Alzheimer Hallucinations

Peter Brissette • April 11, 2016

Understanding the difference between Alzheimer hallucinations and delusions is important. A delusion is defined as a false idea, sometimes originating in a misinterpretation of a situation. For example, when individuals with dementia have a delusion, they think that family members are stealing from them or that the police are following them.

A hallucination, in contrast, is a false perception of objects or events, and is sensory in nature. When individuals with Alzheimer’s have a hallucination, they see, hear, smell, taste or even feel something that isn’t really there. Hallucinations are caused by changes within the brain that result from the disease.

Alzheimer Hallucinations are visual and auditory. Individuals may see the face of a former friend in a curtain or may see insects crawling on their hand. In other cases, they may hear people talking to them and may even talk to the imagined person.

Hallucinations can be frightening. On some occasions, individuals may see threatening images or just ordinary pictures of people, situations or objects from the past. Some ideas for handling hallucinations are outlined in this fact sheet.

See the doctor

Ask the doctor to evaluate the person to determine if medication is needed or might be causing the hallucinations. In some cases, hallucinations are caused by schizophrenia, a disease different from Alzheimer’s.

Have the person’s eyesight or hearing checked. Also make sure the person wears his or her glasses or hearing aid on a regular basis.

The physician can look for physical problems, such as kidney or bladder infections, dehydration, intense pain, or alcohol or drug abuse. These are conditions that might cause hallucinations. If the physician prescribes a medication, watch for such symptoms as over sedation, increased confusion, tremors or tics.

Assess and evaluate

Assess the situation and determine whether or not the hallucination is a problem for you or for the individual. Is the hallucination upsetting to the person? Is it leading him or her to do something dangerous? Does the sight of an unfamiliar face cause him or her to become frightened? If so, react calmly and quickly with reassuring words and comforting touching.

Respond with caution

Be cautious and conservative in responding to the person’s hallucinations. If the hallucination doesn’t cause problems for you, the person or other family members, ignore it.

Don’t argue with the person about what he or she sees or hears. Unless the behavior becomes dangerous, you might not need to intervene.

Alzheimer Hallucinations Offer reassurance

Reassure the person with kind words and a gentle touch. For example, you might want to say: Don’t worry. I’m here. I’ll protect you. I’ll take care of you, or I know you’re worried. Would you like me to hold your hand and walk with you for awhile? Gentle patting may turn the person’s attention toward you and reduce the hallucination.

Also look for reasons or feelings behind the hallucination and try to find out what the hallucination means to the individual. For example, you might want to respond with words such as these: It sounds as if you’re worried or I know this is frightening for you.

Use distraction

Suggest that the person come with you on a walk or sit next to you in another room. Frightening hallucinations often subside in well-lit areas where other people are present.

You might also try to turn the person’s attention to a favorite activity, such as listening to music, drawing, looking at a photo album or counting coins.

Respond honestly

Keep in mind that the person may sometimes ask you about the hallucination. For example, do you see him? You may want to answer with words such as these: I know that you see something, but I don’t see it.” In this way, you’re not denying what the person sees or hears or getting involved in an argument.

Assess the reality of the situation

Ask the person to point to the area where he or she sees or hears something. Glare from a window may look like snow to the person, and dark squares on tiled floor may look like dangerous holes.

Modify the environment

If the person looks at the kitchen curtains and sees a face, you may be able to remove, change or close the curtains. Check the surroundings for noises that might be misinterpreted, for lighting that casts shadows, or for glare, reflections or distortions from the surfaces of floors, walls and furniture.

If the person insists that he or she sees a strange person in the mirror, cover up the mirror or take it down. It’s also possible that the person doesn’t recognize his or her own reflection.

Turn on more lights to reduce shadows that could look scary to your loved one. Hallucinations are very real to the person you care for. You can ease feelings of fear by using words that are calm, gentle and reassuring.

Gardening for Seniors: Benefits and Accessible Gardening Ideas in Assisted Living

October 17, 2025
Gardening offers numerous benefits for seniors, particularly those residing in assisted living communities. Engaging in gardening activities provides physical exercise, mental stimulation, and opportunities for social interaction. The fresh air and connection to nature further enhance overall well-being. Incorporating accessible gardening ideas ensures that all seniors, regardless of mobility levels, can participate and reap these benefits. Assisted living communities that integrate gardening into their programs create enriching environments for residents. By tailoring gardening activities to meet the needs of seniors, these communities promote active lifestyles and improve quality of life. 1. Physical Benefits of Gardening for Seniors Gardening is a low-impact physical activity that enhances strength, flexibility, and endurance. Tasks such as planting, weeding, and watering involve various muscle groups, promoting overall fitness. Regular physical activity through gardening can help manage weight, reduce the risk of chronic diseases, and improve cardiovascular health. According to a study , gardening has strong physical health benefits for older adults. Engaging in gardening also improves hand-eye coordination and fine motor skills. Handling tools and plants requires precision, which can enhance dexterity. Maintaining motor skills is crucial for daily activities and contributes to sustained independence. Moreover, the physical exertion involved in gardening can lead to better sleep patterns, further benefiting overall health. Exposure to sunlight during gardening increases vitamin D levels, which are essential for bone health. Adequate vitamin D helps prevent osteoporosis and fractures, which are common concerns among seniors. However, to reduce the risk of skin cancer, it's important to balance sun exposure with skin protection. Wearing appropriate clothing and sunscreen can mitigate these risks. The right gardening ideas also encourage functional movement, such as bending and stretching, which enhance flexibility. These movements can alleviate stiffness and improve joint health. Maintaining flexibility is vital for comfortably performing daily tasks. Furthermore, the weight-bearing aspects of gardening activities help strengthen bones and muscles. Gardening can also be a form of aerobic exercise. Activities like raking and digging elevate heart rates, promoting cardiovascular fitness. This aerobic component contributes to overall stamina and energy levels. Incorporating regular gardening sessions into routines can lead to long-term health benefits. 2. Mental and Emotional Benefits Gardening has been linked to improved mental health, reducing symptoms of depression and anxiety. Nurturing plants provides a sense of purpose and accomplishment. Engaging with nature has a calming effect, lowering stress levels and promoting relaxation. According to experts , gardening has been scientifically proven to improve both mental and physical health, contributing to a longer and happier life.  Gardening activities stimulate the brain through sensory experiences such as touching soil and smelling flowers. These stimuli can evoke positive memories and emotions, which is particularly beneficial for seniors with dementia. Gardening activities also encourage mindfulness, keeping individuals present and engaged. This focus can distract from negative thoughts and improve mood.

Exploring the Benefits of Adult Day Care Programs

September 30, 2025
Adult daycare programs have emerged as vital components in the continuum of care for older adults. These programs offer structured, daytime support, allowing seniors to engage in social, therapeutic, and health-related activities while returning to their homes in the evening. Adult daycare provides a flexible and supportive solution for families balancing caregiving responsibilities with other commitments. Understanding the multifaceted benefits of these programs is essential for making informed care decisions.​ The demand for adult day care services is growing, reflecting the needs of an aging population seeking alternatives to full-time residential care. According to the CDC , over 5,100 adult day services centers in the United States serve approximately 182,000 participants daily. These centers cater to individuals with varying levels of physical and cognitive abilities and provide personalized care plans. Exploring the specific advantages of adult day care can illuminate its role in promoting senior well-being and family support.​ How Adult Day Care Programs Improve Social Engagement Social isolation is a significant concern among older adults, often leading to adverse health outcomes. Adult day care programs address this issue by fostering a community environment where seniors can interact with peers. Engaging in group activities , such as art classes, music sessions, and games, encourages socialization and reduces feelings of loneliness. Regular participation in these programs can lead to improved mood and cognitive function.​ The structured nature of adult day care ensures that participants have access to consistent social opportunities. Centers often organize events and outings, providing variety and stimulation. These activities are designed to be inclusive, accommodating different interests and abilities. Such engagement is crucial for maintaining a sense of purpose and belonging among seniors.​ 

Meaningful Ways to Spend Quality Time with Loved Ones in Assisted Living

September 25, 2025
Maintaining strong connections with loved ones in assisted living is vital for their emotional and psychological well-being. Regular, meaningful interactions can significantly enhance a resident's quality of life, providing comfort and a sense of belonging. Understanding the best ways to spend quality time together fosters these benefits.​ Assisted living communities offer various opportunities for families to connect with residents through structured and informal activities. These environments are designed to support social engagement, making it easier for loved ones to participate in residents' daily lives. From communal events to personalized visits, numerous ways exist to create meaningful experiences. Exploring these options can help families make the most of their time together.​  Engage in Shared Activities in Assisted Living Participating in activities together can be a fulfilling way to spend time with loved ones in assisted living. Simple actions like reading a book aloud, working on a puzzle, or watching a favorite movie can provide comfort and enjoyment. These shared experiences can evoke positive memories and foster a sense of normalcy. Such activities can also stimulate emotion, conversation, and connection.​ Creative pursuits like painting, knitting, or crafting can be therapeutic and enjoyable. These activities allow residents to express themselves and can be a source of pride and accomplishment. Family members participating in these creative endeavors can strengthen their bond with the resident. Additionally, displaying completed projects can boost the resident's self-esteem and provide conversation starters.​

Healthy Holiday Eating: Tips for Seniors to Enjoy Festive Meals Without Sacrificing Their Health

September 23, 2025
The holiday season brings joy, togetherness, and an abundance of delicious meals. For a senior, it's a time to celebrate with loved ones while being mindful of their health. Maintaining a balanced diet during festive gatherings is essential to ensure overall well-being. Assisted living communities are crucial in supporting seniors who enjoy holiday feasts without compromising their health.​ Assisted living facilities recognize the importance of nutrition in senior health. They provide tailored meal plans catering to individual dietary needs, ensuring seniors receive the necessary nutrients. These communities also offer educational programs to promote healthy eating habits among residents. Focusing on nutritional awareness helps seniors make informed choices during the holiday season.​ Understanding Nutritional Needs During the Holidays As people age, their nutritional requirements change , necessitating diet adjustments. Seniors often need fewer calories but more of certain nutrients like calcium, vitamin D, and fiber. During the holidays, indulging in calorie-dense foods that lack essential nutrients is easy. Assisted living communities address this by offering festive and nutritionally balanced meals.​ Protein intake is vital for senior health, helping maintain muscle mass and strength. Holiday meals can be tailored to include lean proteins such as turkey or plant-based alternatives. Incorporating these options helps seniors meet their protein needs without excessive saturated fats. Assisted living facilities ensure that holiday menus are designed with these considerations.​ Fiber is another crucial component of a senior's diet, aiding in digestion and preventing constipation. Holiday dishes can be modified to include whole grains, fruits, and fiber-rich vegetables. Seniors can enjoy traditional meals while supporting their digestive health. Assisted living communities prioritize these dietary adjustments during festive seasons.​ Hydration is often overlooked but is essential for seniors, especially during the holidays when alcohol and caffeinated beverages are prevalent. Encouraging water intake and offering hydrating foods like soups and fruits can help maintain proper hydration levels. Assisted living facilities monitor residents' fluid intake to prevent dehydration. Managing Chronic Senior Health Conditions with Holiday Foods Many seniors manage chronic conditions such as diabetes, hypertension, or kidney disease, which require specific dietary considerations. Holiday meals can be adapted to accommodate these needs without sacrificing flavor. Assisted living communities work closely with dietitians to create menus that align with senior residents’ health requirements. Controlling carbohydrate intake is crucial to managing blood sugar levels for seniors with diabetes. To reduce glycemic impact, holiday dishes can be prepared with whole grains and natural sweeteners. Assisted living facilities provide alternatives that allow diabetic residents to enjoy desserts in moderation. Thoughtful substitutions make holiday meals inclusive for all.​

Navigating the Holidays with Grief: Supporting Seniors Who Have Experienced Loss

September 18, 2025
The holiday season often evokes feelings of joy, togetherness, and celebration. However, for seniors who have experienced the loss of a loved one, this time can be particularly challenging. Memories of past holidays may intensify grief and loneliness, making it difficult to engage in festivities. Recognizing and addressing these emotions is crucial for the well-being of grieving seniors.​ Emotional support during the holidays is essential for seniors coping with loss. Providing a compassionate environment where they can express their feelings helps heal. Understanding the unique challenges grieving seniors face allows caregivers and family members to offer appropriate support. Understanding Holiday Grief in Seniors  Holiday grief in seniors is a multifaceted experience influenced by personal loss, societal expectations, and seasonal changes. The contrast between festive surroundings and internal sorrow can exacerbate feelings of isolation. Seniors may struggle with participating in traditions that once brought joy but now serve as reminders of their loss. Acknowledging these complexities is the first step in providing adequate support.​ Research indicates that nearly 95% of individuals who have experienced loss report at least one symptom of physical or mental distress during the holidays. These symptoms can include depression, anxiety, and sleep disturbances, which may be more pronounced in older adults. Understanding the prevalence of these issues underscores the importance of proactive emotional support. Caregivers should be vigilant in recognizing signs of holiday grief so they can intervene appropriately.​

Helping Seniors Document Their Life Stories and Share Their Wisdom

September 17, 2025
Seniors hold a wealth of life experience that must be documented and shared. Their stories reflect unique perspectives on history, family, resilience, and personal growth. Telling senior life stories helps them connect to others and reaffirm their identity. Life review is an essential part of emotional well-being in assisted living communities. Senior life stories provide a powerful sense of purpose. Creating space for storytelling allows residents to reflect on meaningful moments that shaped who they are. It also strengthens their relationships with family members and caregivers. In assisted living environments, this process can be transformative for both the storyteller and the listener. Creating a Supportive Space for Storytelling A calm, comfortable environment is essential for encouraging residents to open up. Seniors often feel more secure sharing memories in familiar and nonjudgmental spaces. Thoughtful design, familiar objects, and caring staff help create the right setting. Quiet areas with soft lighting and personal touches can foster better memory recall . Caregivers and staff should ask open-ended questions that guide seniors into their memories. Instead of yes-or-no inquiries, questions like “What was your first job?” or “What holidays meant the most to your family?” open doors to rich conversation. Allowing time for thoughtful responses reduces pressure and increases comfort. Gentle prompting paired with genuine curiosity builds trust.
