Towards defining restlessness in individuals with dementia.

Area of Science:

• Gerontology
• Neuroscience
• Behavioral Science

Background:

• Behavioral problems are common in dementia, with restlessness being a significant concern for caregivers.
• Current definitions and measures of restlessness lack clarity, hindering research and intervention development.
• Understanding restlessness is crucial for improving the quality of life for individuals with dementia and their caregivers.

Purpose of the Study:

• To systematically define restlessness in dementia.
• To identify common elements across existing definitions and measures of restlessness.
• To differentiate restlessness from other behavioral symptoms and conditions.

Main Methods:

• Literature review of existing definitions and measures of restlessness.
• Identification of common elements and theoretical frameworks.
• Exploratory analysis of restlessness in 272 community-dwelling persons with dementia.

Main Results:

• Twenty-five scales for restlessness were identified, with shared components including motor, psychiatric, and needs-based features.
• Restlessness may co-occur with argumentation, anxiety, waking caregivers, delusions/hallucinations, and wandering.
• A proposed definition of restlessness includes diffuse motor activity, non-productive behavior, and subjective distress.

Conclusions:

• Restlessness is a distinct behavioral symptom in dementia with overlapping but non-equivalent features to other behaviors.
• A proposed three-attribute definition can enhance the understanding and reporting of restlessness.
• Clarifying restlessness manifestations will aid in tailoring interventions for this complex behavioral type.
