Dementia causes many changes in people's lives. This includes changes to sex and intimate relationships (relationships that involve romantic and physical involvement). Often these changes can be difficult to discuss. This page explains how dementia can affect the sexual feelings, desires and needs of people with dementia and their partners. It outlines some of the ways in which sexual behaviour can change and suggests some ways for partners to deal with these changes. It highlights some practical issues, and discusses forming new relationships and issues around consent.
