Introduction & Problem Statement

Maintaining a healthy and balanced diet is essential at every stage of life, but it takes on even greater significance as we age. For our elderly population, proper nutrition becomes a vital cornerstone of well-being, impacting both the quality of life and overall health. As we age, our nutritional needs change, and we need to pay special attention to the foods we consume. However even a well-balanced diet can be insufficient in case of improper food intake.

In our elderly population forgetfulness, and diseases like Alzheimer's or Dementia can really impact proper food intake. This could for example lead to skipping these essential meals, or conversely eating to much as a consequence of forgetting that one has eaten before.

The device we will be developing will be one that reminds the our elders by monitoring their food intake, when it is necessary to eat, and when this is not the case, ensuring that the individual will eat their meals regularly, ensuring proper food intake.

Users

User Profile

In this section, we will provide a detailed profile of the users of the our monitoring device. Understanding needs, and challenges of our target users is essential for designing our device.

1. Demographics

• Age: The typical age range of people with Alzheimer's disease who will use our device varies but is generally older adults. The primary users are typically aged 65 and older.
• Gender: Alzheimer's disease affects both males and females, with no gender-specific considerations impacting device usage.

2. Medical Condition

• Alzheimer's disease: Users of the device are likely to have varying stages and severities of Alzheimer's disease. Some users may be in the early stages, coping with mild cognitive impairment, while others may be in the later stages with severe cognitive handicaps. Common symptoms include memory loss, confusion, disorientation, difficulty with decision-making, and reduced motor functions. Challenges include medication management, food intake, and recognizing the need for medical attention.

3. Cognitive Abilities

• Cognitive impairment: The extent of cognitive impairment in our user group can range from mild to severe. Many users will experience difficulty in understanding and operating complex devices. Therefore the device should be simple, work with clear visual cues, and need minimal user input so that the device can be used effectively.
• Memory loss: Memory loss is a common symptom of Alzheimer's disease. Users may have difficulty recalling recent events, which can impact their ability to remember device usage instructions and data generated by the device.

4. Caregiver

• Involvement of caregivers: Caregivers play a vital role in assisting users with Alzheimer's disease. They may be responsible for device setup, maintenance, and interpretation of data. The device should have features that facilitate caregiver involvement while respecting the user's privacy.
• Caregiver characteristics: Caregivers may have varying levels of experience and qualifications. Some may be family members, while others may be healthcare professionals. Designing the device to support different caregiver backgrounds and abilities is important.

5. Daily Activities

• Daily Routine: Users often follow predictable routines, and the device should easily integrate into their daily activities. This may include reminders for meals, medication, and other daily tasks.

1. Natural history of hyperphagia and other eating changes in dementia https://pubmed.ncbi.nlm.nih.gov/9818306/ The text discusses various dietary changes and challenges experienced by individuals with Alzheimer's or dementia. These changes include alterations in eating habits, malnutrition, dehydration, and a range of eating behavior disorders. Some individuals may show a decrease or increase in the amount eaten, changes in eating habits, food choice preferences (particularly for sweet foods), and even hyperphagia (excessive eating). Hyperphagia can lead to issues such as weight gain, eating dangerous foods, and constant food seeking. The article highlights the significance of these eating abnormalities, which can be a significant source of stress for caregivers and may lead to the need for institutional care. Weight loss is also a common concern among individuals with dementia and is associated with protein-energy malnutrition, increased mortality risk, morbidity, and a poor quality of life. Weight loss can start early in the disease's course and is related to cognitive decline. Additionally, the text mentions that certain factors, such as the severity of the disease and the emotional and material burden on family caregivers, can predict aversive eating behaviors in Alzheimer's disease. Sweet food preference and hyperphagia have been reported in a subset of patients with Alzheimer's disease.

2. Weight Loss and Nutritional Considerations in Alzheimer Disease: https://www.tandfonline.com/doi/full/10.1080/01639360802265939 This paper discusses some of the current methods of feeding assistance for people with Alzheimer's disease. These are: Caregiver Assistance: Caregivers can provide assistance during mealtime, such as sitting and chatting with the patient, giving specific instructions, and offering encouragement. In later stages, patients may have coordination difficulties, so serving finger foods can make eating easier. This approach has been shown to increase food intake. Texture Modification: As patients deteriorate, some may become intolerant of certain textures, so menu items may need to be prepared in softer or pureed forms to facilitate consumption. Meal Environment: Simplifying the mealtime environment, such as improving lighting, serving meals on individual plates, and scheduling nursing staff to assist during mealtimes, can improve food consumption and nutritional status. Nutritional Supplementation: This includes providing frequent snacks, fortified foods, and liquid supplements. Studies have shown that protein-energy supplementation can lead to weight gain and reduced mortality in undernourished individuals. Pharmacologic Agents: Some medications have been used to improve appetite or cause weight gain in patients with weight loss. However, their use is limited due to side effects, and further study is needed before clinical recommendations can be made. Tube Feeding: In cases where other interventions fail and patients have severe dementia, tube feeding may be considered. However, there is limited evidence to support its benefits, and it may increase the risk of infection and aspiration pneumonia.

3. Assessment of Perceived Attractiveness, Usability, and Societal Impact of a Multimodal Robotic Assistant for Aging Patients With Memory Impairments https://www.frontiersin.org/articles/10.3389/fneur.2018.00392/full

This study aims to assess the clinical application of a robotic assistant for patients with mild cognitive impairments (MCI) and Alzheimer's Disease. Testing was conducted with the prototype version of the Robotic Assistant for MCI Patients at Home (RAMCIP) in a controlled environment, involving 18 elderly participants (10 healthy and 8 with MCI). Participants performed various tasks facilitated by RAMCIP, such as medication intake, hazard prevention, and social interaction. No significant differences were observed between the groups in terms of perceived attractiveness, usability, or social impact, with high assessments for attractiveness and social impact but neutral feedback on usability due to the limited interaction time. The study emphasizes the increasing need for support for the aging population, particularly those experiencing memory impairments. It highlights the potential role of robotic assistants in aiding caregivers and enhancing the independence and security of elderly individuals. The research methodology follows a user-centric approach, involving medical professionals, caregivers, and end-users in the evaluation process. The robot's design and functionalities have been adjusted based on user feedback. The RAMCIP prototype offers support in various aspects, including reacting to potential hazards, assisting with cooking, monitoring medication intake, providing cognitive stimulation, and maintaining social connections through multimodal communication. The study focuses on assessing the acceptability, usability, and social impact of the RAMCIP prototype among users. Standardized questionnaires and surveys are used for evaluation, with positive results in terms of acceptance and social impact, but neutral opinions on usability. In summary, this study evaluates the clinical application of a robotic assistant for individuals with cognitive impairments, emphasizing user perception and social impact, and aims to improve the robot's usability and acceptance among the target population.

4.The efficacy of cognitive prosthetic technology for people with memory impairments: A systematic review and meta-analysis: https://www.tandfonline.com/doi/full/10.1080/09602011.2013.825632?casa_token=3yNGLg1Wqd4AAAAA%3AcfO7AmhJ9zXNS6iFK5rAJcrLG4CZOseK41noZwEuBgJ4snmFNtoBHPT4ZVGjo9rI_vwQWfZ_HAo The purpose of this paper was to provide a detailed review of the quality of studies that have investigated memory orthotic technology with people with memory problems and to relate these findings to the different categories of technology. Studies testing cognitive orthotic devices with adults with any brain injury, trauma or neurological/degenerative disease. The NeuroPage has been highlighted in previous reviews as being the technology with the most evidence for its efficacy. Combining portable and non-portable PDA’s has excellent prospects for patients with memory impairment due to surgeries. However, in the case of degenerate diseases, such as Alzheimer’s, the benefits have still to be researched. Furthermore Future research should aim to establish whether or not there is a benefit to using technology instead of non-technological reminders, such as calendars.

Easily accessible and cheap smartphones are also a promising development in supporting patient with memory impairment. Touchscreen makes it more accessible for elderly users instead of a device with buttons. Also smartphones or portable tablets have the advantage that they are highly adaptable to personal preferences. On the other hand, using a smartphone or tablet device as a reminder may be less effective because of the number of different functions it provides and because they will not always be within the vicinity of the user.

Micro-prompting devices another promising development in memory impairment help. The details of the devices is not discussed in the paper (find other source for micro prompting devices in SCED studies). While prospective prompting devices and micro-prompting devices differ in the type of memory performance they are designed to aid, these findings suggest that if applied correctly both could be useful for memory impaired patients.
