When it comes to Dementia life expectancy, there are some doctors and related professionals who will throw a definite number on the table. The fact is, though a definite number might be an average, a great number of things go into this issue of life expectancy. This sickness also effects every single person differently. The only sure way is to study case after case and then come up with definite answer, but if everyone did this everyone will have a different answer.
For the record, life expectancy concerning this sickness is approximately four to six years. These statistics are generated according to all of the people affected by this sickness from the time they are diagnosed. However, there are some people who only survive the first two years, and then there are those people who have survived ten or even twelve years. This depends on the person. Someone in an environment where they are happy, with their family, and have great doctors are known to have a high success rate of staying alive longer. Laughing a lot also helps a person live longer because, for some reason, it helps people remember more. Many people with this sickness die when their memories die, and that is why laughter is important.
Those people who are around negativity, yelling and screaming, and no love are known to have a shorter life expectancy. There are certain things that trigger the sickness to work faster and certain things to trigger the sickness to work slower. The same is true for the sick individual: certain behaviours will help the body fight off the sickness, but certain behaviours will not help the body fight off sicknesses. At the end of the day, there have been affected people with great families whom have died in one or two years; there have also been affected people whom have had no families and made it through ten years. This goes back to the strength a person carries within them on an everyday basis for the duration of their sickness.
This sums of the life expectancy though worldwide, and it also explains the different levels this expectancy encounters even though a definite number has been chosen.
