[The so-called hypersexual behaviors in dementia].

Real hypersexuality is rare in demented subjects. Most inappropriate sexual behaviors are related to disinhibition or lack of taking into account contextual environment and feelings of others. Four dimensions should be taken into account for their analysis: research of intimacy, libido enhancement, disinhibition, and cognitive factors. An integrative model is proposed to adequately adapt their management, using both psychocomportemental and pharmacological approaches.
