We certainly wish that we could say that this was true, but it is simply not the case. To gain a thorough grasp on the subject, you have to understand the widespread nature of Alzheimer’s disease.
The Alzheimer’s Association tells us that the disease strikes about 10% of all people that are 65 and older, and the figure rises to 40% for those even older, at least 85. It should be noted that the oldest segment of the population is growing faster than any other.
Alzheimer’s alone is enough to make you sit up and take notice, and it is not the only cause of dementia. Plus, there are other forms of incapacity outside of cognitive impairment.
