Behavioral Characteristics of Bowel Movement and Urination Needs in Patients With Dementia in Taiwan

Patients with dementia, especially those with advanced dementia, may not be able to express their bowel movement and urination needs using lucid language, and instead do so through behaviors. The aim of the current study was to understand and compare the behavioral characteristics of bowel movement and urination needs in patients with dementia. Observations were made by caregivers of 187 patients with dementia based on the Behavior Checklist developed by the research team for bowel movement and urination. Sixteen behavioral characteristics were identified for both bowel movement and urination; among these, anxiety, taking off/putting on clothes inappropriately, restlessness, attempting to go elsewhere, scratching skin, repeated behavior, and making strange sounds were commonly reported. Facial expressions of sorrow, restlessness, and anxiety were the three most common behaviors related to bowel movement needs, whereas anxiety, taking off/putting on clothes inappropriately, and constant moaning were the most common behaviors for urination needs. The findings suggest that the common behavioral characteristics could be seen as indicators of excretion need and the others can be used to distinguish between the need for bowel movement and urination.
