HCAP 1220 Introduction to Dementia What is Dementia? Dementia is a progressive, chronic condition characterized by the deterioration of cognitive functions such as memory, thinking, reasoning, communication, and problem-solving, which interferes with a person's ability to perform daily activities. It is not a single disease but a group of illnesses, including Alzheimer’s disease, vascular dementia, Lewy body dementia, and frontotemporal dementia. Dementia is not a normal part of aging and often includes changes in behavior, mood, and personality. Early symptoms may include difficulty managing complex tasks, confusion, and memory lapses, while advanced stages involve significant challenges with basic self-care and communication. Compassionate care, understanding, and a person-centered approach are essential in supporting individuals with dementia and their families. Let’s break that down… 1 2 3 4 5 Definition and Progression: Not a Normal Part Types of Dementia: Impact: Dementia Characteristics: Dementia typically of Aging: Dementia The primary types significantly alters a Dementia is a term starts gradually, is not a natural of dementia include person’s for the progressive initially affecting consequence of Alzheimer’s disease, independence and loss of brain complex tasks like aging but a group of vascular dementia, quality of life as it functions, including driving, managing illnesses that dementia with Lewy worsens over time, cognitive, social, money, and require medical bodies, and fronto- necessitating and functional planning, before attention. temporal dementia. increasing levels of abilities.

History of Dementia In 1906 German psychiatrist and neuropathologist Dr. Alois Alzheimer provided the first detailed case study of what would later be called Alzheimer's disease. He had found the two distinguishing characteristics were (1) plaques, deposits in the brain that become toxic to brain cells at excessive levels, and (2) tangles, which interfere with vital processes and eventually choke off living cells. As a result, the brain physically shrinks as these brain cells die, and ultimately how the brain functions is affected. The nerve cells in the brain become sick and progressively less and less able to pass on messages to other nerve cells, and eventually these cells die. It is the loss of connectivity (the ability of one cell to communicate with another), which occurs long before the cells die, that is responsible for the symptomology. History Continued… Following Alzheimer's work, other researchers began to classify different forms of dementia, such as vascular dementia, frontotemporal dementia, and dementia with Lewy bodies. In the 1980s – 1990s development of neuroimaging technologies (e.g., CT scans, MRIs, and PET scans) allowed scientists to observe brain changes associated with dementia in living patients. In the 21st century researchers began focusing on lifestyle and environmental factors that contribute to dementia, emphasizing prevention strategies such as physical activity, diet, and cognitive engagement. Today’s Research Findings! Recent research has increasingly highlighted the potential role of the gut microbiome in the development and progression of dementia, particularly Alzheimer's disease. This emerging field of study suggests that alterations in gut bacteria may influence brain health through the gut- brain axis, a complex communication network linking the gastrointestinal tract and the central nervous system. Research indicates that gut bacteria can produce amyloid- like proteins, which might seed the formation of amyloid plaques in the brain—a hallmark of Alzheimer's disease. Additionally, amyloid deposits have been found in the intestinal tissues of individuals with Alzheimer's, suggesting a possible link between gut and brain amyloid pathology. Even more interesting… Experiments involving the transfer of gut microbiota from Alzheimer's patients to healthy animals have resulted in the recipients exhibiting Alzheimer's-like symptoms. This finding supports the idea that gut microbiota alterations could play a role in the disease. While these findings are compelling, it's important to note that the relationship between the gut microbiome and dementia is complex and not yet fully understood. Current evidence suggests that gut health may influence brain health, but it does not conclusively establish that dementia begins in the gut. Ongoing research aims to clarify these connections and explore potential therapeutic interventions targeting the gut microbiome to prevent or slow the progression of dementia. To diagnose the cause of dementia, a health care professional must recognize the pattern of loss of skills and function. The care professional also determines what the person is still able to do. More recently, biomarkers have become available to make a more accurate diagnosis of Alzheimer's disease. Brain scans: PET scans. These scans can show patterns of brain activity. They can determine whether amyloid or tau protein, hallmarks of Alzheimer's disease, have been deposited in the brain. Diagnosis of Lab Tests: Simple blood tests can detect physical problems that can affect brain function, such as too little vitamin B-12 in the body or an underactive Dementia thyroid gland. Psychiatric Evaluation: A doctor may ask about the patient's mood, sense of well-being, and relationships to determine if depression or another mental health condition is causing the patient's symptoms. There's no single test that can definitively diagnose dementia, so doctors use a combination of tests and other information to make a diagnosis. The process of diagnosing dementia can take time, and a doctor may need to perform additional tests to make a more certain diagnosis. Recognizing Patterns: HCAs play a key role in observing and reporting changes in a resident’s abilities and behavior. These observations help health care professionals identify patterns of skill and function loss that could indicate dementia. HCA Role in the Diagnosis of Lab Tests: HCAs may support residents during simple blood tests Dementia Psychiatric Evaluation: HCAs often interact closely with residents, offering insights into their mood, social interactions, and emotional well-being. These observations can assist doctors in assessing for depression or other mental health conditions contributing to symptoms. When it is diagnosed and the HCA Role When it is diagnosed, dementia is then categorized as either a mild or major neurocognitive disorder, depending on the extent of loss of cognitive and social functioning. Mild vs. Major Neurocognitive Disorders: HCAs should understand that dementia is classified as mild when individuals can still function independently with some assistance and as major when individuals require significant support with daily activities. This distinction helps HCAs provide appropriate levels of care. Role of Neurocognitive Decline: Neurocognitive disorders involve declines in areas such as attention, memory, problem-solving, language, and motor skills. HCAs should monitor and document changes in these areas to help health care teams assess the progression of dementia. Individualized Care Plans: Categorizing dementia as mild or major helps create tailored care plans. HCAs should understand that care strategies may shift as the disorder progresses, requiring adjustments in assistance with personal care, communication, and safety. Early Warning Signs (Symptoms) of Dementia Memory impairment that affects daily activities (e.g., misplacing items or putting them in odd places) Repeating words or sentences; difficulties finding the right words or following conversations Poor judgement (e.g., going outdoors in the snow without shoes) Difficulties with common tasks (e.g., dressing, cooking, driving) Changes in mood, behaviour, or personality (e.g., unfounded jealousy, suspiciousness, or poor social behaviour) Loss of interest in activities or hobbies (e.g., an avid gardener now letting weeds overrun the garden) Risk Factors Non-Modifiable Risk Factors: Age: Strongest risk factor; risk increases significantly after 60 Genetics: A family history of dementia increases risk. Gender: Women are at a higher risk of developing dementia than men. The reasons for this are not fully understood, but they are believed to involve both biological and social factors. Women generally live longer than men, so they are more likely to reach an age where dementia becomes more prevalent. Modifiable Risk Factors: Cardiovascular health: high blood pressure, high cholesterol and diabetes increase risk for specifically vascular dementia Lifestyle factors: sedentary lifestyle and lack of exercise. Poor diet, particularly one low in fruits, vegetables and whole grains Mental health: untreated depression or anxiety can increase risk. Social isolation and lack of cognitive stimulation. Brain injuries: history of concussions or severe head trauma Sleep disorders: conditions like sleep apnea may contribute to cognitive decline Environmental factors: exposure to toxins such as certain chemicals or heavy metals Chronic conditions: stress Preventative Strategies How HCAs Help Promoting a Healthy Lifestyle: Encourage Healthy Lifestyle: Balanced and assist clients in maintaining a balanced diet, regular physical activity, diet by preparing nutritious meals and and mental stimulation snacks. Support regular physical activity by engaging clients in safe exercises such as walking, stretching, or chair exercises. Facilitate mental stimulation through activities like puzzles, reading, or memory Chronic Disease Management: games. Control blood pressure, Assisting with Chronic Disease Management: diabetes, and cholesterol Support clients in following health recommendations, including diet plans for managing chronic illnesses. Fostering Social Engagement: Facilitate Social Engagement: Maintain opportunities for social interaction, such as strong social connections to group activities, community programs, or reduce cognitive decline family visits. Engage clients in conversations, group games, or shared hobbies to strengthen their sense of connection and reduce isolation. Mental Health Support: Treat Supporting Mental Health: Create a calm, depression, anxiety, and other supportive environment to reduce stress and anxiety. Encourage participation in relaxation psychological conditions techniques like deep breathing or mindfulness activities. No cure. Only medication can slow disease progression and manage symptoms Medications: Donepezil, Rivastigmine, Memantine, Leqembi Occupational therapy. An occupational therapist can show you how to make your home safer and teach coping behaviors. The purpose is to prevent accidents, such as falls. Establish a nighttime routine. Behavior is often worse at night. Try to establish going-to-bed routines. Aim for a calming routine away from the noise of television, meal cleanup and active family members. Leave night lights on in the bedroom, hall and bathroom to prevent disorientation. Keep a calendar. A calendar might help your loved one remember upcoming events, daily activities and medicine schedules. Consider sharing a calendar with your loved one. Alternative Medicine: Music therapy, which involves listening to soothing music. Pet therapy, which can include visits from dogs or other animals to promote improved mood and behavior. Aromatherapy and massage therapy, which uses fragrant plant oils. Art therapy, which involves creating art, focusing on the process rather than the outcome. Doll therapy in dementia care involves using dolls as comforting, therapeutic tools to help reduce anxiety, agitation, and emotional distress by providing a sense of purpose, companionship, and nurturing for individuals with dementia. Snoezelen therapy for dementia care provides a calming, multi-sensory environment using lights, sounds, textures, and scents to reduce agitation, enhance relaxation, and improve emotional well-being. Treatment & Therapies Stages of Dementia Three Stages of Dementia: Dementia is typically divided into three stages: early, middle, and late, which apply to Alzheimer’s disease and most other forms of dementia. Individual Variation: The progression of dementia varies widely. Symptoms, behaviors, and the order in which they appear depend on which areas of the brain are affected. No Clear Boundaries Between Stages: The transition between stages is gradual, with significant overlap. Symptoms may appear in a mixed manner, and the progression timeline is unique to each client. Fluctuations in Symptoms: Clients may experience day-to-day fluctuations in cognitive abilities and behavior, appearing more disoriented or confused on some days and less so on others. Rate of Decline Varies: The length and severity of each stage differ from client to client, influenced by individual factors such as overall health, type of dementia, and support systems. Clients with dementia are often cared for at home by a primary caregiver, usually a spouse, adult child, or family member, with support from friends, volunteers, and home care workers; respite care and community programs can provide temporary relief for caregivers. Clients with dementia need help staying organized, solving problems, and remembering tasks like appointments and medications. As a caregiver, ensure safety by supervising activities, creating a secure environment, and following Stage 1: Mild the care plan to prevent risks like wandering, unsafe use of appliances, or accidental harm. (Early Stage) Support clients with dementia by helping them start tasks, offering encouragement, and providing frequent cues or reminders as needed. Focus on the client’s enjoyment of the activity rather than task completion, and always follow the care plan. Clients in the early stage of dementia are often aware of their diagnosis and can participate in future care decisions. Symptoms include mild forgetfulness, difficulty finding words, and following conversations. Some clients remain active, while others may withdraw, become anxious, or feel depressed. Caregivers should monitor their emotional well-being and provide support. Abilities Affected Key Symptoms Simplified Support Strategies - Forgetfulness (e.g., recent events) - Use reminders (labels, notes, alarms). - Difficulty learning, concentrating, or - Break tasks into small steps. following directions - Encourage simple conversations. Mental Abilities - Getting lost or poor orientation - Escort clients to appointments when - Trouble finding words or finishing thoughts needed. - Poor judgment or decisions (e.g., driving) - Use safe driving alternatives. - Provide a calm environment. - Blames others for forgetfulness - Encourage sharing feelings. Moods and Emotions - Mood shifts, depression, or irritability - Use stress-relief activities like meditation. - Feels anxious or defensive - Suggest medical support for emotional issues. - Less social, more passive - Promote physical activity. Behaviors - Withdrawn from activities - Encourage meaningful social interaction. - Restless or agitated - Support hobbies or enjoyable activities. - Focus on safe activities. - Remove hazards (e.g., loose cords, scatter Physical Abilities - Mild coordination problems rugs). - Improve lighting for better visibility. In the middle stage of dementia, memory worsens, leading to forgotten personal history and unrecognized family or friends. Clients may pace, become restless, or wander. Registering them with MedicAlert Safely Home ensures they can be located if lost, offering peace of mind to their family. Stage 2: Clients with dementia may respond to loss of abilities by withdrawing from activities or repeating actions or words. Moderate As dementia progresses, clients need more assistance, often beyond what family can provide. Disorientation and difficulties with tasks like dressing or bathing increase, and issues like not tolerating dentures or glasses should be documented in the care plan to ensure safety and (Middle proper care. Long-term care becomes necessary when family and community support are no longer Stage) sufficient, such as when caregivers face health challenges, the client’s behavior poses risks, or the client no longer recognizes their caregiver. Many long-term care facilities have specialized care units (SCUs) for clients with dementia, offering safety, security, and hospice care if needed. Families remain an essential part of the care team, providing comfort, support, and involvement in activities to enhance the client’s well-being. Locked SCUs ensure safety for clients prone to wandering. Abilities Affected Key Symptoms Simplified Support Strategies - Use simple language, speak slowly, and repeat if needed. - Memory loss (forgetting family/friends, personal history) - Offer cues and prompts for tasks. - Disorientation to time, place - Break tasks into steps and use gestures. Mental Abilities - Restlessness (sundowning, pacing) - Limit choices to reduce confusion. - Sleep problems - Ensure safety by monitoring movements and creating a - Trouble following directions, speaking clearly secure environment. - Stay calm and reassure the client. - Mood swings (anxiety, sadness, anger) - Avoid arguing or correcting the client. - Personality changes (suspicion, disorientation) Moods and Emotions - Encourage reminiscing and meaningful activities. - Loss of impulse control (inappropriate language or - Focus on emotions, not just words. behaviors) - Provide a calm and familiar environment. - Identify triggers (hunger, discomfort, noise). - Restlessness, repetitive actions or words - Redirect behavior gently. Behaviors - Delusions, aggression, or uninhibited behaviors - Monitor for physical health issues (pain, infection). - Wandering or pacing - Register with MedicAlert Safely Home for wandering. - Incontinence - Maintain simple and familiar routines. - Difficulty with ADLs (bathing, dressing, eating) - Adapt activities to match abilities. Physical Abilities - Disrupted sleep patterns - Prevent hazards (install grab bars, remove clutter). - Visual-spatial challenges - Consult occupational therapists for additional support. In the final stage of dementia, clients lose the ability to remember, communicate, or perform self-care and require 24-hour assistance. They often Stage 3: Severe become bedridden, struggle with eating and swallowing, and lose control (Late Stages) of bodily functions. This stage typically ends with death, often due to secondary complications like pneumonia. Abilities Affected Key Symptoms Simplified Support Strategies - Use sensory connection: touch, smell, sight, and sound - Loss of memory, communication, and (e.g., hold their hand, play calming music, use familiar independence scents). Mental Abilities - Severe disorientation (time, place, people) - Focus on how you communicate (tone and approach - Dependence for all ADLs matter more than words). - Difficulty processing information - Provide familiar objects, photos, and soothing routines. - Use memory-triggering items (photos, music, or favorite objects). - Withdrawal from conversations Moods and Emotions - Offer comfort through physical presence and familiar - Emotional detachment rituals. - Maintain a calm and supportive environment. - Observe behavior closely to identify needs or - Nonverbal communication (groaning, crying) discomfort. Behaviors - Inability to speak or express needs - Respond gently and use calming strategies like soft - Restlessness or agitation touch or soothing words. - Reposition every 2 hours to prevent sores. - Bedridden and loss of mobility - Use a toileting schedule and monitor bowel health. - Loss of bladder and bowel control Physical Abilities - Offer small, soft meals and keep the client upright - Difficulty eating or swallowing (risk of choking) during and after eating. - Weight loss and physical decline - Provide hydration and skin care regularly.
