Support For Family And Friends
Currently, many people living with Alzheimers disease are cared for at home by family members. Caregiving can have positive aspects for the caregiver as well as the person being cared for. It may bring personal fulfillment to the caregiver, such as satisfaction from helping a family member or friend, and lead to the development of new skills and improved family relationships.
Although most people willingly provide care to their loved ones and friends, caring for a person with Alzheimers disease at home can be a difficult task and may become overwhelming at times. Each day brings new challenges as the caregiver copes with changing levels of ability and new patterns of behavior. As the disease gets worse, people living with Alzheimers disease often need more intensive care.

Stage : Mild Cognitive Impairment
Clear cognitive problems begin to manifest in stage 3. A few signs of stage 3 dementia include:
- Getting lost easily
- Noticeably poor performance at work
- Forgetting the names of family members and close friends
- Difficulty retaining information read in a book or passage
- Losing or misplacing important objects
- Difficulty concentrating
Patients often start to experience mild to moderate anxiety as these symptoms increasingly interfere with day to day life. Patients who may be in this stage of dementia are encouraged to have a clinical interview with a clinician for proper diagnosis.
What Is Dementia Symptoms Types And Diagnosis
Dementia is the loss of cognitive functioning thinking, remembering, and reasoning to such an extent that it interferes with a persons daily life and activities. Some people with dementia cannot control their emotions, and their personalities may change. Dementia ranges in severity from the mildest stage, when it is just beginning to affect a persons functioning, to the most severe stage, when the person must depend completely on others for basic activities of living.
Dementia is more common as people grow older but it is not a normal part of aging. Many people live into their 90s and beyond without any signs of dementia.
There are several different forms of dementia, including Alzheimers disease. A persons symptoms can vary depending on the type.

Common Forms Of Dementia
There are many different forms of dementia. Alzheimers 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.

Types Of Alzheimer’s Disease
Nearly everyone with Alzheimerâs disease will eventually have the same symptoms — memory loss, confusion, trouble with once-familiar tasks, and making decisions. While the manner of the disease development remains unclear, all forms of Alzheimer’s appear to share overproduction and/or decreased clearance of a type of protein called amyloid beta peptides. Though the effects of the disease are similar, there are two main types.
- Early-onset Alzheimer’s. This type happens to people who are younger than age 65. Often, theyâre in their 40s or 50s when theyâre diagnosed with the disease. Itâs rare — up to 5% of all people with Alzheimer’s have early-onset. People with Down syndrome have a higher risk for it.Scientists have found a few ways in which early-onset Alzheimerâs is different from other types of the disease. People who have it tend to have more of the brain changes that are linked with Alzheimerâs. The early-onset form also appears to be linked with a defect in a specific part of a personâs DNA: chromosome 14. A form of muscle twitching and spasm, called myoclonus, is also more common in early-onset Alzheimer’s.
- Late-onset Alzheimer’s. This is the most common form of the disease, which happens to people age 65 and older. It may or may not run in families. So far, researchers havenât found a particular gene that causes it. No one knows for sure why some people get it and others donât.

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
- Alzheimers 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.
- Alzheimers 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 With Parkinsonism
One form of familial FTD, also known as frontotemporal dementia with Parkinsonism-17 , is caused by genetic changes in the gene for tau protein, located on chromosome 17. No other risk factors for this condition are known.
FTDP-17 is rare and accounts for only three per cent of all cases of dementia. Symptoms progressively get worse over time and usually appear between the ages of 40 and 60. The condition affects both thinking and behavioural skills and movements such as rigidity, lack of facial expression and problems with balance .
It can be distressing to be told that you have a genetic disorder or are at risk of having one. Genetic counselling provides the person and their family with information about a genetic disorder and its likely impact on their lives. This can assist a person with FTDP-17 to make informed medical and personal decisions about how to manage their condition and the challenges it presents to their health and wellbeing. Prenatal genetic counselling is also available for parents to help them decide about a pregnancy that may be at risk of FTDP-17.

What Is Alzheimers Disease
- Alzheimers disease is the most common type of dementia.
- It is a progressive disease beginning with mild memory loss and possibly leading to loss of the ability to carry on a conversation and respond to the environment.
- Alzheimers disease involves parts of the brain that control thought, memory, and language.
- It can seriously affect a persons ability to carry out daily activities.
Medications To Treat The Underlying Alzheimers Disease Process
Aducanumab is the first disease-modifying therapy approved by the FDA to treat Alzheimers disease. The medication helps to reduce amyloid deposits in the brain and may help slow the progression of Alzheimers, although it has not yet been shown to affect clinical outcomes such as progression of cognitive decline or dementia. A doctor or specialist will likely perform tests, such as a PET scan or analysis of cerebrospinal fluid, to look for evidence of amyloid plaques and help decide if the treatment is right for the patient.
Aducanumab was approved through the FDAs Accelerated Approval Program. This process requires an additional study after approval to confirm the anticipated clinical benefit. If the follow-up trial fails to verify clinical benefit, the FDA may withdraw approval of the drug. Results of the phase 4 clinical trial for aducanumab are expected to be available by early 2030.
Several other disease-modifying medications are being tested in people with mild cognitive impairment or early Alzheimers as potential treatments.

Researchers Define Six Types Of Alzheimers Disease Why That Matters To You
A new study suggests the underlying biology of Alzheimers may be different for patients with different symptoms.
A study that analyzed the interplay of Alzheimers symptoms and genetic differences has found evidence for six subtypes of the deadly dementia.
The findings are important because they provide evidence that treatments that may work for some patients might not help others with a different genetic profile. This has implications for clinical trials the tested drug may look less effective if many study subjects dont have the right kind of dementia and could eventually lead to more personalized treatment. Genetic differences are a sign that the biological underpinnings of symptoms may be different and thus could respond to different medications.
What we are saying is that there is a lot of heterogeneity in Alzheimers, said Shubhabrata Mukherjee, a research assistant profession in general internal medicine at the University of Washington School of Medicine who led the study. You cannot label everyone with Alzheimers disease and say thats it.
The new study was published this month in Molecular Psychiatry. Mukherjees team included researchers from several other institutions, including the University of Pittsburgh.
This is sort of a first step in trying to understand the heterogeneity of Alzheimers disease, said Oscar Lopez, a neurologist who heads the University of Pittsburgh Medical Centers Alzheimers Disease Research Center.
Stage : Moderate Dementia
Patients in stage 5 need some assistance in order to carry out their daily lives. The main sign for stage 5 dementia is the inability to remember major details such as the name of a close family member or a home address. Patients may become disoriented about the time and place, have trouble making decisions, and forget basic information about themselves, such as a telephone number or address.
While moderate dementia can interfere with basic functioning, patients at this stage do not need assistance with basic functions such as using the bathroom or eating. Patients also still have the ability to remember their own names and generally the names of spouses and children.

How Long Can A Person Live With Alzheimers Disease
The time from diagnosis to death varies as little as three or four years if the person is older than 80 when diagnosed, to as long as 10 or more years if the person is younger.
Alzheimers disease is currently ranked as the sixth leading cause of death in the United States, but recent estimates indicate that the disorder may rank third, just behind heart disease and cancer, as a cause of death for older people.
Currently, there is no cure for Alzheimers disease, though there has been significant progress in recent years in developing and testing new treatments. Several medicines have been approved by the U.S. Food and Drug Administration to treat people with Alzheimers.
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.

Stage : Age Associated Memory Impairment
This stage features occasional lapses of memory most frequently seen in:
- Forgetting where one has placed an object
- Forgetting names that were once very familiar
Oftentimes, this mild decline in memory is merely normal age-related cognitive decline, but it can also be one of the earliest signs of degenerative dementia. At this stage, signs are still virtually undetectable through clinical testing. Concern for early onset of dementia should arise with respect to other symptoms.
Managing Alzheimer’s Disease Behavior
Common behavioral symptoms of Alzheimers include sleeplessness, wandering, agitation, anxiety, and aggression. Scientists are learning why these symptoms occur and are studying new treatments drug and nondrug to manage them. Research has shown that treating behavioral symptoms can make people with Alzheimers more comfortable and makes things easier for caregivers.

What Are Related Dementias
When you talk about Alzheimers disease, you might hear people refer to Alzheimers disease and related dementias. Related dementias include vascular dementia, Lewy body dementia, frontotemporal lobe dementia and Creutzfeldt-Jakob disease. We call these related dementias because their symptoms are similar to the symptoms of Alzheimers disease. Alzheimers disease and related dementias are also grouped together because theyre all caused by changes in the brain that cant be stopped.
- Vascular dementia is the second-most common type of dementia. Its caused by problems with blood supply to the brain and is often the result of a stroke.
- Lewy body dementia is a type of dementia caused by changes in the nerve cells of the brain.
- Frontotemporal dementia is a group of diseases and changes that affect only certain parts of the brain.
- Creutzfeldt-Jakob disease changes the structure of brain tissue and causes a very rare type of dementia.
For more information on these related dementias, contact the Alzheimer Society of BC or talk to your doctor.
How Is Alzheimers Disease Treated
Alzheimers is complex, and it is therefore unlikely that any one drug or other intervention will successfully treat it in all people living with the disease.
Scientists are exploring many avenues to delay or prevent the disease as well as to treat its symptoms. In ongoing clinical trials, scientists are developing and testing several possible interventions. Under study are drug therapies aimed at a variety of disease interventions, as well as nondrug approaches such as physical activity, diet, cognitive training, and combinations of these. Just as we have many treatments for heart disease and cancer, we will likely need many options for treating Alzheimers. Precision medicine getting the right treatment to the right person at the right time will likely play a major role.
Current approaches to treating Alzheimers focus on helping people maintain mental function, treating the underlying disease process, and managing behavioral symptoms.

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.
How Many Americans Have Alzheimers Disease
Estimates vary, but experts suggest that more than 6 million Americans age 65 and older may have Alzheimers. Many more under age 65 also have the disease. Unless Alzheimer’s can be effectively treated or prevented, the number of people with it will increase significantly if current population trends continue. This is because increasing age is the most important known risk factor for Alzheimers disease.

What Causes Early
Experts don’t know what triggers the start of Alzheimer disease. They suspect that 2 proteins damage and kill nerve cells. Fragments of one protein, beta-amyloid, build up and are called plaques. Twisted fibers of another protein, tau, are called tangles. Almost everyone develops plaques and tangles as they age. But those with Alzheimer disease develop many, many more. At first, these plaques and tangles damage the memory areas of the brain. Over time, they affect more areas of the brain. Experts don’t know why some people develop so many plaques and tangles, or how they spread and damage the brain.
