Five themes were identified. First, perceptions of respectful or disrespectful communication affect the relationship with clinicians and contributes to positive or negative communication experiences. Second, participants described the emotional impact of sudden or unsupported disclosures, in which they felt unprepared to receive the news or emotionally abandoned after diagnosis. Third, the absence of, or ambiguity around, a definitive dementia diagnosis contributes to patient and caregiver distress and to feeling dismissed by clinicians. Fourth, mixed responses to illness education and clinician recommendations after disclosure reveals the need for more personalized and comprehensive care planning. Fifth, careful consideration around the timing of prognostic communication and advance care planning discussions is necessary to meet the needs of patients and caregivers with different emotional readiness, illness beliefs, and information preferences.ConclusionDementia diagnostic disclosure would benefit from a structured yet tailored communication approach that prioritizes respectful communication, emotional support, and comprehensive care planning to meet the needs of patients and caregivers.</p>","PeriodicalId":16028,"journal":{"name":"Journal of Geriatric Psychiatry and Neurology","volume":" ","pages":"431-452"},"PeriodicalIF":2.5,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145301477","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While antipsychotics are commonly prescribed, their use is limited by safety concerns. Selective serotonin reuptake inhibitors (SSRIs), such as citalopram and escitalopram, have emerged as alternative treatments with a more favorable safety profile. This study aimed to evaluate the efficacy and safety of these agents in the management of agitation in AD.MethodsWe conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) comparing citalopram or escitalopram with placebo or other pharmacological treatments in older adults with AD and clinically defined agitation. Primary outcomes included changes in agitation severity, assessed by the Neuropsychiatric Inventory-Clinician Rating (NPI-C) and the Neurobehavioral Rating Scale (NBRS). Secondary outcomes included cognitive function (MMSE), anxiety symptoms, and adverse events. Standardized mean difference (SMD) and risk ratio (RR) were pooled using a random-effects model.ResultsFour RCTs comprising 502 patients were included. Pooled analysis showed no significant improvement in agitation severity (SMD -0.67; 95% CI -2.58, 1.25; I² = 98.3%) or cognitive outcomes (SMD 2.43; 95% CI -2.55, 7.41).

Here, we investigated online metamemory appraisal for verbal and visuospatial material in patients with MCI due to AD.
