Hello friend @ Abigail-dantes, very interesting its publication. It is really very informative that there is not much talk about cases of dementia in society, it is a taboo, I am very struck by the short period of life that a person suffering from these diseases can experience.

Bill is likely to live 10 to 15 years from the start of his illness.

It is a very short period of time and in which all the abilities that a person can have both physically and cognitively are lost, thus being incapacitated and dependent on their relatives, this disease is very sad. But it is very good to know that you can do some things, such as low sugar diet, exercise, perform some activities where our mind is active among others.
Thank you very much for this valuable information, from now on try to implement these recommendations.
