Vascular dementia develops when the blood vessels in the brain are damaged by other health conditions. This damage keeps the brain from getting the oxygen it needs.Vascular diseasessuch asatherosclerosisorhigh blood pressurecontribute to one-fourth to one-half of all cases of dementia. Vascular dementia often occurs in combination withAlzheimer’s disease dementiaor other dementias rather than just by itself. Cardiovascular research studies, or studies on the heart and blood vessels, are identifying other potential causes of dementia, such as problems in the heart’s chambers.

Dementia refers to problems with memory, thinking, behavior, language skills, and decision making, beyond what is expected during the healthy aging process.Early signs of vascular dementia can include symptoms such as mood and behavior changes. The decrease in blood flow to the brain that occurs with this dementiacan also cause problems with planning, memory, the ability to pay attention, and other thought processes.A healthcare provider may consider the following problems as signs of vascular dementia:

Forgetting to pay bills
	Getting lost in your neighborhood
	Having difficulty preparing meals
	Experiencing short-term memory loss

          
How is vascular dementia diagnosed?

            To diagnose vascular dementia and cognitive impairment, your healthcare provider may:

Ask about any symptoms you have, such as problems carrying out daily activities
	Give you brief memory or thinking tests
	Ask to speak with a relative or friend who knows you well and can answer questions about your daily habits and behaviorTo find out if vascular dementia is the cause of any cognitive impairment or other dementia that you experience, your provider will review your medical history, including cardiovascular risk factors such as blood pressure and cholesterol levels. They may also ask about your lifestyle, including eating patterns, physical activity level, sleep health, and whether you are or have been a smoker. They may also order imaging tests.

Diagnosis can take time. It can be hard to tell whether symptoms are a result of blood vessel problems, as is the case with vascular dementia, or whether they are from another cause, such as Alzheimer’s disease.

          
What causes vascular dementia?

            Vascular dementia is caused by conditions that damage the blood vessels in the brain or interfere with blood flow and oxygen delivery to the brain. This oxygen shortage keeps the brain from working as well as it should. For example, astrokemay block blood flow to the brain and lower oxygen levels.Atherosclerosisin the brain’s blood vessels also can lead to vascular dementia.



Other risk factors for vascular dementia include:



High blood pressure
	High cholesterol
	Atrial fibrillation
	Diabetes
	Smoking

          
How is it treated?

            Currently there are no treatments that reverse dementia, but there are ways to manage your symptoms. If you are diagnosed with vascular dementia, your treatment plan may include taking medicine or using medical devices to manage any other conditions that can cause your vascular dementia to get worse. Those other conditions may include high blood pressure,atherosclerosis, or sleep apnea.

Some studies suggest that medicines that improve memory in people living with Alzheimer’s disease might benefit people experiencing early vascular dementia. Other medicines may help manage certain symptoms and behavioral issues associated with vascular dementia.

Your healthcare provider may also recommend that you makeheart-healthy lifestyle changes. These includeeatinga heart-healthy diet, limiting alcohol, getting regularphysical activity, aiming for ahealthy weight,quitting smoking, controlling diabetes, andmanaging stress.
