  • Lewy body Dementia- The second most common cause of Dementia is Lewy body dementia often called as Dementia with Lewy bodies. It is a type of progressive dementia the effect of which increases with the passage of time. In Lewy body dementia the person might suffer with visual hallucination and other symptoms which are mostly similar to Parkinson’s disease.

Each person suffering from dementia is different depending on which part of the brain and how much of the brain is damaged. There are certain factors which caused dementia that can neither be changed nor be altered such as:

  • Family History- If Dementia run’s in your family it puts you at a higher risk of developing the problem. However this is not always true, there has been umpteen number of cases where the individuals have not developed Dementia even though it runs in their family.
  • Age- The risk of developing dementia increases with the age, especially after 65, and there is practically nothing much you can do about it apart from giving support to the seniors and taking the medicines as prescribed by the doctors. However, this is not a normal process of aging, dementia might also occur to people in their 40’s.

What are the Prevention from Dementia?

There doesn’t exist a silver bullet to cure or prevent dementia from occurring but there are certain habits that you must include in your life style that might help. These are as follows:

  •     Keep your brain active
  •     Quit smoking as soon as you can
  •     Get good quality sleep

Dementia effects every person differently, how they behave or how dementia affects them, depends upon which part of their brain is damaged. Dementia might also alter person’s personality, so you might experience a person who has been energetic and active its entire life may become dull and lethargic or someone who has always been jovial and pleasant may become rude and aggressive, but the one thing which you should always remember is that “They may not be able to remember who you are but they will feel you just the same”
