What Is Mixed Dementia
It is common for people with dementia to have more than one form of dementia. For example, many people with dementia have both Alzheimer’s disease and vascular dementia.
Researchers who have conducted autopsy studies have looked at the brains of people who had dementia, and have suggested that most people age 80 and older probably have mixed dementia caused by a combination of brain changes related to Alzheimer’s disease,vascular disease-related processes, or another condition that involves the loss of nerve cell function or structure and nerve cell death .
Scientists are investigating how the underlying disease processes in mixed dementia start and influence each other. Further knowledge gains in this area will help researchers better understand these conditions and develop more personalized prevention and treatment strategies.
Other conditions that cause dementia-like symptoms can be halted or even reversed with treatment. For example, normal pressure hydrocephalus, an abnormal buildup of cerebrospinal fluid in the brain, often resolves with treatment.
Researchers have also identified many other conditions that can cause dementia or dementia-like symptoms. These conditions include:
Social And Economic Impact
Dementia has significant social and economic implications in terms of direct medical and social care costs, and the costs of informal care. In 2015, the total global societal cost of dementia was estimated to be US$ 818 billion, equivalent to 1.1% of global gross domestic product . The total cost as a proportion of GDP varied from 0.2% in low- and middle-income countries to 1.4% in high-income countries.

Do You Know The 4 Most Common Types Of Dementia
Have you ever forgotten where you put your keys, why you walked into another room, or what you needed at the grocery store? Theres no question that having memory problems can be a big concern for many people, especially as they get older.
Occasionally misplacing something or momentary forgetfulness does not necessarily mean youre going to get dementia. However, having regular problems with your memory is not normal at any stage in lifeeven for senior citizens.

Dementia Caused By Huntingtons Disease
Huntingtons disease is an inherited degenerative brain disease that affects the mind and body. It usually appears between the ages of 30 and 50, and is characterised by intellectual decline and irregular involuntary movement of the limbs or facial muscles. Other symptoms include personality change, memory disturbance, slurred speech, impaired judgement and psychiatric problems.There is no treatment available to stop the progression of this disease, but medication can control movement disorders and psychiatric symptoms. Dementia occurs in the majority of people with Huntingtons disease.
Understanding The Most Common Types Of Dementia
There are a number of types of dementia. The overlap in symptoms of various dementias can make it hard to get an accurate diagnosis for a particular type. A health care professional will be required to make a proper clinical diagnosis, and this will become the basis for interventions and important treatment decisions. The following information is provided to give you an overview of the different types of dementia as many people are familiar with just the one type, Alzheimers disease.

Memory Loss Or Dementia
In short, dementia, whatever the type, is characterized by various symptoms like memory losses, learning difficulties, language troubles, confusion, mood and personality changes, bad decisions, difficulty in thinking, depression, loss of interest for some activities, etc. Thus, we cant only consider memory disorders to determine if a parent is affected by Alzheimers disease or another type of dementia. In fact, cognitive problems associated with memory may, sometimes, have another origin, like drugs interaction, drinking alcohol, depression, thyroid problems or a lack of vitamins.
If you think one of your parents suffers from Alzheimer of dementia, it is better to visit a doctor, specialized in geriatrics for example. Tell them about the behaviours and troubles that seem to touch the concerned person, in this way the doctor will be able to determine if it actually is dementia, and what type it is. Then they will direct you towards adapted treatments or approaches.

Causes Of Dementia With Lewy Bodies
Lewy bodies are tiny clumps of a protein called alpha-synuclein that can develop inside brain cells.
These clumps damage the way the cells work and communicate with each other, and the brain cells eventually die.
Dementia with Lewy bodies is closely related to Parkinson’s disease and often has some of the same symptoms, including difficulty with movement and a higher risk of falls.

Dementia With Lewy Bodies
The third most common type of dementia is Lewy body dementia , formed when alpha-synuclein proteins that build up along neurons cause cell damage and eventual neural death. This causes dementia symptoms that are similar to Alzheimers disease and vascular dementia, though the hallmark symptom of memory loss often doesnt present itself until later in the stages of Lewy body dementia.
This type of dementia accounts for five to ten percent of dementia diagnoses and primarily affects people between the ages of 50 and 85. Typically, people live for five to eight years after a diagnosis of LBD. Symptoms and treatment of this disease are similar to other dementias, but have some key differences.
The Importance Of Brain Spect Imaging For Memory Problems
All too often, the early signs of dementia might be overlookedeven normalizedso there may not be a red flag until its too late to do much about it. However, like other diseases, the earlier a person is diagnosed with memory problems and follows a comprehensive treatment plan, the better the chances are for a more favorable outcome.
Did you know that dementia processes start developing in the brain decades before the onset of observable symptoms?
This is one of the important reasons the doctors at Amen Clinics use brain SPECT imaging as part of a patients full evaluation. SPECT, which stands for single-photon emission computed tomography, is a functional scan that assesses blood flow patterns. It identifies areas of the brain that have:
- Healthy blood flow
- Low blood flow or too little activity
- High blood flow or too much activity
The various dementing diseases are generally associated with areas of low blood flow. SPECT scans can show the pattern of each type of dementia, which is necessary for providing a correct diagnosis, especially because there are overlapping symptoms, such as memory problems. SPECT can also confirm a suspected diagnosis or identify if a persons cognitive changes are not dementia at all but are caused by a potentially reversible condition such as an infection, toxic exposure, head trauma, or depression.
If you are concerned about memory problemsor have a loved one who isits vital to get assessed and treated as soon as possible.
Who Has Alzheimers Disease
- In 2020, as many as 5.8 million Americans were living with Alzheimers disease.1
- Younger people may get Alzheimers disease, but it is less common.
- The number of people living with the disease doubles every 5 years beyond age 65.
- This number is projected to nearly triple to 14 million people by 2060.1
- Symptoms of the disease can first appear after age 60, and the risk increases with age.
Stimulating Exercises For People With Dementia
Dementia is a progressive disease, meaning symptoms get worse over time. The progression of dementia is different for every individual for some people, it progresses rapidly, whereas for others, it may progress over the span of several years. However, research shows that cognitive stimulation helps reduce decline in cognitive function for individuals with mild to moderate dementia.
Here are 10 stimulating exercises for people with dementia:
1. Create a Memory Box
Since most forms of dementia affect an individuals memory, looking through a memory box with pictures of their loved ones and happy moments can be a great reminiscent activity. The memory box can consist of anything, not just pictures. It promotes engagement opportunities for patients living with dementia, as well as for their loved ones and caregivers.
2.Cook Simple Recipes
The process of cooking and baking requires motor skills, thinking, and short-term memory. Also, the smell or taste of their favourite childhood recipe allows the individual to have a reminiscent experience while cooking. Cooking healthy recipes helps improve general health, and is also beneficial for brain health.
3.Listen and Dance to Music
Similar to the memory box, listening to music that the individual enjoys can provide comfort and feelings of nostalgia. A bonus benefit of this activity is that it encourages dancing, a physical activity that helps keep you in healthy shape!
4 .Work on a Picture Puzzle
5. Household Chores
8. Read a Book

What Are The Most Common Types Of Dementia
- Alzheimers disease.;This is the most common cause of dementia, accounting for 60 to 80 percent of cases. It is caused by specific changes in the brain. The trademark symptom is trouble remembering recent events, such as a conversation that occurred minutes or hours ago, while difficulty remembering more distant memories occurs later in the disease. Other concerns like difficulty with walking or talking or personality changes also come later. Family history is the most important risk factor. Having a first-degree relative with Alzheimers disease increases the risk of developing it by 10 to 30 percent.
- Vascular dementia.;About 10 percent of dementia cases are linked to strokes or other issues with blood flow to the brain. Diabetes, high blood pressure and high cholesterol are also risk factors. Symptoms vary depending on the area and size of the brain impacted. The disease progresses in a step-wise fashion, meaning symptoms will suddenly get worse as the individual gets more strokes or mini-strokes.
- Lewy body dementia. In addition to more typical symptoms like memory loss, people with this form of dementia may have movement or balance problems like stiffness or trembling. Many people also experience changes in alertness including daytime sleepiness, confusion or staring spells. They may also have trouble sleeping at night or may experience visual hallucinations .
The 3 Most Common Types Of Dementia
Before we talk through the different types of dementia, lets first make sure you are aware of what we mean by dementia. Dementia is the umbrella term used to describe a collection of symptoms that are caused by the disorders impacting the brain. Rather, it does not refer to one specific disease, but instead a number of symptoms associated with a number of different neurological conditions.
People with dementia will experience changes with their thinking, ability to perform everyday tasks and behaviour. The extent to which people experience these symptoms will vary from person to person.

Senior Living Options For Seniors With Dementia
The initial stages of dementia are not usually debilitating, and it can be relatively easy to care for yourself at home and bring in a caregiver when you need more help. However, dementia eventually progresses into more serious symptoms like inability to eat and walk, and assisted living may then be a better option to help you enjoy life with Alzheimers disease and other dementias.
Assisted living facilities that specifically provide care for those with dementia are called memory care centers. Memory care facilities provide medical care for people with dementia and other services including:;
- Daily care in areas such as grooming, bathing, dressing, and eating
- Healthy meals, often designed specifically to be dementia-friendly, including fruits and vegetables recommended by top researchers to help fight cognitive decline
- Access to a wide variety of social activities, recreational activities, and specially designed areas to help people suffering from memory loss continue to engage in their lifelong passions like gardening, church, visiting local attractions, art, and more
- Housekeeping services;
- 24-hour monitoring and a secured building to prevent wandering and other dangers
If youre ready to learn more about assisted living options for those living with a diagnosis of dementia, please reach out for information from our senior care experts here.
What Is Known About Alzheimers Disease
Scientists do not yet fully understand what causes Alzheimers disease. There likely is not a single cause but rather several factors that can affect each person differently.
- Age is the best known risk factor for Alzheimers disease.
- Family historyresearchers believe that genetics may play a role in developing Alzheimers disease. However, genes do not equal destiny. A healthy lifestyle may help reduce your risk of developing Alzheimers disease. Two large, long term studies indicate that adequate physical activity, a nutritious diet, limited alcohol consumption, and not smoking may help people. To learn more about the study, you can listen to a short podcast.
- Changes in the brain can begin years before the first symptoms appear.
- Researchers are studying whether education, diet, and environment play a role in developing Alzheimers disease.
- There is growing scientific evidence that healthy behaviors, which have been shown to prevent cancer, diabetes, and heart disease, may also reduce risk for subjective cognitive decline. Heres 8 ways.

How Is Dementia Diagnosed
To diagnose dementia, doctors first assess whether a person has an underlying, potentially treatable, condition that may relate to cognitive difficulties. A physical exam to measure blood pressure and other vital signs, as well as laboratory tests of blood and other fluids to check levels of various chemicals, hormones, and vitamins, can help uncover or rule out possible causes of symptoms.
A review of a persons medical and family history can provide important clues about risk for dementia. Typical questions might include asking about whether dementia runs in the family, how and when symptoms began, changes in behavior and personality, and if the person is taking certain medications that might cause or worsen symptoms.
The following procedures also may be used to diagnose dementia:
Early detection of symptoms is important, as some causes can be treated. However, in many cases, the cause of dementia is unknown and cannot be treated. Still, obtaining an early diagnosis can help with managing the condition and planning ahead.
Isnt Dementia Part Of Normal Aging
No, many older adults live their entire lives without developing dementia. Normal aging may include weakening muscles and bones, stiffening of arteries and vessels, and some age-related memory changes that may show as:
- Occasionally misplacing car keys
- Struggling to find a word but remembering it later
- Forgetting the name of an acquaintance
- Forgetting the most recent events
Normally, knowledge and experiences built over years, old memories, and language would stay intact.
