Diagnosing Lewy Body Dementia: For Professionals
Lewy body dementia can be difficult to diagnose. Talking to both patients and caregivers helps doctors make a diagnosis. It is important to ask the patient and their care partners about any symptoms involving thinking, movement, sleep, behavior, or mood. Certain medications can worsen LBD symptoms be aware of all current medications and supplements the patient is taking.
Dementia with Lewy bodies is often hard to diagnose because its early symptoms may resemble those of Alzheimer’s disease or a psychiatric illness. As a result, it is often misdiagnosed or missed altogether. As additional symptoms appear, making an accurate diagnosis may become easier.
The good news is that doctors are increasingly able to diagnose LBD earlier and more accurately, as researchers identify which symptoms and biomarkers help distinguish it from similar disorders.
Visiting a family doctor is often the first step for people who are experiencing changes in thinking, movement, or behavior. If a persons primary doctor is not familiar with LBD, they may have patients seek second opinions from specialists, like a geriatric psychiatrist, neuropsychologist, or a geriatrician to help diagnose LBD. If a specialist cannot be found in your community, ask the neurology department at a nearby medical school for a referral. Neurologists generally have the expertise needed to diagnose LBD.
Difficult as it is, getting an accurate diagnosis of LBD early on is important so that a person:
Treatment And Care For Lewy Body Dementia
While LBD currently cannot be prevented or cured, some symptoms may respond to treatment for a period of time. An LBD treatment plan may involve medications, physical and other types of therapy, and counseling. A plan to make any home safety updates and identify any equipment can make everyday tasks easier.
A skilled care team often can suggest ways to improve quality of life for both people with LBD and their caregivers.
Is Alzheimers Diagnosed With A Blood Test
The other biomarker test, uses either a blood sample or, more commonly, a cerebral spinal fluid sample. The CSF sample is obtained via a spinal tap.
We look for markers of Alzheimers disease in the blood and the spinal fluid samples. These are pieces of the plaques and tangles that might be circulating in the blood or spinal fluid.
Therefore, the patient can have a thinking and memory test, and then typically the physician will add on additional tests. One could be a PET scan of the brain and the other one could be a test of either the blood or cerebral spinal fluid.
Diagnosing Alzheimers disease is a process. And its typically a combination of these three approaches: Cognitive Testing, PET biomarkers and fluid either blood or spinal biomarkers.
In all cases, personal results are compared to norms. The person is compared to other healthy people in the population that are approximately just like them. Neurologists look at the levels of all of the things that they are measuring to determine if they think its Alzheimers disease.
And thats how a diagnosis goes.

Early Symptoms Of Dementia
Although the early signs vary, common early symptoms of dementia include:
- memory problems, particularly remembering recent events
- increasing confusion
- apathy and withdrawal or depression
- loss of ability to do everyday tasks.
Sometimes, people fail to recognise that these symptoms indicate that something is wrong. They may mistakenly assume that such behaviour is a normal part of the ageing process. Symptoms may also develop gradually and go unnoticed for a long time. Also, some people may refuse to act, even when they know something is wrong.
Managing Sleep Disorders In Lewy Body Dementia
Sleep problems may increase confusion and behavioral problems in people with LBD and add to a caregiver’s burden. A physician can order a sleep study to identify any underlying sleep disorders such as sleep apnea, restless leg syndrome, and REM sleep behavior disorder.
REM sleep behavior disorder, a common LBD symptom, involves acting out one’s dreams, leading to lost sleep and even injuries to individuals and their sleep partners. Clonazepam, a drug used to control seizures and relieve panic attacks, is often effective for the disorder at very low dosages. However, it can have side effects such as dizziness, unsteadiness, and problems with thinking. Melatonin, a naturally occurring hormone used to treat insomnia, may also offer some benefit when taken alone or with clonazepam.
Excessive daytime sleepiness is also common in LBD. If it is severe, a sleep specialist may prescribe a stimulant to help the person stay awake during the day.
Some people with LBD have difficulty falling asleep. If trouble sleeping at night persists, a physician may recommend a prescription medication. It is important to note that treating insomnia and other sleep problems in people with LBD has not been extensively studied, and that treatments may worsen daytime sleepiness and should be used with caution. Sleep problems can also be addressed by avoiding lengthy naps, increasing daytime exercise, and avoiding caffeine, alcohol, and chocolate late in the day.

Who Is This Dementia Quiz For
Below is a list of 9 questions composed for people who are concerned about memory loss. The questions relate to life experiences common among people who have symptoms of dementia, currently known as Neurocognitive Disorder , and are based on criteria in the DSM-5.
The following questions encompass the six domains of cognition that are evaluated when assessing symptoms NCD: executive functioning, complex attention, perceptual-motor ability, social interactions, learning/memory-related difficulties, and challenges involving daily activities.
Please read each question carefully, and indicate how often you have experienced the same or similar challenges in the past few months.
The Future Of Ftd Treatment
Researchers are continuing to explore the biological changes in the body, including genetic mutations and proteins, that lead to FTD and identify and test possible new drugs and other treatments. They are also developing better ways to track disease progression, so that treatments, when they become available, can be directed to the right people. Clinical trials and studies are underway to advance these efforts. People with FTD and healthy people may be able to participate. To find out more, talk to your health care provider or visit the Alzheimers.gov Clinical Trials Finder.

Lewy Body Dementia: Symptoms Can Be Mistaken For Other Disorders
Diagnosing Lewy body dementia is especially complicated because its symptoms are similar to those of Alzheimers, Parkinsons disease, or a psychiatric illness.
As a way to distinguish Lewy body dementia from other brain disorders, researchers are studying a number of methods, including the use of lumbar puncture to measure proteins in cerebrospinal fluid.
Cognitive decline is one of the essential criteria for a diagnosis of Lewy body dementia. In addition, two or more of the following are required:
- Fluctuating, unpredictable alertness and ability to think
- Repeated visual hallucinations
- Parkinsonian symptoms, such as physical rigidity
- REM sleep behavior disorder, in which patients act out their dreams while asleep
Physicians may also look for the presence of certain biomarkers and conduct other tests to assess brain function. These include:
- Tests that assess blood vessels in the heart to measure nerve function
- Sleep studies that evaluate brain waves
The presence of the following symptoms may also indicate Lewy body dementia:
- Problems with autonomic nervous system function, as indicated by unstable blood pressure and heart rate, poor regulation of body temperature, and sweating
- Excessive daytime sleepiness
- Loss of the sense of smell
To rule out other conditions with symptoms resembling those of Lewy body dementia, such as Parkinsons disease, strokes, and tumors, doctors might conduct neurological and physical exams that assess:
- Reflexes
- Sense of touch
Neurologists: Do Seniors With Alzheimer’s Need One

Dementia Diagnosis At Dignity Health
Doctors diagnose dementia by performing specialized neurological exams and obtaining a thorough family medical history. Your doctor will assess your attention span, memory, ability to solve simple problems, and performance on similar tasks. A comprehensive neuropsychology exam is usually part of diagnosing dementia. Certain imaging and lab tests can be helpful when diagnosing dementia. They improve the likelihood of pinpointing the type of dementia and can rule out other causes of dementia-like symptoms. Tests may include:
- Positron emission tomography scan
- Magnetic resonance imaging scan
- Blood tests
A dementia diagnosis relies on identifying loss of brain function, so it can take time as doctors wait for the disease to progress. Dignity Health provides compassionate care and support for dementia symptoms in Arizona.
Types Of Lewy Body Dementia
It’s important to know which type of LBD a person has, both to tailor treatment to particular symptoms and to understand how the disease will likely progress. Clinicians and researchers use the “one-year rule” to help make a diagnosis. If cognitive symptoms appear at the same time as or at least a year before movement problems, the diagnosis is dementia with Lewy bodies. If cognitive problems develop more than a year after the onset of movement problems, the diagnosis is Parkinson’s disease dementia.
Regardless of the initial symptoms, over time, people with either type of LBD often develop similar symptoms, due to the presence of Lewy bodies in the brain. But there are some differences. For example, dementia with Lewy bodies may progress more quickly than Parkinson’s disease dementia.

S Doctors Take To Diagnose Dementia
Doctors typically go through 5 areas of evaluation to figure out whether or not someone has dementia. The doctor needs to check each area and document what they find.
1. Difficulty with mental functionsThis is usually evaluated with a combination of an office-based cognitive test and finding out about real-world problems by talking with their patient and people close to them.
2. Decline from previous level of abilityThis can be more difficult for a doctor to determine, so they need to talk with people who know the patient well to understand their previous abilities versus what they can do today.
For example, if a former accountant can no longer do basic math, thats a decline from their previous ability.
3. Impairment of daily life functionThis can also be tough for doctors to evaluate on their own.
So, the doctor will ask people close to their patient about what types of help the person is getting in their daily life and what problems family members have noticed.
4. Reversible causes of cognitive impairmentCertain conditions can cause temporary dementia-like symptoms.
Delirium can seem like Alzheimers or dementia and is usually caused by illness, infections, or a hospitalization and can last from weeks to months.
Other medical problems that interfere with thinking skills include medication side effects, thyroid problems, electrolyte imbalances, B12 deficiency, substance abuse, and other treatable health conditions.
Movement Problems And Lewy Body Dementia
Some people with LBD may not experience significant movement problems for several years. Others may have them early on. At first, movement symptoms, such as a change in handwriting, may be very mild and easily overlooked. Movement problems may include:
- Muscle rigidity or stiffness

Who Diagnoses Dementia
The General Practitioner is usually the first contact when concerns about thinking or memory arise. The GP will take a medical history and may carry out a brief test of memory and concentration. If the GP is concerned about the possibility of dementia, the person may be referred to a specialist or specialist memory centre. It is important to remember that the choice of doctor is up to you so if after your visit you are still concerned and wish a referral to a specialist, you may wish to ask for a second opinion.
Specialists such as neurologists, geriatricians, psychogeriatricians, psychiatrists, and neuropsychologists have a more detailed knowledge of the memory and behaviour changes associated with dementia and may perform or arrange in-depth assessments, brain scans and blood tests. In Australia, a specialist must confirm the diagnosis of Alzheimers disease in order for you to be eligible for subsidised Alzheimers medications.
Aged Care Assessment Teams are multidisciplinary teams often comprised of social workers, occupational therapists, as well as nurses and doctors. ACATs are usually based in hospitals or regional community health centres. ACATs assess the health needs of ageing individuals, put the individual in contact with relevant services, make recommendations about the level of care required and approve eligibility for certain services.
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.
In addition, medical conditions such as stress, anxiety, depression, and delirium can cause serious memory problems that resemble dementia, as can side effects of certain medicines.
Researchers have also identified many other conditions that can cause dementia or dementia-like symptoms. These conditions include:

What To Do If A Doctor Jumps To A Diagnosis In A Single Visit
Unfortunately, some doctors do jump quickly to a dementia diagnosis in only one visit. Even worse, they dont properly document what led to their decision.
If this happens, you may want to seek a second opinion from a doctor who is willing and able to do more thorough evaluation and testing.
Yes, there is a chance that your older adults symptoms could mean that they have dementia.
Thats why an accurate diagnosis is essential for proper treatment.
Much Of The Promising Research Is In Neurology
Since this disease is a brain disorder, it stands to reason that some of the most promising research findings come from the field of neurology. For example, in a recent study, neuroscientists found that a certain type of light therapy reversed the advance of Alzheimers in mice.
Only a neurologist is likely to know about research projects like this and how they might impact your loved ones health. If you have questions about current research, a neurologist may be the best person to answer them.

Vascular Dementia: Causes Symptoms And Treatments
Vascular dementia refers to changes to memory, thinking, and behavior resulting from conditions that affect the blood vessels in the brain. Cognition and brain function can be significantly affected by the size, location, and number of vascular changes.
Symptoms of vascular dementia can begin gradually or can occur suddenly, and then progress over time, with possible short periods of improvement. Vascular dementia can occur alone or be a part of a different diagnosis such as Alzheimer’s disease or other forms of dementia. When an individual is diagnosed with vascular dementia, their symptoms can be similar to the symptoms of Alzheimer’s.
Main Findings And Comparison With Previous Studies
All doctors in the study clearly named dementia. Doctors deployed specific strategies to make the diagnosis clear to patients, but often downplayed or avoided prognosis. Doctors elicited patient orientation to the purpose of the meeting. This has not been described in work examining the structure of primary care consultations,Reference Robinson23 indicating that orientation is generally assumed in primary care but not in memory clinics. Over 60% of patients showed some uncertainty about the meeting purpose, which may be because patients have non-medical symptom explanations or companions are more proactive in seeking help.Reference Samsi, Abley, Campbell, Keady, Manthorpe and Robinson24 Additionally, as shown in extract 2, patients may not be informed as to the purpose of the diagnostic meeting. When patients do not expect a diagnosis, this can lead to more distressReference Robinson, Gemski, Abley, Bond, Keady and Campbell25 and difficulty accepting the diagnosis and its consequences.Reference Bunn, Sworn, Brayne, Iliffe, Robinson and Goodman26 Hence, eliciting orientation and forecasting the diagnosis prior to diagnosis delivery is important. However, guidelines advocate patient preferences for information should be ascertained prior to the diagnostic feedback meeting.Reference Guss27 Given that in 20% of meetings the doctors were asking if patients wanted to know the diagnosis immediately prior to delivery, this may not be happening in practice.
