How Is Vascular Dementia Diagnosed
In addition to a complete medical history and physical exam, your healthcare provider may order some of the following:
- Computed tomography . This imaging test uses X-rays and a computer to make horizontal, or axial images of the brain. CT scans are more detailed than general X-rays.
- FDG-PET scan. This is a PET scan of the brain that uses a special tracer to light up regions of the brain.
- Electroencephalogram . This test measures electrical activity in the brain
- Magnetic resonance imaging . This test uses large magnets, radiofrequencies, and a computer to make detailed images of the brain.
- Neuropsychological assessments. These tests can help sort out vascular dementia from other types of dementia and Alzheimer’s.
- Neuropsychiatric evaluation. This may be done to rule out a psychiatric condition that may resemble dementia.
Causes And Risk Factors
The most significant predictor of developing major neurocognitive disorder is age.
Major neurocognitive disorder may be caused by a variety of factors noted in the DSM-5 as specifiers. These specifiers are:
- multiple etiologies
Females have a higher risk of developing a major neurocognitive disorder, especially Alzheimers disease. This may be because females live longer on average than males.
Major neurocognitive disorder is not currently curable. However, some treatments can alleviate symptoms or slow the progression of cognitive decline.
Treatment is mainly dependent on the specific cause.
In some cases, cognitive training may help improve cognition or slow down the progression of symptoms. This non-pharmacological treatment uses guided practices to improve memory, problem-solving, or attention. This type of skills training focuses on the improvement of specific cognitive functions.
One study in 2018 examined the pharmacological treatments of major neurocognitive disorders.
The researchers recommended that non-pharmacological treatments should be the first line of treatment for major neurocognitive disorders due to the risks and side effects linked with antipsychotics, such as mortality from stroke, myocardial infarction, or infection.
Doctors often prescribe antipsychotics as a treatment for major neurocognitive disorders.
Standard antipsychotics that can be effective for symptoms include:
Vascular Dementia Signs And Symptoms
Vascular dementia affects different people in different ways and the speed of the progression also varies from person to person. Some symptoms may be similar to those of other types of dementia and usually reflect increasing difficulty to perform everyday activities like eating, dressing, or shopping.
Behavioral and physical symptoms can come on dramatically or very gradually, although it appears that a prolonged period of TIAsthe mini-strokes discussed aboveleads to a gradual decline in memory, whereas a bigger stroke can produce profound symptoms immediately. Regardless of the rate of appearance, vascular dementia typically progresses in a stepwise fashion, where lapses in memory and reasoning abilities are followed by periods of stability, only to give way to further decline.

Relation Of Affect Ratings And White Matter Changes
The next phase of data analysis examined the relation of affect ratings to semiquantitative ratings from neuroimaging depicting varying degrees of white matter disease. All subjects with neuroimaging data were included in these analyses. Analyses were similar to those used to compare diagnostic groups. Firstly, a multivariate general linear model was used in which the four component scores were dependent variables. White matter disease was the primary independent variable, and sex, age, education, and MMSE were also included as secondary independent variables. The overall white matter disease effect was significant, =3.6 p< 0.008 Wilk’s lambda=0.95), so individual ANOVAs were performed with each of the four component scores. Figure shows the relation between white matter disease ratings and component scores. Component score means were calculated for patients with white matter disease ratings of 0, 1, 2, and 3 and these means and standard errors are presented in fig.

Affect Rating Differences Between Alzheimer’s Disease And Ischaemic Vascular Dementia
The first step of data analysis involved comparing patients with probable Alzheimer’s disease with patients in the ischaemic vascular dementia group . Table shows demographic characteristics of patients in these groups. Groups did not significantly differ in age, education, MMSE scores, or sex.

ANOVAs were then performed for each dependent variable using the same five independent variables . Significant Alzheimer’s disease-ischaemic vascular disease group differences were noted for component 1 , with these characteristics present to a greater degree in in patients with ischaemic vascular dementia. Demographic variables and MMSE were not significantly related to this component. Component 4 showed highly significant Alzheimer’s disease-ischaemic vascular disease differences, , with significantly slower psychomotor speed for the ischaemic vascular disease group. Sex =32.8 p< 0.002 M female=-0.18, M male=-0.63) and MMSE effects were also significant. Alzheimer’s disease-ischaemic vascular disease effects for the two other dependent variables were not significant.

What Can You Do
A healthy lifestyle is important to help reduce risk factors of vascular dementia. This includes eating well, limiting alcohol, not smoking, exercising, and managing stress.
If you are concerned about vascular dementia symptoms, talk with your doctor. If you or someone you know has recently been diagnosed, explore the resources on this website and linked below to find out more about the disease, care, support, and research.
The Progressively Lowered Stress Threshold Model
The Progressively Lowered Stress Threshold model aims at decreasing environmental stress and thereby decreasing some behavioral disturbances in dementia patients. Caregivers who receive PLST training report fewer secondary behavioral symptoms in patients than do caregivers who do not receive such training. The PLST model identifies 6 triggers of behavioral symptoms and resulting disability:
Fatigue. To counter problem behaviors resulting from fatigue, institutionalized patients should be given at least 2 rest or quiet periods at the same times every day. Calm times should be alternated with brief periods of activity. Caffeine should be avoided.
Responses to overwhelming or misleading stimuli. Many people with dementia tend to select the level of noise and social interaction they can tolerate, but in the nursing home they lose that control. Large dining roomswith their noise and high activity levelare especially troublesome. Patients may do better eating in small groups, which tends to decrease agitation and enhance food consumption. As dementia progresses, patients may misinterpret stimuli from television, radio, photographs, and mirrors . Caregivers should look for these cues and remove the environmental offenders.
Delirium. Patients with dementia should be monitored constantly for signs of pain, discomfort, urinary infection, trauma, and adverse drug reactions.

Caring For Someone With Dementia
Caring for a person with dementia can be physically and emotionally demanding. Anger, guilt, frustration, discouragement, worry, grief and social isolation are common.
Learn as much about vascular dementia as you can. Ask the primary care doctor or neurologist about good sources of information. Your local librarian also can help you find good resources.
Take care of yourself. See your doctors on schedule, eat healthy and exercise.
Seek support. People with dementia and their families benefit from counseling or local support services. Contact your Alzheimers Association local affiliate to connect with support groups, resources, referrals, home care agencies, residential care facilities, telephone help lines and educational seminars.
Encourage. You can help a person cope with vascular dementia by listening, reassuring them that life can be enjoyed and helping them retain dignity and self-respect.
Provide a calm environment. It can reduce worry and agitation. Establish a daily routine that includes comfortable activities for the person with vascular dementia.
New situations, excess noise, large groups of people, being rushed to remember or being asked to do complicated tasks can cause anxiety. As a person with dementia becomes upset, the ability to think clearly declines even more.
Paying attention to your needs and well-being is one of the most important things you can do for yourself and the person in your care.
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.

Can Dementia Get Worse Suddenly
Dementia is a progressive condition, meaning that it gets worse over time. The speed of deterioration differs between individuals. Age, general health and the underlying disease causing brain damage will all affect the pattern of progression. However, for some people the decline can be sudden and rapid.

Tests For Vascular Dementia
There’s no single test for vascular dementia.
The tests that are needed to make a diagnosis include:
- an assessment of symptoms for example, whether these are typical symptoms of vascular dementia
- a full medical history, including asking about a history of conditions related to vascular dementia, such as strokes or high blood pressure
- an assessment of mental abilities this will usually involve several tasks and questions
- a brain scan, such as an MRI scan or CT scan, to look for any changes that have happened in your brain

How Is Vascular Dementia Treated
Because many different disease processes can result in different forms of vascular dementia, there may not be one treatment for all. However, vascular dementia is often managed with medications to prevent strokes and reduce the risk of additional brain damage. Some studies suggest that medications that are used to treat Alzheimer’s might benefit some people with an early form of vascular dementia. Treating modifiable risk factors like high blood pressure, diabetes, high cholesterol, and problems with the rhythm of the heartbeat can help prevent additional stroke. Living a healthy lifestyle is important to help reduce the risk factorsof vascular dementia.
How Is Vascular Dementia Diagnosed And Treated
To diagnose vascular dementia, a doctor may ask about problems with daily activities, conduct memory or thinking tests, and speak with someone who knows the person well to see if symptoms of dementia are present. Medical history, lifestyle, and brain imaging tests are often used to help determine whether vascular dementia is the cause of symptoms.
No treatments are available to reverse brain damage that has been caused by a stroke. Treatment for vascular dementia focuses on preventing future strokes. Medications to prevent strokes, such as blood thinners, may help decrease the risk of further damage to the brain. Medications that help treat the symptoms of Alzheimer’s disease might benefit people with early vascular dementia. A doctor may also recommend treating risk factors, such as high blood pressure or high cholesterol, through medications and lifestyle changes.

Symptoms Of Vascular Dementia
Symptoms of vascular dementia depend on what part of the brain is affected and to what extent. Like Alzheimer’s disease, the symptoms of vascular dementia are often mild for a long time. They may include:
Symptoms that suddenly get worse often signal a stroke. Doctors look for symptoms that progress in noticeable stages to diagnose vascular dementia. Alzheimer’s, by comparison, progresses at a slow, steady pace. Another clue is impaired coordination or balance. In vascular dementia, problems walking or balancing can happen early. With Alzheimer’s, these symptoms usually occur late in the disease.

Behavioral And Psychological Disturbances In Alzheimer Disease: Assessment And Treatment
Behavioral and psychological symptoms of dementia can be the most challenging problems that caregivers face. While the symptoms are common, the literature on prevalence and treatment is riddled with varying definitions and measurements. Treatments include both nonpharmacological and pharmacological approaches. The basis of all successful management is careful definition of the problem and monitoring of interventions for effects and side effects in order to maximize the function of the patient and minimize the stress to the caregiver.
Determining the origins of behavioral problems can help caregivers deal with some of the distress experienced by patients with dementia.
Alzheimer disease is not a disease of cognition alone. A wide array of behavioral and psychological problems are associated with it. In fact, delusional jealousy, paranoia, auditory hallucinations, screaming, and agitation were all prominent features of the dementia described by Alzheimer in his original report. Behavioral disturbances may be the most challenging problems for caregivers to deal with and often lead to a need for institutional care. The origin of the problems needs to be understood before defining patient-centred management strategies.
Definitions and origins of behavioral problems
The term behavioral disturbance refers to a behavioral or psychological syndrome or a pattern associated with subjective distress, functional disability, or impaired interactions with others or the environment.
Symptoms And Signs Of Vascular Dementia
The Hachinski Ischemic Score is sometimes used to help differentiate vascular dementia from Alzheimer disease .
The diagnosis of CADASIL and CARASIL can be confirmed by genetic tests, which identify characteristic mutations of the NOTCH3 gene for CADASIL and HTRA1 gene for CARASIL. Sometimes a skin biopsy can be done instead to confirm the diagnosis of CADASIL.

Antipsychotic Use Across Dementia Sub
The use of antipsychotics is common in the natural history of dementia to treat behavioral disturbances, although their use may cause additional morbidity and disability in patients with pre-existing clinical vulnerability. It is well known that antipsychotics are associated with worsening cognitive performance, disability, increased caregiver burden, unfavorable clinical outcomes, including falls, anticholinergic burden and delirium , hypotension, sedation, and extrapyramidal symptoms. The 2016 American Psychiatric Association Practice Guidelines provided recommendations for the treatment of agitation or psychosis in patients with dementia, suggesting a comprehensive, person-centered, non-pharmacological approach .
In line with that, Wang et al. categorized three main types of non-pharmacological interventions including, respectively, sensory, cognition and movement-oriented approaches to assess the quality of evidence in treating BPSD in patients with dementia. Indeed sensory-orientated interventions reported the most consistent clinical benefits however, the ability of the person with dementia to fulfill the requests and to participate successfully in the approach underpinned how tailored interventions are needed for these patients, on the basis of their individualized cognitive abilities.

Causes Of Vascular Dementia
Vascular dementia is caused by reduced blood supply to the brain due to diseased blood vessels.
To be healthy and function properly, brain cells need a constant supply of blood to bring oxygen and nutrients. Blood is delivered to the brain through a network of vessels called the vascular system. If the vascular system within the brain becomes damaged – so that the blood vessels leak or become blocked – then blood cannot reach the brain cells and they will eventually die.
This death of brain cells can cause problems with memory, thinking or reasoning. Together these three elements are known as cognition. When these cognitive problems are bad enough to have a significant impact on daily life, this is known as vascular dementia.
Dementia and the brain
Caregiving And Vascular Dementia
There are many ways to help your family member or friend maximize his or her independence and cope with the cognitive symptoms of vascular dementia. Unlike Alzheimerâs disease, individuals with vascular dementia might better remember things in their daily life when repetition and context are provided. Likewise, simple cues can jog recall when remembering is difficult for the person. Structured and predictable routines can be helpful. Assistive devices and technology, such as pill boxes or electronic reminders on a phone, might be useful as well.
Breaking down complexânow overwhelmingâtasks into smaller and more manageable steps will make them easier to complete. Itâs also useful to simplify explanations and directions. As the disease progresses, even tasks learned years ago, like shaving or brushing teeth, may require step-by-step directions.
Problems with attention can make focusing and concentrating more difficult for your family member. Ensuring an environment that is not overly busy or noisy will make it easier to pay attention. Multi-tasking can be particularly difficult. Individuals with vascular dementia might have an easier time completing tasks when they focus on a single activity at a time, instead of dividing their attention between multiple tasks.
