[Abnormal eating behaviors in elderly people]

Area of Science:

• Gerontology
• Neuroscience
• Nutritional Science

Context:

• Olfactory function naturally declines with age, impacting sensory perception in the elderly.
• Dementia presents with varied eating and swallowing challenges, specific to dementia subtypes.
• Altered food preferences and eating behaviors are common in older adults and dementia patients.

Purpose:

• To explore the relationship between age-related olfactory changes and eating behaviors.
• To investigate the diverse eating and swallowing difficulties in patients with different types of dementia.
• To highlight the importance of considering these changes in dementia patient care.

Summary:

• Healthy elderly individuals often experience impaired olfaction compared to younger adults, potentially affecting food choices.
• Dementia patients exhibit distinct eating patterns: Alzheimer's type dementia is associated with olfaction impairment, dementia with Lewy bodies with swallowing problems, and frontotemporal dementia with binge eating.
• These specific eating and sensory changes must be recognized for effective patient management and care.

Impact:

• Provides insights into sensory changes affecting nutrition in the elderly and dementia patients.
• Emphasizes the need for personalized dietary and care strategies based on dementia type.
• Informs healthcare professionals and caregivers about managing eating-related issues in dementia care.
