The acceptance and ethics behind therapeutic lying (TL) as a non-pharmacological intervention for behavioral and psychological symptoms of dementia (BPSD) among persons with dementia continues to generate heated debates. This article presents a discussion of the ethical and cultural challenges on the perception of TL by people with dementia, their families, and health care professionals. Additionally, decision-making before TL was analyzed, including the types of TL, its efficacy and implications, alternatives to TL, and the ethical principles behind it. The results from this analysis show that TL is a common practice for BPSD. Its benefits include the reduction of these symptoms as well as the use of physical or chemical restraints. However, there is no consensus on its suitability as an approach, nor on the appropriate way it should be used. More experimental studies are needed to create legal and clinical intervention protocols that respect the fundamental rights of people with dementia promoting coherence, good ethical practices, and guidelines for person-centered care.
