The difference between a person with alzheimer's and dementia

[sena2gurl]

While the most common cause of dementia is Alzheimer's Disease, there are other less common causes. The second most common cause is vascular dementia, which results when strokes or brain lesions impair blood flow to the brain. Other primary causes include Parkinson's Disease, Huntington's Disease and Pick's Disease. Dementia-like symptoms also can develop as a result of another condition, such as alcohol or substance abuse, vitamin deficiency and certain infectious diseases.

so inshort dementis can occur from almost all the brain deseases. is it only memory loss something more than that? does a person has total memory loss or somethig wlse please tell.

[zinta]

I think the inability of a person to learn something from his childhood is a genetic cause and this might happen because his/ her parents are suffering from this type of disease....

Diseases, such as Parkinson's disease, dementia with Lewy bodies, and frontotemporal dementia.
