Who Can Diagnose Dementia

What is 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.

Managing Movement Problems In Ftd

Medications and physical and occupational therapy may provide modest relief for the movement symptoms of FTD. A doctor who specializes in these disorders can guide treatment.

For people with corticobasal syndrome, Parkinsons disease medicines may offer some temporary improvement. Physical and occupational therapy may help the person move more easily. Speech therapy can help them manage language symptoms.

For people with progressive supranuclear palsy, sometimes Parkinsons disease drugs provide temporary relief for slowness, stiffness, and balance problems. Exercises can keep the joints limber, and weighted walking aids such as a walker with sandbags over the lower front rung can help maintain balance. Speech, vision, and swallowing difficulties usually do not respond to any drug treatment. Antidepressants have shown modest success. For people with abnormal eye movements, bifocals or special glasses called prisms are sometimes prescribed.

People with FTD-ALS typically decline quickly over two to three years. During this time, physical therapy can help treat muscle symptoms, and a walker or wheelchair may be useful. Speech therapy may help a person speak more clearly at first. Later on, other ways of communicating, such as a speech synthesizer, can be used. The ALS symptoms of the disorder ultimately make it impossible to stand, walk, eat, and breathe on ones own.

Relatives In Need Of Support

The category Relatives in need of support depicts the physiotherapists pedagogical approach in contact with relatives. The participants felt that they had an important role in spreading information about dementia and they wanted to contribute to an increased understanding among relatives, who were described as a party to support . As physiotherapists they felt that they could support relatives by explaining how the persons behavior could be a symptom of dementia and they experienced that their tutoring/education of relatives could contribute to reduced frustration between family members. Specific physiotherapeutic measures, such as testing of walking aids, sometimes had to wait.

For me, the pedagogical approach is to to give the right conditions to understand if I want to inform or instruct a patient or a relative or a staff, I must do it with the right conditions for the person concerned to understand what I want to have said

Relatives were often experienced as learning by seeing the physiotherapist do in contact with the person with dementia. Seeing the physiotherapist succeeding in communicating in a way adapted to the person with dementia could inspire relatives to try to do the same.

What Is Dementia Definition Description And Diagnosis

The World Health Organization figures show that 50 million people worldwide are affected by dementia, with 10 million new cases diagnosed every year. Dementia disease has become a major challenge throughout the world. When it affects you or someone close to you, the problem becomes even more real for you. The first thing you need to know is a complete answer to the question ‘What is dementia?’

Communicating About Dementia With Health Care Providers

Dementia vs Alzheimer

Good communication with the primary care provider affects the well-being of the person with dementia as well as the well-being of the caregiver. Communicating your concerns clearly and describing the changes you may have observed will help guide the provider to investigate further. In some cases, you may find yourself âeducatingâ medical staff about your loved oneâs symptoms.

It is important that your concerns are taken seriously, and you are treated with respect and dignity. If you are not receiving the attention you need, you should communicate your concerns to the provider and request a referral to a resource in the community that specializes in the evaluation of people experiencing cognitive changes. The goal is to establish a partnership to both maintain the quality of health and to solve problems.

Psychological And Psychosocial Therapies

Psychological therapies for dementia include some limited evidence for reminiscence therapy , some benefit for cognitive reframing for caretakers, unclear evidence for validation therapy and tentative evidence for mental exercises, such as cognitive stimulation programs for people with mild to moderate dementia. Offering personally tailored activities may help reduce challenging behavior and may improve quality of life. It is not clear if personally tailored activities have an impact on affect or improve for the quality of life for the caregiver.

Adult daycare centers as well as special care units in nursing homes often provide specialized care for dementia patients. Daycare centers offer supervision, recreation, meals, and limited health care to participants, as well as providing respite for caregivers. In addition, home care can provide one-to-one support and care in the home allowing for more individualized attention that is needed as the disorder progresses. Psychiatric nurses can make a distinctive contribution to people’s mental health.

Some London hospitals found that using color, designs, pictures and lights helped people with dementia adjust to being at the hospital. These adjustments to the layout of the dementia wings at these hospitals helped patients by preventing confusion.

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.

What Causes Vascular Dementia

Vascular dementia is caused by different conditions that interrupt the flow of blood and oxygen supply to the brain and damage blood vessels in the brain.

People with vascular dementia almost always have abnormalities in the brain that can be seen on MRI scans. These abnormalities can include evidence of prior strokes, which are often small and sometimes without noticeable symptoms. Major strokes can also increase the risk for dementia, but not everyone who has had a stroke will develop dementia.

Other abnormalities commonly found in the brains of people with vascular dementia are diseased small blood vessels and changes in “white matter” the connecting “wires” of the brain that are critical for relaying messages between brain regions.

Stage : Mild Dementia

What is dementia?

At this stage, individuals may start to become socially withdrawn and show changes in personality and mood. Denial of symptoms as a defense mechanism is commonly seen in stage 4. Behaviors to look for include:

  • Difficulty remembering things about one’s personal history
  • Disorientation
  • Difficulty recognizing faces and people

In stage 4 dementia, individuals have no trouble recognizing familiar faces or traveling to familiar locations. However, patients in this stage will often avoid challenging situations in order to hide symptoms or prevent stress or anxiety.

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.

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.

Behavioral And Mood Symptoms Of Lewy Body Dementia

Changes in behavior and mood are possible in LBD and may worsen as the persons thinking abilities decline. These changes may include:

  • Depression
  • Apathy, or a lack of interest in normal daily activities or events and less social interaction
  • Anxiety and related behaviors, such as asking the same questions over and over or being angry or fearful when a loved one is not present
  • Agitation, or restlessness, and related behaviors, such as pacing, hand wringing, an inability to get settled, constant repeating of words or phrases, or irritability
  • Delusions, or strongly held false beliefs or opinions not based on evidence. For example, a person may think his or her spouse is having an affair or that relatives long dead are still living.
  • Paranoia, or an extreme, irrational distrust of others, such as suspicion that people are taking or hiding things

Some have called for greater nuance and a more cautious approach to thinking about long COVID, worried that, without clear, diagnostic tests, some symptoms are being misattributed to SARS-CoV-2. One psychiatry intern at Mukherjees own university once characterized long COVID as largely an invention of vocal patient activist groups, helped along by uncritical media coverage. Some studies have found that people who report symptoms dont always have evidence of antibodies against SARS-CoV-2. The long COVID thing, Sir John Bell, a Canadian immunologist and regius professor of medicine at the University of Oxford, told Times Radio, has been slightly overblown, and as soon as you do proper epidemiological studies you find the incidence is much, much lower.

Most Of The Dementias Are Mixed Dementias

The literature reports a 3.4 to 73% overlapping between AD and VaD , -. This overlapping makes difficult to estimate to which extent each disease contributes to the cognitive decline. In fact, the majority of the subjects older than 65 years do have some degree of AD-type changes and cerebrovascular lesions. Several studies demonstrated that cerebrovascular lesions lower the threshold of AD-type changes necessary to cause cognitive decline , -. The burden of vascular and AD-type lesions are considered to be independent of each other, and are consistent with an additive or synergistic effect, but this effect could not be measurable so far

What Is The Definition Of Dementia For The Purposes Of Making A Diagnosis

Classic symptoms of dementia include memory loss, changes to personality and mood, loss of language skills, inability to understand or learn new information, confusion, hallucinations, paranoia, and eventually an inability to manage even the simplest of tasks. However, in order for a patient to be classed as suffering from dementia , the loss of cognitive function must be significant enough to cause major interference with normal life.

Can Dementia Be Prevented

Although dementia cannot be prevented, living a health-focused life might influence risk factors for certain types of dementia. Keeping blood vessels clear of cholesterol buildup, maintaining normal blood pressure, controlling blood sugar, staying at a healthy weight basically, staying as healthy as one can can keep the brain fueled with the oxygen and nutrients it needs to function at its highest possible level. Specific healthful steps you can take include:

  • Follow a Mediterranean diet, which is one filled with whole grains, vegetables, fruits, fish and shellfish, nuts, beans, olive oil and only limited amounts of red meats.
  • Exercise. Get at least 30 minutes of exercise most days of the week.
  • Keep your brain engaged. Solve puzzles, play word games, and try other mentally stimulating activities. These activities may delay the start of dementia.
  • Stay socially active. Interact with people discuss current events keep your mind, heart, and soul engaged.

Medical Definition Of Dementia

What’s the difference between dementia and Alzheimer’s?

Reviewed on 3/29/2021

Dementia: Significant loss of intellectual abilities, such as memory capacity, that is severe enough to interfere with social or occupational functioning. Criteria for the diagnosis of dementia include impairment of attention, orientation, memory, judgment, language, motor and spatial skills, and function. By definition, dementia is not due to major depression or schizophrenia. Alzheimer’s disease is the most common cause of dementia. Other causes include AIDS, alcoholism, brain injury, vascular dementia , dementia with Lewy bodies, brain tumors, drug toxicity, infection of brain, Creutzfeldt-Jakob disease, meningitis, Pick disease, syphilis, and hypothyroidism.

What Is Vascular Dementia

Vascular dementia is a form of dementia that develops because of problems with the bloods circulation to the brain. It causes problems with reasoning, planning, judgement, memory and other thinking.

Vascular dementia is the second most common form of dementia after Alzheimers disease. People with vascular dementia tend to decline more rapidly than people with Alzheimers disease.

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 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 .

Social Activities And The Risk Of Alzheimer’s Disease

What is Dementia

Alzheimer’s disease is a disease that affects 5.8 million people in the US. 80% are 75 years old or older. Around 50 million people worldwide have dementia, and between 60 and 70% have Alzheimer’s disease.

It is difficult to juggle finances, balance checkbooks and pay bills on time. A person with Alzheimer’s may be unable to deal with numbers. Alzheimer’s causes a decline in the ability to make decisions.

A person may make poor choices in social interactions or wear clothes that are inappropriate for the weather. It may be more difficult to respond to everyday problems, such as food burning on the stove. Skills are not lost even when symptoms get worse.

Skills that are preserved include reading, listening, singing, listening to music, dancing, drawing, and doing crafts. A number of conditions can cause memory loss or other dementia symptoms. If you are worried about your memory or other thinking skills, you should talk to your doctor.

Increasing age is the most common risk factor for Alzheimer’s disease. Alzheimer’s is not normal aging, but it is more likely to occur as you get older. People with MCI have a higher risk of dementia.

Why It’s Important To Get A Diagnosis

Although there is no cure for dementia at the moment, an early diagnosis means its progress can be slowed down in some cases, so the person may be able to maintain their mental function for longer.

A diagnosis helps people with dementia get the right treatment and support. It can also help them, and the people close to them, to prepare for the future.
