 8 weeks
- CBT and problem-solving therapy adapted for older adults
- Physical activity: randomized trial evidence for effect sizes comparable to medication

Key Takeaways:
- Late-life depression presents as irritability, fatigue, physical complaints, and cognitive slowing far more often than as sadness.
- Fewer than half of cases in adults over 65 are identified by primary care providers.
- Multiple common medications can produce or worsen depressive symptoms.
- The most useful diagnostic question is whether something has changed from baseline, not whether the person feels sad.
- Structured aerobic exercise has effect sizes in mild to moderate depression comparable to medication.

Who This Is For:
Adults over 60 who have noticed something has changed in how they feel but do not recognize it as depression, and those who care about them.
