Dementia is an umbrella term used to describe the symptoms that pertain to a large number of illnesses that could cause for eventual progressive decline in the mental functioning of a person.

Although most cases of dementia will end up affecting people who are elderly, there have been the occasional off cases where people who are younger have also been diagnosed with dementia.

According to some experts, this form of dementia is said to progress much more rapidly. However, the cynics argue that this disease is said to just appear as though it is advancing faster in those who suffer from younger onset dementia because the people in question being affected are younger; and hence, healthier. This makes the deterioration seem stark and noticeable.
