Lewy Body Dementia (LBD) is a type of dementia that can be difficult to diagnose because its symptoms mimic those of other diseases. Part of getting a diagnosis often includes cognitive testing for Lewy Body Dementia, which can help rule out other causes of dementia. It is important to note that there is no definitive test to show Lewy Body Dementia — only during an autopsy can you be sure that a person had LBD.

A diagnosis of Lewy Body Dementia (LBD) can be difficult to confirm because the symptoms often overlap with those of other conditions, such as Parkinson’s disease and Alzheimer’s disease.

There is no single test for diagnosing Lewy Body Dementia (LBD), but cognitive testing can be a helpful tool in making a determination. LBD is characterized by changes in thinking and cognition, which can make cognitive testing especially important in this instance. A person with LBD may experience hallucinations, changes in alertness and attention, and problems with movement. All of these things can impact cognitive functioning.

There are several different types of cognitive tests that can be used to assess someone for LBD. The most common are the Mini-Mental State Examination (MMSE) and the Montreal Cognitive Assessment (MoCA).

What is the Mini-Mental State Examination (MMSE) for Cognitive Testing for Lewy Body Dementia?

The Mini-Mental State Examination (MMSE) is a brief, structured test of mental status that is commonly used to screen for cognitive impairment. It can also be used to track changes in cognition over time.

The MMSE has 30 items that cover five areas of cognitive function: orientation, attention and calculation, recall, language, and visuospatial ability. The test takes about 10-15 minutes to administer.

A person’s score on the MMSE can range from 0 to 30, with higher scores indicating better cognitive function. A score of 24 or below is generally considered to be indicative of cognitive impairment.

What is the Montreal Cognitive Assessment (MoCA)?

The Montreal Cognitive Assessment, or MoCA, is a cognitive test that was developed in 1996 by Dr. Ziad Nasreddine. The test is designed to assess a person’s cognitive functioning and is often used to screen for dementia. The MoCA has become one of the most widely used cognitive tests in the world and has been translated into over 50 languages.

The MoCA consists of 30 items that assess a range of cognitive domains, including attention, executive function, visuospatial ability, language, and memory. The test takes about 10-15 minutes to administer and can be administered by a trained professional or caregiver. A person’s score on the MoCA can range from 0 to 30, with higher scores indicating better cognitive functioning.

There is evidence to suggest that the MoCA is an effective tool for screening for dementia.

What is Neuropsychological-Psych Testing?

There are a number of different neuro-psych tests that may be used in the diagnosis of LBD. Some of the most common include tests of memory, attention, language, and visuospatial skills. The specific tests used will depend on the individual patient’s symptoms and medical history.

A neuropsychological assessment can help to diagnose Lewy Body Dementia and track the progression of the disease. During a neuropsychological assessment, patients are typically given a battery of tests that assess different cognitive domains. For example, tests of memory and executive function can help to identify areas of impairment in people with LBD. The results of a neuropsychological assessment can help to guide treatment decisions and support patients and their caregivers. This type of testing can help to identify changes in thinking, memory, and other cognitive skills. It can also help to rule out other possible causes of these changes.

Clock Test for Cognitive Testing for Lewy Body Dementia

The clock test is a cognitive assessment that is used to determine an individual’s ability to process and remember information. It is often used to diagnose dementia or other cognitive impairments. The test consists of showing the person a clock face and asking them to describe what they see. The person is then asked questions about the time on the clock, such as what time it is, or what the hands are pointing to. The test is scored based on the number of correct answers given. A score of 0-5 is considered normal, while a score of 6 or more is considered impaired.

A common task used to assess cognitive functioning is the drawing of a clock. This task can be used to measure a variety of cognitive skills, including visuospatial ability, executive functioning, and memory. This ability refers to one’s ability to perceive and process visual information. The test requires participants to draw a clock from memory, without the aid of a template or other reference material. It can also be used to assess executive functioning. Executive functioning refers to higher-level cognitive skills that are required for planning, problem-solving, and self-regulation.

Real-Life Experience of Drawing a Clock for Cognitive Testing for Lewy Body Dementia

My husband has been asked numerous times to draw a clock to assess his cognitive function. I was shocked the first time that he couldn’t accurately do it. The numbers were mainly at the top of the circle and none of them were in the right place. He was still functioning quite well at that time so I was taken completely off-guard.


How to Get Someone to have Cognitive Testing

If you notice your loved one is struggling with memory loss or changes in mood or behavior, it’s time to have a conversation about getting cognitive testing. In the Lewy Body Dementia world there are often big objections to any sort of testing, or even going to any doctor appointments.

It can be difficult to persuade someone to get cognitive testing or go to the doctor, but there are some things you can do to help. First, try to have a conversation with the person about their concerns and explain why you think it’s important for them to get tested. Timing is everything so choose the right time to talk about it. Avoid bringing up the subject when your loved one is tired, hungry, or already feeling overwhelmed. Instead, pick a time when they are relaxed and likely to be receptive to information and discussion.

Be patient and understanding. It can be difficult for someone with dementia to understand what’s happening to them, so be prepared to explain things slowly and clearly. If they’re still resistant, you could try offering to go with them to their appointment or even just doing some research together on the best options for testing.

What Do the Results of These Tests Mean?

Cognitive testing can help doctors assess a patient’s executive functioning, which includes abilities like planning and organization. Patients with LBD often have difficulty with these tasks. While cognitive testing may not be able to definitively diagnose LBD, it can give doctors valuable information about a patient’s cognitive abilities and help them rule out other possible causes of dementia. Cognitive testing can help to diagnose Lewy body dementia, as well as to identify which patients are likely to progress to more severe stages of the disease. The results of cognitive testing may also help to predict how a person with Lewy body dementia will respond to treatment.


In conclusion, cognitive testing is an important tool for diagnosing Lewy Body Dementia. While there is no definitive test for the disease, cognitive testing can help to rule out other potential causes of dementia and provide a more accurate diagnosis. Early diagnosis is important for initiating treatment and providing support to patients and their families.
