what is the difference between dementia and vascular dementia?
9427
The word dementia describes a set of symptoms that can include memory loss and difficulties with thinking, problem-solving or language. In vascular dementia, these symptoms occur when the brain is damaged because of problems with the supply of blood to the brain.

Major NCDs correspond to the condition also known as dementia, with significant cognitive decline present. Mild NCDs have similar symptoms to major NCDs, but the cognitive decline is modest rather than severe.

Alzheimer's disease is the most common cause of dementia in people older than age 65. Delirium is a sudden change in how well a person's brain is working (mental status). Delirium can cause confusion, change the sleep-wake cycles, and cause unusual behavior.

Dementia is a syndrome – usually of a chronic or progressive nature – in which there is deterioration in cognitive function (i.e. the ability to process thought) beyond what might be expected from normal ageing.

Delirium is typically caused by acute illness or drug toxicity (sometimes life threatening) and is often reversible. Dementia is typically caused by anatomic changes in the brain, has slower onset, and is generally irreversible.

Is dementia a mental illness? No, it is a condition of the brain. Our brain is our control centre and it controls everything we do and say and think. When the brain is sick we have problems with all our actions, including remembering, speaking, understanding and learning new skills.

While dementia does affect mental health, it is not a mental illness, but a disorder of the brain that causes memory loss and trouble with communicating. Proper diagnosis of mental illness or dementia in the elderly is vital in order ensure that appropriate treatment is provided as soon as possible.

If a blood cannot carry energy and oxygen to a part of the brain due to a blocked or burst blood vessel, some cells in the brain may be damaged, or even die. This damage can sometimes affect a person's memory, thinking, or language skills. This is called vascular dementia.

The actual death of a person with dementia may be caused by another condition. They are likely to be frail towards the end. Their ability to cope with infection and other physical problems will be impaired due to the progress of dementia. In many cases death may be hastened by an acute illness such as pneumonia.

How can I lower my risk of vascular dementia? Having high blood pressure is a risk factor for vascular dementia. If you can lower your blood pressure through lifestyle changes and medicines, you can reduce your risk. Vascular dementia is most commonly caused by the effects of a stroke.

Vascular dementia is a general term describing problems with reasoning, planning, judgment, memory and other thought processes caused by brain damage from impaired blood flow to your brain. You can develop vascular dementia after a stroke blocks an artery in your brain, but strokes don't always cause vascular dementia.

Dementia is an overall term used to describe symptoms that impact memory, performance of daily activities, and communication abilities. Alzheimer's disease is the most common type of dementia. Alzheimer's disease gets worse with time and affects memory, language, and thought.

Long-term research studies have demonstrated that high blood pressure in mid-life is a key factor that can increase your risk of developing dementia in later life, particularly vascular dementia. These findings highlight that a lifelong approach to good health as the best way to lower your risk of dementia.

Like Alzheimer's dementia, CTE is characterized by tangles of an abnormal form of the protein tau in the brain. Unlike Alzheimer's dementia, these tangles typically appear around small blood vessels, and beta-amyloid plaques are only present in certain circumstances.

Mild Dementia – Memory loss is moderate, especially for recent events, and interferes with daily activities. Average duration is 2 years. Moderate Dementia – More profound memory loss, only retaining highly learned material. Average duration is just under 2 years to 4 years.

Dementia is an umbrella term used to describe a range of progressive neurological disorders, that is, conditions affecting the brain. There are over 200 subtypes of dementia, but the five most common are: Alzheimer's disease, vascular dementia, dementia with Lewy bodies, frontotemporal dementia and mixed dementia.
