How Does A Doctor Test For Dementia
There is no single diagnostic test for Alzheimers disease and other causes of dementia. Dementias are diagnosed by evaluating and understanding a persons memory and thinking patterns. Doctors will consider a persons memory, grasp of language, mood states, problem-solving skills, ability to maintain focus and perform complex tasks. Evaluation may include in-office cognitive screening , physical examination, and review of labs. Labwork helps to determine whether there are vitamin deficiencies or hormonal changes at play. In some cases, evaluation may require neuropsychological testing, brain imaging , and genetic testing.
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.
Do I Have Dementia The Ultimate List Of Dementia Tests
Every 3 seconds, there’s someone who develops dementia around the world. This is according to the Annual World Alzheimer’s Report. Memory loss tests are everywhere. At times, it is being self-administered. But, when do one consult an expert?
more than one mixed dementia.
Furthermore, dementia symptoms are commonly caused by many things. Even more, there are side effects from medications, depression, thyroid problems, vitamin deficiencies and alcohol abuse. Read more about types of dementia here.

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 person’s 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 person’s 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.
Types Of Tests For Dementia
The first type of tests are called mental status scales.
These are short bedside tests administered by the doctor that assess memory and other cognitive domains.
They provide a score, which is used to distinguish people with normal vs. impaired cognition and even screen for mild cognitive impairment .
Examples of the most widely used include the Montreal Cognitive Assessment and the Mini-Mental State Examination .
These are screening tests, meaning they are not diagnostic of any particular dementia or diagnosis, but when abnormal definitely can hint that cognition is impaired.
Moreover, these tests can be repeated over time to track the progression of the disease as well.
These tests assess memory, language, executive function, visuospatial skills, and attention/concentration.
The MMSE is scored on a 30 point scale. Specific items include orientation , memory , attention/concentration , language , and visuospatial function . A score of < 23 is abnormal and indicates cognitive impairment.
Note: you can find only MMSE test here.
The MOCA is also scored on a 30 point scale.
It assesses delayed word recall/memory , visuospatial function , language , attention/concentration , and orientation . A score of < 25 is abnormal and indicates significant cognitive impairment.
Note: you can also access MOCA test online.
Another similar test is the Saint Louis University Mental Status Examination which is scored similarly.

What Are The Most Common Types Of Dementia
- Alzheimers disease. This is the most common cause of dementia, accounting for 60 to 80 percent of cases. It is caused by specific changes in the brain. The trademark symptom is trouble remembering recent events, such as a conversation that occurred minutes or hours ago, while difficulty remembering more distant memories occurs later in the disease. Other concerns like difficulty with walking or talking or personality changes also come later. Family history is the most important risk factor. Having a first-degree relative with Alzheimers disease increases the risk of developing it by 10 to 30 percent.
- Vascular dementia. About 10 percent of dementia cases are linked to strokes or other issues with blood flow to the brain. Diabetes, high blood pressure and high cholesterol are also risk factors. Symptoms vary depending on the area and size of the brain impacted. The disease progresses in a step-wise fashion, meaning symptoms will suddenly get worse as the individual gets more strokes or mini-strokes.
- Lewy body dementia. In addition to more typical symptoms like memory loss, people with this form of dementia may have movement or balance problems like stiffness or trembling. Many people also experience changes in alertness including daytime sleepiness, confusion or staring spells. They may also have trouble sleeping at night or may experience visual hallucinations .
Know The Signs Of Dementia
Early diagnosis can help people with dementia plan for the future, and might mean they can access interventions that help slow down the disease. Being familiar with the signs of dementia can help people receive a diagnosis as early as possible.
Early signs that a person might have dementia can include:
- being vague in everyday conversations
- memory loss that affects day-to-day function
- short term memory loss
- difficulty performing everyday tasks and taking longer to do routine tasks
- losing enthusiasm or interest in regular activities
- difficulties in thinking or saying the right words
- changes in personality or behaviour
- finding it difficult to follow instructions
- finding it difficult to follow stories
- increased emotional unpredictability.

Dementia Tests Available Online
In contrast to Alzheimers and other brain diseases, conditions often may be reversed with treatment. Most importantly, early diagnosis is crucial to effective treatment and prevention. WebMD reveals that theres no single test that will tell a doctor if you have dementia. Its actually an ongoing process. Example, you may have several of the following, then your doctor will pull information and make a diagnosis. Therefore, there are various dementia tests made available online:
1. MiniMental State Examination or Folstein test
- A 30-point questionnaire that includes simple questions and problems in a number different mental abilities, including a person’s memory, attention and language.
- Notably, it is considered the most commonly used by practitioners.
- Also, health experts use this in clinical research settings for cognitive measurements.
2. Self-Administered Gerocognitive Examination test
- A 15-question written exam that could help with the early detection of Alzheimers disease.
- Also, it is handwritten and designed to be done at home and can be taken in less than 15 minutes.
- Then, participants bring the result to a physician for a more formal evaluation.
3. The Clock-Drawing test
- A test where the subject is presented with a paper with the instructions to draw a clock.
- Oftentimes, used in combination with other, more thorough screening tests.
4. Test Your Memory test
5. Neurotrack test
At What Age Can You Test Someone For The Signs Of Dementia
There is no one particular age that someone must meet before they can be assessed for signs of dementia, although dementia is more common in people over 65. Early-onset dementia can begin in people who are in their 30s, 40s, and 50s. Diagnosing dementia in its early stages is important as early treatment can slow the progression of symptoms and help to maintain mental functions.

Treatment Options For Dementia
Prescription medications to specifically treat some symptoms of progressive dementias are now available. Although these drugs do not halt the disease or reverse existing brain damage, they can minimize the worsening of symptoms temporarily. This may improve an individuals quality of life, ease the burden on caregivers and delay admission to a nursing home. However, each dementia patient is different, and these drugs are not effective for everyone.
Many people with dementia, particularly those in the early stages, benefit from adhering to a clear daily routine and practicing tasks designed to improve performance in specific aspects of cognitive functioning. For example, using memory aids, such as mnemonics, computerized recall devices or note taking can help seniors maintain their day-to-day lives independently for longer.
Treatment As Dementia Gets Worse
The goal of ongoing treatment for dementia is to keep the person safely at home for as long as possible and to provide support and guidance to the caregivers.
Routine follow-up visits to a health professional are necessary to monitor medicines and the person’s level of functioning.
Eventually, the family may have to consider whether to place the person in a care facility that has a dementia unit.
Taking care of a person with dementia is stressful. If you are a caregiver, seek support from family members or friends. Take care of your own health by getting breaks from caregiving. Counselling, a support group, and adult day care or respite care can help you through stressful times and bouts of burnout.

What Is Mixed 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.
Researchers have also identified many other conditions that can cause dementia or dementia-like symptoms. These conditions include:
Can Dementia Suddenly Get Worse
The progression of dementia depends on the underlying disease. Some diseases have a rapid progression. Others progress more slowly. Any sudden change with either slow or rapid progression should be evaluated for another cause. In most cases, changes with dementia may seem like they came out of the blue when they actually may have been slowly developing in the background. The best way to prepare for changes and manage expectations is through information. Your doctor and medical team will be a valuable resource. There are a variety of educational resources that are also available through the Alzheimer’s Association.

Is Dementia Treatable
First, its important to understand the difference in the terms treatable, reversible, and curable. All or almost all forms of dementia are treatable, in that medication and supportive measures are available to help manage symptoms in patients with dementia. However, most types of dementia remain incurable or irreversible and treatment results in only modest benefits.
Some dementias disorders, however, may be successfully treated, with patient returning to normal after treatment. These dementias are ones caused by:
- Side effects of medications or illicit drugs alcohol
- Tumors that can be removed
- Subdural hematoma, a buildup of blood beneath the outer covering of the brain that is caused by a head injury
- Normal pressure hydrocephalus, a buildup of cerebral spinal fluid in the brain
- Metabolic disorders, such as a vitamin B12 deficiency
- Hypothyroidism, a condition that results from low levels of thyroid hormones
- Hypoglycemia, a condition that results from low blood sugar
Dementias that are not reversible, but may still be at least partially responsive to medications currently available for memory loss or behavior-based problems include:
- Alzheimer’s disease
- Dementias associated with Parkinson’s disease and similar disorders
- AIDS dementia complex
- Creutzfeldt-Jakob 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.

Why Would Anyone Want An Early Alzheimers Diagnosis
The SAGE test is useful because it helps you understand if your concerns are something to be worried about.
If the results seem to indicate that there could be a problem, you might think theres no point in talking with the doctor because theres no cure for dementia.
The most important is that a treatable condition could be the cause of cognitive impairment. Finding out sooner means getting treatment ASAP to eliminate the cognitive symptoms.
If the cognitive impairment is caused by Alzheimers or dementia, a major benefit is that starting treatment early is far more effective in managing symptoms and delaying progression of the disease.
Planning For The Future
If possible, make decisions while your loved one is able to take part in the decision making. These are difficult but important conversations. Questions include:
- What kind of care does he or she need right now?
- Who will take care of him or her in the future?
- What can the family expect as the disease progresses?
- What kind of financial and legal planning needs to be done?
Education of the family and other caregivers is critical to successfully caring for someone who has dementia. If you are or will be a caregiver, start learning what you can expect and what you can do to manage problems as they arise. For more information, see Home Treatment.

Why Take A Test For Dementia
It is crucial that the symptoms of memory loss are diagnosed as early as possible. This helps to get the best treatment possible. A do at home dementia test can help a person come to terms with the fact that they may be suffering from dementia.
By taking a simple do at home dementia test you should be able to determine if the person may have a problem with their memory. If they show signs if difficut during the test you should encourage them to seek further help fro their GP. There Doctor can then check for problems such as early stages of Alzheimers disease or dementia.
What Causes Dementia
The causes of Alzheimers and related dementias can vary, depending on the types of brain changes that may be taking place. While research has found that some changes in the brain are linked to certain forms of dementia, in most cases, the underlying causes are unknown. Rare genetic mutations may cause dementia in a relatively small number of people.
Although there is no proven prevention, in general, leading a healthy lifestyle may help reduce risk factors that have been associated with these diseases.
