Alzheimer’s disease has risen to be the fourth leading cause of death behind cancer, diabetes, and heart disease. However, Alzheimer’s is often not listed as a contributing factor on death certificates. Research on Alzheimer’s and has found that there may be a link between cholesterol and the increase of people with the disease. One out of every two Americans that reach the age of 70 have a 50 percent chance of getting Alzheimer’s in their remaining lifetime. Since senile dementia is often diagnosed as Alzheimer’s disease, there is truth behind these claims. Although a decrease in cholesterol may cause senile dementia, or Alzheimer’s, the symptoms could be reversed by consuming certain nutrients.
