The purpose of this research is to review the association between the dementia diagnosis and suicide risk, to debate what to expect on this topic in the future, and to identify some strategies to control suicide risk after dementia diagnosis.

Non-systematic review of the literature with selection of scientific articles published in the last 10 years, using PUBMED as database and the following keywords: «suicide», «dementia» and «dementia diagnosis». Nine studies were included.

Nowadays, suicide account for one million deaths worldwide per year. Suicide rates are up to 8 times higher in the elderly than in general population, in relative numbers. Dementia is an incurable diagnosis and usually result in loss of mental competence. After being diagnosed with dementia, people face emotional challenges and use to feel loss, anger, and uncertainty.

Different studies found dementia as an independent risk factor for suicide. Also, some factors that increase the risk for suicide in dementia are described: the existence of psychiatric comorbidity, such as depression, anxiety, psychosis and substance use; The initial stages of dementia, often within three months of diagnosis, because the person perceive a higher threat to his life, with progressive physical and cognitive impairment, increasingly higher levels of dependence and concern on becoming a burden for their family, and, at the same time, preserving intellectual and volitive capacities to plan and carry out suicide; And younger age at dementia diagnosis, with higher difficulties in adjusting to the diagnosis.

We are moving towards pre-symptomatic and early dementia diagnosis utilizing biomarkers and genetic tests. This implies that the diagnosis is made in younger people, so concerns have been raised about a potential increase for suicidal behavior.

The findings of this research highlight the importance of providing support and paying attention to people with recent dementia diagnosis, particularly in the first year and for patients aged < 75 years. We suggest active management of pre-existing mental disorders, suicide risk evaluation, assessment of patient and caregiver needs and restricting access to lethal means.
