The most common symptoms of vascular dementia during the early stages are: problems with planning or organising, making decisions or solving problems. difficulties following a series of steps (such as when cooking a meal) slower speed of thought.
When it results from a stroke, symptoms are more likely to begin suddenly. About 20% of people who suffer a stroke will develop vascular dementia within six months. Whether or not changes in thinking, memory, or mental ability occur will depend on the area of the brain the stroke affected.
Magnetic resonance imaging (MRI).
MRI s are generally the preferred imaging test because MRI s can provide even more detail than CT scans about strokes, ministrokes and blood vessel abnormalities and is the test of choice for evaluating vascular dementia.
Introduction: The five-word test (5WT) is a serial verbal memory test with semantic cuing. It is proposed to rapidly evaluate memory of aging people and has previously shown its sensitivity and its specificity in identifying patients with AD.
The Mini-Cog test.
A third test, known as the Mini-Cog, takes 2 to 4 minutes to administer and involves asking patients to recall three words after drawing a picture of a clock. If a patient shows no difficulties recalling the words, it is inferred that he or she does not have dementia.
As a person's vascular dementia progresses, they may begin to behave in ways that seem out of character. For example, they may become more agitated or aggressive, or have sleep problems. They may also act in ways that others find embarrassing or difficult to understand.
Vascular dementia is generally caused by conditions that occur most often in older people, such as atherosclerosis (hardening of the arteries), heart disease, and stroke. The number of people older than 65 years is increasing. People are living longer with chronic diseases, such as heart disease and diabetes.
On average, people with vascular dementia live for around five years after symptoms begin, less than the average for Alzheimer's disease. Because vascular dementia shares many of the same risk factors as heart attack and stroke, in many cases, the person's death will be caused by a stroke or heart attack.

It is quite common for a person with dementia, especially in the later stages, to spend a lot of their time sleeping – both during the day and night. This can sometimes be distressing for the person's family and friends, as they may worry that something is wrong.
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.
In most cases, vascular dementia itself is not inherited.
Other than in a few, very rare cases, parents cannot pass on vascular dementia to their children. However, a parent may pass certain genes that increase the risk of developing vascular dementia.
The current evidence indicates that while chronic stress may play a role in the development or progression of dementia, it does not necessarily cause dementia. Hopefully, further research can begin to uncover what role stress plays in a person's risk of developing dementia.
More Evidence That Alzheimer's Disease May Be Inherited from Your Mother. Results from a new study contribute to growing evidence that if one of your parents has Alzheimer's disease, the chances of inheriting it from your mother are higher than from your father.
Key points about vascular dementia
Symptoms can include problems with memory and focus, confusion, changes in personality and behavior, loss of speech and language skills, and sometimes physical symptoms such as weakness or tremors. Vascular dementia tends to get worse over time.
The clock test is a non-verbal screening tool that may be used as part of the assessment for dementia, Alzheimer's, and other neurological problems. The clock test screens for cognitive impairment. The individual being screened is asked to draw a clock with the hour and minute hands pointing to a specific time.
A list of ten unrelated words are orally presented one by one, and subjects are instructed to recall as many items as possible immediately after their presentation (immediate free recall, the traditional span task) and after a predetermined time, in general 5 to 10 minutes (delayed free recall).
Lewy body dementia causes a progressive decline in mental abilities. People with Lewy body dementia might have visual hallucinations and changes in alertness and attention. Other effects include Parkinson's disease signs and symptoms such as rigid muscles, slow movement, walking difficulty and tremors.
A 2019 study published in Journal of Alzheimer's Disease, showed among 165 participants (45 with diagnosed neurodegenerative disease, 120 controls) a supine sleep position (on back, head at body level) for more than 2 hours per night increased the risk of dementia by almost four times (3.7 times greater).
The Montreal Cognitive Assessment (MoCA) is a tool that helps healthcare professionals detect mild cognitive impairment and Alzheimer's disease in people. A 2021 study found that it is a better measure of cognitive function than the MMSE. It consists of 30 questions that take 10–12 minutes to accomplish.
In the early stages of dementia, many people are able to live at home and enjoy life in the same way as before their diagnosis.
