Sexual disinhibition and dementia

Area of Science:

• Neuroscience
• Gerontology
• Psychiatry

Background:

• Sexuality is a fundamental human need for intimacy.
• Cognitive decline in dementia can impair an individual's ability to express intimacy appropriately.
• Inappropriate sexual behavior (ISB) in dementia is a complex phenomenon influenced by biological, psychological, and environmental factors.

Purpose of the Study:

• To systematically describe the nature and characteristics of inappropriate sexual behavior (ISB) observed in patients with dementia.
• To explore the potential causes and contributing factors of ISB in the context of cognitive impairment.
• To differentiate types of ISB and their associations with dementia characteristics.

Main Methods:

• Comprehensive literature search of Cochrane Library, PubMed, and Web of Science from 1950 to 2014.
• Inclusion of relevant articles, chapters, and books using keywords: 'hypersexuality', 'inappropriate sexual behaviors', and 'dementia'.
• Review of identified publications for further relevant references.

Main Results:

• ISB in dementia can manifest as intimacy-seeking or disinhibited behaviors.
• These behaviors are associated with dementia type, severity, and potentially other concurrent disorders.
• While indifference is a common change, ISB can occur across dementia stages, notably in Alzheimer's and frontotemporal dementia.

Conclusions:

• ISB in dementia is a multifaceted issue requiring careful consideration of cognitive and behavioral changes.
• Non-pharmacological interventions are generally preferred for managing ISB due to potential limited response to psychoactive therapies.
• Effective management of ISB may not always be achieved solely through non-pharmacological approaches.
