Disproportionate Impact On Women
Globally, dementia has a disproportionate impact on women. Sixty-five percent of total deaths due to dementia are women, and disability-adjusted life years due to dementia are roughly 60% higher in women than in men. Additionally, women provide the majority of informal care for people living with dementia, accounting for 70% of carer hours.
What To Do If A Loved One Is Suspicious Of Having Dementia
- Discuss with loved one. Talk about seeing a medical provider about the observed changes soon. Talk about the issue of driving and always carrying an ID.
- Medical assessment. Be with a provider that you are comfortable with. Ask about the Medicare Annual Wellness exam.
- Family Meeting. Start planning, and gather documents like the Health Care Directive, Durable Power of Attorney for Health Care, Estate Plan.
Risk Factors And Prevention
Although age is the strongest known risk factor for dementia, it is not an inevitable consequence of biological ageing. Further, dementia does not exclusively affect older people young onset dementia accounts for up to 9% of cases. Studies show that people can reduce their risk of cognitive decline and dementia by being physically active, not smoking, avoiding harmful use of alcohol, controlling their weight, eating a healthy diet, and maintaining healthy blood pressure, cholesterol and blood sugar levels. Additional risk factors include depression, social isolation, low educational attainment, cognitive inactivity and air pollution.

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.
The Seven Stages Of Dementia
One of the most difficult things to hear about dementia is that, in most cases, dementia is irreversible and incurable. However, with an early diagnosis and proper care, the progression of some forms of dementia can be managed and slowed down. The cognitive decline that accompanies dementia conditions does not happen all at once – the progression of dementia can be divided into seven distinct, identifiable stages.
Learning about the stages of dementia can help with identifying signs and symptoms early on, as well as assisting sufferers and caretakers in knowing what to expect in further stages. The earlier dementia is diagnosed, the sooner treatment can start.

What Are The Four Most Common Causes Of Dementia
The most common causes of dementia include:
- Degenerative neurological diseases.
- Traumatic brain injuries caused by car accidents, falls, concussions, etc.
- Infections of the central nervous system.
- Long-time alcohol or drug use.
- Certain types of hydrocephalus, a buildup of fluid in the brain.
Furthermore, what are the four most common forms of dementia?
Four Common Types of Dementia
- Alzheimer’s Disease. This is the most common type of dementia.
- Lewy Body Dementia . Lewy Body Dementia is another very common, yet frequently misdiagnosed, or undiagnosed type of dementia.
- Vascular Dementia.
- Fronto Temporal Dementia.
what are the 5 types of dementia? There are five main types of dementia.
- Alzheimer’s Disease. Probably the most known and the most common dementia type, Alzheimer is a consequence of an abnormal shrinkage of the brain.
- Dementia with Lewy Bodies.
Four Common Types Of Dementia
The term dementia is an umbrella term used to describe the symptoms of cognitive impairment. And within the dementia umbrella, there are many different variations Alzheimers included. Most of us average folk dont realize that all dementia is not Alzheimers. In fact, I would venture to say that the regular layman isnt quite sure what the difference between Alzheimers and Dementia is. Dont fret Ill explain it here!
Learning the difference between the varying levels of memory loss can be crucial to know the dos and donts of dealing with behavior challenges. It will also come into play with understanding the levels of care that are available to fit your loved ones needs, so they can live more comfortably.
In this blog we will discuss the Top 4 most common types of Dementia. The good news for you is that at The Kensington, we are very experienced with these areas of Memory Care and more. We welcome everyone!
Yes, there are many, many more types of dementia that are known. There is dementia resulting from years of alcohol misuse. There is dementia associated with Parkinsons Disease. There is dementia that is a result of a traumatic brain injury. All in all, there are over 100 types of dementia being treated and researched today. An accurate diagnosis is critical to the treatment of someone with dementia, for obvious reasons.

The Different Types Of Dementia In The Elderly
Dementia is the general term for memory loss that interferes with someones daily life. Elderly adults 65 years and older are at the highest risk for dementia, but there are cases of early-onset dementia at 30, 40, or 50.
To help you understand more about dementia, here are some common questions and facts about this memory loss disease.
Which Types Of Dementia Are Hereditary
Its true that genes might have a role in dementia, but the patterns of inheritance vary. Environmental and lifestyle factors also greatly affect our chances of developing a particular disease we may have inherited, so an active, healthy lifestyle is important to avoid many types of illness.
With that being said, current research shows that people who have a parent or sibling with Alzheimers are more likely to develop the disease than those who do not. There also is a difference between early-onset and late-onset, with the latter putting individuals at higher risk. Again, this research is still being developed and depends a lot on the health of the individual.
On the other hand, vascular dementia, dementia with Lewy bodies, and fronto-temporal dementia have not yet been linked to genetics in most cases. The genetic factors instead are linked more to the underlying causes of these dementias or the possibility of gene links to other aspects of these conditions. So out of the four common types of dementia, Alzheimers is the type with the most likely genetic link based on current research.

Causes Of Alzheimer’s Disease
Alzheimer’s disease is the most common type of dementia.
Alzheimer’s disease is thought to be caused by the abnormal build-up of 2 proteins called amyloid and tau.
Deposits of amyloid, called plaques, build up around brain cells. Deposits of tau form “tangles” within brain cells.
Researchers do not fully understand how amyloid and tau are involved in the loss of brain cells, but research into this is continuing.
As brain cells become affected in Alzheimer’s, there’s also a decrease in chemical messengers involved in sending messages, or signals, between brain cells.
Levels of 1 neurotransmitter, acetylcholine, are particularly low in the brains of people with Alzheimer’s disease.
Medicines like donepezil increase levels of acetylcholine, and improve brain function and symptoms.
These treatments are not a cure for Alzheimer’s disease, but they do help improve symptoms.
Read more about treatments for dementia.
The symptoms that people develop depend on the areas of the brain that have been damaged by the disease.
The hippocampus is often affected early on in Alzheimer’s disease. This area of the brain is responsible for laying down new memories. That’s why memory problems are one of the earliest symptoms in Alzheimer’s.
Unusual forms of Alzheimer’s disease can start with problems with vision or with language.
Read more about Alzheimer’s disease.
Dementia With Lewy Bodies
Dementia with Lewy bodies, also known as Lewy body dementia, is caused by protein deposits in nerve cells. This interrupts chemical messages in the brain and causes memory loss and disorientation.
People with this type of dementia also experience visual hallucinations and have trouble falling asleep at night or fall asleep unexpectedly during the day. They also might faint or become lost or disoriented.
Dementia with Lewy bodies shares many symptoms with Parkinson and Alzheimer diseases. For example, many people develop trembling in their hands, have trouble walking, and feel weak.

Common Forms Of Dementia
There are many different forms of dementia. Alzheimer’s disease is the most common form and may contribute to 60-70% of cases. Other major forms include vascular dementia, dementia with Lewy bodies , and a group of diseases that contribute to frontotemporal dementia . Dementia may also develop after a stroke or in the context of certain infections such as HIV, harmful use of alcohol, repetitive physical injuries to the brain or nutritional deficiencies. The boundaries between different forms of dementia are indistinct and mixed forms often co-exist.

Dementia: What Are The Main Types
While ageing, the brain encounters significant modifications. For example, from the age of 60, it slowly starts to shrink. Heart diseases and head traumas can also have an important effect on the brain, sometimes causing dementia. A persons family history also influences the occurrence of this kind of syndrome.
Dementia is a significant sign of progressive neurodegeneration. This causes the death of some brain cells as well as tissue loss. The most frequently affected areas are the memory, the thinking, the behaviour and the ability to do some tasks for the sick person.
Continue below to learn what are the five different types of dementia.
Common Types Of Dementia
Most people diagnosed with dementia have one of 4 common types: Alzheimers Disease, Vascular Dementia, Frontotemporal Dementia and Dementia with Lewy Bodies. These types of dementia have slightly different symptoms and causes. You can find out more about each type below, and from our dedicated guides to each of these common types of dementia.

What Types Of Dementia Symptoms Are Most Common
Dementia is a progressive disease, meaning that its symptoms worsen over time. The most common sign of dementia is short-term memory loss, which leads to difficulty remembering:
- Where they place items
In the early stages of most dementias, symptoms arent severe and the individual can still function independently. Family members often have a relatively easy time caring for their loved ones with dementia at this point.
However, as dementia progresses, it can affect the individuals physical abilities, mood, and behavior. Eventually, most people with dementia need around-the-clock care as they lose their ability to dress, eat, and move around independently.
In this late stage of dementia, family members often require professional caregivers to provide care for their loved ones.
What Medications Are Available To Treat Dementia
Drugs approved for the most common form of dementia, Alzheimers disease, are discussed below. These drugs are also used to treat people with some of the other forms of dementia.
- cholinesterase inhibitors
- NMDA receptor antagonist memantine
These two classes of drugs affect different chemical processes in the brain. Both classes have been shown to provide some benefit in improving or stabilizing memory function in some patients. Although none of these drugs appear to stop the progression of the underlying disease, they may slow it down.
If other medical conditions are causing dementia or co-exist with dementia, the appropriate drugs used to treat those specific conditions are prescribed.

Who Can Diagnose Dementia
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.
What Are The Different Types Of Dementia
Various disorders and factors contribute to the development of dementia. Neurodegenerative disorders result in a progressive and irreversible loss of neurons and brain functioning. Currently, there are no cures for these diseases.
The five most common forms of dementia are:
- Alzheimers disease, the most common dementia diagnosis among older adults. It is caused by changes in the brain, including abnormal buildups of proteins, known as amyloid plaques and tau tangles.
- Frontotemporal dementia, a rare form of dementia that tends to occur in people younger than 60. It is associated with abnormal amounts or forms of the proteins tau and TDP-43.
- Lewy body dementia, a form of dementia caused by abnormal deposits of the protein alpha-synuclein, called Lewy bodies.
- Vascular dementia, a form of dementia caused by conditions that damage blood vessels in the brain or interrupt the flow of blood and oxygen to the brain.
- Mixed dementia, a combination of two or more types of dementia.

Four Different Types Of Dementia
Think of dementia as a tree. Dementia is the tree trunk and the branches are the various forms of dementia that extend from the trunk, each with their own set of leaves, representing the signs and symptoms. Each branch is slightly different from one another, but they still belong to the same tree.
This guide will look at four different types of dementia: Alzheimers disease , Vascular Dementia , Lewy Body Dementia , and Frontotemporal Dementia . Youll notice that these types of dementia share similar symptoms, but there are differences in the number of cases, signs, and treatments for each.
How Is Lbd Different From Parkinsons Or Alzheimers
ishonestNo.111 – Purge Impurities
These diseases are similar in a lot of ways. But there are some key differences in the symptoms that affect people with LBD and when those symptoms happen.
LBD may not cause short-term memory loss like Alzheimers. People with both conditions have trouble with thinking, alertness, and paying attention. But in LBD, those problems come and go. The disease can also cause hallucinations, often in the first few years someone has LBD. People with Alzheimers usually dont have hallucinations until the later stages.
People with LBD also often act out their dreams and make violent movements when theyre asleep. Its called REM sleep behavior disorder. Sometimes, its the first sign that someone has LBD.
LBD and Parkinsons disease both cause movement problems, like stiff muscles and tremors. But most people with Parkinsons dont have problems with their thinking and memory until the very later stages of their disease. Sometimes, they dont have it at all. In the type of LBD known as Parkinsons disease with dementia, these problems begin much sooner.
People with LBD also need different drugs for their condition than the ones that treat Parkinsons or Alzheimers.

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
What Is Lewy Body Dementia
Lewy bodies are clumps of protein that can form in the brain. When they build up, they can cause problems with the way your brain works, including your memory, movement, thinking skills, mood, and behavior. These problems can keep you from doing everyday tasks or taking care of yourself, a condition called dementia.
Lewy body dementia is one of the most common types of dementia, after Alzheimers disease. It usually happens to people who are 50 or over. There are two types:
- Dementia with Lewy bodies often starts when you have a hard time moving your body. Within a year, you start to have thinking and memory problems that are similar to Alzheimers disease, along with changes in behavior. You also might see things that arent there, called hallucinations.
- Parkinsons disease dementia first causes movement problems. Trouble with memory happens much later in the disease.
Right now, theres no cure for Lewy body dementia. But there are ways to ease symptoms for a while. Scientists are also getting better at understanding the differences between LBD and other conditions.
