This paper is dedicated to the study of abuse of elderly people with dementia. Abuse is a serious social problem that manifests itself in many forms, such as physical, economic, sexual and psychological, but also through other forms, and dementia is a serious syndrome of progressive brain disease. The aim of this paper is to highlight the problem of abuse of elderly people suffering from dementia, to present its various manifestations, as well as to present dementia and to present the consequences of this abuse. It is important to show abuse through various theories and researches, and to explain the reciprocity of this relationship and gain insight into the various risk factors and ways of preventing the occurrence of abuse of older people with dementia and to gain insight into legal protection. This area is problematic and poorly researched as it is at the same time one of the most difficult to prove and least investigated abuse. Although the awareness of society about the seriousness and consequences of abuse of elderly people suffering from dementia has increased recently, in order to prevent and reduce the occurrence of dementia more successfully in the future, further efforts are needed to develop quality prevention and education programs, improve the legislative framework and work of various institutions that seek to prevent the occurrence of this abuse and expand research into this type of violence.
