Large amounts of people who are diagnosed with dementia have been found to have Lewy bodies in the nerve cells in their brain. These Lewy bodies are considered to be a catalyst for the death of the cells, which in turn brings on dementia. In this type of dementia, the symptoms will fluctuate wildly in severity from day to day – some days there will be no symptoms at all, and other times the symptoms will be so strong it’ll be difficult to function. Lewy bodies can occur with any of the other forms of dementia, most notably Alzheimer’s and vascular dementia.

Korsakoffs syndrome – also known as alcohol dementia, is a less common form of dementia. This form of dementia is completely preventable. Essentially what happens is that since alcohol is a poison, when you ingest too much of it, it can cause irreversible brain damage. The most susceptible part of the brain is the part that is responsible for memory, planning and organizing, social judgment, as well as other social skills and balance. This form is completely preventable, which is why you should always drink only a small, safe amount of alcohol.

Frontotemporal dementia (FTD) deals with a few related forms of dementia, which begin in the brain’s frontal lobe, temporal lobe or both. The symptoms have a wide variety, depending on which part of the brain is affected. Usually this form of dementia will occur prior to Alzheimer’s disease, and there may be a change in the victim’s personality or language. Eventually this form of dementia will progress, and enter other areas of the brain.

There are several different signs of dementia, and if you have any of the symptoms you should go to your doctor immediately: frequent memory loss, additional confusion, a change in personality, withdrawal and apathy, and you’ll be unable to do normal, everyday tasks. Once again, if you have any of those symptoms, it may be the onset of dementia.
