what is the difference between vascular cognitive impairment and vascular dementia?
479
Vascular cognitive impairment is a disorder of the mind – the mental ability to be aware, to think and to feel. VCI symptoms can range from forgetfulness to more serious problems with attention, memory, language, and executive functions like problem solving. The most serious form of VCI is called vascular dementia.

No particular dementia etiology (degenerative or vascular) predominated in one group over the other. In the TGA group, there was also no evidence of an association between TGA recurrence and cognitive impairment (P=77), cerebrovascular event (P=71), or seizures (P=46).

Dementia. While some mild changes in cognition are considered a normal part of the aging process, dementia is not. Normal age-related declines are subtle and mostly affect the speed of thinking and attentional control.

7﻿ There is not usually a sudden, significant change from one day to the next. In contrast to the step-like decline in vascular dementia, Alzheimer's is typically more like a slight, downward slope of a road over time.

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.

delirium: onset it usually sudden and severe. condition is typically brief (hours to days) but may persist for months. >dementia: irreversible and increasing loss of cognition and global brain function. ... delirium: restlessness; tremor; movement may be either slow or hyperactive.

On average, people with vascular dementia live for around five years after symptoms begin, less than the average for Alzheimer's disease. In many cases, the person's death will be caused by a stroke or heart attack.

Cardiovascular disease - and therefore vascular dementia - is linked to high blood pressure, high cholesterol and being overweight in mid-life. Someone can reduce their risk of developing these by having regular check-ups (over the age of 40), by not smoking, and by keeping physically active.

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.

Key differences between Alzheimer's and Lewy body dementia Hallucinations, delusions and misidentification of familiar people are significantly more frequent in early-stage Lewy body dementia than in Alzheimer's. REM sleep disorder is more common in early Lewy body dementia than in Alzheimer's.

Cardiovascular disease is a disease of the blood vessels in the heart, and cerebrovascular disease is a disease of the blood vessels in the brain.

Frontotemporal Dementia versus Alzheimer's Disease But Alzheimer's disease usually begins with memory loss, while FTD is typically a behavior or language disorder. The probability of AD is strongly affected by the age of the person showing the symptoms.

Dementia is an umbrella term used to describe a clinical syndrome of progressive cognitive decline, but its subtypes are classified according to the cause 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.

Age-related memory loss and dementia are very different conditions, though they may share some overlap in symptoms. However, normal forgetfulness is often caused by lack of focus and it never progresses into serious territory. Dementia, on the other hand, will get worse over time.

Hardening of the arteries, or atherosclerosis, is a natural part of aging, while Alzheimer's and other forms of dementia are not. A 1997 study was one of the first to link dementia and atherosclerosis, stating that people with severely hardened arteries were three times more likely to have dementia.

Dementia is the term applied to a group of symptoms that negatively impact memory, but Alzheimer's is a progressive disease of the brain that slowly causes impairment in memory and cognitive function.
