Alzheimer’s Lack Of Appetite

Herbal Medicine For The Treatment Of Appetite Loss In Dementia

There are several causes of appetite loss. Although there is no specific medicine against appetite loss, several medications, such as antipsychotic drugs, are expected to have an appetite-improving effect. It has been reported that ghrelin and olanzapine successfully increased appetite. While most anti-dementia drugs may cause a loss of appetite as a side effect, it is reported that rivastigmine may have an appetite-enhancing effect .

Some herbal medicines are also shown to improve appetite and mood. Of these, rikkunshito, hochuekkito, and ninjin’yoeito are often selected for elderly people, especially those with suspected frailty. Citrus unshiu peel and glycyrrhiza, which are crude drug components of herbal medicine, are included in both these drugs. Hesperidin, nobiletin , and isoliquiritigenin are reported to increase and restore secretion of ghrelin . In addition to improving appetite, these herbal medicines may be expected to impact cognitive function. It was suggested that ginseng, hesperidin, and narirutin inhibit amyloid aggregation and improve learning and memory function . In addition, tenuigenin, the main component of polygalae radic, has been shown to promote the proliferation and differentiation of hippocampal neural stem cells. BT-11, an extract from polygalae radic, is reported to improve cognitive function in older adults, and is also licensed as a dietary supplement .

The Plate Colour Matters

In a study conducted at Boston University, researchers found that patients eating from red plates consumed 25 percent more food than those eating from white plates. This appears to be connected with the way someone living with dementia sees food on a plate. If you cant really see food because its on a white background you are much less likely to eat it.

The use of colour helps to stimulate interest in dementia patents, as often they have trouble distinguishing between colour. If the food is too close to the colour palette of the plate, people with dementia can struggle to distinguish the contrast between the two and realise there is food to be eaten.

A company called Eatwell Tableware have a fantastic selection of innovative tablewear designed for those with dementia or motor impairment.

How Seniors Express A Lack Of Appetite

Your loved one may express a lack of appetite in different ways. For instance, he or she may start to refuse meals, or you may notice that he or she is suddenly losing weight without any other obvious cause. If your loved one faces speech difficulties, he or she may use nonverbal cues such as pushing the plate away or getting angry at mealtimes. Seniors with dementia-related appetite loss may also prefer only certain types of foods, such as those that are extremely sweet or salty. All other types of food may be left on the plate.

Some seniors require assistance in preparing their favorite meals every day, while others simply need someone to spend time with at mealtimes. Not every senior has the same care needs, which means they dont all need the samehomecare services. Huntsville families can rely on Home Care Assistance to provide individualized care plans to meet your elderly loved ones unique care needs. Our holistic Balanced Care Method was designed to help seniors focus on healthy lifestyle habits such as eating nutritious foods, exercising regularly, and maintaining strong social ties, and our Cognitive Therapeutics Method offers mentally stimulating activities that can stave off cognitive decline and delay the onset of dementia.

Practical Tips To Help Someone With Dementia To Eat More

People living with Alzheimers or dementia often eat less than they used to. This can be due to medical problems associated with chewing, swallowing or digesting food.

Sometimes people just lose interest in food. This can happen for a long list of reasons including loss of taste, the ability to smell, memory loss, and thinking they have already eaten. Certain medications can also affect appetite.

The ability and want to eat tends to get worse as the disease progresses and ensuring someone living with dementia eats a nutritious meal, or eats enough, can become a real practical and emotional issue for the carer. We have compiled a list here of 8 practical tips for helping someone with dementia to eat more.

Assessment Of Eating Behaviour

A questionnaire was designed on the basis of review of published reports and our previous clinical experience of the eating and swallowing behaviours commonly reported in frontotemporal dementia groups and Alzheimers disease. After piloting of six prototypes, the final version of the questionnaire consisted of 36 questions investigating the following five domains: swallowing problems, appetite change, food preference , eating habits , and other oral behaviours . The questionnaire is available from the authors or the Journal Web site.

Table 2

Frequency of abnormal eating behaviours in frontotemporal dementia, frontal variant , semantic dementia , and Alzheimers disease

Information was gathered from a caregiver familiar with the patients eating behaviour. It was emphasised that a symptom should reflect a substantive change from patients premorbid state and not a longstanding character trait. If caregivers indicated that abnormal behaviour was present, they were asked to rate the frequency , severity , and beginning date of behaviour. For each abnormal behaviour, we derived a product of frequency times severity in keeping with the method applied in the Neuropsychiatric Inventory. Caregivers were also asked to estimate the number of pounds lost or gained to compare the weight before illness.

Dementia & Alzheimer’s Disease

For a person with dementia, the topic of dementia and eating is important to discuss.

This is because individuals with dementia usually go through several changes one of them being how they eat.

Below you will explore some of the common eating challenges persons with dementia face.

It is important to understand each to act accordingly.

Weight Loss And Change In Body Composition Among Patients With Cognitive Impairment

Nutritional problems, notably body weight loss, are frequently seen among those with AD from early-stage, however, the detailed mechanisms are not fully understood. A recent review suggests that weight loss among patients with dementia is caused by a decrease in energy intake due to loss of appetite as well as by an increase in energy expenditure due to increased basal metabolism and behavioral disturbance . It has also been reported that skeletal muscle is reduced in early-stage AD, and skeletal muscle mass is associated with brain volume and severity of cognitive impairment . Additionally, with the progression of dementia, fat mass is also reduced in patients with dementia , while fat mass is generally increased or unchanged in healthy older adults with aging . These previous studies indicate a significant link between changes in body composition and cognitive deterioration. Further studies are needed to investigate the natural history and impact of changes in body composition among patients with cognitive impairment.

Why Do People With Dementia Lose Weight

While there are many contributing factors, the cognitive and behavioral changes, hormone dysregulation and sensory dysfunction in the body and brain all converge to disrupt appetite, leading to weight loss in people with dementia.

Various reasons for weight loss in people with Alzheimers disease and dementia include:

The cascading effect of progressive brain disease can alter the nervous and endocrine systems as well as other essential functions of the body, including those that impact taste and other senses.

Eating And Drinking For A Person With Dementia

Dementia often has an impact on peoples appetite and ability to eat and drink. Read our advice on some of the changes you might notice and how to support the person you care for.

People with dementia may experience problems with eating and drinking, and its quite common for their appetite to change as their condition progresses.

They might:

• forget to eat or drink
• not recognise when they are hungry, thirsty or full
• have trouble preparing food or drinks
• struggle to recognise food items
• have a change in appetite or taste
• find certain colours, textures or smells of food off-putting
• struggle to follow particular diets, for example for diabetes, coeliac disease, or religious or cultural diets
• have difficulty handling cutlery and feeding themselves
• find it difficult to swallow
• develop a sweet tooth

Helping a person with dementia to maintain a healthy diet can be difficult, but its important to encourage them to eat well. You could try:

A person with dementia may not always be able to recognise when they are thirsty, or communicate their thirst. This means it can be difficult for them to drink the recommended eight to 10 glasses or mugs of fluid per day. You could try:

• making sure the person always has a drink beside them
• offering squash if they dislike water
• offering a choice of hot and cold drinks
• helping if they are struggling to pick up or hold a cup
• offering different shapes and sizes of cup
• using a favourite mug, glass or cup, if they have one

Besides The Presence Of Other Health Problems And Medication Side Effects Are There Other Reasons Persons With Alzheimers Disease Lose Weight

Other reasons for weight loss in persons with Alzheimers disease include:

• More calories being burned. Individuals with Alzheimers disease may lose weight because they may burn more calories than elderly people without the disease. People with dementia frequently pace, wander, and are more likely to be in motion activities that burn more calories.
• The effects of Alzheimers disease itself and aging. Food preferences may change as dementia progresses. Favorite foods may no longer be favorites. Certain food types may become more desired . Vision or sense of smell or taste may become impaired, which makes finding the food and stimulating the appetite more difficult. If the individual with Alzheimers disease is delusional, they may not eat because they fear something, hear voices, or may be distracted during dining and leave the table before finishing the meal. People with advanced Alzheimers disease may lose the ability to recognize foods or forget how to use utensils to bring food into the mouth even though they may be hungry. They can also forget how to chew and swallow food. In addition, patients can also lose weight if they can no longer communicate health problems that are making it less desirable to eat, such as gastrointestinal pain and discomfort.

Other events in the lives of the elderly, such as grief and mourning the loss of a spouse or life-long friends as well as social isolation, can also lead to weight loss.

Initial Causes Alzheimers And Lack Of Appetite

There are several different causes of memory loss. Some cause this condition in the young, while others may be more gradual. If you notice that your memory is weakening, its important to consult a medical professional. Whether the cause is mental illness, age, or a combination of factors, its important to seek treatment as soon as possible. People with extensive memory loss may have social difficulties and anxiety, which can lead to depression. They may be afraid they are letting their loved ones down, which can lead to anxiety and depression. Alzheimers and Lack of Appetite

Fortunately, there are many causes of memory loss, and many of them are treatable. However, if you are experiencing serious memory problems, you may need medical treatment. If you have been undergoing any type of medication, you should consult with your doctor. Some people have other underlying conditions that may be causing their loss of memory. Alcohol abuse, sleep deprivation, or other mental health conditions can cause memory problems. You should seek out a medical professional if you suspect youre suffering from any of these conditions.

Here are some of the best ways to make your brain healthier and keep your mind sharp. Read on to learn more. Alzheimers and Lack of Appetite

Sensory Dysfunction Caused By Dementia

Vision, for instance, serves an important role in reducing weight loss. As early as 2004, researchers from Boston University correlated the level of food intake to visual-cognitive deficiencies in people with dementia. The breakthrough findings from the red plate study led to the introduction of brightly colored flatware and other products that use color to assist with eating.

The red plate study findings suggested that people with Alzheimers disease will eat 25% more food on a red plate than on a white plate!

Modifications to the environment, meal preparation and delivery are also used to increase appetite and reduce weight loss caused by dementia.

Dementia can interfere with the human sensory system in various ways:

Dementia caregivers often find it necessary to adapt food choices and eating strategies to meet a persons changing needs, preferences and abilities and offer higher calorie items more frequently to help them maintain a healthy weight.

While there is still much to learn about the relationship between Alzheimers disease and weight loss, leading memory care communities incorporate the latest science and research into innovative dining programs for better nutritional outcomes.

For example, Bravo Dining by Serenades Memory Care helps residents maintain a healthy weight by engaging all five senses.

Factors Associated With Sarcopenia In Mci And Early

In this study, sarcopenia was shown to be independently associated with appetite, in addition to low BMI and polypharmacy that were shown to be associated with sarcopenia in previous studies.

Besides appetite loss, feeling full, and food tastes compared to when younger were associated with sarcopenia. Usually, the onset of satiety represents a response to neural and endocrine factors, such as gastric distension and release of the gut peptide cholecystokinin that are generated during the course of meal ingestion . A previous study reported that 28.3 and 27.3% of mild AD patients experienced reduced and increased appetite . While the causes of reduced and increased appetite in patients with AD remains unclear, a change in satiety responsiveness may affect their appetite . Further studies are needed to clarify changes in satiety among those with dementia.

Gustatory function changes with aging . In dementia, some studies reported that the recognition thresholds of the four elements of taste, i.e., sweet, salty, sour, and bitter, are higher in patients with MCI and AD than in healthy subjects . In contrast, there is also a study reporting that demented patients and healthy elderly people are similar in gustatory function . Given that there are very few studies that focused on gustatory function in patients with dementia, however, patients with dementia require to be further evaluated for changes in gustatory function in future studies.

Taste And Smell Changes

Significant deficits in the perception of taste preferences, quality, and intensity are caused by peripheral loss of taste/smell receptors or neurons. Olfactory deficits occur in the ageing progress alone but also early on in dementia. Apolipoprotein E is a polymorphism associated with an increased risk of developing AD. Individuals carrying the APOE4 allele seem more prone to suffer from impaired olfactory function before the onset of cognitive impairment.8 To date, studies have shown inconsistent findings on the olfactory profiles for each type of dementia.9 Olfactory dysfunction can be used as a pre-clinical biomarker for dementia and olfactory testing may become a supplementary tool in early detection of dementia.10 People living with dementia were found to have a strong preference for sweeter foods and carbohydrate over protein and fat.11

Malnutrition Among Alzheimers Patients

Nutritional problems are associated with adverse outcomes, such as rapid cognitive decline, explain Kimura and colleagues. Appetite changes, weight loss, and sarcopenia can begin even with mild cognitive impairment and early-stage Alzheimers. Their analysis shows that 54% of patients are at risk of malnutrition in the early stage of Alzheimers, and another 8% are already malnourished. Those same patients show a higher rate of behavioral symptoms, such as aggressive behavior, emotional disinhibition, and apathy.

They also cite research indicating that some neuropsychiatric symptoms, such as hallucinations and nighttime disturbances, are more severe in the presence of malnutrition.

Nutritional status is important to quality of living and progression of the illness, according to Kimura et al. Nutritional problems appear to be important, albeit modifiable, factors that may affect the prognosis of dementia, they note. Even in early stages, they say, some research indicates that low body mass index predicts progression of MCI to dementia.

Nutritional Screening And Assessment

People living with dementia are more vulnerable to developing malnutrition which can be preventable with early detection and intervention. Therefore, nutritional screening and assessment should be integral for all people with dementia in line with National Institute for Health and Care Excellence guidance.17 The Malnutrition Universal Screening Tool 18 or Mini Nutritional Assessment19 are common screening tools suitable for detecting malnutrition risk. The Global Leadership Initiative on Malnutrition criteria is for diagnosis of malnutrition and it recommends BMI 22kg/m2 as the lower BMI cut-off for adults over 70 years.20
