Depression in Dementia

We chose depression as the first BPSD to discuss, not only because of its high prevalence in people with dementia but also because of the challenges in identifying depression in these patients in a busy clinical setting. This difficulty is particularly pronounced because of the overlap of symptoms between the two conditions, the lack of standardized diagnostic criteria, and the low reliability of self-report and informant-based measures. Missing the diagnosis of depression can lead to grave consequences, given its strong association with an increased risk of suicide and the exacerbation of cognitive decline and functional impairment. Moreover, the clinical course, treatment, and prognosis differ significantly between patients with depression and those without. Despite these challenges, there are scales to assist in the assessment and diagnosis of depression in dementia. Additionally, a comprehensive and person-centered treatment approach, integrating both nonpharmacological and pharmacological interventions, can be effective in managing depression in individuals with dementia. Hence, it is crucial for clinicians to possess the necessary knowledge and skills to identify and manage depression in people with dementia.
