There Are Five Different Types Of Dementia
What Are The Signs And Symptoms Of Dementia
Many people associate dementia with memory loss. This is because memory problems are often one of the early symptoms of a dementia disorder, but they are not the only one. The symptoms of dementia can vary, depending on the type of dementia and what areas of the brain are affected. Symptoms may include:
- Memory loss, poor judgment, and confusion
- Changes in the ability to speak, understand, and express thoughts and/or words and to write and read
- Wandering and getting lost in a familiar neighborhood
- Trouble handling money and paying bills
- Repeating questions
- Using unusual words to refer to familiar objects
- Taking longer to complete normal daily tasks
- Loss of interest in normal daily activities or events
- Hallucinations, delusions, and paranoia
Is Alzheimers Disease Genetic
In general terms the answer is no. When there is a high prevalence of dementia in a family it tends to be down to similar lifestyle choices or other physical health issues that increase the risk. There are however some exceptionally rare forms of Alzheimers disease where there is a direct genetic link and affects people under the age of 60.

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.
What Causes Alzheimers Disease
In recent years, scientists have made tremendous progress in better understanding Alzheimers and the momentum continues to grow. Still, scientists dont yet fully understand what causes Alzheimers disease in most people. In people with early-onset Alzheimers, a genetic mutation may be the cause. Late-onset Alzheimers arises from a complex series of brain changes that may occur over decades. The causes probably include a combination of genetic, environmental, and lifestyle factors. The importance of any one of these factors in increasing or decreasing the risk of developing Alzheimers may differ from person to person.

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.
Is There Treatment Available
At present there is no cure for Alzheimer’s disease. However, one group of drugs called cholinergeric drugs appears to be providing some temporary improvement in cognitive functioning for some people with mild to moderate Alzheimer’s disease.
Drugs can also be prescribed for secondary symptoms such as restlessness or depression or to help the person with dementia sleep better.
Community support is available for the person with Alzheimer’s disease, their families and carers. This support can make a positive difference to managing dementia. Dementia Australia provides support, information and counselling for people affected by dementia. Dementia Australia also aims to provide up-to-date information about drug treatments.

Global Incidence And Prevalence Of Dat
Data documenting the incidence of DAT indicate that it is a global problem that will become more severe as the population ages. summarizes population-based studies estimating the incidence and prevalence of DAT. Studies from different parts of the world were selected if they were population based and large. The estimates from the Delphi Consensus Study are for dementia rather than DAT but were included because prevalence/incidence estimates were generated from a systematic review of population-based studies. Regardless of country of origin, age-specific incidence rates of DAT increase exponentially with advancing age. In the United States, the incidence rate of DAT is 1 per 1,000 person-years among individuals aged 6064 years and 25 per 1,000 person-years among those older than age 85 years . Although DAT is not a normal part of the aging process, the prevalence of DAT also increases with advancing age. While less than 1 percent of individuals aged 6064 years are deemed to be affected, it is estimated that up to 40 percent of those over the age of 85 years have the condition . Similar trends were observed in a population-based European study of persons aged 65 years or older. The age-standardized prevalence of DAT was 4.4 percent, and the prevalence increased with age .
Common Forms Of Dementia
There are many different forms of dementia. Alzheimer’s disease is the most common form and may contribute to 6070% of cases. Other major forms include vascular dementia, dementia with Lewy bodies , and a group of diseases that contribute to frontotemporal dementia . The boundaries between different forms of dementia are indistinct and mixed forms often co-exist.

Support For Families And Alzheimer’s Disease Caregivers
Caring for a person with Alzheimers can have significant physical, emotional, and financial costs. The demands of day-to-day care, changes in family roles, and decisions about placement in a care facility can be difficult. NIA supports efforts to evaluate programs, strategies, approaches, and other research to improve the quality of care and life for those living with dementia and their caregivers.
Becoming well-informed about the disease is one important long-term strategy. Programs that teach families about the various stages of Alzheimers and about ways to deal with difficult behaviors and other caregiving challenges can help.
Good coping skills, a strong support network, and respite care are other things that may help caregivers handle the stress of caring for a loved one with Alzheimers. For example, staying physically active provides physical and emotional benefits.
Some caregivers have found that joining a support group is a critical lifeline. These support groups enable caregivers to find respite, express concerns, share experiences, get tips, and receive emotional comfort. Many organizations sponsor in-person and online support groups, including groups for people with early-stage Alzheimers and their families.

Risk Factors And Prevention
Although age is the strongest known risk factor for dementia, it is not an inevitable consequence of 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 dementia by getting regular exercise, 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, low educational attainment, social isolation, and cognitive inactivity.

Health Environmental And Lifestyle Factors
Research suggests that a host of factors beyond genetics may play a role in the development and course of Alzheimers. There is a great deal of interest, for example, in the relationship between cognitive decline and vascular conditions such as heart disease, stroke, and high blood pressure, as well as conditions such as diabetes and obesity. Ongoing research will help us understand whether and how reducing risk factors for these conditions may also reduce the risk of Alzheimers.
A nutritious diet, physical activity, social engagement, and mentally stimulating pursuits have all been associated with helping people stay healthy as they age. These factors might also help reduce the risk of cognitive decline and Alzheimers. Researchers are testing some of these possibilities in clinical trials.
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.

Correlates Of More Rapid Cognitive Decline In Dat
Progressive cognitive decline is the principal clinical manifestation of DAT, and a faster rate of decline is strongly associated with mortality . The rates at which people decline, however, differ substantially between affected persons, are difficult to predict, and are still not well understood .
The APOE 4 allele, a strong genetic risk factor for DAT, is associated with a greater risk of developing DAT . Earlier age at onset is observed in a dose-dependent fashion . These findings have led to the hypothesis that APOE 4 allele carriers may experience a more rapid degenerative process regarding development of DAT and that cognitive decline should progress more rapidly in these patients , but studies have provided conflicting evidence on whether the APOE 4 allele is associated with an accelerated rate of cognitive decline .
What To Do If You Suspect Alzheimers Disease
Getting checked by your healthcare provider can help determine if the symptoms you are experiencing are related to Alzheimers disease, or a more treatable conditions such as a vitamin deficiency or a side effect from medication. Early and accurate diagnosis also provides opportunities for you and your family to consider financial planning, develop advance directives, enroll in clinical trials, and anticipate care needs.

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.
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.

Icipating In Alzheimer’s Disease Clinical Trials
Everybody those with Alzheimers disease or MCI as well as healthy volunteers with or without a family history of Alzheimers may be able to take part in clinical trials and studies. Participants in Alzheimers clinical research help scientists learn how the brain changes in healthy aging and in Alzheimers. Currently, at least 270,000 volunteers are needed to participate in more than 250 active clinical trials and studies that are testing ways to understand, diagnose, treat, and prevent Alzheimers disease.
Volunteering for a clinical trial is one way to help in the fight against Alzheimers. Studies need participants of different ages, sexes, races, and ethnicities to ensure that results are meaningful for many people.
NIA leads the federal governments research efforts on Alzheimers. NIA-supported Alzheimers Disease Research Centers throughout the U.S. conduct a wide range of research, including studies of the causes, diagnosis, and management of the disease. NIA also sponsors the Alzheimers Clinical Trials Consortium, which is designed to accelerate and expand studies and therapies in Alzheimers and related dementias.

What Are The 4 Main Types Of Dementia
4.8/5Four 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.
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.
- Frontotemporal Dementia.
- Mixed Dementia.
Also Know, what is the most aggressive form of dementia? Alzheimer’s disease is the most common type of dementia. Between 60 and 80 percent of cases of dementia are caused by this disease, according to the Alzheimer’s Association. Early signs of Alzheimer’s disease include depression, forgetting names and recent events, and depressed mood.
Keeping this in consideration, how many different types of dementia are there?
There are over 400 different types of dementia, the most common of which are Alzheimer’s disease and vascular dementia. There are over 400 different types of dementia. The most common types are Alzheimer’s disease and vascular dementia.
What is the most common form of dementia?
Most Common Types of Dementia
- Alzheimer’s Disease â AD is the most common type of dementia.
- Vascular or Multi-Infarct Dementia â This type of dementia is often the result of a stroke in which small areas of the brain are irreversibly damaged.

The Effects Of Alzheimers On The Brain
Damage to the brain begins years before symptoms appear. Abnormal protein deposits form plaques and tangles in the brain of someone with Alzheimers disease. Connections between cells are lost, and they begin to die. In advanced cases, the brain shows significant shrinkage.
Its impossible to diagnose Alzheimers with complete accuracy while a person is alive. The diagnosis can only be confirmed when the brain is examined under a microscope during an autopsy. However, specialists are able to make the correct diagnosis up to 90 percent of the time.
The symptoms of Alzheimers and dementia can overlap, but there can be some differences.
Both conditions can cause:
- behavioral changes
- difficulty speaking, swallowing, or walking in advanced stages of the disease
Some types of dementia will share some of these symptoms, but they include or exclude other symptoms that can help make a differential diagnosis. Lewy body dementia , for example, has many of the same later symptoms as Alzheimers. However, people with LBD but are more likely to experience initial symptoms such as visual hallucinations, difficulties with balance, and sleep disturbances.
People with dementia due to Parkinsons or Huntingtons disease are more likely to experience involuntary movement in the early stages of the disease.
Treatment for dementia will depend on the exact cause and type of dementia, but many treatments for dementia and Alzheimers will overlap.
Annual Report To Parliament On Canada’s Dementia Strategy
Each year the federal Minister of Health prepares a report to Parliament on the national dementia strategy.
