Today, we're talking about clinical trials for disorders that can cause Dementia, and interventions that might seek to avoid cognitive decline or enhance overall brain health. What is a Clinical Trial? A typical clinical trial is a research study that helps researchers learn more about how to treat or manage a disease or syndrome. Individuals who join clinical trials may try new medicines, non-medical therapies, or care methods that are not yet widely available. There are clinical trials for Alzheimer's disease, vascular Dementia, Lewy body Dementia, frontotemporal Dementia, and other Dementia-related conditions. Some trials test new drugs to slow memory loss or protect brain cells. Others study changes in diet, exercise, or sleep to see if they help people think more clearly or feel better. Before joining a clinical trial, the person living with Dementia and their family will learn what the study involves. This should include discussing the risks, the possible benefits, and what the time commitment is. All trials are voluntary, and participants can usually stop at any time. Medical and research teams closely watch clinical trials to keep people safe. Moreover, some trials may pay for travel or offer small payments for taking part. One of the most significant benefits of joining a trial is that it can help you or others in the future by contributing to the search for better treatments or even cures. If you or a loved one is interested, talk to your medical team or visit trusted websites like clinical trials.gov to learn more.

It is a prescription medicine often used to treat people with Alzheimer's disease, one cause of Dementia that affects memory thinking and behavior. It is also used off-label with specific other causes of Dementia. Donepezil does not cure the disease. Yet it may provide a slight improvement in symptoms for a while. It works by helping certain brain chemicals that support memory and thinking. Some people who take it may feel more alert or able to do daily tasks a little more easily. Taken orally, donepezil is typically taken once daily with or without food, and it's essential to take it at the same time each day. A slightly different formula is available as a multi-day patch on the skin. Like all medicines, donepezil can have side effects. Some people may feel sick to their stomach, have trouble sleeping, have nightmares, or feel dizzy. These side effects are usually mild, but if they worsen, it's essential to inform the doctor. Donepezil works best when taken as part of a complete care plan, including support from caregivers and healthy daily routines. Monitor its usefulness in collaboration with the medical team and discuss when or if the dose should be adjusted or discontinued.

Today we are going to talk about finger foods and how they can help people living with Dementia. Eating can sometimes become difficult as Dementia progresses. Using utensils like forks, knives, or even spoons can feel confusing or frustrating. This may cause someone to eat less, lose weight, or feel embarrassed at meal times. That is where finger foods can make a big difference. What are finger foods? Finger foods are small, easy-to-hold foods that can be picked up and eaten without needing silverware. Examples include slices of fruit, cheese cubes, small sandwiches, vegetable sticks, or bite sized pieces of chicken or fish. These foods are simple to handle, reduce spills, and can help a person feel more independent. Why use finger foods? First, they allow someone with Dementia to eat with more comfort and confidence. The act of picking up food feels natural and familiar. Second, finger foods encourage better nutrition because they are easy to eat. People are more likely to finish a meal or snack throughout the day. Third, finger foods give back a sense of dignity. Eating without struggling helps the person feel capable and respected. Finally, finger foods can support social connections. Sharing a plate of small foods makes mealtimes feel warm and inviting. How to use finger foods effectively? Offer a variety of healthy options in small amounts. Use foods that are soft and easy to chew. Keep choices colorful and appealing to make eating enjoyable. Most importantly, be patient and supportive. Remembering that meals are not just about food, but also about comfort, pleasure and connection.

Today, we're talking about hospice care, a special kind of care for people who are near the end of life. Hospice focuses on comfort, not cure. It is meant for people who have a serious illness and are expected to live about six months or less, based on a doctor's judgment. Surprisingly, hospice may be paused depending on improvements to the person's rate of decline. On the other hand, if appropriate, it may also be renewed by the medical team after the first six months. The main goal of hospice is to help the person feel peaceful, comfortable, and supported. Hospice care helps with pain, breathing trouble, anxiety, and other distressing symptoms. It also provides support for family members and caregivers. Hospice care can be given in the person's home, a nursing home, an assisted living facility, or a dedicated hospice center. A team of people usually helps, including doctors, nurses, social workers, home health aides, chaplains, and volunteers. They all work together to meet the person's physical, emotional, and spiritual needs. Choosing hospice does not mean giving up. It means focusing on comfort and quality of life, rather than pursuing treatments that may no longer be effective. You can also stop hospice at any time if the situation changes. Hospice can help people with many illnesses, including advanced Dementia, cancer, heart failure, and others. It is often paid for by Medicare, Medicaid, or private insurance. Simply talking about hospice early, openly, and often can help families make better decisions and prepare in a calm, loving way. Having a conversation about hospice preferences in midlife instead of just at the end of life is becoming more common.

Today, we're talking about oral hygiene, or how to take care of the mouth, teeth, and gums, especially for people living with Dementia. Good oral care helps prevent tooth pain, gum disease, infections, and bad breath, and it can make eating and speaking easier. Tips for Maintaining Oral Hygiene in Dementia As Dementia progresses, it can be harder for a person to remember or manage brushing and flossing. That's where caregivers can help. Using gentle support and simple steps, try using cueing, which means giving short, clear instructions or showing the task step by step. For example, hand them the toothbrush and say, "Let's brush your teeth now," while brushing your teeth to model the behavior. Use the same time and place each day to build a routine. You can even find videos online and play them to show someone brushing their teeth. Use a soft-bristle toothbrush and fluoride toothpaste, and brush for about two minutes. Don't forget to clean the tongue gently using the toothbrush or a tongue scraper to reduce bacteria and bad breath. If the person wears dentures or has implants or bridges, be sure to clean them daily. Remove dentures at night and soak them in a denture cleaner. Check the mouth often for sores, redness, or loose teeth or devices. Flossing can be tricky for someone living with Dementia. Using waxed string floss or dental tape may expose fingers to injury. Consider a water flosser if you believe that regular floss may be dangerous, but start on the lowest pressure. Fill the reservoir with body temperature water, and use a calming voice and movement, as the jet spray might scare someone and cause them to bite down on the flossing wand. Keep dental visits up to date. Some dentists are familiar with issues arising from cognitive impairments. Still, others may need a pre-appointment visit to build awareness with the staff regarding how the person may react. Sitting with the person and holding their hand can be comforting if the person is resistant. Try brushing at a more relaxed time or use music and gentle reassurances to calm them. Even wiping the teeth with a warm, damp cloth is better than nothing. On behalf of the Dementia Society of America ® , thank you again for joining me today.

This is a type of Dementia caused by reduced blood flow to the brain. The brain requires oxygen and nutrients to function correctly. When blood cannot reach certain areas of the brain, those parts can become damaged, likely resulting in significant cognitive challenges. Vascular Dementia often happens after a stroke or after many small strokes over time. These small strokes are sometimes called mini strokes, or TIAs, which stands for T ransient I schemic A ttacks. A TIA is a brief blockage of blood flow in the brain. It doesn't usually cause lasting damage, but it's a warning sign that a bigger stroke could happen. Another term you might hear is multi-infarct Dementia. This means a person has had many small strokes that slowly cause damage in different parts of the brain. Over time, these seemingly insignificant and almost unnoticeable blood vessel injuries accumulate and can have a lasting impact on brain function. Common signs and symptoms of vascular Dementia may include poor attention, confusion, trouble walking, mood changes, problems making decisions, and urinary incontinence. Unlike Alzheimer's disease, memory loss may not be the first sign, but it often shows up later. There is no cure, but treatment may slow the progression and might alleviate symptoms. Medical professionals may recommend managing high blood pressure, cholesterol, diabetes, and other cardiovascular conditions. Quitting smoking, eating a healthier diet, getting more active, and taking medications as directed are likely to be strongly advised. If you notice changes in thinking or movement in yourself or a loved one, talk to a medical professional. Getting help early means better planning and better care.

Today, we're talking about whether the diseases and disorders that underlie the syndrome of Dementia are genetic. The short answer is that for most people, Dementia is caused by a mix of different factors, and only some types of Dementia have a strong genetic link. In a relatively small percentage of cases, certain kinds of Dementia, mostly forms that appear at a younger age, are more directly caused by changes or mutations in specific genes. If someone has one of these rare gene changes, they are very likely to develop a disease, often before age 65. These cases usually run strongly in families, but they are uncommon. For most people, genetics plays a minor role. Having a parent or sibling with Dementia may slightly increase your risk, but it does not mean you will develop it. Other factors, such as age, overall health, lifestyle, and environment, are often more important in determining risk. In addition, some genes can increase the chance of developing Dementia later in life. However, many people with these genes never get Dementia, and many people without them do. The good news is that healthy lifestyle choices such as staying active, eating well, managing blood pressure, stopping and avoiding smoking, and keeping your mind engaged can help lower the risk, even if you have a family history. If you are worried about your genetic risk, talk with your doctor. They may recommend genetic testing and counseling to help you understand your particular situation.

When someone with Dementia needs assistance, emergencies can be stressful and confusing, but with a bit of planning, you can help the person receive better, safer care. Start by gathering important information. Keep a folder near the front door, or consider having a specially marked container in the refrigerator with the person's full name, birth date, medical conditions, medications, allergies, and emergency contacts. Include copies of any legal documents, like a do-not-resuscitate (DNR) order, power of attorney (POA), or health care proxy. Some families also keep this information in a wallet, purse, or on their phone. It's also smart to write a short note explaining the person's Dementia diagnosis, how it affects them, how they communicate, what calms them, and any behaviors emergency medical technicians, also known as EMTs, might expect. This helps first responders be more gentle and prepared. One crucial step you can take is to register the person with your local 911 center. Many communities offer a special needs registry where you can share medical and behavioral information in advance. Then, when you call 911, dispatchers should already know there is a person living with Dementia at the address. Contact your local non-emergency police or fire department to inquire about the availability of this service in your area. When the Ambulance Arrives When EMTs arrive, stay calm and clear. Let them know the person has Dementia. Explain what is normal for them, and share your information packet. Let them know why you called for emergency assistance and how their behavior is different than usual. If the person is upset or afraid, suggest ways to comfort them, such as using a reassuring tone of voice, playing their favorite calming music from an app on your smartphone, and holding their hand. It's almost always better to have a trusted person ride along. Second best is to meet them at the hospital to help explain things and reduce confusion. Good communication and planning can help ensure a safe and respectful experience for everyone involved. On behalf of the Dementia Society of America ® , thank you again for joining me today.

Dementia is a syndrome, a collection of symptoms, typically expressed as changes in memory, thinking, and ability to perform activities of daily living. Many people believe that Dementia is just a normal part of aging, but that's not necessarily true. What are some risk factors for developing Dementia? While getting older is the biggest risk factor, not everyone will develop Dementia. Other factors, including health, lifestyle, and family history, can also increase the chances of developing this condition. One major risk factor is family history and genetics. However, having a parent or close blood relative with Dementia does not mean someone will definitely develop Dementia. It just increases the risk. Certain health conditions can also play a role. Diabetes, high cholesterol, COPD, high blood pressure and heart disease can affect the brain leading to damage over time. Head injuries like concussions may also increase the risk, especially if someone has had multiple injuries. Lifestyle choices are important for brain health. Smoking, drinking, excess alcohol, eating unhealthy foods and not exercising can all increase the risk of Dementia. Staying active, eating a balanced diet and avoiding harmful substances can help protect the brain. Social and mental activity are also key factors. People who stay engaged in conversations, spend time with family and friends and do activities like reading or solving complex problems or puzzles may lower their risk. Loneliness, depression, and long-term stress can have negative effects on brain function. Keeping the mind active and maintaining social connections can help reduce the chances of cognitive decline. Another important factor is sleep quality. Poor sleep, especially conditions like sleep apnea, can impact memory and thinking abilities. Getting enough rest each night allows the brain to repair itself and function properly. Although some risk factors like age and genetics cannot be changed, now you know that there are ways to lower the risk of Dementia. Even small changes like walking more often or spending time with loved ones can make a difference. Taking steps to improve overall health and well-being may not guarantee Dementia prevention, but they can help reduce the chances of developing it and promote a better quality of life.

As you might guess, this is a complex issue with no simple answers, but I'll do my best to give you the big picture overview. Where are some places to look for help paying for Dementia care? First, there is Medicare, a government health insurance program for people age 65 and older. Medicare may cover doctor visits, hospital stays, medicines, and short-term rehab care, but it does not pay for long-term care, like help at home or in a safe and secure care community, often referred to as memory care. Medicaid is another government program for people with low income and limited savings. Medicaid may help pay for long-term care, including nursing homes, and in some cases, care at home. Each state has its own rules, so it's important to check with your local Medicaid office. Some people use private health insurance or long-term care insurance if they have it. These plans may help with services that Medicare does not cover. Others may need to use personal savings, retirement income, or help from family to pay for care. In some cases, veterans benefits can help if the person with Dementia served in the military. Some states or local programs also offer financial help for caregivers: home care, support, respite or adult day programs. Payment for family caregiving depends on several factors, including state regulations, which vary across the country and set different rules, eligibility requirements, and payment rates. In addition, often the person receiving care must meet specific criteria for a program or insurance to cover the costs. The level of care needed, such as the amount of assistance required and the complexity of tasks is a key factor. In some cases, the caregiver's experience or training may be considered with certain programs requiring specific qualifications or certifications. Who can help with figuring out the best strategy for Dementia care? It's a good idea to talk with a professional geriatric care manager, elder care attorney, or financial planner who understands Dementia care. They can help you look at your options and plan ahead. Paying for Dementia care can be challenging, but knowing what help is available can make a big difference. On behalf of the Dementia Society of America ® , thank you again for joining me today.

Polls and surveys help the Dementia Society serve those most in need. Findings: Dementia Society of America Reveals 82% of Americans Agree People Living with Dementia Can Live Meaningful Lives with Proper Care DOYLESTOWN, PA, UNITED STATES , March 12, 2026 / EINPresswire.com/  — A new national poll by Dementia Society of America ®  finds that 82% of Americans with experience related to Dementia believe people living with the syndrome can still live meaningful lives with the right care and support. The poll surveyed 1,465 individuals and revealed a strong public consensus on the importance of education, supportive care, and non-medical engagement for those living with Dementia. Notably, 98% of respondents agreed or strongly agreed that Dementia education is essential for providing effective support. Kevin Jameson, Founder and CEO of Dementia Society of America, speaks to the mandate for increased resources “The data shows a strong public mandate for increased resources and training for those navigating the complexities of Dementia,” said Kevin Jameson, Founder and CEO of Dementia Society of America. “While Dementia remains one of our greatest healthcare challenges, these results point to a growing sense of hope. With 82% believing a meaningful life is possible with the right support, the mission of Dementia Society and other organizations is clearer than ever. We remain committed to bridging the gap between medical care and the human connection found through music, art, and specialized education.” Kevin Jameson continued, “We are deeply grateful to our donors and partners, whose support enables us to serve individuals and families in need.” Key findings of the Dementia Society poll include : A majority of respondents, 82%, strongly agree or agree that a person living with Dementia can live a meaningful life with the right support. The vast majority of respondents, nearly 98%, identify Dementia as one of the most significant healthcare challenges of our time. Non-medical therapies, including music and art, are viewed by 87% of people as playing an important role in supporting those living with Dementia.

In this post, we'll explore the two main types of clinical research and how each type contributes to advancements in Dementia care. What is Clinical Research? Clinical research is the process scientists use to learn more about health, illness, and how to treat or prevent disease. This type of research involves real people — not just animals or cells in a lab. It helps doctors and scientists figure out what works, what doesn’t, and why. According to the NIH, clinical research can fall into two big categories: clinical trials  and observational studies . We'll talk about each type of study and how it contributes to advances in Dementia treatment. What Is a Clinical Trial (Interventional Study)? A clinical trial is a type of research study where scientists give participants a specific treatment or intervention  to see what effect it has. Because someone must receive something new or different, these studies are also called interventional trials. In a clinical trial: Researchers decide what treatment or therapy people will receive. Some participants might get a new drug, device, therapy, or approach. Others might get a standard treatment or a placebo (a “fake” treatment used for comparison). Scientists then measure differences between groups to learn if the new thing helped, didn’t help, or caused side effects. This kind of research is how doctors find out if a new treatment actually works . Example of an Interventional Trial— A Dementia Drug Trial One well-known example from Dementia research is the lecanemab trial . This clinical trial tested whether a new drug could slow the progression of early Alzheimer’s disease. In the study, people with mild memory loss or early Dementia were randomly assigned to receive either lecanemab or a placebo. Scientists then checked whether the drug group showed slower cognitive decline than the placebo group. This is the kind of trial that helps the FDA (the U.S. Food and Drug Administration) decide whether a treatment should be approved for wider use. What Is an Observational Study? An observational study is also a form of clinical research, but scientists do not assign treatments or change anything in participants' lives. Instead, they watch and measure what already happens naturally . In an observational study: People continue with their regular medical care. Researchers collect data — like health measurements, behaviors, and outcomes. The goal is to see patterns  and relationships  that could help us understand risk factors, disease progression, or caregiving effects. Because observational studies do not change treatment, they don’t prove cause and effect the way interventional trials do. Instead, they help scientists find clues  about what might be linked to disease or health. Example — Dementia Observation Research A famous example is the Religious Orders Study , which follows older adults, such as nuns and priests, over many years. Participants have regular health and memory checks, and sometimes agree to donate their brains after death for scientific study. This long-term data helps researchers understand how aging affects the brain and why some people develop Dementia while others don’t. Another long-term observational study is the Nun Study , which examined how lifestyle, education, and early-life experiences might relate to Dementia risk. These kinds of studies don’t test a new drug or treatment. Instead, they help researchers spot patterns and potential risk factors that could inform future clinical trials. So What’s the Real Difference? At a basic level: Clinical trials (interventional studies)  test whether something new works — like a treatment or therapy. Observational studies   watch what happens naturally  without assigning treatments. Both are important, but they serve different purposes: Study Type What Happens? What It Answers Clinical Trial (Interventional) Participants receive a specific treatment or intervention chosen by researchers Does the new treatment work? Does it cause benefits or harm? Observational Study Participants are watched over time without changing care What patterns exist? What factors might  relate to disease or outcomes? For example, observational studies might identify that exercise and a healthy diet are linked to lower Dementia risk. But only clinical trials can test  whether a structured exercise program actually prevents Dementia. Why Both Types Matter in Dementia and Dementia Care Observational studies can help scientists understand how Dementia develops, how caregivers are affected, and what lifestyle factors influence health. They often involve surveys, brain tests, medical records, or long-term follow-ups. Clinical trials can provide evidence about interventions — like new medicines, caregiving training, or therapy programs — to see if they improve outcomes  for people with Dementia or their caregivers. Together, these approaches give a fuller picture: what might help people stay healthy, how disease actually progresses, and whether new approaches truly make a difference. Want to Learn More?
