Symptoms Specific To Vascular Dementia

How long does dementia last?

Vascular dementia is the second most common cause of dementia, after Alzheimer’s. Some people have both vascular dementia and Alzheimer’s disease, often called “mixed dementia”.

Symptoms of vascular dementia are similar to Alzheimer’s disease, although memory loss may not be as obvious in the early stages.

Symptoms can sometimes develop suddenly and quickly get worse, but they can also develop gradually over many months or years.

Specific symptoms can include:

  • stroke-like symptoms: including muscle weakness or temporary paralysis on one side of the body
  • movement problems difficulty walking or a change in the way a person walks
  • thinking problems having difficulty with attention, planning and reasoning
  • mood changes depression and a tendency to become more emotional

How Long Do Dementia Patients Live After Diagnosis

Dementia symptoms typically progress slowly. People with dementia will progress from mild to severe dementia at varying speeds and may be diagnosed earlier or later in life. Some people with dementia may live for up to 20 years after their diagnosis, though according to the Alzheimer’s Association research shows that the average person lives for four to eight years after a diagnosis of dementia. It’s important to point out that the diagnosis of dementia is often missed, delayed, or diagnosed when the illness is moderate or advanced. The impact of that variable may not be accurately reflected in the research regarding the years of life post-diagnosis.

What Are Causes Of Dementia

There are a number of causes of dementia. In general, dementia is more frequent with increasing age. Alzheimer’s disease is the most common form of dementia. Among other causes are Lewy Body Dementia, vascular dementia, dementia related to Parkinson’s Disease, frontotemporal lobar degeneration , and dementias caused by other medical conditions as well as brain injury, strokes, multiple sclerosis, infection of the brain , HIV infection, fluid build-up in the brain , Pick’s disease, and brain tumors.

How Is Dementia Different From Normal Ageing

Many of us get a little more forgetful as we get older. Most people will need a bit longer to remember things, get distracted more easily or struggle to multi-task as well as they once did. This may become noticeable particularly from middle age – usually taken as during our 40s, 50s and early 60s – onwards.

These changes are normal, but they can be a nuisance and at times frustrating. However, you may worry that these things are an early sign of dementia. It’s important not to worry too much about this. For most people, these changes will be the result of normal ageing and won’t be down to dementia.

Women Over 90 More Likely To Have Dementia Than Men

University of California – Irvine
Summary:
Women over 90 are significantly more likely to have dementia than men of the same age, according UC Irvine researchers involved with the 90+ Study, one of the nation’s largest studies of dementia and other health factors in the fastest-growing age demographic.

Women over 90 are significantly more likely to have dementia than men of the same age, according UC Irvine researchers involved with the 90+ Study, one of the nation’s largest studies of dementia and other health factors in the fastest-growing age demographic.

The researchers reviewed an analysis of 911 people enrolled in the 90+ Study. Of those, 45 percent of the women had dementia, as opposed to 28 percent of the men. The analysis did not determine when the subjects first experienced dementia.

The 90-plus age group, or the “oldest old,” is the fastest growing segment of the population, according to the U.S. Census. While there are currently nearly 2 million nonagenarians in the U.S. alone, that number is projected to increase to 10 to 12 million by the middle of the century, raising concerns that the current health care system may not be able to accommodate this population.

“Our findings show that more will need to be done to provide adequate resources to care for the increasing number of very old people with dementia,” said Maria Corrada, a UC Irvine epidemiologist and study corresponding author.

Reversible Causes Of Memory Loss

Its important to remember that memory loss doesnt automatically mean that you have dementia. There are many other reasons why you may be experiencing cognitive problems, including stress, depression, and even vitamin deficiencies. Thats why its so important to go to a doctor to get an official diagnosis if youre experiencing problems.

Sometimes, even what looks like significant memory loss can be caused by treatable conditions and reversible external factors, such as:

Depression. Depression can mimic the signs of memory loss, making it hard for you to concentrate, stay organized, remember things, and get stuff done. Depression is a common problem in older adultsespecially if youre less social and active than you used to be or youve recently experienced a number of important losses or major life changes .

Vitamin B12 deficiency. Vitamin B12 protects neurons and is vital to healthy brain functioning. In fact, a lack of B12 can cause permanent damage to the brain. Older people have a slower nutritional absorption rate, which can make it difficult for you to get the B12 your mind and body need. If you smoke or drink, you may be at particular risk. If you address a vitamin B12 deficiency early, you can reverse the associated memory problems. Treatment is available in the form of a monthly injection.

What Are The Symptoms Of Early

For most people with early-onset Alzheimer disease, the symptoms closely mirror those of other forms of Alzheimer disease.

Early symptoms:

  • Withdrawal from work and social situations

  • Changes in mood and personality

Later symptoms:

  • Severe mood swings and behavior changes

  • Deepening confusion about time, place, and life events

  • Suspicions about friends, family, or caregivers

  • Trouble speaking, swallowing, or walking

  • Severe memory loss

Symptoms Of Mild Cognitive Impairment

How to get a diagnosis of dementia?

Mild cognitive impairment is an intermediate stage between normal age-related cognitive changes and the more serious symptoms that indicate dementia.

MCI can involve problems with memory, language, thinking, and judgment that are greater than normal age-related changes, but the line between MCI and normal memory problems is not always a clear one. The difference is often one of degrees. For example, its normal as you age to have some problems remembering the names of people. However, its not normal to forget the names of your close family and friends and then still be unable to recall them after a period of time.

If you have mild cognitive impairment, you and your family or close friends will likely be aware of the decline in your memory or mental function. But, unlike people with full-blown dementia, you are still able to function in your daily life without relying on others.

While many people with MCI eventually develop Alzheimers disease or another type of dementia, that doesnt mean its inevitable. Some people with MCI plateau at a relatively mild stage of decline while others even return to normal. The course is difficult to predict, but in general, the greater the degree of memory impairment, the greater your risk of developing dementia some time in the future.

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.

What Is Younger Onset Dementia

Younger onset dementia is used to describe any form of dementia that develops in people under the age of 65. Dementia has been diagnosed in people in their 50s, 40s and even in their 30s. It is sometimes called early onset dementia.

Younger onset dementia is similar to other types of dementia in many ways. The same problems generally occur, but the disease can have a different impact on a younger person because they are more likely to be employed full time, raising a family or financially responsible for a family.

Problem Solving Or Planning Difficulties

The person may find that they have difficulty following directions, solving problems, and focusing. For example, they may find it difficult to:

  • follow a recipe
  • follow directions on a product
  • keeping track of monthly bills or expenses

Some people often have problems like these, but if they start to happen when they did not happen before, it could indicate early onset Alzheimers disease.

Symptoms Specific To Frontotemporal Dementia

Warning Signs of Dementia and How to Prevent Them ...

Although Alzheimer’s disease is still the most common type of dementia in people under 65, a higher percentage of people in this age group may develop frontotemporal dementia than older people. Most cases are diagnosed in people aged 45-65.

Early symptoms of frontotemporal dementia may include:

  • personality changes reduced sensitivity to others’ feelings, making people seem cold and unfeeling
  • lack of social awareness making inappropriate jokes or showing a lack of tact, though some people may become very withdrawn and apathetic
  • language problems difficulty finding the right words or understanding them
  • becoming obsessive such as developing fads for unusual foods, overeating and drinking

What Causes Dementia To Progress So Quickly

Dementia symptoms are typically mild at first and progress over time to moderate and then severe, over several years. The speed as which dementia progresses varies between individuals, but some factors can cause dementia to progress more quickly. These include the persons age, the type of dementia, and other long term health problems. Dementia tends to progress more slowly in people over 65 compared to younger people below 65.

Facts About The Future

Studies into the main types of dementia have revealed the following about life expectancy

Alzheimers disease

General life expectancy for someone with Alzheimers is around 8-12 years from diagnosis although this does depend on age and health. If you were relatively fit and healthy on the diagnosis you could live considerably longer than this. People who are diagnosed around the age of 65 tend to decline more slowly than those who are aged 80 or over. But with the right care and treatment, a fit and healthy 80 year old could still live into their nineties.

Did you know? A US study of 1,300 men and women with Alzheimers showed life expectancy to range from one year to 26 years from when their symptoms first appeared

Vascular dementia

Since vascular dementia is often linked to strokes people who are living with it can be in poorer general health than those with other types of dementia. Studies have shown their average life expectancy to be around four years after diagnosis, though their eventual decline is often linked to further strokes.

Dementia with Lewy bodies

After diagnosis, the average lifespan of someone with dementia with Lewy bodies was found in one study to be around 5-7 years after onset. However people have been known to live between two and 20 years with it, depending on their age, and other medical conditions they may have, such as Parkinsons disease which can be related to dementia with Lewy bodies.

A Person With Dementia Doesnt Always Fit Into One Stage

Dementia affects each person in a unique way and changes different parts of the brain at different points in the disease progression.

Plus, different types of dementia tend to have different symptoms.

For example, someone with frontotemporal dementia may first show extreme behavior and personality changes. But someone with Alzheimers disease would first experience short-term memory loss and struggle with everyday tasks.

Researchers and doctors still dont know enough about how these diseases work to predict exactly what will happen.

Another common occurrence is for someone in the middle stages of dementia to suddenly have a clear moment, hour, or day and seem like theyre back to their pre-dementia abilities. They could be sharp for a little while and later, go back to having obvious cognitive impairment.

When this happens, some families may feel like their older adult is faking their symptoms or just isnt trying hard enough.

Its important to know that this isnt true, its truly the dementia thats causing their declining abilities as well as those strange moments of clarity theyre truly not doing it on purpose.

How Is Dementia Treated

Dementia treatment is directed toward managing symptoms, and identifying whether or not there may be a reversible cause. Medicines such as acetylcholinesterase inhibitors can sometimes help to slow the progression of cognitive changes, but quite often the effects of medicines are only modest and cannot prevent eventual worsening of the underlying condition. Agitation and other emotional concerns are generally addressed as part of the overall treatment plan.

What Is Dementia And What Are The Symptoms

Dementia is the term for a group of symptoms that occur when the brain is damaged by diseases. This includes Alzheimer’s disease or diseases of the blood vessels that can cause a stroke. These diseases can cause a significant decline in a person’s mental abilities or ‘cognitive function’ – our capacity for things like memory, thinking and reasoning.

For a doctor to diagnose dementia, a person’s symptoms must have become bad enough to significantly affect their daily life, not just be an occasional minor irritation. This means having new problems with everyday activities about the house, in the community or at work. For example, starting to have problems paying household bills, using the phone, managing medicines, driving safely or meeting up with friends.

If a person has symptoms that are worse than would normally be expected for a healthy person their age, but are not severe enough to significantly affect their daily life, a doctor may diagnose mild cognitive impairment . This is not a type of dementia, though some people who have MCI will go on to develop dementia.

What Happens After A Diagnosis Of Younger Onset Dementia

Dementia

A diagnosis of younger onset dementia can come as a shock. The person affected, and their family and friends may all feel angry or sad. They might not believe it. There can be a huge sense of loss. These feelings are normal.

But help and support is available, and it is better to get it earlier than later.

Younger people with dementia need to think about several issues.

The Truth About Aging And Dementia

As we age, our brains change, but Alzheimers disease and related dementias are not an inevitable part of aging. In fact, up to 40% of dementia cases may be prevented or delayed. It helps to understand whats normal and whats not when it comes to brain health.

Normal brain aging may mean slower processing speeds and more trouble multitasking, but routine memory, skills, and knowledge are stable and may even improve with age. Its normal to occasionally forget recent events such as where you put your keys or the name of the person you just met.

In the United States, 6.2 million people age 65 and older have Alzheimers disease, the most common type of dementia. People with dementia have symptoms of cognitive decline that interfere with daily lifeincluding disruptions in language, memory, attention, recognition, problem solving, and decision-making. Signs to watch for include:

Alzheimer’s disease or related dementias are not an inevitable part of aging. There are 7 ways to help maintain your brain health.

  • Not being able to complete tasks without help.
