Review Questions

• How does dementia impact an individual's ability to manage their nutrition and daily living activities?
  • Dementia affects an individual's cognitive functions such as memory, problem-solving, and decision-making. This decline can make it challenging for them to plan meals, shop for groceries, or prepare food, leading to nutritional deficiencies. Caregivers often need to assist with these tasks to ensure that the person with dementia receives adequate nourishment and maintains their health.
• What are some effective nutrition interventions for individuals diagnosed with dementia?
  • Effective nutrition interventions for individuals with dementia include providing structured meal times, offering easy-to-prepare meals that are rich in nutrients, and modifying food textures to accommodate chewing difficulties. Additionally, encouraging social dining experiences can enhance appetite and enjoyment of food. Nutritional assessments and individualized meal plans can also help address specific needs related to cognitive decline.
• Evaluate the relationship between malnutrition and the progression of dementia symptoms in elderly patients.
  • Malnutrition can exacerbate the symptoms of dementia by negatively impacting overall health and cognitive function. A poor diet may lead to deficiencies in essential nutrients that support brain health, potentially accelerating cognitive decline. Furthermore, individuals with dementia may struggle to maintain proper nutrition due to their cognitive impairments, creating a vicious cycle where worsening health further complicates their ability to manage their condition effectively.
