What Is Mixed Dementia

Symptoms of 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.

In addition, medical conditions such as stress, anxiety, depression, and delirium can cause serious memory problems that resemble dementia, as can side effects of certain medicines.

Researchers have also identified many other conditions that can cause dementia or dementia-like symptoms. These conditions include:

What Is The Treatment For Dementia

Treatment options for Alzheimer’s disease and other dementia are limited. While there are medications available to try to improve the symptoms of Alzheimer’s disease, the effect of these medications is limited. Physical exercise has been shown to be of some benefit in helping to maintain cognition. Staying engaged and participating in social events may also be of some help. To date, no treatment which can reverse the process of Alzheimer’s disease has been identified.

Difficulty Finding The Right Words

Another early symptom of dementia is struggling to communicate thoughts. A person with dementia may have difficulty explaining something or finding the right words to express themselves. Having a conversation with a person who has dementia can be difficult, and it may take longer than usual to conclude.

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.

Who Can Diagnose Dementia

Dementia 101: Symptoms, Types, Stages &  Prevention

Visiting a primary care doctor is often the first step for people who are experiencing changes in thinking, movement, or behavior. However, neurologists doctors who specialize in disorders of the brain and nervous system are often consulted to diagnose dementia. Geriatric psychiatrists, neuropsychologists, and geriatricians may also be able to diagnose dementia. Your doctor can help you find a specialist.

If a specialist cannot be found in your community, contact the nearest medical school neurology department for a referral. A medical school hospital also may have a dementia clinic that provides expert evaluation. You can also visit the Alzheimers Disease Research Centers directory to see if there is an NIA-funded center near you. These centers can help with obtaining a diagnosis and medical management of conditions.

Movement Problems And Lewy Body Dementia

Some people with LBD may not experience significant movement problems for several years. Others may have them early on. At first, movement symptoms, such as a change in handwriting, may be very mild and easily overlooked. Movement problems may include:

  • Muscle rigidity or stiffness

Can Dementia Be Prevented

Although dementia cannot be prevented, living a health-focused life might influence risk factors for certain types of dementia. Keeping blood vessels clear of cholesterol buildup, maintaining normal blood pressure, controlling blood sugar, staying at a healthy weight basically, staying as healthy as one can can keep the brain fueled with the oxygen and nutrients it needs to function at its highest possible level. Specific healthful steps you can take include:

  • Follow a Mediterranean diet, which is one filled with whole grains, vegetables, fruits, fish and shellfish, nuts, beans, olive oil and only limited amounts of red meats.
  • Exercise. Get at least 30 minutes of exercise most days of the week.
  • Keep your brain engaged. Solve puzzles, play word games, and try other mentally stimulating activities. These activities may delay the start of dementia.
  • Stay socially active. Interact with people discuss current events keep your mind, heart, and soul engaged.

What Are The Risk Factors For Dementia

Dementia Signs, Symptoms, Causes, Tests, Treatment, Care

The risk factors for developing dementia include age and family history. Age and a family history of dementia are non-modifiable risk factors. Abnormal genes which are associated with Alzheimer’s disease have been identified, but are only rarely involved in the development of Alzheimer’s disease. Conditions such as high blood pressure, high cholesterol, or diabetes increase the risks of developing either Alzheimer’s disease or multi-infarct dementia. Some medications can lead to memory problems which look like dementia.

What Increases The Risk For Dementia

  • AgeThe strongest known risk factor for dementia is increasing age, with most cases affecting those of 65 years and older
  • Family historyThose who have parents or siblings with dementia are more likely to develop dementia themselves.
  • Race/ethnicityOlder African Americans are twice more likely to have dementia than whites. Hispanics 1.5 times more likely to have dementia than whites.
  • Poor heart healthHigh blood pressure, high cholesterol, and smoking increase the risk of dementia if not treated properly.
  • Traumatic brain injuryHead injuries can increase the risk of dementia, especially if they are severe or occur repeatedly.

Early Symptoms Of Dementia

Overview

Dementia is a collection of symptoms that can occur due to a variety of possible diseases. Dementia symptoms include impairments in thought, communication, and memory.

If you or your loved one is experiencing memory problems, dont immediately conclude that its dementia. A person needs to have at least two types of impairment that significantly interfere with everyday life to receive a dementia diagnosis.

In addition to difficulty remembering, the person may also experience impairments in:

  • language
  • reasoning

    Lewy Body Dementia & Parkinsons Dementia

    Dementia: Causes, types, symptoms, diagnosis, treatment, and prevention ...

    Lewy Body Dementia is another form of dementia that causes changes in thinking, behavior, and movement. LBD is caused by abnormal deposits of a protein called alpha-synuclein in the brain. These deposits, called Lewy bodies, can lead to problems with thinking, movement, behavior, and mood. For example, symptoms may include changes in alertness and attention, hallucinations, tremor, muscle stiffness, sleep problems, and memory loss.

    The two types of Lewy Body Dementia are:

    • Dementia with Lewy bodies, in which cognitive symptoms appear within a year of movement problems
    • Parkinsons disease dementia, in which cognitive problems develop more than a year after the onset of movement problems

    Lewy body dementia can be hard to diagnose because Parkinsons disease and Alzheimers disease cause similar symptoms. Scientists think that LBD might be related to these diseases, or that they sometimes happen together.

    What treatments are available?

    Beyond medications, its important to stay mentally, socially, and physically active to help with cognition. Learn more about ways to optimize your brain health from AARPs Global Council on Brain Health.Research has shown physical exercise, a heart-healthy diet, limiting alcohol intake, getting good sleep, mood management, and staying socially and mentally active, to all optimize brain health.

    What Are The Treatments For Dementia

    There is no cure for most types of dementia, including Alzheimer’s disease and Lewy body dementia. Treatments may help to maintain mental function longer, manage behavioral symptoms, and slow down the symptoms of disease. They may include:

    • Medicines may temporarily improve memory and thinking or slow down their decline. They only work in some people. Other medicines can treat symptoms such as anxiety, depression, sleep problems, and muscle stiffness. Some of these medicines can cause strong side effects in people with dementia. It is important to talk to your health care provider about which medicines will be safe for you.
    • Occupational therapy to help find ways to more easily do everyday activities
    • Speech therapy to help with swallowing difficulties and trouble speaking loudly and clearly
    • Mental health counseling to help people with dementia and their families learn how to manage difficult emotions and behaviors. It can also help them plan for the future.
    • Music or art therapy to reduce anxiety and improve well-being

    Difficulty Completing Normal Tasks

    A subtle shift in the ability to complete normal tasks may indicate that someone has early dementia. This usually starts with difficulty doing more complex tasks like balancing a checkbook or playing games that have a lot of rules.

    Along with the struggle to complete familiar tasks, they may struggle to learn how to do new things or follow new routines.

    Lewy Body Dementia Vs Parkinsons Disease Dementia

    Signs of dementia

    Diagnoses of Lewy body dementia include dementia with Lewy bodies and Parkinsons disease dementia. Symptoms in both of these diagnoses can be similar.

    Lewy body dementia is a progressive dementia caused by abnormal deposits of a protein called alpha-synuclein in the brain. Lewy bodies are also seen in Parkinsons disease.

    The overlap in symptoms between Lewy body dementia and Parkinsons disease dementia include movement symptoms, rigid muscles, and problems with thinking and reasoning.

    This seems to indicate that they could be linked to the same abnormalities, though more research is needed to confirm that.

    The later stages of Parkinsons disease have more severe symptoms that may require help moving around, around-the-clock care, or a wheelchair. Quality of life can decline rapidly.

    Risks of infection, incontinence, pneumonia, falls, insomnia, and choking increase.

    Hospice care, memory care, home health aides, social workers, and support counselors can be a help in later stages.

    Parkinsons disease itself isnt fatal, but complications can be.

    Research has shown a median survival rate of about

    Causes Of Vascular Dementia

    Vascular dementia is caused by reduced blood supply to the brain due to diseased blood vessels.

    To be healthy and function properly, brain cells need a constant supply of blood to bring oxygen and nutrients. Blood is delivered to the brain through a network of vessels called the vascular system. If the vascular system within the brain becomes damaged – so that the blood vessels leak or become blocked – then blood cannot reach the brain cells and they will eventually die.

    This death of brain cells can cause problems with memory, thinking or reasoning. Together these three elements are known as cognition. When these cognitive problems are bad enough to have a significant impact on daily life, this is known as vascular dementia.

    Symptoms Specific To Dementia With Lewy Bodies

    Dementia with Lewy bodies has many of the symptoms of Alzheimer’s disease, and people with the condition typically also experience:

    • periods of being alert or drowsy, or fluctuating levels of confusion
    • visual hallucinations
    • becoming slower in their physical movements
    • repeated falls and fainting

    What Happens In Dementia

    Dementia

    People with dementia may have different symptoms, depending on the type and stage of their particular dementia. A persons symptoms depend on which part of the brain is affected by the disease process, and they may change over time as the diseases progress to involve different areas of the brain. Different types of dementia tend to target particular parts of the brain. For example, the part of the brain that is important for the formation of new memories is usually affected early on in AD, which is why short-term memory loss is often one of the first symptoms of AD. Other common symptoms in dementia include difficulties with communication, planning and organization, navigation, personality changes, and psychiatric symptoms such as depression, anxiety, delusions and hallucinations.

    Parkinsons Disease Dementia And Dementia With Lewy Bodies

    The key pathological hallmark found in brains of Parkinsons disease and Parkinsons disease dementia patients are abnormal microscopic deposits composed of alpha-synuclein. This protein is found widely in the brain but its normal function is not yet well understood. The deposits are called Lewy bodies. Lewy bodies are also found in several other neurodegenerative brain disorders, including dementia with Lewy bodies . Evidence suggests that Parkinsons disease and Parkinsons disease dementia, and dementia with Lewy bodies, may be linked to the same underlying abnormalities in brain processing of alpha-synuclein.

    We all sometimes forget the day of the week or where we are going momentarily but people with dementia can become lost in familiar places such as the road they live in, forget where they are or how they got there, and not know how to get back home. Someone who has dementia may also confuse night and day.

    What Happens In The Early Stage Of Dementia

    Dementia affects everyone differently and early symptoms are often relatively mild and not always easy to notice.

    Many people at the early stage of dementia stay largely independent and only need a bit of assistance with daily living. It is important to focus on what the person can do and not to take over and do things for them. Instead, try doing things with them, for example helping the person develop a routine, reminder lists and prompts, and use technology.

    Symptoms In The Later Stages Of Dementia

    As dementia progresses, memory loss and difficulties with communication often become severe. In the later stages, the person is likely to neglect their own health, and require constant care and attention.

    The most common symptoms of advanced dementia include:

    • memory problems people may not recognise close family and friends, or remember where they live or where they are
    • communication problems some people may eventually lose the ability to speak altogether. Using non-verbal means of communication, such as facial expressions, touch and gestures, can help
    • mobility problems many people become less able to move about unaided. Some may eventually become unable to walk and require a wheelchair or be confined to bed
    • behavioural problems a significant number of people will develop what are known as “behavioural and psychological symptoms of dementia”. These may include increased agitation, depressive symptoms, anxiety, wandering, aggression, or sometimes hallucinations
    • bladder incontinence is common in the later stages of dementia, and some people will also experience bowel incontinence
    • appetite and weight loss problems are both common in advanced dementia. Many people have trouble eating or swallowing, and this can lead to choking, chest infections and other problems. Alzheimer’s Society has a useful factsheet on eating and drinking
