Vascular dementia is the second most common type of dementia after Alzheimer's disease, which affects around 150,000 people in the UK, according to the NHS. This type of dementia is caused by reduced blood flow to the brain, which damages and eventually kills brain cells. But who is most at risk of this happening? The Mayo Clinic lists nine risk factors for vascular dementia.
Like other types of dementia, aging can be a risk factor.
The Mayo Clinic advises: "The disorder is rare before the age of 65 and their increase substantially increases by 90 years."
Heart attack, stroke or Ministrokes
If you have had a heart attack, you may be at increased risk of having blood vessel problems in the brain, according to the Mayo Clinic.
He adds: "The brain damage that occurs with a stroke or ministerke (transient ischemic attack) can increase the risk of developing dementia."
Abnormal aging of blood vessels
Also known as atherosclerosis, the codlin occurs when deposits of cholesterol and other substances accumulate in narrow arteries and blood vessels.
The Mayo Clinic states: "Atherosclerosis can increase the risk of vascular dementia by reducing the flow of blood that nourishes the brain."
Having high cholesterol can increase the risk of many serious health conditions.
The Mayo Clinic recommends: "High levels of low-density lipoprotein (LDL), the" bad "cholesterol, are associated with an increased risk of vascular dementia".
High blood pressure
When blood pressure is too high, stress on the blood vessels throughout the body, including the brain, increases.
The Mayo Clinic states: "This increases the risk of vascular problems in the brain".
Having high blood sugar levels damages blood vessels throughout the body.
Damage to cerebral blood vessels can increase the risk of stroke and vascular dementia, according to the Mayo Clinic.
Smoking directly damages blood vessels, increasing the risk of atherosclerosis.
The Mayo Clinic adds that it can also increase the risk of other circulatory diseases, including vascular dementia.
Being overweight is a risk factor for vascular diseases and the Mayo Clinic says it presumably increases the risk of vascular dementia.
This is the term used for an abnormal heart rhythm, when the upper chambers of the heart begin to beat rapidly and irregularly.
The Mayo Clinic explains: "Atrial fibrillation increases the risk of stroke because it causes the formation of blood clots in the heart that can break off and go to the blood vessels of the brain."
Although age cannot be prevented, other risk factors can be reduced by making some simple lifestyle changes, such as quitting smoking, exercising regularly, and following a healthy and balanced diet.
Memory loss is one of the most recognized symptoms of vascular dementia, along with disorientation and problems with communication.
But according to Alzheimer's Research UK, there may also be more specific symptoms and these will differ depending on the area of the brain involved.
