Alz =1 type dementia. The term 'dementia' describes a set of symptoms which include loss of memory, mood changes, and problems with communication and reasoning. These symptoms may occur when the brain is damaged by certain diseases. Alzheimer’s is the most common (but not the only) cause of dementia.
Dementia. Can be caused by a númer of things, one of which is alzheimer's disease. Other causes include alcohol, stroke, head injuries, Parkinson's disease and others.
Alzheimer's is. A very specific and the most common form of dementia. Dementia can be caused by several other factors, many of which can be controlled, at times even reversed.
Dementia types. Alzheimer's disease is one type of dementia. It is a neurodegenerative dementia, which cannot be reversed and gradually worsens over time. However, some medications can help to slow the process. Other types of dementia include fronto-temporal dementia, lewy body dementia, and vascular dementia. Some dementias can be treated, so proper diagnosis is important.
Dementia is general. Dementia describes a collection of brain symptoms including memory impairment, problems using or understanding words, loss of functioning and judgement and other symptoms. Alzheimers disease is the most common type of dementia, nearly 70% of those with dementia have alzheimers and age is the biggest risk factor. Other types of dementia include vascular, lewy body, alcoholic, and parkinsons.
AD is a dementia. Dementia describes a collection of brain symptoms including memory impairment, problems using or understanding words, loss of functioning and judgement and other symptoms. Alzheimers disease is the most common type of dementia, nearly 70% of those with dementia have alzheimers and age is the biggest risk factor. Other types of dementia include vascular, lewy body, alcoholic, and parkinsons.
Vascular vs. Alzheim. Alzheimer is diagnosis by exclusion, when other physiologica causes are ruled out, vascular is by abnormality in blood system suchas high blood pressure or stroke, etc.
The course. Vascular dementia may be caused by small strokes from which the person may partially recover. So the course of vascular dementia is like a staircase. Alzheimer's disease is usually more gradual progression of dementia although people may have good and bad days.
Neuropsych eval. There are different characteristics for each type of dementia that maybe very clear to a doc or may need further eval by a neuropsychologist. A clinician well versed in management of dementias can usually diagnose with a physical and complete medical eval.
Hints no clear rules. Alzheimer's usually impairs recent memory initially, with preservation at first of distant memory and other cognitive functioning. Eventually more global deficits occur. Often ad is a "diagnosis of exclusion" i.e., the most likely possibility after other causes are ruled out. It can only be diagnosed for certain with brain tissue samples, which is generally only done after death.
The only way to be. Sure is after death with examination by a pathologist.
Not many. Clinically, alzheimer's tends to be a smooth decline over time, while vascular dementia declines in steps, as small regions of the brain lose function. Neuropsychological testing may lend evidence for, but not prove, one cause or the other. A definitive diagnosis can only be made by brain biopsy (which is rarely done), or at autopsy.
The course of illnes. Is one of the major differences. Vascular dementia shows a stepwise loss of memory and function, while alzheimer's course is slowly progressive.
See below. Vascular dementia usually has more sudden onset due to the inadequate blood flow. Below is more detailed description of the disease. Http://www. Alz. Org/dementia/vascular-dementia-symptoms. Asp.
Briefly, Ad progresses slowly, but it does progress. Vd occurs suddenly and stabilizes. With additional incidents, it again abruptly worsens, then stabilizes. Depending on the site of the damage, motor function will or will not be involved. Ad may take a long time to effect motor ability. It's a bit like "disease vs injury".

Difference. Think alzheimer's in terms of changes to brain structure. Think of dementia in terms of change of blood flow.
