Which factor can negatively affect appetite in elderly patients?

Cognitive decline is a significant factor that can negatively affect appetite in elderly patients. As individuals age, cognitive issues such as dementia or other forms of cognitive impairment can interfere with their ability to recognize hunger cues, plan meals, or even remember to eat. This decline can lead to decreased motivation to prepare food or to eat, ultimately resulting in poor nutrition and potential weight loss.

While increased physical activity and high social engagement typically enhance appetite by stimulating hunger and encouraging social meals, these factors can also help maintain a healthier lifestyle. Access to meals usually supports proper nutrition and appetite, making it an unlikely contributor to appetite decline. Thus, cognitive decline stands out as a key factor hindering the elderly's appetite, showcasing the complex interactions between mental health and nutrition in this population.
