Conceptual Foundations and Clinical Characteristics of Dementia
The topic chosen for this project is an older person with dementia disease.
Clinical Definition, Etiology, and Symptomatology of Dementia
When an individual loses their thinking, memory, and reasoning abilities to the point where the loss interferes with day-to-day tasks, this condition is known as dementia. Some dementia patients have emotional instability and personality changes. The intensity of dementia varies from the mildest level, when it is just starting to interfere with a person's ability to function effectively, to the most severe level, when the individual must fully rely on other people for fundamental daily activities. As people grow older, dementia becomes more prevalent, yet it is not a specific aspect of aging (National Institute on Aging, 2021). Approximately one-third of all adults over 85 could have some dementia. Many people get to their nineties without displaying any dementia symptoms. There are different types of dementia, including Alzheimer's disease, vascular dementia, frontotemporal dementia, and Lewy body dementia. People with different forms of dementia may indicate varying signs and symptoms depending on the type of dementia they have.
When nerve cells, or neurotransmitters in the brain that were once healthy, cease functioning, lose their links with other brain cells, and eventually die, dementia manifestations and signs develop. While everybody loses some neurons as they age, dementia patients lose many more neurons. Loss of memory, poor decisions, uncertainty, speech difficulties, comprehending and articulating one's thoughts, difficulty writing and reading, roaming and getting lost in a local area, and difficulty managing money properly and paying bills are just a few of the symptoms of dementia that might vary (National Institute on Aging, 2021). In addition, asking inquiries more than once, referring to familiar objects with strange words, taking long to finish daily activities, and getting bored with regular daily activities or occurrences are other symptoms of dementia. Patients suffering from delusions or anxiety experience hallucinations, have impulsive actions, and usually disregard the feelings of others. The etiology of Alzheimer's and other forms of dementia can differ based on the kinds of possible cognitive changes. While studies have revealed some brain abnormalities related to specific types of dementia, the root causes are frequently unknown. A small percentage of persons may develop dementia due to rare genetic abnormalities (Livingston et al., 2020). Some risk factors for dementia include inadequate training, high blood pressure, hearing loss, smoking, being overweight, anxiety, lack of exercise, diabetes, minimal social contact, alcoholism, traumatic brain injuries, and environmental pollution.
Furthermore, physicians first determine whether a patient has an inherent, possibly curable disease connected to cognitive impairments before diagnosing dementia—blood tests to examine levels of different chemicals, enzymes, and micronutrients in blood and other fluids. Physical examinations to assess hypertension and other vital signs can help identify or check out potential causes of dementia symptoms. Reviewing a person's family and medical background can offer crucial hints regarding the risk of dementia (National Institute on Aging, 2021). Physicians diagnosing patients with dementia may ask them several questions, including inquiring whether the disease exists in the family line, when and how indications started, changes in attitudes and personality, and whether the patient is taking any drugs that could cause or exacerbate symptoms. In addition, certain prevention measures may reduce the risk of dementia among patients suffering from the disease (Livingston et al., 2020). These measures may entail treating hearing problems, regular physical exercises, treating hypertension, stopping smoking, reducing excessive alcohol, treating diabetes, preventing head injuries, and reducing air pollution. When patients put these measures into practice, they can reduce the intensity of dementia in their lives and regulate its effects.
Epidemiological Trends and Global Burden of Dementia
In Ireland, there are currently 64,142 individuals who have dementia. As age is the primary risk factor for developing dementia, this proportion is anticipated to increase to 150,131 by 2045 as the population grows (Dementia Pathways, 2022). Every year, 11,000 new instances of dementia are recorded. In Ireland in 2018, dementia was ranked as the fourth leading cause of mortality. Dementia is thought to cost 1.69 billion Euros annually. In Ireland, there are approximately 60,000 family carers and 35,736 dementia patients in the community, and 72% of persons in long-term care facilities are anticipated to have dementia (DSIDC, 2022). In addition, a rising body of research from Europe and North America indicates a declining trend in dementia prevalence, possibly due to advancements in the control of cardiovascular disease and related risk factors as well as advancements in educational achievement. Given that age-specific prevalence has been found to grow in Japan and China, it is unknown if these tendencies will persist into the future or if they will spread to other regions (Nichols et al., 2022).
Nevertheless, all projections concur that dementia will cause a significant rise in the overall population over time. From 1990 to 2016, the global rise in dementia cases was 117%, mostly due to population aging. According to demographic assessments, these patterns are caused by declining fertility and rising lifespan, resulting in significant adjustments in the population's age distribution. The prevalence of dementia has increased significantly due to these modifications, growing populations, and generally steady age-specific prevalence statistics (Nichols et al., 2022). Dementia has been a leading cause of many deaths globally. There were 261,914 confirmed deaths in the United States in 2017, with dementia listed as one of the underlying causes. Alzheimer's illness was the underlying cause of 46 percent of these demises (Kramarow & Tejada-Vera, 2019).
Cultural and Ethical Dimensions in Dementia Diagnosis and Care
It has been proposed that common dementia screening methods may not be culturally suitable, resulting in inaccurate diagnoses. According to Alzheimer's Research UK, modern memory assessments relate results to averages for the predominantly white British population. In these societies, diagnosing dementia could be severely hampered by the tests' absence of culturally appropriate queries. Cultural considerations should be incorporated into all health-related and social examinations (Mason, 2022). Healthcare and social professionals should consider an individual's family, personal background, religious views, and perceptions toward health, illness, and care when deciding their needs and how they might be addressed.
In addition, there is an urgent need to create better, more efficient treatment plans for dementia, a worldwide public health problem. Nevertheless, the study of dementia presents special legal and ethical problems. Research on pharmaceutical and non-pharmacological therapies and observational studies must deal with securing consent from people with cognitive deficits, people from different cultural backgrounds, and people concerned about privacy and anonymity. Research on palliative care for dementia must address ethical dilemmas concerning participants in end-of-life studies (Chandra et al., 2021).
Comprehensive Care Needs of Older Adults Living with Dementia
Older people with dementia have various physical, emotional, and intellectual needs. Some of the physical needs of dementia patients include food, shelter, drinks, optimum body temperatures, and sexual needs. Shelter is one of the key elements that affect the quality of life for people with dementia, and many older people opt to stay in their homes as they receive help from caregivers. They can also go to residential or nursing homes where they can find the shelter they seek. In addition, dementia patients have eating challenges, which places them at risk of malnutrition. Therefore, there is a need for these patients to have access to nutritious and healthy food to help boost their health.
Dementia impacts the brain, and those with it may experience emotional and behavioral needs. Some of the emotional needs include encouragement, reassurance, and attention (Petty et al., 2020). In addition, the intellectual needs involve reading, playing games, jigsaw puzzles, and word searches, especially in the early stages, to maintain cognitive function (Takenoshita et al., 2020).
Care Planning and Adaptation Following Dementia Diagnosis
After the patient is diagnosed with dementia, certain changes and plans must be made. A care plan outlines the type of care and assistance required and how it will be delivered (GOV.UK., 2018). Identifying a care coordinator is also essential, as this person will act as the main point of contact. Additionally, caregivers should receive appropriate support and assessments if necessary.
Roles and Responsibilities within Multidisciplinary Dementia Care Teams
A healthcare assistant (HCA) plays a crucial role in supporting dementia patients by providing holistic care, assisting with daily tasks, and maintaining effective communication (Handley et al., 2019). They collaborate with nurses and physicians to ensure quality care delivery. The care setting also plays a vital role by providing a safe and supportive environment for both patients and healthcare professionals.
Other healthcare professionals contribute by managing medications, developing care plans, addressing behavioral issues, and ensuring patient safety (Deshaies, 2022).
Innovative Support Services and Interventions for Enhancing Dementia Care Quality
Telehealth is one strategy that supports patients and caregivers through remote consultations and monitoring (National Institute on Aging, 2020). Social groups and educational activities also enhance patient engagement and improve quality of care by promoting interaction and mental stimulation.
End-of-Life Care Strategies and Compassionate Patient Engagement
Care at the end of life for dementia patients should focus on comfort, dignity, and quality of life (Bartley et al., 2018). Palliative care helps reduce suffering and improve well-being (Eisenmann et al., 2020). Gathering information should be conducted sensitively through medical assessments and reviewing patient history.
Health promotion initiatives include effective communication, maintaining relationships, and ensuring that patients feel heard and supported (Odzakovic et al., 2021).
