Poverty is a good indicator of the rate of infectious diarrhea in a population. This association does not stem from poverty itself, but rather from the conditions under which impoverished people live. The absence of certain resources compromises the ability of the poor to defend themselves against infectious diarrhea. "Poverty is associated with poor housing, crowding, dirt floors, lack of access to clean water or to sanitary disposal of fecal waste ( sanitation ), cohabitation with domestic animals that may carry human pathogens, and a lack of refrigerated storage for food, all of which increase the frequency of diarrhea... Poverty also restricts the ability to provide age-appropriate, nutritionally balanced diets or to modify diets when diarrhea develops so as to mitigate and repair nutrient losses. The impact is exacerbated by the lack of adequate, available, and affordable medical care." 
Theresa, this info may assist you. Before I came to this site, I made notes from the blog of a male physician who had self treated his issue with Lichen as it related to Phimosis (tight penis foreskin) for which I am assisting my partner to treat (along with Type 2 Diabetes). This physician followed a low oxalic diet and noticed a 50% improvement in 2 weeks. He then added a multi species probiotic (in his case VSL#3) for 4 weeks to obtain a 98% recovery. He then rubbed on a small amount of coconut oil and obtained a 100% recovery. All symptoms had recovered.
After the double-murder suicide, former wrestler Christopher Nowinski contacted Benoit's father, suggesting that years of trauma to his son's brain may have led to his actions. Tests were conducted on Benoit's brain by Julian Bailes, the head of neurosurgery at West Virginia University, and results showed that "Benoit's brain was so severely damaged it resembled the brain of an 85-year-old Alzheimer's patient." He was reported to have had an advanced form of dementia, similar to the brains of four retired NFL players who had suffered multiple concussions, sank into depression, and harmed themselves or others. Bailes and his colleagues concluded that repeated concussions can lead to dementia, which can contribute to severe behavioral problems.
