Abstract Background: Pseudodementia is a cognitive impairment resembling dementia but caused by psychiatric conditions like depression, posing a remarkable diagnostic challenge and treatment outcome. Unlike dementia, pseudodementia is potentially reversible with appropriate treatment of the underlying disorder. Case Report: In this report, we described a case series of three older adult patients who were initially suspected of having dementia. They were under consideration to be placed at a residential facility by their family. After a comprehensive assessment, they were diagnosed with major depressive disorder and received antidepressant therapy. Following treatment, family members reported satisfactory outcomes. All three patients had been able to postpone the time for the placement at a residential facility. Conclusion: This case series stresses the critical importance of considering to treat underlying depressive symptoms in old adult patients presenting themselves with cognitive decline and to facilitate potential functional recovery.
