Dementia is not one disease, but rather a group of symptoms affecting memory, social abilities, and thinking that interfere with daily functioning. Memory loss alone does not indicate dementia. There must be a problem with a least two brain functions, such as memory loss combined with the inability to perform daily tasks, and impaired judgment or language. The causes of Dementia are sometimes reversible, such as vitamin deficiency.
Other symptoms include personality changes, paranoia, or inappropriate behavior. Because dementia involves the nerve cells in the brain, it affects everyone differently depending on which areas of the brain are involved.
Alzheimer’s disease which is the most common cause of progressive dementia, and Vascular dementia which is caused by restricted blood flow to the brain, are not reversible and worsen over time. It is very important to have a doctor determine your exact type of dementia so a treatment plan can be put into action.
