Abstract

Background: Patients with depression and mild cognitive impairment (MCI) are at greater risk of developing dementia. Depression involves a higher risk of suicidal ideation (SI) and suicide attempts (SA). Biomarkers of Alzheimer's Disease (AD) could help to clarify the role of depression and SI in AD.

Method: Fifty-nine participants aged > 50 with criteria of MCI positive (MCI-AD) (n=22) and negative (MCI-Non AD) (n=24) AD and healthy controls (HC) (n=13) were evaluated. We used the Geriatric Depression Scale (GDS-30) and the GDS-SI factor to measure depression and indirect risk for suicide, respectively. Additionally, AD biomarkers such as amyloid-ß (Aß), hyperphosphorilated tau (P-tau), and total tau (T-tau) in cerebrospinal fluid (CSF) were analyzed.

Results: No significant differences between the groups were found in depression. However, in the MCI-AD group, lower P-tau and T-tau levels were related to higher GDS-SI scores, suggesting that MCI-AD patients with lower AD pathology are at a higher risk of suicide.

Conclusions: The result highlights the importance of considering SI in the initial phases of AD, and the potential role of AD biomarkers in early detection of symptoms.

轻度认知障碍患者的抑郁和自杀风险:阿尔茨海默病生物标志物的作用

背景:患有抑郁症和轻度认知障碍(MCI)的患者发生痴呆的风险更高。抑郁症涉及更高的自杀意念(SI)和自杀企图(SA)的风险。阿尔茨海默病(AD)的生物标志物可以帮助阐明抑郁症和SI在AD中的作用。方法:对59名年龄> 50岁，MCI阳性(MCI-AD) (n=22)和MCI阴性(MCI- non -AD) (n=24)和健康对照组(HC) (n=13)进行评价。我们分别使用老年抑郁量表(GDS-30)和GDS-SI因子来测量抑郁和间接自杀风险。此外，还分析了AD生物标志物，如脑脊液(CSF)中的淀粉样蛋白- β (asβ)、过度磷酸化tau (P-tau)和总tau (T-tau)。结果:两组患者抑郁程度无显著差异。然而，在MCI-AD组中，较低的P-tau和T-tau水平与较高的GDS-SI评分相关，这表明具有较低AD病理的MCI-AD患者自杀风险较高。结论:该结果强调了在阿尔茨海默病初期考虑SI的重要性，以及阿尔茨海默病生物标志物在早期症状检测中的潜在作用。
